“The Purple People Heater” Patio Plus Radiant Tube Heater is designed for
indoor or outdoor use providing resistance to wind and rain. The slim design and
horizontal or angle mounting option provides versatility to fit almost any patio situation.
The installation of “The Purple People Heater:” must only be performed by a licensed
technician, trained and educated in the installation of this type of gas appliance.
INFRARED HEAT
“The Purple People Heater” heaters are effective in heating outdoor spaces
because they utilize infrared or radiant heat. Infrared energy is the same type of energy
we get from the sun. Infrared energy warms people and objects without heating the
intervening air. Unlike the sun, “The Purple People Heater” does not produce Ultraviolet
(UV) rays than can be harmful. Infrared energy travels by line of sight so the designer
must be aware that doors, panels or windows may obstruct the infrared energy from
reaching the desired location. Overlapping infrared patterns from numerous heaters
may be use effective to provide even heat distribution.
CLEARANCES AND SAFE MOUNTING DISTANCES
“The Purple People Heater” must be installed so that the minimum clearances to
combustibles are maintained. Combustible materials are considered to be wood,
compressed paper, plant fibres, or other materials capable of being ignited and burned.
Such materials shall be considered combustible even though flame proofed, fire
retardant, treated or plastered. Additional clearances may be required for glass, painted
surfaces, plastics, vinyl’s and other materials which may be damaged or melted by
radiant or convections heat.
CLEARANCES TO COMBUSTIBLES
The clearance to combustible materials represents the minimum distance that
must be maintained between the heater and a nearby surface.
The stated clearance to combustibles represents a surface temperature of 90
degree Fahrenheit (32 degrees Celsius) above room temperature. Building material with
a low heat tolerance may be subject to degradation of lower temperatures. It is the
installer’s responsibility to assure that adjacent materials are not subject to degradation.
A warning statement that an overhead heater is present should be installed so
that the minimum clearances marked on the heater will be maintained from vehicles
parked below the heater.
Minimum clearances (inches) from combustibles measured from radiant surface.
Clearances are reduced by 1/3, 15 ft (4.6 meters) from the burner.
For installation at elevations above 2000 ft (610m), the appliance shall be de-rated 4
percent for each 1000 ft (305m) of elevation above sea level.

ELECTRICAL SPECIFICATIONS
Electrical
120VAC / 60 Hz / 1-Ph / 1A
In locations used for storage of combustible materials, signs must be posted to specify
the maximum permissible stacking height to maintain the required clearances from the
heaters to combustibles. Signs must either be posted adjacent to the heater thermostats
or in the absence of such thermostats in a conspicuous location.
Starting current 3 Amp. Running current 1 Amp.
Ignition System:
120 Volt / Hot surface igniter
For thermostat control:
All heaters are designed for compatibility with either 120 Volt thermostat
controllers or 24 Volt thermostat controllers. For use with 120 Volt controllers, the
heater must be plugged into a “switched” 120 Volt duplex receptacle, where the
receptacle is switched by the thermostat controller. Heating zones may be established
where one 120 Volt thermostat, controls more than one heater, provided the total heater
electrical load does not exceed the maximum allowable amperage on the circuit.
For 24 volt thermostat control plug the heater into a 120 Volt duplex receptacle.
Remove the jumper wire on the control box marked “24 Volt thermostat” and connect
the thermostat wire to the terminals. Ensure that if the thermostat has a heat
anticipator, that the heat anticipator is set at maximum. When using a 24 Volt
thermostat, only one heater may be controlled by one thermostat.
Heaters must be electrically grounded in accordance with the National
Electrical Code, ANSI\NFPA 70 or the current Canadian Electrical Code,
CSA C22.1. Polarity of Line voltage and neutral wires must be
maintained. The total load of all heaters in a circuit must be considered
for overload control of that circuit. See electrical specifications above.

