must be possible to re-open the damper to inspect or clean the chimney.

Through the Fireplace

If your fireplace opening height is at least 29" (737 mm), you may install a Defiant through the opening using a “positive connection” kit, available from your local deal- er. Positive connection kits ensure a tight fit between the stove flue collar and the chimney flue. (Fig. 9)

Fireplace installations, whether connected to the flue above or through the fireplace opening, have special clearance requirements to adjacent trim and the mantel. You’ll find the required safe clearances for Defiant fire- place installations on Page 12.

Floor protection requirements also apply to fireplace installations. This information is on Page 10.

Wall Pass-Throughs

Whenever possible, design your installation so the con- nector 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 As- sociation (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 from the single-wall connector to provide the required 12” (305

mm)clearance. Any material used to close up the open- ing 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” (152mm) of fiberglass insulating material.

•Placing a section of chimney connector inside a section of 9” (230mm) diameter, solid-insulated, factory-built chimney, with 2” (50mm) 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” (229 mm) 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 11 shows one method, in which all combustible material in the wall is cut away to provide the required 18” (457mm) 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” (25mm) clear of the wall.
