Keep the Stove a Safe Distance
from Surrounding Materials
Specifications herein are primarily related to common timberframe construction. Both a stove and its chimney connector radiate heat in all directions when operat- ing, 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 surface. Your stove has special clearance requirements that have been established after careful research and testing. These clearance requirements must be strictly ob- served.
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 dry- ing 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 includ- ed 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
Minimum recommended side clearances to non- combustible surfaces 125 mm (5”).
Minimum recommended rear clearance to noncom- bustible surfaces 50 mm (2”).
NOTE: The minimum thickness of solid noncombus- tible 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 non- combustible 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. (Fig. 10, B)
Minimum side clearance from combustible walls 610 mm (24”) measured from the side edge of the stove top. (Fig. 10, A)
Minimum distance from stove to movable combus- tible materials (e.g. furniture, drying clothes, etc.) 1220 mm (48”).
