Your furnace is equipped with a 100% safety pilot that will
shut off the gas supply in case the pilot is not burning
or functioning properly. Make sure the pilot is adjusted
properly and that the pilot generator connection at the
control valve is tight. If the furnace will not stay lit, call your
local gas utility or a qualified service person.
If furnace is equipped with a manual spark igniter, follow
these steps:
1. Review the pilot lighting instructions.

button located on the burner pan for pilot ignition. If
necessary, depress the red button vigorously several
times for pilot ignition.
3. If pilot fails to ignite or a spark is not present while
actuating the red button or by using a match, repeat
steps 5 through 10 listed in "Lighting the Pilot."
