Vermont Casting 2479 manual Floor Protection, Canada

A flush-mounted sheet metal cover may be used on one side only. If covers must be used on both sides, each cover must be mounted on non-combustible spacers at least 1” (25 mm) clear of the wall. Your Dutchwest dealer or your local building inspector can provide de- tails of other approved methods of passing a chimney connector through a combustible wall. In Canada, this type of installation must conform to CAN/CSA-B365, Installation Code for Solid Fuel Burning Appliances and Equipment.

NOTE: Do not vent your Dutchwest stove into a factory- built (zero-clearance) fireplace. These appliances and their chimneys are specifically designed as a unit for use as fireplaces. It may void the listing or be hazard- ous to adapt them for any other use.

Floor Protection

A tremendous amount of heat radiates from the bottom plate of your Dutchwest stove. 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 by the CFM Corporation Bottom Heat Shield. Spark, ember and thermal protec- tion must be provided by a floor protector constructed with noncombustible material as specified.

In the US and Canada most installations will require that the bottom heat shield must be attached. Only when the stove is placed on a completely noncombusti- ble 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 installation with the heat shield attached, use an approved 1” (25mm) noncombustible hearth pad with K

=0.84 BTU/in ft2 hr °F or an equivalent material with an R-value of at least 1.19. (Refer to “How to Determine if Alternate Floor Protection Materials are Acceptable” section) The floor protector may be covered with a decorative noncombustible 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” from the front and left (loading door) side of the stove, and at least 6” from the right side and rear. (Fig. 12)

In Canada: a noncombustible floor protector is required under the heater also. The floor protector must extend 18” (457mm) from the front and left (loading door) side of the stove, and at least 8” (203mm) from the right side and rear. (Fig. 12)

Fig. 13 Combustible supporting timbers (A) may lie beneath fireplace hearths; such situations require additional floor protection.

Due to the side loading door, floor protector require- ments call for more protection on the left side than on the right. If you wish a more balanced look, increase the other side of the hearth as well. Do not reduce side protection under any circumstances.

How to Determine if Alternate Floor Protection Ma- terials are Acceptable

All floor protection must be noncombustible (i.e. metals, brick, stone, mineral fiber boards, etc.). Any organic materials (i.e. plastics, wood paper products, etc.) are combustible and must not be used. The floor protection specified includes some form of thermal designation such as R-value (thermal resistance) or k-factor (ther- mal conductivity).
