Floor Protection

Dutchwest Seneca

Many building code inspectors follow these guidelines when approving installations.

Figure 9 shows one NFPA-recommended method. All combustible material in the wall is cut away a sufficient distance form the single-wall connector to provide the required 12Ó clearance for the connector. Any material used to close up the opening must be noncombustible.

Three other methods are also approved by the NFPA. These are:

•Using a section of double-wall chimney with a 9 inch clearance to combustibles.

•Placing a chimney connector pipe inside a ventilated thimble, which is then separated from combustibles by six inches of fiberglass insulating material.

•Placing a chimney connector pipe inside a section of 8 inch diameter, solid-insulated, factory-built chim- ney, with two inches of air space between the chimney section and combustibles.

In Canada, the Canadian Standards Association has established different guidelines. Figure 10 shows one method, in which all combustible material in the wall is cut away to provide the required 18Ó (450mm) clear- ance for the connector. The resulting space must remain empty. A flush-mounted sheet metal cover may be using on one side only. If covers must be used on both sides, each cover must be mounted on noncom- bustible spacers at least 1Ó (25mm) clear of the wall. Your local dealer or your local building inspector can provide details 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 Seneca 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 hazardous to adapt them to any other use.

DO NOT CONNECT THE HEATER TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.

A tremendous amount of heat radiates from the bottom plate of your Seneca 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 through the use of a Dutchwest Bottom Heat Shield. 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 installation 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 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:
