CARE AND MAINTENANCE
WARNING: Turn off heater and let cool before servicing.
CAUTION: You must keep control areas, burner, and circulating
air passageways of heater clean. Inspect these areas of heater before
-
cian. Heater may need more frequent cleaning due to excessive lint
from carpeting, bedding material, pet hair, etc.
WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and property damage.
The primary air inlet hole allows the proper
amount of air to mix with the gas. This pro-
clear of dust, dirt and lint. Clean this air inlet
hole prior to each heating season. A blocked
air hole will create soot. We recommend that
you clean the unit every three months during
operation and have heater inspected yearly
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend
using compressed air no greater than 30 PSl.
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 compressed air in a
can, please follow the directions on the can.
If you don’t 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 burner and pilot for dust and dirt.
