Table 6 – Single--Stage Sequence of Operations

Trial--for--Ignition Sequence: The ignition sequence is to immediately energize the inducer motor on a call for heat. Within approximately 5
sec of the call for heat, the gas valve will open and the igniter will spark. Seven sec will be allowed to prove flame sense on the far burner.

Flame--Proving: Once flame is proven, the control will wait an additional 45 sec to energize the indoor blower motor. On removal of the call
for heat, the gas valve will immediately shut down, the inducer motor will run for an additional 5 sec, and the indoor blower will run for an

additional 45 sec (minimum).
