Vermont Casting 2550CE Safe Ways to Reduce Clearances, Summary of Clearances

Encore Woodburning Stove

ance requirements must be strictly observed.

In addition, furnishings and other combustible materials must be kept away from the stove as well. In general, a distance of 1219 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.

Safe Ways to Reduce Clearances

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.

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 noncombustible materials is specified in section 2 of Document ‘J’, in relation to the clearance of the appliance from the sur- face. As a general rule, the thickness of solid noncom- bustible 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) 1000 mm (39³⁄₈”) measured from the rear edge of the stove top. (Fig. 12, B)

Minimum side clearance from combustible walls 610 mm (24”) measured from the side edge of the stove top. (Fig. 12, A)

Minimum distance from stove to movable combus- tible materials (e.g. furniture, drying clothes, etc.) 1220 mm (48”).

Connecting Flue Pipe - Clearances

Single wall connecting fluepipes can reach extremely high temperatures; therefore, clearances from the con- necting fluepipe (chimney connector) must comply with the requirements of Part J of Building Regulations 2000 (Combustion Appliances and Fuel Storage Systems). This can be achieved by following the recommenda- tions of Approved Document ‘J’. These are as shown in Figure 13.