SUSPENDING THE SYSTEM
WARNING
Inadequate or improper suspension of the tube heater can result in collapse of
the system, property damage, and personal injury or death. It is the installer’s
responsibility to ensure that the hardware and structural supports from which the heater
is suspended are sound and of adequate strength to support the weight and expansion
forces of the heater.
Consider that the heater will expand in length as much as ½ inch (12.5mm) or
more for every 10 ft (3 m) of system length. Typically, the greater the firing rate, the
greater the expansion.
Survey the available structural supports, considering the system configuration
and heat requirements of the area to establish the optimum heater location. Locating a
heater directly under joists or beams, or installing supplemental steel support rail or
angle iron can substantially reduce labour and materials. Hardware with a minimum 40
lbs workload must be used at each heater suspension point. Connect the structure
using typical hardware as illustrated below or by other mechanically sound means.
GAS PIPING
1. All gas piping and connections shall be made in accordance with local codes and
CAN/CGA B-149 or ANSI standard Z223.1.
2. Connect the burner to gas supply with flexible gas connector.
3. A drip leg must be installed in the gas line at the heater inlet connection tee
followed by a pipe drop to the heater. Failure to provide a drip leg could result in
condensation and foreign matter passing into the gas valve. Failure to install a
drip leg in the gas line can cause property damage, injury or death and will void
the heater warranty.
CAUTION: Correct inlet pressure is vital to efficient operation of heaters. Refer to the
rating plate and, if necessary, consult Gas Company.
WARNING
Never use a match or other flame to test for gas leaks. Use soap and water solution
to check for leaks to all connections and joints and if bubbles appear, leaks have
been detected and must be corrected. Never operate the heater with leaking
connections. The supply system should be checked first with heater turned off
followed by another check with the heater on. The supply gas pressure must be
checked with all heaters in operation.
GAS SUPPLY, HEATER EXPANSION, AND FLEXIBLE GAS CONNECTION
The gas supply must be installed to the heater using:
In USA an approved Stainless Steel Flexible Gas Connector certified for use on an
infrared radiant tube heater (ANSI Z21.24 CSA 6.10)
In Canada an approved Type 1 Hose Gas Connector (CAN/CGA 8.1)
The heater must be isolated from the gas supply piping system by closing its
individual manual shut off valve (field supplied) during any pressure testing of the
gas supply piping system.
Compensation for normal gas supply pipe expansion, and radiant tube heater
expansion must be provided. All piping must conform to local codes.
Provide a 1/8 in (3.2mm) NPT plugged tapping, accessible for test gauge
connection, immediately upstream of the gas supply connection to the heater.
Test for leaks. All gas piping and connections must be tested for leaks after the
installation is completed.
Apply soapsuds solution to all connections and joints and if bubbles appear,
leaks have been detected and must be corrected. Do not use a match or open flame
of any kind to test for leaks. Never operate the heater with leaking connections.
The supply systems should be checked first with the heater turned off followed by
another check with the heater turned on. The supply gas pressure must be checked
with all heaters in operation.
A drip leg must be installed in the gas line at the heater inlet connection tee
followed by a pipe drop to the heater. Failure to provide a drip leg could result in
condensation and foreign matter passing into the gas valve. Failure to install a drip
leg in the gas line can cause property damage, injury or death and will void the
heater warranty.

products warranty. Process application requires field inspection and/or certification by
local authorities having jurisdiction.
IMPORTANT
Single or multiple heater placement must be such that continuous operation of
heater(s) will not cause combustible material or materials in storage to reach a
temperature in excess of ambient temperature plus 90 degrees Fahrenheit (50 degrees
Celsius).
It is the installer’s responsibility to ensure that building materials with a low heat
tolerance, which may degrade at lower temperatures, are protected to prevent
degradation. Refer to Clearance to Combustibles information in these installation
instructions.
INDOOR PRE-INSTALLATION SURVEY
It is recommended that a full heating design, including a heat loss calculation be
conducted. Heater sizing and placements must consider available mounting height,
sources of heat loss, and clearances to combustibles with respect to stored material,
moveable objects (cranes, vehicles, lifts, overhead doors, etc) sprinkler systems, and
other obstructions on the site. Consideration must also be given to vent / duct
placement and the allowable combined lengths of vent and duct.
1 Carefully survey the area to be heated and place the burner and combustion
chamber in the coldest area if possible.
2. The heater shall be hung in such a fashion so as to conform with the clearances
to combustibles described on the nameplate.
3. Clearances to combustibles must be maintained from vehicles parked below.

