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 pressure 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 fl ame indicates dust and dirt in
the pilot assembly. To clean the pilot assembly fi nd the
small pilot air inlet hole about two inches from where
the pilot fl ame comes out of the pilot assembly (see
fi gure 18). 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.
