A Brick Pass thru - Approved In the United States
In Canada, The Canadian Standards Association has es-
tablished installation guidelines. The following illustration
shows one method, in which all combustible material in the
wall is cut away to provide the required 18" (457 mm) clear-
ance for the connector. The resulting space must remain
empty. A flush-mounted sheet metal cover may be used
on one side only. If covers must be used on both sides,
each cover must be mounted on noncombustible spacers
at least 1" (25 mm) clear of the wall. Figure 15
Your local dealer or your local building inspector can
provide details for other approved methods of passing
a chimney connector through a combustible wall in your
area. In Canada, this type of installation must conform to
CAN/CSA-B365, Installation Code for Solid Fuel Burning
Appliances and Equipment.
NOTE: Do not vent your Challenger into a factory-built
(zero-clearance) fireplace. These appliances and their
chimneys are specifically designed as a unit for use as
fireplaces. It may void the listing or be hazardous to adapt
them for any other use.
dO NOT CONNECT AN CHALLENGER TO ANY AIR
dISTRIBuTION duCT OR SYSTEM.

Floor Protection

A tremendous amount of heat radiates from the bottom plate
of your stove. The floor area directly under and around the
stove will require protection from radiant heat as well as from
stray sparks or embers that may escape the firebox.
Spark, ember and thermal protection must be provided by
a floor protector constructed with noncombustible material
as specified.

Special protection for the floor beneath the stove must be
provided. Use an approved 1" (25 mm) noncombustible
ST1150
hearth pad with K = 0.84 BTU/in ft
material with an R-value of at least 1.19. (Refer to "How
hollow wall pass thru
to Determine if Alternate Floor Protection Materials are
Acceptable" section) The floor protector may be covered
with a decorative noncombustible material if desired. Do
not obstruct the space under the heater.
Protection requirements vary somewhat between the
United States and Canada as follows:
U.S. Installations: The floor protector is required under the
stove and must extend at least 16" from the front of the
stove, and at least 8" from the sides and rear. Figure 16
In Canada: a noncombustible floor protector is required
under the heater also. The floor protector must extend 18"
(457 mm) from the front of the stove, and at least 8" (203
mm) from the sides and rear. Figure 16
How to determine if Alternate Floor Protection Materi-
als are Acceptable
All floor protection must be noncombustible (i.e. metals,
brick, stone, mineral fiber boards, etc.). Any organic materi-
als (i.e. plastics, wood paper products, etc.) are combus-
tible and must not be used. The floor protection specified
includes some form of thermal designation such as R-value
(thermal resistance) or k-factor (thermal conductivity).
Procedure:
1. Convert specifications to R-value:
i. R-value given - no conversion needed.
ii. k-factor is given with a required thickness (T) in
1
inches:
R = x T
k
iii. K-factor is given with a required thickness (T) in
1
inches:
R =
K x 12
