INSPECTING BURNER
Check pilot ame pattern and burner ame pattern
often.
PILOT FLAME PATTERN
Figure 21 show a correct pilot ame pattern. Figure 22
shows an incorrect pilot ame pattern. The incorrect
pilot ame pattern is not touching thermocouple. This
will cause the thermocouple to cool. When the thermo-
couple cools, the heater will shut down. If pilot ame
pattern is incorrect, as shown in Figure 22:
• Turn heater off (see To Turn OFF Gas to Appli-
ance, page 10.
• See Troubleshooting, pages 12-13.
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 qualied service person. Heater
may need more frequent cleaning due to excess lent
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 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 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 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.
Figure 17
Note: Your heater may have either pilot assembly.
3. Blow air through the port/slots and holes in the
burner.
A yellow tip on the pilot ame indicates dust and dirt in
the pilot assembly. To clean the pilot assembly nd the
small pilot air inlet hole about two inches from where
the pilot ame comes out of the pilot assembly (see
gure 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.
