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.

U.S.: 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.

The following illustration shows one NFPA-recom- mended method. All combustible material in the wall is cut away a sufficient distance from the single-wall connector to provide the required 12" (300 mm) 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" (230 mm) clearance to combustibles.

•Placing a chimney connector pipe inside a ventilated thimble, which is then separated from combustibles by 6" (150 mm) of fiberglass insulating material.

•Placing a chimney connector pipe inside a section of 9" (230 mm) diameter, solid-insulated, factory-built chimney, with two inches of air space between the chimney section and combustibles.

Canada: In Canada, the Canadian Standards Association has established different guidelines. The illustration below shows one method, in which all combustible material in the wall is cut away to provide the required 18" (460 mm) clearance 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 noncombustible spacers at least 1" (25 mm) 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 Resolute Acclaim into a factory-built (zero-clearance) fireplace under any circumstances. The Resolute Acclaim has not been specifically tested and listed for this type of instal- lation. 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 for

any other use.

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