How to Install the stove
The stove should be installed by a licensed stove company or a licensed HVAC Technician. Some states and counties require permits be obtained before you install
your stove.
The outlet on the bottom combustion blower motor is 3" in diameter. Double wall pipe with stainless steel for the inner liner must be used in all installs. It is most
commonly called Pellet Pipe. Three inch (3 inches) (76mm) diameter Listed DOUBLE WALL pipe with MH8381
& MH14420) to UL 641 Type L Low Temperature Venting Systems** Listed factory-built Class "A" chimney, or
a masonry chimney.(**In Canada must comply with Standard CAN/ULC-S629-M87 for the 650oC Factory-built chimney.)
FLOOR PROTECTION:
Floor protector must be 1/2 in. minimum noncombustible material extending beneath heater and to front/sides/rear as indicated on the diagram below.
Exception: Non-combustible floor protections must extend beneath the flue pipe when installed with horizontal venting and extend 2 inches (51mm)
beyond each side.
The stove is designed to be pushed back to within inches of the back wall and to be at least one foot from any sidewalls or any other surface. Check with your local
permit inspector to verify your clearance from combustibles in your state. We have UL specifications on the stove for clearance to combustibles. Add here after
striking 8. Refer to this manual and the drawings for install specifications.
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote
vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When
ignited this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected at least once every two months during the heating season to determine if a creosote
buildup has occurred. If creosote has accumulated, it should be removed to reduce the risk of a chimney fire.
Using "Make-Shift" parts or not following the guidelines of correct installation procedures and clearances can result in failure of the stove or a fire
in your home.
The chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a floor, or ceiling. Where passage
through a wall or partition of combustible construction is desired, the installation shall conform to Can/CSA-B365, Installation Code for Solid-Fuel-
Burning Appliances and Equipment.
Clearances may only be reduced by means approved by the regulatory authority.
DO NOT INSTALL IN A MOBILE HOME.
IT IS RECOMMENDED IN CASE OF POWER OUTAGE TO HAVE AT LEAST 2 FT OF RISE ABOVE MOTOR ELEVATION
