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.  See page 17, 
Figure 5.15.   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) located on page 12.
NOTE:   Maximum vertical rise allowable is 35 ft. (11m), 
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 12).

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 5.12 to avoid 
cutting loadbearing members.
