Optional 76 mm (3") short legs may be used only on such
hearths that meet the width and depth requirements outlined
previously under "floor protection."
Hearth rugs do not satisfy the requirements for floor
protection.
Fireplace installations also have special clearance
requirements 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 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 sufficient
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 included
below. There are no specific minimum clearances 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.
Summary of Clearances
M i n i m u m r e c o m m e n d e d s i d e c l e a r a n c e s t o
noncombustible surfaces 125 mm (5").
Minimum recommended rear clearance to noncombustible
surfaces 50 mm (2").
NOTE: The minimum thickness of solid noncombustible
materials is specified in section 2 of Document 'J', in relation
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) 760 mm (30") measured
from the rear edge of the stove top. (Figure 11, B)
Minimum side clearance from combustible walls 610
mm (24") measured from the side edge of the stove top.
(Figure 11, A)
Minimum distance from stove to movable combustible
materials (e.g. furniture, drying clothes, etc.) 760 mm
(30").
