ODS/PILOT AND BURNER
Use a vacuum cleaner, pres-
surized air.
CLEANING BURNER
PILOT AIR INLET HOLE
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 PSl. Your local computer
store, hardware store. or home cen-
ter may carry compressed air in a
can. You can use a vacuum cleaner
in the blow position. If using com-
pressed 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.
3. Blow air through the ports/slots
and holes in the bumer.
Also clean the pilot assembly. A yellow
tip on the pilot ame indicates dust
and dirt in the pilot assembly. There
is a small pilot air inlet hole about
two inches from where the pilot ame
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.

CABINET
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.
Check pilot flame pattern and
burner ame pattern often.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot
ame pattern. Figure 22 shows an
incorrect pilot ame pattern. The
incorrect pilot ame is not touching
thermocouple. This will cause the
thermocouple to cool. When the
thermocouple cools, the heater will
shut down. If pilot ame pattern is
incorrect, as shown in Figure 22.
