The following is a reference for setup and operation of the described flare system. This
information should be used in conjunction with facility safety practices and work protocols.
WARNING
All facility safety procedures and guidelines must be followed during the installation of the flare
stack. Coordinate with site safety personnel to determine what precautions must be taken
before beginning any installation of or repair to the system.
If site operators are not comfortable with the setup and operation of flaring equipment, it is
recommended that Zeeco Global Field Services be contacted for any questions, installation
services, or support for commissioning/training.

Equipment Installation
The following sections outline the steps and recommended practices to successfully assemble
and erect the described flare system.
WARNING
The supplied equipment may contain components and parts with small ports/openings that can
become plugged. It is mandatory and critical to proper operation that all components and
piping of the system be blown out and inspected to be free of scale, debris, trash, liquids, etc.
All aspects of the system installation should be governed by the field installation crew. The field
installation crew should familiarize themselves with the local safety procedures and regulations
governing this installation.
Zeeco flare stack assemblies utilize one of two base types: Foundation-mount ring and Skid. If
the stack assembly uses a Foundation-mount base ring, the stack should be installed on an
appropriately designed foundation pad. The design and installation of the referenced
foundation pad is the responsibility of the customer/end-user. If the stack assembly uses a Skid
base, it is common to install the flare stack assembly on either a foundation pad or directly on
grade. If installing the stack assembly directly on grade, the below recommendations are
offered:
• Remove loose debris and any problematic soil (e.g. high expansive clays) in the area
near the flare stack assembly
• Level and compact soil to 95% density (Proctor)
• Top 4”-6” to be compacted #2 limestone or crushed stone (typical)
• Area shall be properly drained, and considerations taken such that area will not hold
standing water at any time
• Grade shall not have a slope exceeding 1° witnessed; Zero (0°) slope is highly preferred
• If necessary, helical piers or other acceptable means of anchorage/support may be used
It is recommended that either before the stack erection process begins, or simultaneous to the
steps outlined below, the guy wire system anchors be installed. This is recommended to reduce
the required amount of crane time at site.
Stack Assembly
Sections of the flare stack assembly should arrive in a horizontal configuration on freight carrier
trailers. Wherever possible, stack sections will be oriented on the trailer deck such that the
section can be lifted directly vertical and placed onto assembly supports without the need to
rotate the section along the longitudinal axis. In some cases, sections may have constraints
during shipping to avoid damage to attachments and may require rotation as part of the
offloading process.
4
Before offloading stack sections onto assembly supports, care should be taken by the field
installation crew to identify the best location for assembly relative to the lifting process and
final target location for placement of the flare stack base.
As stack sections arrive and are prepared for offloading, refer to Zeeco project drawings and
any relevant markings on stack sections to identify the proper assembly configuration. The
temporary flare stack assembly is designed such that a top section (including flare tip), base
section, and middle section(s) are used to complete configurations of varying heights. The stack
assembly is designed to be modular such that middle sections can be added or removed to
achieve the desired height configuration for the designed application.
After all stack sections have been identified, offloaded, and placed on assembly supports,
appropriate fasteners and hardware can be retrieved from the provided Zeeco job box. The
provided job box will contain all necessary hardware, fasteners, gaskets, fittings, guy wire
components, etc. for proper assembly of the flare system.
Stack sections should be fit-up and alignment of all utilities and flange connections verified.
Flanged stack connections should be made using the provided hardware and gasket materials.
Torque values and bolting patterns should be in accordance with gasket manufacturer
recommendations and typical industry practice on raise face flanged connections. After each
flanged connection is made, a flange torque record sheet entry should be made as part of the
installation documentation package.
Depending on the application, the flare stack assembly may also be using one or more external
risers for assist media. Follow the same protocol as established by the field installation crew for
connecting external riser sections together after the applicable stack joint is made. Care should
be taken to review the project drawings and mechanical connection points for the external
riser(s) to properly utilize any ANCHOR or GUIDE supports as intended.
