See Page 23
BURNER FLAME
Start the furnace and let it operate about 10 minutes then
look at the burner flame. Flames should be soft and blue,
see Fig. 28. If flames appear abnormal, contact the gas
company or a qualified service technician immediately.
VENTING SYSTEM
Make sure that no parts of the vent air system are blocked
or rusted. Clean or replace before using furnace.
BURNER CLEANING
Check burner. If cleaning is required, contact a qualified
service technician to clean and service burner.
WARNING: Danger of bodily injury or death.
Make sure electric power and gas supply are off before
removing panels or doors, etc.
CLEANING BURNER COMPARTMENT
Because cold air is attracted to the flame during furnace
operation, a build up of lint from bedding and dust, etc.,
in the burner area will occur each heating season. It is
necessary to clean this area regularly. Use a vacuum
cleaner with a narrow attachment to reach small areas.
Be careful in and around the pilot. A change in its
adjustment could be made if struck during cleaning.
WARNING: A BUILDUP OF ANY DUST, LINT
OR FOREIGN MATERIAL IN THE PRIMARY AIR
OPENING OF THE BURNER CAN INTERFERE WITH
THE PROPER AIR GAS MIXTURE AND GAN RESULT
IN A YELLOW FLAME WHICH CAN PRODUCE
CARBON MONOXIDE AND SOOT. THIS CONDITION,
IF ALLOWED TO DEVELOP, CAN LEAD TO BODILY
INJURY INCLUDING DEATH. IT IS IMPERATIVE THAT
THE BURNER(S) BE KEPT GLEAN.
TO REMOVE BURNER(S)
Disconnect gas line inside cabinet.
Refer to "Mounting Your Furnace" section, page 17.
Check the spark gap. It must be carefully adjusted to
specifications, as illustrated Figure 28, for the ignition
device to function properly.

The efficiency rating of these appliances is a product of a thermal efficiency
rating system determined under continuous operating conditions and was
determined independently of any installed system.
**For elevations above 2,000 feet reduce ratings 4% for each 1,000 feet
above sea level.
**BTU/hr. = British Thermal Units per hour.
