The primary air inlet holes allow the proper 

amount of air to mix with the gas. This provides 

a clean burning flame. Keep these holes clear 

of dust, dirt, lint and pet hair. Clean these air in-

let holes prior to each heating season. Blocked 

air holes will create soot. We recommend that 

you clean the unit every three months during 

operation and have heater inspected yearly by 

a qualified service person.
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 PSI. 

Your local computer store, hardware store or 

home center may carry compressed air in a 

can. 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 dam-

age the pilot assembly.
1.  Shut off unit, including pilot. Allow unit to 

cool for at least thirty minutes.

2.  Inspect burner, pilot and primary air inlet 

holes on injector holder for dust and dirt 

(see Figure 45).

3.  Blow air through the ports/slots and holes 

in burner.

4.  Check injector holder located at end of 

burner tube again. Remove any large 

particles of dust, dirt, lint or pet hair with 

a soft cloth or vacuum cleaner nozzle.

5.  Blow air into primary air holes on injector 

holder.

6.  In case any large clumps of dust have now 

been pushed into burner repeat steps 3 

and 4.

Clean pilot assembly also. A yellow tip on pilot 

flame indicates dust and dirt in pilot assembly. 

There is a small pilot air inlet hole about two 

inches from where pilot flame comes out of 

pilot assembly (see Figure 46). With unit off, 

lightly blow air through air inlet hole. You may 

blow through a drinking straw if compressed 

air is not available.
