CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burners, and
circulating air passageways
of heater clean. Inspect these
areas of heater before each use.
Have heater inspected yearly
by a qualified service person.
Heater may need more frequent
cleaning due to excessive lint
from carpeting, pet hair, bedding
material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
BURNER INJECTOR HOLDERS AND
PILOT AIR INLET HOLES
The primary air inlet holes allow the proper amount
of air to mix with the gas. This provides a clean
burning flame. Keep these holes clear of dust, dirt,
lint, and pet hair. Clean these air inlet holes prior to
each heating season. Blocked air holes will create
soot. We recommend that you clean the unit every
three months during operation and have heater
inspected yearly by a qualified service person.
We also recommend that you keep the burner
tubes and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store, or home center
may carry compressed air in a can. You can use a
vacuum cleaner in the blow position. If using com
-
pressed air in a can, please follow the directions on
the can. If you donʼt follow directions on the can,
you could damage the pilot assembly.
1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burners, pilot, and primary air inlet
holes on injector holder for dust and dirt (see
Figures 45 and 46, page 26).