WARNING
External riser sections will be tightly anchored to their supports for transit purposes. When
assembly takes place, it is critical that all external riser fasteners (u-bolt typical) be loosened
and properly anchored to serve as a GUIDE in the proper locations in accordance with project
drawings. Common practice is to remove double nuts on u-bolt, remove u-bolt, install nuts such
that they tighten on either side of support material creating a rigid loop that is not tightly
affixed to external riser piping. This allows riser piping to move if needed due to thermal
expansion or other forces.
Once all stack sections are assembled together, the pilot gas line should be connected across
the entire assembly. Starting at the flare tip, the top section of the stack should already have
the pilot gas line connected to the pilot manifold and mounted to the appropriate utility
brackets. Following the line down the stack, connections will need to be made using the
appropriate threaded hardware near each stack joint. Depending on shipping configuration,
pilot gas line sections may need to have the fasteners loosened to allow adjustment of each
5
pilot gas piping run to allow for successful mate up with the adjacent piping run. Once all
sections are connected, the pilot gas spool inlet at the base of the flare stack assembly should
be at or near the elevation listed on the project drawings. Care should be taken to review the
project drawings and mechanical connection points for the external riser(s) to properly utilize
any ANCHOR or GUIDE supports as intended.
Installation of Retractable Tubing and Components
Zeeco rental pilots are designed to be static with respect to the flare tip. The pilot is rigidmounted but the critical components (ignition and thermocouple probes) are designed to be
retractable from grade for ease of service/maintenance. The probes are retractable via
dedicated guide tubing runs routed up the stack.
The sections of flare stack will be outfitted to the greatest extent possible with utilities and
retractable tubing without risking critical damage during shipment. Depending on the stack
section design, some components (e.g. tubing sticks, fittings) may ship loose to protect integrity
prior to arrival at site.
When stack sections are aligned and assembled, utility brackets oriented under each pilot
should align with each other down the entire stack assembly from flare tip to base. These utility
brackets hold any relevant piping runs and the retractable guide tubing for both the ignition
and thermocouple probes. After stack sections are aligned and bolted together, the retractable
tubing can now be aligned and connected.
The brackets that support the tubing should align such that each tubing run is straight and free
of kinks or severe bends. Some sweeping bends are allowed but should not exceed a 10’ bend
radius whenever possible. The flare stack assembly is designed such that upper most bracket
(directly under the pilot connection) will serve as an ANCHOR for the retractable component
guide tubing. All other brackets running down the stack are to serve as a GUIDE only and will
not fit tight to the tubing.
WARNING
It is critical to verify on all tubing runs that the upper most bracket is tight, and all others are
loose. Failure to do so can result in damage to the guide tubing and the relevant probe inside.
Once all tubing connections are made, the applicable probes can be installed. It is
recommended to do the initial install while the stack assembly is in the horizontal position for
ease of installation. The ignition and thermocouple probes should be straightened to the best
of the user’s ability before inserting into the guide tubing. Many customers opt to use a
thermocouple straightening design for mechanical assistance during this effort.
Thermocouple Probes
The thermocouple probe should be inserted such that the lead end bottoms out in the
thermowell located in the pilot hood. Recommended practice is to install the thermocouple
6
probe in the guide tubing until the lead end bottoms out in the thermowell, mark the end of
the guide tubing on the probe (at base of stack) with a mark, then back the probe out and push
again to verify you have truly reached the end of the thermowell. Once set, tighten the
compression fitting located at the end of the guide tubing to lock the thermocouple probe in
place. The remaining probe length can then be looped over to the termination point on the
junction box assembly. Refer to project drawings for more details on wiring terminations.
