Installation

Installing 

Place the stove on a non-combustible floor protector that extends a minimum of 6 inches to the front (152mm), 6 inches 

to the sides (152mm) and 0"(152mm) to the rear, which is flush with the rear of the hopper. Front and side floor protection 

measurements are made from the firebox or window opening. Floor protection must also be positioned under horizontal flue 

pipe, extending 2" (51mm) beyond each side of the pipe. 

NOTE for Canadian installation only:

  Per  ULC-S627-00,  If  installed  on  a  combustible  floor,  the  need  to  provide  a 

noncombustible 

floor protector 

covering the area beneath the 

space heater 

and extending at least 17.72" (450mm) on the 

firing side and at least 7.87" (200mm) on the other sides.

In Canada, you may follow smaller U.S. floor protection requirements ONLY if the user agrees to completely shut-

down the appliance, and allow it to cool to where all fire is extinguished and the combustion blower and its indicator 

light shuts off, prior to opening the firebox door or ash door.

The minimum floor protector material is 20 gauge sheet metal. Other floor protector materials are ceramic tile, stone, brick, etc.
Place the stove away from combustible walls at least as far as shown in Figures 2 and 3.
Note that the clearances shown are minimum for safety but do not leave much room for access when cleaning or servicing. 

Please take this into account when placing the stove.
