Under some conditions, the fuel or air supply can create a
nearly invisible coating on the ame sensor. This coating
acts as an insulator causing a drop in the ame sense
signal. If the ame sense signal drops too low the furnace
will not sense ame and will lock out. The ame sensor
should be carefully cleaned by a qualied servicer using
emery cloth or steel wool. Following cleaning, the ame
sense signal should be as indicated in the Specications
Sheet.
The heat exchanger ue passageways should be
inspected at the beginning of each heating season.
