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 1½” (38 mm) on the
sides and bottom. When combustible materials are directly above a 90° elbow, 3” (76 mm) of clearance
are necessary.

A 10” (254 mm) x 10” (254 mm) frame (see Figure 27) 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.
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

WARNING: This appliance has been designed to draw room air for proper heat circulation
from the bottom of the unit, and out the top front. Blocking or modifying these openings in
any way can create hazardous situations.
The vent length for the S20I/ S20ID must be between 7” (18 cm) and 44ft (13.4 m). This model is vented
with co-axial 4” intake, 6 5/8” exhaust aluminum or stainless steel approved rigid vent leading into a vertical
or horizontal termination cap. The flue collar of this model will fit inside of a standard 4” x 6 5/8” vent and
must be either correctly interlocked or fastened, with three screws directly to the vent.
Check periodically that the vents are unrestricted. Also ensure that all direct vent pipes have been properly
sealed and installed after routine inspection or cleaning. The air intake and exhaust pipes must be installed
in the correct location on top or rear of the S20I/ S20ID.
