Wall Pass-Throughs

Whenever possible, design your installation so the connector does not pass through a combustible wall. If you must use a wall pass-through in your installation, check with your building inspector before you begin and construct it in accordance with local building codes. Also check with the chimney connector manu- facturer for any specific requirements.

Accessories are available for use as wall pass- throughs. If using one of these, make sure it has been tested and listed for use as a wall pass-through.

In the United States, the national Fire Protection Association (NFPA) has established guidelines for passing chimney connectors through combustible walls. Many building code inspectors follow these guidelines when approving installations.

Figure 10 shows one NFPA-recommended method. All combustible material in the wall is cut away a sufficient distance from the single-wall connector to provide the required 12” (305mm) clearance for the connector. Any material used to close up the opening must be noncom- bustible.

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

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

•Placing a chimney connector pipe inside a ventilated thimble, which is then separated from combustibles by 6” of fiberglass insulating material.

•Placing a chimney connector pipe inside a section of 8” diameter, solid-insulated, factory-built chimney, with 2” of air space between the chimney section and combustibles.

In Canada, the Canadian Standards Association has established different guidelines. Figure 11 shows one method, in which all combustible material in the wall is cut away to provide the required 18” (457mm) clear- ance for the connector. The resulting space must remain empty. 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 noncom- bustible spacers at least 1” (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 Sequoia 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.

Floor Protection

A tremendous amount of heat radiates from the bottom plate of your Sequoia 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
