– Read and Save These Instructions –
This appliance is equipped with a Blocked-Flue shutoff device. If any part of the flue-
gas passageway in the combustion chamber, exhaust pipe or rain cap should become
blocked or adversely restricted, a pressure sensing switch (Fig.27 pg.11) will break the
electrical control circuit and not allow the burner to run. There is a "Manual Reset"
button on this switch that will have to be reset before re-firing can occur. If the burner
fails to start after resetting once, call a qualified service technician to clean the flue
passageways and/or replace the switch. Cleaning instructions can be found in Section
(6.1 G) of the Maintenance section of this manual.
