Yearly Maintenance (or Every Ton of Pellets) - Clean the Vent
Flyash will deposit along
sections that are horizontal.
WHENEVER ANY PORTION OF THE PELLET VENT IS DISCONNECTED, THE JOINTS MUST
BE SEALED WITH RTV 500° F. SILICONE SEALANT, UNLESS OTHERWISE SPECIFIED BY
THE VENT MANUFACTURER.
Every Two Years (or Every 4 to 6 Tons of Pellets) Chisel Replacement

The chisel is designed to shear pellets during operation. As the chisel becomes dull over time it will make
it harder for the appliance to shear pellets and could shorten the life of the feed motor. We recommend
that the chisel be replaced every two years or 4 to 6 tons of pellets to help ensure proper operation of the
appliance.

To remove the chisel, first, remove all pellets from the hopper. Turn the appliance on and turn the heat
rate to "HIGH". The hopper lid switch will need to be held in the closed position (AGP appliances) or the
hopper lid will need to be closed and you can look through the glass lid (Deerfield & Foxfire stoves) for
the feed system to turn. The chisel will rotate into view (it is the serrated component held in place with
two screws). Once the chisel is in the proper position, unplug the heater and remove the cover plate at
the bottom of the hopper (6 screws hold it in place). The chisel is held in place with two cap head screws
(use a 1/8" hex wrench to remove). Remove the chisel and replace it with a new chisel (available from
your dealer). NOTE: There is a shim (2 shims on older units) under the chisel – make sure to
replace the shim when installing the chisel. When replacing the cover plate, make sure to place the
gasket between the cover plate and the hopper (use silicone if gasket is not used). This prevents pellet
dust from falling below. Return the heater to the correct configuration before operating.

Make sure the cap is free of debris
(especially if it has a screen that could
become blocked).
Check the vent sections for creosote
accumulation (indicating a poorly burning
stove). Accumulation over 1/4" must be
removed.
On vertically vented systems, the dirtiest portion
is often the point where the vent turns upwards
(i.e. the "Tee"). Fortunately, the "Tee" has a built-
in clean-out cover. Place a container under the
"Tee", disconnect the cover and remove all flyash.
While open, use a flashlight to look up the vent to
check for build-up.
