Figure 19. Vent Framing Through Wall/Ceiling
Figure 18. Vent Pipe Clearances.
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 1” (38 mm) on the sides and bottom. When
combustible materials are directly above a 90° elbow, 5” (127
mm) of clearance are necessary. See Figure 18
A 10” (254 mm) x 10” (254 mm) frame (see Figure 19) 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
conguration 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 efciency of the replace, certain guidelines have
been set in INITIAL INSTALLATION - VENT CONFIGURATIONS AND
RESTRICTOR SETTINGS.
Venting terminals can not be recessed into
a wall or siding.
WARNING: This gas appliance must
not be connected to a chimney ue
serving a separate solid-burning
appliances.
