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
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
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.
Defiant 1610
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,
•Using a section of
