initial power-up. Once this fuse has blown, the module does not
work unless the vent damper is connected.
To connect the plug-in vent damper:
Remove and discard the vent damper plug from the
module terminal strip.
Using the wiring harness supplied, insert the matching
pin plug into the receptacle on the module and the
other end to the vent damper.
To connect the D80B Vent Damper, follow the wiring
diagrams supplied with the vent damper.
Connect S8610 Module
Connect the gas control and other remaining system
components to the ignition module terminals as shown
in Fig. 14 through 16:
• Fig. 14 shows a basic circuit for a heating only
atmospheric burner system.
• Fig. 15 shows a heating only atmospheric burner
system with a D80D Vent Damper.
• Fig. 16 shows a heating only system with a D80B
Vent Damper.

Adjust the thermostat heat anticipator to match the
system current draw. The current draw equals the total
current required for the ignition module (0.2A) plus the
gas control and any other auxiliary equipment in the
control circuit.
Connect Ground Control System
The igniter, flame sensor, and ignition module must share a
common ground with the main burner.
Connect the ground wire with the female 1/4 in. quick-
connect terminal to the male quick-connect GND
(BURNER) terminal on the ignition module.
Strip the other end of the wire and fasten it under the
igniter bracket mounting screw. If necessary, use a
shield to protect the ground wire from radiant heat.
The burner serves as the common grounding area. If
there is not a good metal-to-metal contact between
burner and ground, run a lead from the burner to ground.
NOTE: Earth ground is not required.
