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.  

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).

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 

16, to avoid cutting loadbearing members. When location is 
determined, drill small hole.

Fire Risk.

Explosion Risk.

Maintain vent clearance to combustibles as speci-
fi ed.

•  Do not pack air space with insulation or other 

materials.

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