gas connector or the rigid piping.
WARNING
This heater is equipped with an automatic ignition system.
There is no pilot. No person shall attempt to light the heater by hand.
Serious injury, property damage or death may occur.
PATIO HEATING DESIGN CONSIDERATIONS
“The Purple People Heater” placement is critical for effective and efficient patio
heating.
For multiple heaters, if heaters are placed too close together, or mounted too
low, patrons of the patio may be uncomfortable. If heaters are placed too far apart, or
too high, on a breezy or wind-swept patio, the area may never become comfortable.
Infrared heaters work best if placed in areas of greatest heat loss, such as the
open side of a semi-protected patio.
“The Purple People Heater” may be angled mounted from 0 to 45 degrees
maximum.
Windy conditions can be a problem when heating any patio. Windbreaks can be
extremely effective in increasing comfort levels.
The heating requirements of any patio depend greatly on local climatic
conditions. It is recommended that you work with a local, and experienced supplier and
installer who are familiar with the heating requirements in your area.
For outdoor applications, the rigid pipe mount system is recommended to avoid
damaging movement under various weather conditions. The chain mount is ideal for
indoor use when hanging from an overhead structure.
OUTDOOR PIPE-MOUNT INSTALLATION
1. Install post mounting brackets to post, unistrut or structure, ensuring it will maintain
a stable and a safe environment.
2. Attach wire hanger and support bracket assemblies to end of post mounting brackets
or unistrut mounting bracket. The first hanger must be no more than 6 inches from
the flange.
(See diagrams PTH-B burner end pipe mounting bracket assembly, PTH-J tube
joint pipe mounting bracket assembly and PTH-V vent end pipe mounting bracket
assembly).

WARNING
To allow heater expansion the gas supply must be installed using:
In the USA: a stainless steel flexible gas connector certified for use on an
infrared radiant tube heater (ANZI Z21.24 CSA 6.10)
In Canada: a Type 1 hose connector (CAN/CGA 8.1). Also the flue vent, and
combustion air intake (if used) must be installed in such a manner that the normal
expansion of the heater will be accommodated.
WARNING
This heater will expand in length as it heats up. It is a normal condition that
during heat-up and cool-down a tube heater will expand and contract. Allowances for
heater expansion must be made in the gas connection, venting and combustion air
ducting. Improper installation, alteration, or adjustment can result in property
damage, injury or death.
The BTU input and the tube length determine the overall expansion that occurs.
A typical infrared tube installation will expand toward both the burner and the vent
end.

INDOOR INSTALLATIONS, VENTING OF PRODUCTS OF COMBUSTION
1. The tube system has been approved for vented and unvented applications. When
installed unvented indoors, it must be electrically interlocked to an exhaust fan with
an air proving switch. The exhaust fan must provide exhaust in the amount of 300
c.f.m. for every 100,000 BTU of input. When installed unvented provision must be
made to supply adequate combustion air from outside the space. Combustion air
openings must be in the amount of one square inch or more of free area for each
10,000 BTU.
When installed vented, installations must comply with all applicable codes.
When installed in an adequately ventilated agricultural building used only for
brooding purposes, the heater may be installed unvented and discharge the
products directly into the space without interlocking provided the maximum input
does not exceed 20 BTU per cubic foot, or the input specified by local codes. There
must be ventilation during the heating cycle.
2. All vent material shall meet C.G.A. approval standards and be a minimum of 4”
diameter.
3. The maximum allowable length of vent pipe is 60 ft. This length includes the
combination of inlet air vent for combustion and exhaust venting. The RADIANT
TUBE IS NOT INCLUDED IN THIS MEASUREMENT. For every 90-degree bend in
the system, 5 ft. must be deducted from the allowable total.
4. When venting through a combustible wall or roof type “B” vent must be used for that
portion of the vent that passes through the wall or roof. FOR WALL VENTING THE
MANUFACTURER’S APPROVED VENT TERMINAL MUST BE USED. THE USE
OF ANY WALL VENT TERMINAL OTHER THAN THAT SUPPLIED BY THE
MANUFACTURER WILL VOID WARRANTIES. THE MANUFACTURER ACCEPTS
NO RESPONSIBILITY FOR DAMAGES CREATED BY USING OTHER VENT
TERMINALS.
5. All vent pipe used with a slip fit connection must be mechanically secured and all
vents must be supported every 3 ft.
6. Vent pipe of single wall construction shall not run through unheated spaces unless
insulated.
7. All vent pipes longer than 10 ft. must be insulated or have insulated type vent
material.
8. Vents for products of combustion shall not terminate less than 3 ft. from a
combustion air inlet of any other appliance, less than 3 ft. from a building opening or
be directly above a gas utility meter or service regulator. On “U” model heaters the
vent terminal shall not be closer than 4 inches from the combustion air inlet.
9. Vent terminals shall not be located less than 3 ft. above grade.
10. Horizontal vent systems shall slope downwards not less than ¼ inch per foot from
the start of the vent system to the vent terminal.
11. When installed in a large and adequately ventilated space (agricultural building used
only for brooding purposes) the heater may be installed un-vented without
interlocking, and may be operated by discharging the combustion products directly
into the space, subject to the approval of the authority having jurisdiction and
provided that the maximum input of the appliance does not exceed 20 BTUH/ft3 (0.2
kW/m3) of the space in which the heater is located. An appliance designed to
produce a controlled atmosphere need not be subject to these conditions.
WARNING
This heater will expand in length as it heats up. It is a normal condition that
during heat-up and cool-down a tube heater will expand and contract. Allowances for
heater expansion must be made in the gas connection, venting and combustion air
ducting. Improper installation, alteration, or adjustment can result in property
damage, injury or death.

