Routine Cleaning and Maintenance
The following list of components should be inspected and maintained routinely to ensure that the
appliance is operating at its’ optimum and giving you excellent heat value:
Burn Pot Liner
Ignitor Tube
Air Intake Tube
Burn Pot
BURNER POT AND LINER (2-3 days)
Every two to three days (when the unit is cold), remove the burn-pot liner from the stove. Using a
metal scraper, remove material that has accumulated or is clogging the liner’s holes. Then dispose of
the scraped ashes from the liner and from inside the burn-pot. Place the burn-pot back into the stove,
making sure that the pipes are properly inserted into the burn pot. Place the liner back into the burn-pot,
making sure that the ignitor hole in the liner is aligned with the ignitor tube. Pushing the liner up against
the ignitor tube.
If, after long periods of burning, the fire continually builds up and overflows the burn pot or there is a
build up of clinkers, this is an indication that the pellet fuel quality is poor, the stove may need cleaning,
or the air adjusted. Check the stove for ash build up (clean if required) and adjust the slider / damper
to produce the proper clean combustion.
To clean the burn pot swing the door open. Pull the burn pot clean-out lever in and out several times; the
lever is located under the door opening (shown in Figure 6). Ensure the lever is pushed in before closing
the door.
HEAT EXCHANGER TUBES (2-3 days)
A handle is located in the center of the stove just above the door (shown in Figure 6). This handle is to be
pulled up and down a few times (ONLY WHEN THE UNIT IS COLD) in order to clean away any fly ash that
may have collected on the heat exchanger tubes. As different types of pellets produce different amounts
of ash, cleaning of the tubes should be done on a regular basis to enable the unit to run efficiently.
ASH PAN AND DOOR GASKETS (weekly)
After extended use the gasketing may come loose. To repair this, glue the gasketing on using high-
temperature fiberglass gasket glue available from your local dealer. This is important to maintain an
airtight assembly.
DOOR GLASS CLEANING (2-3 days)
Cleaning of the glass must only be done when stove is cold. Open the door by lifting the handle. The glass
can be cleaned by wiping down the outside and inside of the glass with a dry soft cloth.
