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 16, 

5.17.   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) located on page 11.

Fire Risk.

Explosion Risk.

Maintain vent clearance to combustibles as speci-
