Ignition Sources
• There are 3 different ways a burner can be ignited:
- 1) Standing Pilot Ignition
- 2) Intermittent Pilot Ignition
 Intermittent Pilot - S8610U
- 3) Direct Burner Ignition
 Hot Surface Ignition – S8910U
 Direct Spark Ignition – S87

Universal Intermittent Pilot Module
• What is the S8610U3009?
- Provides electronic control of
-
intermittent pilot ignition systems
used on gas fired furnaces,
boilers, and other heating
appliances
It’s the brain of the ignition
system
 Receives call for heat signal from the


thermostat
Starts the spark ignition
Opens the pilot valve
Senses to see if the pilot is lit
Opens the main burner
Shuts things down at the end of the
call for heat
Monitors damper as opened or closed,
if damper is attached

The Benefits
8
• Feature
• Benefit
• Field selectable operating
sequence can be
customized
• Allows for more options in the field:
- 0 or 30 second prepurge and
- 15 or 90 second trial for ignition
• Control locks tothselected
sequence on 20 “call for
heat”
• Assures selected sequence is retained
permanently
• LED communicates
system status
• Green LED indicates status, error
codes and pilot flame strength
• Integral damper connector
• If senses use with a vent damper it
locks the control, so damper must be
used
• Continuous retry ignition
sequence
• Provides 100% shutoff for both Natural
and LP applications
Additional benefits
• Feature
• Benefit
• Single-rod or dual-rod flame
sensor
• Works in more applications
• Terminal-to-terminal wiring
instructions
• Flame sense terminal 3/16” male
QC (virtually all 2-rod systems
sold have the sense terminal as
3/16” QC)
• Spark cable adapter
• 2.0 A main valve load rating
9
• Reduces wiring errors
• Prevents possible mis-wire of
spark sense and potential for
abnormal appliance light-off
• Includes adapter for rajah and nail
type cable on existing systems;
Simplified use
• Broader application; Fits more
jobs

Installation
Installation of the S8610U
•
Mount new ignition module
- Do not mount with terminals facing up
- protect the module from exposure to water, moisture, corrosive
chemicals and excessive dust and grease.
•
Wire the module
- Wire the module per the installation instructions
- Verify the thermostat anticipator setting

Wiring continued
For systems with a
vent damper
connect the
damper to P1
Once the vent damper
connection is made, the
control must be used with a
vent damper.
