IF FURNACE FAILS TO OPERATE:
Follow this checklist step by step,
advancing to the next step only if fur-
nace fails to start.
• Check thermostat for proper tem-
perature. Is thermostat set above room
temperature?
• Is thermostat set to HEAT?
• Check fuses and circuit breakers. Is
electrical supply on?
• Is manual shutoff valve in gas supply
pipe in open position? (Follow start-up
procedures if you open gas valve.)
NOTE: Turn off electrical supply
before continuing with checklist.
• Is control switch on gas valve in ON
position? (Follow start-up procedures
if you must reset switch to ON posi-
tion.)
• Check manual reset flame rollout
switch located on the burner box in
combustion area. (See Fig. 3 or 4.) If
furnace has experienced high tempera-
ture conditions, this switch will shut
off the furnace. Reset it by pushing the
button on the switch. If it trips again,
shut down the furnace and call for ser-
vice. See “Shutting Down Your Fur-
nace” section in this manual.
• Check for obstructions around the
vent termination outside the structure.
If your furnace still fails to operate, call
your service representative.
For your convenience, record the fur-
nace product and serial numbers on
back page. Should you ever require ser-
vice, you will have ready access to the
information needed by your service
representative.
