CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit every 2,500 hours of operation or every three months.
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 heater inspected yearly by a qualified electricion.
We recommend you keep the burner 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. You
can use a vacuum cleaner in the blow position. 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 the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

Primary Air Inlet
2. Inspect burner, pilot and primary air inlet holes on injector holder for dust and dirt (see Figure 30).
3. Blow air through the ports/slots and holes in the burner.
4. Check the 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.
