FURNACE SHUTDOWN

1.Set the thermostat to the lowest setting. The integrated control will close the gas valve and extinguish flame. Following a 15 second delay, the induced draft blower will be de-energized. After a 100 or 150 second delay period (field selectable), the circulator blower will be de-energized.

2.Remove the burner compartment door and move the furnace gas valve manual control to the OFF position.

3.Close the manual gas shutoff valve external to the furnace.

4.Replace the burner compartment door.

GAS SUPPLY PRESSURE MEASUREMENT

CAUTION

TO PREVENT UNRELIABLE OPERATION OR EQUIPMENT DAMAGE, THE INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES OPERATING.

The line pressure supplied to the gas valve must be within the range specified in the Inlet Gas Supply Pressure table. The supply pressure can be measured at the gas valve inlet pressure tap or at a hose fitting installed in the gas piping drip leg. The supply pres- sure must be measured with the burners operating. To measure the gas supply pressure, use the following procedure.

1.Turn OFF gas to furnace at the manual gas shutoff valve external to the furnace.

2.Connect a calibrated water manometer (or appropriate gas pressure gauge) at either the gas valve inlet pressure tap or the gas piping drip leg. See Honeywell VR9205 gas valve figure or White-Rodgers 36G54 gas valve figure for location of inlet pressure tap.
