5.The draft fan will operate. After an adequate purge time, the electric spark igniter will light the burners.

6.The burners will extinguish and relight automatically upon the demand of the room thermostat.

VENT SAFETY SYSTEM:

This gas furnace is equipped with a manual reset high tem- perature sensor or rollout switch which in the unlikely event of a sustained main burner flame rollout will shut off the flow of gas by closing the main gas valve. The ignition modules will also be disabled, preventing the flow of gas to the valve. The switch is located inside the gas heat access panel above the burner inlet. Flame rollout can be caused by blockage of the power vent system, improper gas pressure or adjustment. If this event occurs the furnace will not operate properly. The gas supply to the furnace should be shut off and no attempt should be made to place the furnace in operation. The sys- tem should be inspected by a qualified service technician. Refer to Figure 2 for a typical installation.

100% SHUT OFF:

The ignition modules are designed for 100% shut-off. If the furnace fails to ignite after three ignition attempts, the flow of gas will be shut off and the ignition module will lock out. The module can be reset by:

A.Turning the system switch on the room thermostat to the “OFF” position and back to the “HEAT” position.

B.Decreasing the set point of the room thermostat below the temperature in the conditioned space and returning it to its original setting.

FIGURE 2- TYPICAL INSTALLATION

If the furnace continues to lock out, a qualified service techni- cian should be called to determine the cause of the problem.
