1.3.1 Reduced clearances
You may decrease the clearances by installing heat radiation shields between the walls or
the ceiling and the stove. These heat radiation shields must be installed permanently, and
can include sheet metal, a rigid non-combustible sheet or a masonry wall.
Clearances of not less than 1" (25 mm) and not more than 3" (76 mm) between the bottom
of the shield and the floor and not less than 3" (76 mm) between the top of the shield and
the ceiling must be respected to allow vertical air circulation behind the shield. The shield
must extend 20" (500 mm) above the stove top and 18" (450mm) to each side of the stove
(see Graphic 1).
Following the installation of such a heat radiation shield, the clearances mentioned on the
stove certification plate may be reduced as stated in the following table.
