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 inches (7.6 cm) of
clearance are necessary (see Figure 31).

A 10” (254 mm) x 10” (254 mm) frame (see Figure 32) 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 I
