Step 1.
Check the installation instructions for required 1 in. (25mm)
clearances (air space) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters, or
other nearby combustible surfaces.
Figure 5.17 on page
17. 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
Figure 5.2 on page 11.
NOTE: Maximum vertical rise allowable is 40 ft. (12m)
Figure 5.11.
NOTE: Maximum number of 45° elbows permitted for a
vertical installation is eight, provided their installation
does not decrease maximum allowable horizontal run (as
specified by vent graph, on
page 11).

Step 2.
S et the gas appliance in its desired location. Drop a plumb
bob down from the ceiling to the position of the appliance
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
appliance, or to offset, as shown in
Figure 5.13 on page
16, to avoid cutting loadbearing members. When location is
determined, drill small hole.

Failure to keep insulation or other materials away
from vent pipe may cause fi re.
