Chimney/Vent System Cleaning:
1. Soot/Creosote 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 fl ue, as a result,
soot/creosote residue accumulates on the chimney lining. When ignited, soot/creosote makes an extremely hot fi re
which can damage the chimney or cause a house fi re. If a soot/creosote fi re occurs, shut down the heater immediately
and call the fi re department.
2. Soot and Flyash: Formation and Need for Removal—The products of combustion will contain small particles of fl yash.
The fl yash will collect in the exhaust venting system and restrict the fl ow of the fl ue 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:
Replacement glass must be 0.197" thick tempered ceramic glass with a working service temperature of 1400 deg. F.
Center Glass size: 10" x 10.67". Side glass size: 4" x 10.67"
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 wood stove cleaner.
2. Do not use abrasive cleaners.
3. Do not abuse the glass by striking or slamming the door.
