FLOOR PROTECTION
This appliance does not require thermal hearth pad fl oor protection; however,
if installed on a combustible fl oor, a non-combustible fl oor shield must be
used. In the USA, this fl oor shield must extend 16” out from the front and 8”
out from either side of the fuel-loading door. In Canada, to comply with CSA
B365, any combustible covering beneath the appliance and/or within the area
extending horizontally at least 18” (450 mm) beyond the appliance on any side
equipped with a door, and at least 8” (200 mm) beyond the appliance on other
sides, shall be protected by a continuous, durable, non-combustible pad that
will provide ember protection. The 18” (450 mm) ember protection required on
any side with a door shall extend for the full width of the appliance plus the
8” (200 mm) required on each side of the appliance without a door. Where an
appliance is installed less than 8” (200 mm) from a wall, the ember pad need
only extend to the base of the wall. An ember pad shall not be placed on top
of a carpet unless the pad is structurally supported to prevent displacement
and distortion.
A non-combustible shield is also required underneath the chimney connector and
extend at least 2” on either side of the chimney connector. This shield does
not need an insulation value, but must be listed under UL 1618-2009 (Type 1)
and have a minimum size of:
32” x 40.125” (813 mm x 1019 mm) in USA or 42.75” x 50.125” (1086 mm x 1273
mm) in Canada.
Blaze King does not recommend adhesive based vinyl fl ooring in front of
appliances due to thermal expansion and warping which could be permanent.
