B. Hearth Protection Requirements
FLOOR PROTECTION:
Floor protector must be non-combus-
tible material, extending beneath appliance and to the front,
sides and rear as indicated. The floor must be non-combusti-
ble or otherwise adequately protected from radiant heat given
off by the appliance and from sparks and falling embers. A
layer of thin brick or ceramic tile over a combustible floor is
not sufficient.
It is necessary to install a Type I floor protector with a min-
imum of 16 inches (406mm) in front of glass and 8 inches
(203mm) to both sides of the fuel loading door. Open the
door and measure 8 inches (203mm) from the side edge of
the opening in the face of the appliance.
In Canada,
similar floor protection must be provided 18 inches
(457mm) in front and 8 inches (203mm) from the sides and
rear of the appliance.