Ignition (HEI) Probes
The ignition probes should be inserted such that the spark tip contacts the 90-degree bend in
the guide pipe on the pilot. Recommended practice is to install the ignition probe in the guide
tubing until the spark tip makes contact, mark the end of the guide tubing on the probe (at base
of stack) with a mark, then back the probe out and push again to verify you have truly reached
the bend in the pilot. Once finished, back the probe out such that the final mark is
approximately 1” from the end of the guide tubing. This should translate to the spark tip being
approximately 1” from the 90-degree bend in the guide pipe on the pilot. This is optimal
placement for reliable ignition. Once set, tighten the compression fitting located at the end of
the guide tubing to lock the ignition probe in place. The remaining probe length can then be
looped over to the termination point on the junction box assembly. Refer to project drawings
for more details on wiring terminations.
Stack Erection
All aspects of the erection of the system are the sole responsibility of the field installation crew
or lift contractor. The field installation crew or lift contractor should exercise good practice and
experience to decide how to safely and efficiently erect the system.
WARNING
Refer to Zeeco project drawings for designated lift and tailing points on the assembled flare
stack. Use of any other non-designated lift and tailing points could result in equipment failure
and/or personal injury.
7
After flare stack has been fully assembled, the field installation crew or lift contractor should
inspect the overall assembly and all parties should sign off prior to erection. It is also
recommended that a lift plan be drafted by the field installation crew or lift contractor,
reviewed by all parties, and sign off should occur prior to proceeding with erection.
The primary lift crane should be connected to the proper lifting trunnions on the flare stack
using acceptable lifting components at the discretion of the field installation crew or lift
contractor. Spreader bars or other acceptable means of lift alignment may be required to
successfully erect the stack.
WARNING
Lift connections on flare stack trunnions must not exceed +/- 10° from vertical at any point
during the erection process. Exceeding 10° of angle (relative to vertical centerline of trunnions)
could result in mechanical failure of the trunnion weldment.
The tailing crane should be connected to the proper tailing lug on the flare stack using
acceptable lifting components at the discretion of the field installation crew or lift contractor.
Final inspection should occur before the lift begins to ensure that lifting apparatuses will not
contact or interfere with any stack components or attachments. This is critical to ensure that no
undue damage occurs to the flare stack assembly which will require elevated repair work.
Guy Wire System (if applicable)
Refer to provided equipment drawings for guy wire information. Guy wire anchors must be
installed prior to completing the steps below.
Guy wire sockets should be connected to the appropriate guy lug locations on the flare stack
assembly prior to erection. While the stack assembly is vertical and before crane support is
released, guy wires must be installed and tensioned.
WARNING
“Never saddle a dead horse.”

WRONG
It is typical to tension guy wires using two common methods. One method is applicable for
stack systems with a single level of three (3) guy wires equally spaced in 120° increments
around the stack circumference. The second method is applicable for stack systems with one or
more levels of three (3) guy wires equally spaced in 120° increments around the stack
circumference. These methods are briefly outlined below.
8
Ultimate installation and tensioning practices are the responsibility of the field installation
crew.
WARNING
Do not over-tension guy wires. Increase tension slowly and deliberately. Do not go to full
tension immediately.
Method 1
Equipment: (2) Transit, (1) Tension Meter total
1. Gather all equipment necessary for tensioning including guy wires, turnbuckles, transits,
temporary wire, tension meter and chain block, winch or other tension adjuster.
2. Attach the three (3) guy wires from the flare stack to the appropriate anchors using
chain block, winch or other tension adjuster as necessary. At this time, turnbuckles
should be set in the maximum open position.
3. Set two transits, 90 degrees from each other, to ensure visual confirmation of the
verticality of the flare stack.
4. Set the tension meter on one of the three guy wires by using temporary wire and
tension adjuster, as shown in depiction below.
5. As you increase the tension on the tension meter, the stack will move from the vertical.
You will need to use the other turnbuckles located on the other two guy wires to move
the flare stack back to the vertical. The stack will be set when the tension meter reads
the required tension (refer to equipment drawings) and the stack is still vertical.
