BURNER INJECTOR HOLDER AIR INLET HOLE
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 inlet 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
appliance inspected yearly by a qualified service person�
We also recommend that you keep the burner tube 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 damage the pilot
assembly�
1� Shut off unit� Allow unit to cool for at least thirty minutes�
2� Inspect burner, and primary air inlet holes on injector holder for
dust and dirt (see Figure 31).
3� Blow air through the ports/slots and holes in the 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 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� Additional cleaning may be needed
for proper operation based on use/lack of use�
LOGS
• If you remove logs for cleaning, refer to Installing Logs and Volcanic
Stone, Page 11, to properly replace logs�
• Replace log(s) if broken or chipped (dime-sized or larger)�
MAIN BURNER
Periodically inspect all burner flame holes with appliance running� All
slotted burner flame holes should be open with flame present� All round
burner flame holes should be open with a small blue flame present� Some
burner flame holes may become blocked by debris or rust, with no flame
present� If so, turn off appliance and let cool� Remove blockage, blocked
burner flame holes will create soot�
The burner must be replaced prior to the appliance being put into
operation if it is evident that the burner is damaged (use only factory
original replacement burner)�
