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

Installation and Set Up
Installation of the S8910U
•
Mount the module
-
•
Do not mount with terminals facing up
protect the module from exposure to water, moisture, corrosive
chemicals and excessive dust and grease.
Install selection tab (“personality plug-ins”)
-
The number of trials for ignition and trial time is determined by the
selection tabs.
 Four selection tabs are included with the S8910U. (A,B,C,D)
 Without a selection tab, the module operates at four-second trial
time and one ignition.
•
•
•
Selection tabs A and B — 4 seconds.
Selection tabs C and D — 7 seconds.
Wire the module
- Use diagrams in installation instructions for wiring
10
Selection Tab Installation
See Tables 1 through 3 in installation instructions (Form 68-1061) for correct
tab selection.
Select and Install the correct tab, push firmly in place and discard the
remaining tabs.

Troubleshooting of the S8910U
LED shows system status for the current call for
heat:
- Pulsing heartbeat is the normal operating mode during a call for heat (24V
-
terminal is powered). The system can be in any of the normal operating modes
including prepurge, warm-up, ignition trial, between trial purge, or normal run.
One flash indicates the S8910U is in an ignition lockout mode. The most
probable cause is the main burner failing to light or failure to detect the flame.
Run the appliance through a call for heat and if the burner does not light, check
the:
 gas supply
 input voltage
 hot surface igniter
 gas control
 Wiring
- If the main burner lights, but goes out at the end of ignition trial, check the:
 igniter/sensor
 flame rod
 burner ground connections
 wiring
16
Troubleshooting of the S8910U
LED – Continued
• Two flashes indicates the flame rectification signal is weak. The most probable
causes are:
- contaminated or mis-located igniter/sensor or flame rod
- poor flame sense lead-wire insulation or connections
- poor gas pressure
• If the flame rectification signal is strong when the appliance lights, but weak
while heat is being delivered, check for overheating of the igniter/sensor,
flame rod ceramic or flame sense leadwires.
• Three flashes indicate an internal error. The most probable cause is an S8910U
logic failure. Start a new call for heat and if the three-flash signal returns, replace
the S8910U.

The S8910U Advantage
• When promoting the S8910U keep these advantages in mind:
 The S8910U replaces over 100 Honeywell and competitor’s ignition
modules; reduces inventory by stocking one versus many and saves
time and money looking for the right part.
 Easy to use instructions and adaptation accessories saves the
contractor valuable time and resources.
 Personality” Plug-Ins - match the ignition sequence of the model being
replaced using the plug in selector tabs for a true Universal replacement.
 The S8910 is application flexible and can be used with single rod or dual
rod systems, and natural or LP gas.
 The diagnostic LED makes troubleshooting simple, identifying ignition
lockout, flame rectification signal and control failure, solving the
problem quickly and satisfying the customer.