Installation of a gas fired tube heater must conform to all heating installation
design procedures including clearance to combustibles, connection to the gas and
electrical supplies, and ventilation.
This heater is not for installation in a Class 1 or Class 2 explosive environment,
nor a residence. If installation of this equipment is in question, consult with local
authorities having jurisdiction (Fire Marshall, labour department, insurance underwriter,
or others).
Revisions to codes and/or standards may require revision to equipment and
installation procedures. In case of discrepancy, the latest codes, standards, and
installation manual will take priority over prior releases.
WARNING
Where there is the possibility of exposure to combustible airborne materials or
vapour, consult the local fire inspector's office, the fire insurance carrier or other
applicable authorities for approval of the proposed installation.
Do not use in an atmosphere containing halogenated hydrocarbons or other
corrosive chemicals. Some compounds in the environment can cause an accelerated
rate of corrosion to the heat exchanger.
The heater manufacturer cannot anticipate all types and chemical composition of
possible contaminants at project sites. Confer with project site safety, health and
engineering staff and/or local authorities having jurisdiction such as the Fire Marshall
and Department of Labour for possible contaminants and any conflict with the
installation of hot surface heating equipment.
WARNING
HEATER EXPANSION
It is normal condition that during heat-up and cool-down a tube heater will
expand and contract. Allowances for heater expansion must be made in the gas
connection, venting and combustion air ducting.
WARNING
GAS CONNECTION
Improper installation, connection, or adjustment can result in property damages,
toxic gases, asphyxiation, injury and death. Using an approved flexible gas connector in
the USA and Rubber Type 1 hose connector in Canada, the gas supply to the heater
must be connected and tested in accordance with all local, state, provincial, and
national codes (ANSI Z223.1/NFPA 54 in USA: B149.1 in Canada) and as indicated in
the manual.
WARNING
VENTING
Inadequate venting of a heater may result in asphyxiation, carbon monoxide
poisoning, injury or death. The heater may be directly or indirectly vented from the
space. Venting must be in accordance with all local, state, provincial, and national
codes (ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada) and as indicated in this
manual.
WARNING
START-UP SMOKE CONDITION
During start up, the heating of material coatings used in the production process
of tubes and reflectors will create smoke during the initial period of operation. This
condition is normal and temporary. Ensure that there is sufficient ventilation to
adequately clear any smoke from the space. Notify site and safety personnel to ensure
that alarm systems are not unduly activated.
WARNING
CLEARANCES TO COMBUSTIBLES
Location of flammable or explosive objects, liquids or vapours close to the
appliance may cause fire or explosion and result in property damage, injury or death.
Do not use, store or locate flammable or explosive objects, liquids or vapours in
proximity of the appliance.
The clearance to combustible material represents the minimum distance that
must be maintained between the outer heater surface and a nearby surface. The stated
clearance to combustible represents a surface temperature of 90 F (50 C) above room
temperature. It is the installer's responsibility to ensure that building materials with a low
heat tolerance, which may degrade at lower temperatures, are protected to prevent
degradation.
Minimum 24” must be provided at the centre of the appliance for burner
servicing. When venting through a wall the vent terminal must be located at least 7.0 ft
above grade. This appliance must be mounted at least 7 ft above the floor in Canada,
and 8 ft above the floor in the U.S.
Anyone in the proximity of the appliance should be alerted to the hazards of high
surface temperatures and should stay away to avoid burns or clothing ignition. Clothing
or other flammable materials should not be hung from the appliance, or placed on or
near the heater.
Any cover removed from the appliance must be replaced prior to operation of the
heater.
Do not use this appliance if any part has been under water. Immediately call a
qualified service technician to inspect the appliance and to replace any part of the
control system and any gas control, which has been under water.
