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.
Keep in mind, also, that many raised hearths will extend
less than the required clearance 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
requirement from the front of the stove: 406 mm (16”)
from the front.

Combustible supporting timbers may lie beneath
fireplace hearths, requiring additional floor protection.
Hearth rugs do not satisfy the requirements for floor
protection.
Keep the Stove a Safe Distance
from Surrounding Materials
Both a stove and its chimney connector radiate heat in
all directions when operating, and dangerous overheat-
ing of nearby combustible materials can occur if they
are too close to the heat. A safe installation requires
that adequate clearance be maintained between the
hot stove and its connector and nearby combustibles.
Clearance is the distance between either your stove
(measured from the bottom edge of the stove’s top
plate) or chimney connector, and nearby walls, floors,
the ceiling, and any other fixed combustible surface.
Your stove has special clearance requirements that
have been established after careful research and test-
ing to both US and European standards. These clear-
Hearths
This appliance must be installed on to hearth that
meets the requirements of Part J of the Building Regu-
lations 2000 (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 2 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).
Unless the stove
hearth is completely
noncombustible, the
bottom heat shield
should be installed to
provide radiant protec-
tion for framing which
may be below the
hearth. (Fig. 11)
