FLOOR  PROTECTION:    Floor  protector  must  be  noncombustible  material,  extending  beneath  heater  and  to  the 
front/sides/rear  as  indicated.    The  floor  must  be  non-combustible  or  otherwise  adequately  protected  from  radiant  heat 
given off by the unit and from sparks and falling embers. A layer of thin brick or ceramic tile over a combustible floor is not 
sufficient. A listed hearth pad that has a “k” value of .84 or lower meets this requirement.
In USA installations, it is necessary to install a floor protector of 1/2" thick metal clad millboard (“k” value = .84) or equivalent 
at least 16" in front of glass door and 8" to both sides of the fuel loading door. Open the door and measure 8” from the side 
edge of the opening in the face of the stove. See *exception below. 
See Alternate Materials Worksheet on 
Page 9 to determine if alternate floor protection materials are acceptable.
In  Canada,  similar  floor  protection  must  be  provided  18"  (457mm)  in  front  and  8"  (203mm)  from  the  sides  and  rear 
of the stove. See *exception below.
*EXCEPTION:  Non-combustile floor protection must extend beneath the flue pipe when installed with horizontal venting 
and extend 2” (51mm) beyond each side.
