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.
