Under some conditions, the fuel or air supply can create a nearly
invisible coating on the flame sensor. This coating acts as an
insulator causing a drop in the flame sense signal. If the flame
sense signal drops too low the furnace will not sense flame and
will lock out. The flame sensor should be carefully cleaned by a
qualified servicer using emery cloth or steel wool. Following
cleaning, the flame sense signal should be as indicated in the
Specifications Sheet.

Periodically during the heating season make a visual check of the
burner flames. Turn the furnace on at the thermostat. Wait a few
minutes, since any dislodged dust will alter the normal flame
appearance. Flames should be stable, quiet, soft and blue with
slightly orange tips. They should not be yellow. They should extend
directly outward from the burner ports without curling downward,
floating or lifting off the ports.
