PILOT position.
8. Place a lighted match or other suitable source of flame
near the top of the pilot. (See Fig. 13.)
9. Depress the button or knob and hold it down. The pilot
will light. Remove and extinguish the match while contin­
uing to hold the button or knob down for at least 60 sec,
then release. The pilot will remain lit.
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
90 sec). If the pilot flame is extinguished after this second at­
tempt, the thermocouple should be checked for a possible mal­
function. Call your dealer for service.
10. After the pilot flame is established, turn the control knob
on the gas valve to the ON position.

13. Adjust the room thermostat to a setting slightly above
room temperature. This will automatically signal the fur­
nace 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
comfort setting. If the burners fail to light, shut down your
furnace and call your dealer for service. Refer to the light­
ing instruction label affixed to your furnace blower access
door or page 8 for shutdown procedures.
NOTE: lb 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.
SUGGESTION: Setting the thermostat back a few degrees—
and compensating for the difference with warmer clothing—
can make a big difference in your fuel consumption on ex­
tremely cold days. The few degrees at the top of your thermostat
“comfort level” are the most costly degrees to obtain.
