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 spac-
ers at least 5 mm (1”) clear of the wall.
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.

floor protection for fireplace installations
Do not assume that your fireplace hearth is completely
noncombustible.
Many fireplace hearths do not meet the “completely
noncombustible” requirement because the brick or
concrete in front of the fireplace opening is supported
by heavy wood framing. (Fig. 11) Because heat passes
through brick or concrete readily, it can easily pass
through to the wood. As a result, such fireplace hearths
can be a fire hazard and are considered a combustible
floor.
hearths
This appliance must be installed on to hearth that
meets the requirements of Part J of the Building Regu-
lations 000 (Combustion Appliances and Fuel Storage
Systems). This can be achieved by ensuring that the
hearth is constructed and sized in accordance with the
guidelines included in section of approved document
‘J’. The size and clearances of the hearth are as fol-
lows:
The constructed hearth should be constructed in ac-
cordance with the recommendations in document J,
and should be of minimum width 840 mm and minimum
depth 840 mm (if a free standing hearth b) above) or
a minimum projection of 150 mm from the jamb (if a
recessed hearth a) above).

Combustible supporting timbers may lie beneath
fireplace hearths, requiring additional floor protection.
Keep in mind, also,
that many raised
hearths will extend less
than the required clear-
ance from the front
of the heater when it
is installed. In such
cases, sufficient floor
protection as described
above must be added
in front of the hearth
to satisfy the minimum
floor protector require-
ment from the front of
the stove: 406 mm
(16”) from the front.
Hearth rugs do not sat-
isfy the requirements
for floor protection.
Fireplace installations
also have special clearance requirements to the side
walls, side decorative trim, and fireplace mantel. This
information follows in the section on Fireplace and Man-
tel Trim Shields.
