NOTE: If pilot does not stay lit, repeat steps 5 through 9; how-
ever, hold the button down for a longer period of time (at least

tempt, the thermocouple should be checked for a possible mal-
function. Call your dealer for service.

the gas valve to the ON position.
11. Replace the access door. (See Fig. 15 or 16.) For down-

12. Turn on the electrical supply to the furnace.
13. Adjust the room thermostat to a setting slightly above room
temperature. This will automatically signal the furnace to
start.
14. Furnace main burners should light shortly after you set the
thermostat. After you verify that the burners are lit, you
may adjust the room thermostat to your own personal com-
fort setting. If the burners fail to light, shut down your fur-
nace and call your dealer for service. Refer to the lighting
instruction label affixed to your furnace blower access door
or page 8 for shutdown procedures.
NOTE: To conserve energy when the heating season has ended,
you should shut down your manually ignited pilot. Follow the
procedures in the “Shutting Down Your Furnace” section of this
manual.