6. After the stack is set in place, make sure that the correct tension reading is shown on
the tension meter and (using the two transits) that the stack is vertical. The tension
meter can be removed by tightening the turnbuckle on the guy to which it is attached
until all tension is removed from the tension meter. Do not tension the guy wire any
more than is necessary to remove all tension from the tension meter. You may then
loosen the turnbuckle attached to the tension meter and remove all tension meter
components.
Method 2
Equipment: (0) Transit, (1) Tension Meter per guy wire
1. Gather all equipment necessary for tensioning, including guy wires, turnbuckles,
temporary wire, tension meters and chain block, winch or other tension adjuster.
2. Attach each guy wire from the flare stack to the appropriate anchor using chain block,
winch or other tension adjuster as necessary. At this time, turnbuckles should be set in
the maximum open position.
3. Set a tension meter on each guy wire by using temporary wire and tension adjuster, as
shown in depiction below.
4. Incrementally increase the tension on each tension meter, one after another, taking care
to prevent the stack from moving from the vertical. The stack will be set when all tension
meters read the required tension (refer to equipment drawings) and the stack is vertical.
9
5. After the stack is set in place, make sure that the correct tension reading is shown on all
tension meters. Each tension meter can be removed by tightening the turnbuckle on the
guy to which it is attached until all tension is removed from the tension meter. Do not
tension the guy wire any more than is necessary to remove all tension from the tension
meter. You may then loosen the turnbuckle attached to the tension meter and remove
all tension meter components from the guy wire. Repeat for each guy wire until all tension
meters have been removed.
Piping/Tie-Ins
The following steps are to be completed in conjunction with referencing provided mechanical
drawings for the specific equipment.
1. Attach pilot gas supply piping to the NPT union inlet located on the pilot gas instrument
spool at the base of the flare stack. Pilot fuel supply gas may be propane or natural gas.
a. Propane requirement is 39 Scfh @ 15 psig (approx. 1.0 gal/hour of liquid propane)
b. Natural gas requirement is 65 Scfh @ 15 psig
i. Rates listed above are PER PILOT.
NOTE: Maximum operating pressure of pilot fuel gas supply must not exceed 50 psig.
NOTE: Pilot fuel gas supply must contain less than 5 ppm H2S.
NOTE: Pilot fuel gas supply must have upstream overpressure protection of 400 psig.
NOTE: Temporary gas piping should be protected by site operators from potential of
mechanical damage. Acceptable standards include flagging, cones, protective trays, etc.
2. Attach flare waste gas header piping to one of the flanged 150 # raised-face flare gas
inlet connections located at the base of the stack. Use appropriate gasketing and
hardware for flanges.
NOTE: Temporary gas piping should be protected by site operators from potential of
mechanical damage. Acceptable standards include flagging, cones, protective trays, etc.
3. Attach steam or assist media header piping to the flanged raised-face connection on the
external piping riser attached to the main 24” flare stack body. Use appropriate
gasketing and hardware for flanges.
10
NOTE: Temporary gas piping should be protected by site operators from potential of
mechanical damage. Acceptable standards include flagging, cones, protective trays, etc.
4. It is recommended that some sort of isolation or control valve be installed at least 50
feet away from the system in the flare waste gas header piping. This will allow the
system to be controlled and isolated without requiring personnel to get too close to the
flare in the event of an emergency.
NOTE: Waste gas supply must be isolated and closed before pilot ignition. Flare purge
should be initiated at furthest point from flare system immediately downstream of
waste gas isolation valve.
Control System Set Up and Wiring
The following steps are to be completed in conjunction with referencing provided detailed
electrical schematic drawings for the specific equipment.
1. Customer power service (120VAC/1Ph/60Hz/10A) is to be connected to power supply
terminals located in enclosure on control panel skid.
NOTE: Power supply should be from either UPS or equivalent power source such that
supply cannot be interrupted while flaring.
