Care And Maintenance - Procom MN100HBG Owner's Operation And Installation Manual

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
each use. Have heater inspected yearly by a qualified service techni-
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.
Periodically inspect main burner with the heater running. Debris or rust can cause blockages.
If present, turn off the heater and let it cool, and remove blockage. Blockages will create soot.
BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit ev-
ery 2,500 hours of operation or every three
months. 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 us-
ing compressed air in a can, please follow
the directions on the can. If you don't follow
Use a vacuum cleaner, pressurized air, or a
small, soft bristled brush to clean.
A yellow tip on the pilot flame indicates dust
and dirt in the pilot assembly. There is a small
pilot air inlet hole about 2" from where the
pilot flame comes out of the pilot assembly
(see Figure 25). With the unit off, lightly blow
air through the air inlet hole. You may blow
through a drinking straw if compressed air is
not available.
Air Passageways
Use a vacuum cleaner or pressurized air to
clean.
Exterior
• Use a soft cloth dampened with a mild soap
and water mixture.
• Wipe the cabinet to remove dust.
