Cleaning
Heat Exchanger Tubes – Your Pellet Stove Room Heater is designed with a built in heat exchanger tube cleaner.
This should be used every 2 or 3 days to remove ash build up on the heat exchanger tubes, which can reduce heat
transfer. The handle, for the heat exchanger tube cleaner, is located in front of the vent tubes on front side of
heater. Slide the rod front to back several times to clean the tubes then follow the instructions for ash removal.
Fans – DANGER: RISK OF ELECTRIC SHOCK. DISCONNECT POWER BEFORE SERVICING UNIT
Over time ash or dust may accumulate on the blades of the circulation & exhaust fans. The fans should be
inspected, periodically, and if any accumulation is present vacuumed clean as the ash or dust can impede the fans
performance. It is also possible that creosote may accumulate in the exhaust fan therefore, this must be brushed
clean.
The exhaust fan can be found behind the left side panel (facing the front of the heater), the circulation fan can be
found behind the right side panel. To access the igniter, remove the air inlet tube and cover (2 screws) (Figure 27).
Note: When cleaning, take care not to damage the fan blades.