2. Interconnect wiring must be connected in the field between the local control panel and
the stack-mounted junction box. Ensure that interconnect does not interfere with travel
paths, etc. or is kinked, pinched, flattened, or otherwise visibly damaged.
NOTE: Interconnect should be protected by site operators from mechanical damage.
Acceptable standards include flagging, cones, protective trays, etc.
3. If alarms/remote signals are being used, terminate appropriate facility interconnect
wiring to the applicable terminals.
4. Make required ground connection(s) at grounding lug(s) on both the flare base skid and
any control enclosures. Ensure bare metal/metal contact at all grounding terminations.
Once the above steps are completed, facility technicians should perform loop checks on all
appropriate circuits to ensure continuity and proper operation. The local control panel pilot
switches include a MAN option to enable manual firing of each ignitor. This can be used during
the pre-commissioning phase to verify continuity of the ignition system and proper operation.
Purging Requirements
There is danger of severe explosion in a flare system if the flare pilots are ignited before the
flare has been purged. It is important to purge the entire flare system with a volume of noncondensable gas (typical 5-10 volume changes) to ensure there is no oxygen present in the
system. The flare system includes all piping from relief valves to the riser through the elevation
of the flare at the burning point. Steam should not be used as a purge media.
11
The pilots should be ignited only after the system is thoroughly purged, and as the purge gas is
still being admitted. If the purge gas is combustible, the burning of the purge gas at the flare
will be proof of pilot ignition.
Safe operation of the flare system requires that there be no air, and thus no oxygen, present in
the flared gases as they reach the pilots. The quantity of purge gas is set to avoid entry of air
into the flare system while the flare is in operation and the pilots are burning. Ensure that the
flare system is gas tight prior to purging. Any included liquid seals must be filled with liquid to
the requisite depth prior to purging the flare system. Any manways or inspection openings to
the flare gas line must be blinded. If it is required that the flare system be opened for any
reason, extinguish the pilots before work begins and do not re-ignite them until after the
system has been thoroughly purged. The flare system must be absolutely gas tight before
ignition.
It is recommended that purge flow rate be measured, and appropriate steps taken should a low
flow condition occur during the purging process.
An oxygen-free, clean piping system is ultimately the best practice in any flaring application.
Upon completion of the stack purge, the pilot ignition sequence may be initiated.
System Operation Overview
The flare system and tip configuration is selected by Zeeco considering the various design
parameters discussed with the customer during the inquiry phase. The flare tip and relevant
combustion apparatuses will be selected such that smokeless flaring is achievable across the
designed range of operating conditions (typical); final determination of smokeless flaring needs
will be set by customer through design discussions with Zeeco. In many safety relief scenarios,
it is typical that smokeless flaring requirements do not apply. If you have questions regarding
the selection of the temporary flare system and capabilities, please contact your Zeeco
representative.
Zeeco pilot systems are the leader in industry performance and reliability. The pilots used on
the temporary flare system are the same models and components used in permanent
installations across the world. The pilots are designed to be static mounted at the flare tip for
accurate location to ensure reliable ignition. Zeeco pilot mixers are made from high quality
investment castings and precise machined components to provide reliable performance across
a wide range of operating conditions. Critical pilot components are designed to be retractable
from grade for ease of maintenance and replacement. At the base of the flare stack, the pilot
instrument spool is located for easy operator access. This spool assembly contains the
instrumentation and flow control needed for proper pilot system operation.
Dependent on the needs of the application, assist media may be used in conjunction with the
flare tip design. Using air or steam for assist is typical in most applications. The assist media is
often used to increase turbulence to entrain ambient oxygen into the waste gas to provide
12
more efficient mixing for combustion. Various methods are used for assist control – please
contact your Zeeco representative for more information on using assisted flaring.
