Floor Protection for Fireplace Installation
Do not assume that your fireplace hearth is completely
noncombustible. Many fireplace hearths do not satisfy
the “completely noncombustible” requirement because
the brick or concrete in front of the fireplace opening
is supported by heavy wood framing. Because heat
passes readily through brick or concrete, it can easily
pass through to the wood. As a result, such fireplace
hearths can be a fire hazard and are considered a com-
bustible floor.
For all fireplace installations, follow the floor protection
guidelines described above, including the need for bottom
and ash door heat shields. Keep in mind that many raised
hearths will extend less than the required clearance from
the front of the heater. In such cases, sufficient floor pro-
tection as described above must be added in front of the
hearth to satisfy the minimum floor protector requirement
from the front of the stove: 410 mm (16”). Hearth rugs do
not satisfy the requirement for floor protection as they are
not fire proof.
Fireplace installations also have special clearance
requirements to the side walls, side decorative trim and
fireplace mantel. Refer to the information on fireplace
and mantel trim shields in this section.
Keep the Stove a Safe Distance
From Surrounding Materials
Both a stove and its chimney connector radiate heat in
all directions when operating, and nearby combustible
materials can overheat dangerously if they are too close
to the heat source. A safe installation requires that ad-
equate clearance be maintained between the hot stove
and its connector and nearby combustibles.
Clearance is the distance between either your stove or
chimney connector, and nearby walls, floors, the ceiling,
and any other fixed combustible surface. The Defiant
has specific clearance requirements that have been
established after careful research and testing. These
clearance requirements must be strictly observed.
In addition, keep furnishings and other combustible
materials away from the stove. In general, a distance
of 1219 mm (48”) must be maintained between the
stove and moveable combustible items such as drying
clothes, furniture, newspapers, firewood, etc. Keep-
ing those clearance areas empty assures that nearby
surfaces and objects will not overheat.
Clearances
As with any solid fuel heating stove, extremely high
surface temperatures can occur, particularly in the
event of uncontrolled operation, e.g. if the doors
are inadvertently left open. It is crucial that suf-
ficient clearances are allowed to any combustible
surfaces, e.g. wooden mantels or lintels, and to
timber framed (studded) walls even if they are faced
with noncombustible board. Detailed information
on fireplace and hearth construction is provided
in section 2 of Document J, all installations must
comply with these requirements or with the relevant
National or local building standards.
Clearances to timber framed (studded) walls are in-
cluded below. There are no specific minimum clearanc-
es to solid noncombustible surfaces (e.g. the sides and
rear of Inglenook fire openings constructed from solid
masonry) other than to allow safe access to the controls
of the stove. For this reason minimum side clearances
of 125 mm, and a minimum rear clearance of 50 mm
are recommended.
