WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in soot-
ing 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 ever 2,500
hours of operation or every three months. We also
recommend that you keep the burner tube and pilot as-
sembly 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 assembly. 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 Pilot Air Inlet Hole in 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 avail-
able.
