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 25).

3.  Blow air through the ports/slots and holes 

in the burner.

4.  Check injector holder located at the end of 

the 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 the primary air holes on the 

injector holder.

6.  In case any large clumps of dust have now 

been pushed into the burner repeat steps 
3 and 4.

Clean pilot assembly also. A yellow tip on the 
pilot flame indicates dust and dirt in the pilot 
assembly. There is a small pilot air inlet hole 
about 2" from where the pilot flame comes out 
of the pilot assembly (see Figure 26). 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.
