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 qualifi ed service person. Heater 
may need more frequent cleaning due to excess lint 
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 
sooting 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.

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 16). 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.
