Vermont Casting 0968, 1910 installation instructions Through the Fireplace, Wall pass-Throughs

Page 9

If the chimney connector in your installation enters the chimney above a fireplace, follow all the guidelines mentioned above for freestanding installations. In addition, give special consideration to the following points:

•Check the clearance between the stove and the chimney connector, and any combustible trim or the mantel.

•Check the clearance between the chimney connector and the ceiling. The clearance should be at least 18" (457 mm).

•The fireplace damper must be sealed to keep room air from escaping up the flue. However, it must be possible to reopen the damper to inspect or clean the chimney.

Through the Fireplace

Installations through the fireplace opening have not been tested or approved.

Wall pass-Throughs

Whenever possible, design your installation so that the connector does not pass through a combustible wall. If you are considering a wall pass-through in your installation, check with your building inspector before you begin. Also, check with the chimney connector manufacturer 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 8 shows one NFPA-recommended method. All combustible material in the wall is cut away from the single-wall connector to provide the required 12" (300

mm)clearance. Any material used to close up the opening must be noncombustible.

Three other methods are also approved by the NFPA:

• Placing a section of chimney connector inside a ventilated thimble, which in turn is separated from combustibles by 6" (150 mm) of fiberglass insulat- ing material.

• Placing a section of chimney connector 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.

• Using a section of solid-insulated double-wall High Temperature chimney, with an inside diameter the same as the chimney connector, at least one inch of solid insulation, and a minimum of 9 inches (229mm) air space between the outer wall of the chimney section and combustibles.

In Canada, The Canadian Standards Association has established different guidelines for wall pass- throughs. Figure 9 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 for other approved methods of passing a chimney connector through a combustible wall in your area. In Canada, this type of installation must conform to CAN/CSA-B365, Installation Code for Solid Fuel Burning Appliances and Equipment.
