MAINTENANCE ‐ continued
Chimney/Vent System Cleaning:
1. Soot Formation – When wood products are burned slowly they produce tar and other organic vapors which
combine with expelled moisture to form soot. The soot vapors condense in the relatively cool chimney flue, as
a result soot residue accumulates on the chimney lining. When ignited soot makes an extremely hot fire which
can damage the chimney or cause a house fire. If a soot/creosote fire occurs, shut down the heater
immediately and call the fire department.
2. Soot and Flyash: Formation and Need for Removal—The products of combustion will contain small particles
of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases.
Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater
will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system
should be inspected at least once every year or per ton of fuel burned to determine if cleaning is necessary.
Door Gaskets:
Gaskets around the door and window panes should be inspected, cleaned and repaired when necessary to
maintain good seal.
Door Glass Removal and Replacement:
Do not attempt to operate the unit with broken glass. Replacement glass may be purchased from your U.S. Stove
Pellet Burning Room Heater Dealer. If glass is broken, follow these removal procedures:
1. Once the heater has cooled, remove the door from the heater.
2. Remove the rope gasket from the door followed by the eight(8) nuts holding the glass retainer in place.
3. While wearing gloves, carefully remove any loose pieces of glass from the door frame.
4. Replace the glass and gasket, making sure the gasket runs the full perimeter of the glass edge.
5. Re‐install the retainer and eight nuts and rope gasket using high temperature silicone to adhere the gasket
to the door.
6. Never use substitute materials for the glass.
Glass Cleaning: (Clean as needed)
1. Do not attempt to clean the glass while unit is hot. Wait until the pellet heater has cooled and then use a
soft cotton cloth and mild window cleaner or gas and woodstove cleaner.
2. Do not use abrasive cleaners.
3. Do not abuse the glass by striking or slamming the door.
