available for this purpose.
(3) Sealant is optional, unless
specified by the appliance
manufacturer. Should you elect to use
sealant, it is only necessary on the outer
tube of the GS Pipe. Run a 1/8-inch
wide bead of sealant around the male
end of the outer sleeve, as shown in
Figure 5, and twist-lock the pipes or
fittings together.
Step 3. With the adaptor and
pipe attached to the fireplace, slide the
fireplace into it's correct location, and
mark the wall for a square hole of the
appropriate size. Use a 10"x10" square
hole for 7" x 4" pipe and use an 11"x11"
square hole for 8" x 5" pipe. The center
of the square hole should line up with
the centerline of the horizontal pipe, as shown in Figure 6. Cut and frame the square
hole in the exterior wall where the vent will be terminated. If the wall being
penetrated is constructed of noncombustible material, i.e. masonry block or
concrete, a hole with zero clearance to the pipe is acceptable.
Notes:
(1) The horizontal run of vent must be level, or have a 1/4-inch rise for every
1 foot of run towards the termination. Never allow the vent to run downward. This
could cause high temperatures and may present the possibility of a fire.
(2) The location of the horizontal vent termination on an exterior wall must
meet all local and national building codes, and must not be easily blocked or
obstructed. Termination clearances are as follows:
(a) Clearance above the ground, veranda, porch, deck or balcony -12
inches minimum.
(b) Clearance to a window or door that may be opened -9 inches
minimum.
(c) Vertical clearance to a ventilated soffit located above the
termination with a horizontal distance of 2 feet from the
centerline of the termination -18 inches minimum.
(d) Clearance to an unventilated soffit - 12 inches minimum.
