1. Ground yourself properly before installing the new ICM2813
control board.
2. Mount the new control using any screws and fasteners
previously removed.
3. Connect all line/low voltage, accessory, thermostat and
ground wires.
4. Verify the sequence of operation.
NOTE: The wire from the door switch to Line VAC input
can extend the wire or use the blue wire in kit.
* The heating and cooling OFF delay depends on the option
chosen by the jumper position. The default settings for the
heating and cooling OFF delays are 90 seconds and 45 seconds
respectively.

Upon a call for heat, the thermostat will energize the W terminal
with 24 VAC. With the heat call in place, the inducer fan and
safety switch. The control will enter a 15 second inducer pre
completion of the 15 second inducer pre-purge, the hot surface
igniter is energized. There is a 20 second igniter warm up period
before energizing the gas valve. Once the gas valve is energized,
gas flows into the burners where it is ignited by the hot surface
igniter. Once the burners are on, the flame is sensed by a flame
for ignition period where the control checks the flame signal and
proves the flame. Once flame is established, there will be a 45
second heat ON delay before energizing the main blower. When
the call for heat ends, the gas valve is de-energized, burners go
post purge to purge any residual exhaust gases from the system.

to purge the residual cool air from the duct work. At the end of the
