death. Any unauthorized modification of the stove or Heat Distribution Kit is prohibited. All national and local
regulations must be followed when operating this pellet stove with Heat Distribution Kit option.
WARNING: DO NOT INSTALL IN SLEEPING ROOM.
CAUTION: THE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL, AND
CEILING/ROOF MUST BE MAINTAINED.
Installation: Ducting must have 1” clearance to any combustible material when going through a wall or floor.
Do not use plastic registers, metal registers must be used for Heat Distribution Kit installation. Do not cover or
block outlet registers.
Do not have combustible materials touching outlet registers. Give wall registers at least 6 inches of clearance to
furniture, clothing ect.
Do place anything directly above or in contact with floor registers. The installer must use supplied 1/4 inch insulation
between register adapters and combustible building materials. Ducting register adapters can not be installed with zero
clearance.
Unit can not be ducted into previously existing heating appliance ducts. Ducts for HDK must be installed as per manual.
Duct runs should be 20ft or less, output will greatly decline after this length.
Operation: Metal registers attached to Heat Distribution Kit ducting must be open during operation.
Do not touch any part of stove or Heat Distribution Kit while stove is running. Unit is hot during operation. Keep
children, clothing and furniture away. Contact may cause skin burns. After unit is off give at least one hour before
touching stove, registers, or refueling.
To access Heat Exchanger cleaning rods remove front grills. Wait until unit is cool to access.
