Floor Protection

Vermont Castings Resolute Acclaim

Floor Protection

Atremendous amount of heat radiates from the bottom plate of your Resolute Acclaim. The floor area directly under and around the stove will require protection from radiant heat as well as from stray sparks or embers that may escape the firebox.

Heat protection is provided through the use of a Ver- mont Castings Bottom Heat Shield #0246. Spark and ember protection must be provided by a floor protector constructed with noncombustible material as specified.

Most installations will require that the bottom heat shield be attached. Only when the stove is placed on a completely noncombustible surface such as unpainted concrete over earth may it be used without the heat shield.

Even when the bottom heat shield is installed, you must provide special protection to the floor beneath. For installations with the heat shield attached, use a noncombustible floor protector such as 1/4” non- asbestos mineral board or equivalent, or 24 gauge sheet metal. The floor protector may be covered with a noncombustible decorative material if desired. Do not obstruct the space under the heater.

Protection requirements vary somewhat between the United States and Canada as follows:

U.S. installations the floor protector is required under the stove and must extend at least 16 inches from the front of the stove (“C”, Fig. 11), and at least 6 inches from the sides and rear ("D" and “E”,Fig. 11). It must also extend under the chimney connector and 2 inches to either side (“F”,Fig. 11).

To meet these requirements, a floor protector must be at least 38” wide and 42” deep.

In Canada, a noncombustible floor protector is required under the heater also. The floor protector must extend 18 inches (460 mm) to the front (“C”, Fig. 11), and 8 inches (200 mm) from the sides and rear (“D” and “E”, Fig. 11).

To meet these requirements, a floor protector must be at least 42” (1066mm) wide and 46” (1168mm) deep.

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 as in Figure 12. 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 combustible floor.

For all fireplace installations, follow the floor protection guidelines described above.

Keep in mind that many raised hearths will extend less than the required clearance from the front of the heater when it is installed. In such cases, sufficient floor protection as described above must be added in front of the hearth to satisfy the minimum floor protector requirement from the front of the stove: 16" (410 mm) from the front in the United States and 18" (460 mm) from the front in Canada.

Hearth rugs do not satisfy the requirements 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.
