VENTING:
This fireplace has been tested and certified for use with SIMPSON DURAVENT DIRECT VENT TYPE “GS” PIPE FOR GAS STOVES, SECURITY CHIMNEY’S SECURE VENT DIRECT VENT SYSTEM kits, AMERICAN METAL PRODUCTS AMERIVENT DIRECT and
A 1” (25 mm) clearance to combustibles must be maintained around any vertical vent pipe. Around a horizontal vent pipe, the clearance to combustibles should be 2” (51 mm) above and 11⁄2” (38 mm) on the sides and bottom. When combustible materials are directly above a 90° elbow, 3” (76 mm) of clearance are necessary (see Figure 28).

A 10” (254 mm) x 10” (254 mm) frame (see Figure 29) will assure the proper support and spacing for the vent pipe as it passes through the wall. Installations in Canada require that a wall thimble be used for passing through walls and ceilings. All sealing and vapour barriers must comply with local building codes.
When planning an installation, it is necessary to select the proper length of vent pipe for the particular requirements. The configuration of the venting pipes depends on the locations of walls, ceilings, and studs. However, the pipes cannot be of arbitrary length and arrangement. Because the length of the vertical and horizontal
sections dramatically affects the burning efficiency of the
fireplace, certain
guidelines have been set in INITIAL