Accompanying the flare system is a Zeeco control system with the primary function of
monitoring and controlling the pilots. This system is typically comprised of a local control panel,
stack-mounted junction box, and interconnect wiring. In some cases, additional
instrumentation may be used to satisfy the operational needs of the application.
The below table summarizes critical set points for the temporary flare system detailed in this

Pilot Ignition/System Commissioning
After all appropriate power, wiring, and fuel supply connections have been completed per the
supplied drawings, the pilot system can now be commissioned. Waste flare gas is not required
for commissioning of the pilot system. The pilot system is the critical reliability path of a flare
system so this should be the primary focus of commissioning efforts regardless of waste gas
status. Waste gas can be introduced to the system at any point after the pilot system has been
commissioned, after appropriate purging steps have been completed.
Start-up Sequence
1. Confirm that fuel gas supply is available and plumbed into inlet of pilot gas spool on
flare stack
2. At the flare stack pilot spool, open all isolation valves upstream of the safety shut-off
solenoids
3. Verify that pressure gauges are reading 15 PSIG
a. Regulator adjustment may be necessary after safety shut-off solenoids open
allowing flow during commissioning
4. At the control panel rack, turn the POWER switch to the ON position
5. Turn each PILOT #X switch to the AUTO position
a. PILOT #X FAILURE light will illuminate due to low temperature on pilot
thermocouple(s) – this is ok and expected
b. PILOT GAS LOW PRESSURE light may illuminate momentarily until Low
Pressure Switch (PSL) is proven
i. Refer to 3.a above
13
c. Horn will sound and alarm beacon will illuminate reiterating low pressure
and pilot failure alarms – this is ok and expected
i. Duration is set to 10 seconds; Use ALARM SILENCE pushbutton to
silence horn if needed
6. PSL will confirm fuel gas supply pressure
a. PILOT GAS LOW PRESSURE light will de-energize
7. Safety shut-off solenoids will energize and open
8. Ignitors will begin firing to light pilots
9. Once pilots are ignited, thermocouples will heat up and prove pilots
10. PILOT #X FAILURE light will de-energize as each pilot is proven
a. Respective ignitors will cease firing as each pilot is proven
11. Horn and alarm beacon will de-energize after final pilot is proven
12. System is in steady run state and ready to receive waste gas
Alarm Conditions
• If pilot gas supply pressure drops below 7 PSIG:
o PILOT GAS LOW PRESSURE light will illuminate
o Horn will sound
o Alarm beacon will illuminate
o Alarm signal will be issued out to customer system via dry contacts (if
used)
o NOTE: If fuel gas pressure is lost, subsequent pilot failures will occur
• If pilot flame is lost and thermocouple drops below set point:
o PILOT #X FAILURE light will illuminate
o Horn will sound
o Alarm light will illuminate
o Alarm signal will be issued out to customer system via dry contacts (if
used)
If an alarm condition occurs, the system will automatically begin sparking to attempt to relight
the pilot(s). The system will continue to do so until successful re-ignition or an operator
intervenes to diagnose. Once the pilots are operational, the system is ready to accept waste
gas.
Waste Gas Introduction
Customer is responsible for the appropriate release and flow of waste gas to the flare system in
accordance with facility procedures and design conditions of the flare system.
NOTE: If the flare firing rate is in excess of the designed rate, it is possible to overheat the
surrounding area and cause combustion of nearby materials. To avoid this, we recommend the
installation of an isolation or control valve that can be used to shut the system in if an
emergency occurred (or an alternative acceptable emergency isolation method as approved by
operator).

Operator Training should be completed for each person responsible for the functioning of the flare as
soon as it is ready to be placed into operation. Each shift should be trained similarly. Depending on the
duration of the rental period, a refresher instruction should be conducted once per month (at least) by
plant personnel who are familiar with the system and how to troubleshoot and re-ignite the pilot(s) in
the event of failure and shutdown. ZEECO Service Technicians can be scheduled to perform this training
as well.
