CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before
servicing.
CAUTION: You must keep control areas, burner and
circulation air passageways of heater clean. Inspect
these areas of heater before use. Have the heater
inspected yearly by a qualified service person. Heater
may need more frequent cleaning due to excess lint
from carpeting, bedding material, pet hair, etc.
Make sure grille guard is in place before running heater.
If screen or grille guard is removed for servicing it must
be replaced prior to operating the heater.
WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in
sooting and property damage.
CLEANING ODS/PILOT AND BURNER
• Use as vacuum cleaner, pressurized air or
small soft bristled brush to clean.
CLEANING BURNER PILOT AIR HOLE INLET
We recommend that you clean the unit every 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 psig.
This can be done by using a vacuum cleaner in the blow
position, 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 burner or pilot assem-
bly. In addition, the directions that follow should also be
followed.
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.
3. Blow air through the port/slots and holes in the
burner.
A yellow tip on the pilot flame indicates dust and dirt in
the pilot assembly. To clean the pilot assembly find the
small pilot air inlet hole about two inches 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 com-
pressed air is not available.
