INSPECTING BURNER
Check
pilot
flame pattern and
burner flame pattern often.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot
flame pattern. Figure 22 shows an
incorrect pilot flame pattern. The
incorrect pilot flame is not touching
thermocouple. This will cause the
thermocouple to cool. When the
thermocouple cools, the heater will
shut down. If pilot flame pattern is
incorrect, as shown in Figure 22.
turn heater off (see To Turn
Gas to Appliance on page 11
for non-thermostat models or

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before servicing
CAUTION: You must keep con-
trol areas, burner, and circulating
air
passageways of heater clean.
Inspect these areas of heater be-
fore each use. Have heater in-
spected yearly by a qualified ser-

ODS/PILOT AND BURNER
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 center may carry compressed
air in a can. You can use a vacuum
cleaner in the blow position. If 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 pilot assembly.

Also clean the pilot assembly. A
yellow tip on the pilot flame
cates dust and dirt in the pilot
assembly. There is a 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 compressed air is
not available.
