Optional 76 mm (3") short legs may be used only on such
hearths that meet the width and depth requirements out-
lined previously under “floor protection.”
Hearth rugs do not satisfy the requirements for floor pro
-
tection.
Fireplace installations also have special clearance require-
ments to the side walls, side decorative trim, and fireplace
mantle. 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 dangerous overheating
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 back edge of the stove’s top plate) or
chimney connector, and nearby walls, floors, the ceiling,
and any other fixed combustible surfaces. In addition,
furnishings and other combustible materials must be
kept away from the stove as well. In general, a distance
of 1220 mm (48") must be maintained between the stove
and moveable combustible items such as drying clothes,
furniture, newspapers, firewood, etc. Keeping those clear
-
ance 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 sufficient clear
-
ances are allowed to any combustible surfaces, e.g.
wooden mantels or lintels, and to timber framed (stud-
ded) 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 require-
ments or with the relevant National or local building
standards.
Clearances to timber framed (studded) walls are included
below. There are no specific minimum clearances to solid
noncombustible
surfaces (e.g. the sides and rear of Ingle-
nook 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.
Summary of Clearances
Minimum recommended side clearances to noncom-
bustible surfaces 125 mm (5").
Minimum recommended rear clearance to noncombus-
tible surfaces 50 mm (2").
NOTE:
The minimum thickness of solid noncombustible
materials is specified in section 2 of Document ‘J’, in rela
-
tion to the clearance of the appliance from the surface.
As a general rule, the thickness of solid noncombustible
material forming the recess of a fireplace is a minimum of
200 mm.
Minimum rear clearance from combustible walls (e.g.
timber framed or studded walls) 610 mm (24") mea-
sured from the rear edge of the stove top. (Fig. 11, B)
Minimum side clearance from combustible walls 610
mm (24") measured from the side edge of the stove
top. (Fig. 11, A)
