USING GS SERIES PIPE
Step 1. Check the installation instructions for required
1" clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures,
attic rafters, or other nearby combustible surfaces.
See page 24, Fig. 16. Do not pack air space
with insulation. Check the instructions below for
maximum vertical rise of the venting system, and
any maximum horizontal offset limitations. All
offsets must fall within the set parameters of the
vent graph located on page 18.
NOTE: Maximum vertical rise allowable is 40'. Figure 10.
NOTE: Maximum number of 45° elbows permitted for
a vertical installation is eight, provided their
installation does not decrease maximum vertical
rise (as specifiedby Vent graph, on page 16).
NOTE: Maximum number of 90° elbows permitted for a
vertical installation is four, provided the termination
falls within the shaded area shown in vent graph on
page 18. See also Figure 12 above. ADDITIONAL
RESTRICTION: This installation may not have two
horizontal sections connected by 90° elbows.
Step 2. Set the gas stove in its desired location. Drop a
plumb bob down from the ceiling to the position of
the stove flue exit, and mark the location where the
vent will penetrate the ceiling. Drill a small hole at
this point. Next, drop a plumb bob from the roof to
the hole previously drilled in the ceiling, and mark
the spot where the vent will penetrate the roof.
Determine if ceiling joists, roof rafters, or other
framing will obstruct the venting system. You
may wish to relocate the stove, or to offset, as
shown in Figure 11, to avoid cutting loadbearing
members.
Step 3. To install the round support box/wall thimble in
a flat ceiling, cut a 10" (254mm) square hole in
the ceiling, centered on the hole drilled in Step 2.
Frame the hole as shown in Figure 13.
