NOTES:  
(1)  The four (4) wood screws provided should be replaced with the appropriate fasteners for stucco, 

brick, concrete, or other types of siding.

(2)  For buildings with vinyl siding, a vinyl siding standoff, should be installed between the vent cap and 

the exterior wall (see Figure 19). Attach the vinyl siding standoff to the horizontal termination. The 

vinyl siding standoff prevents excessive heat from possibly melting the vinyl siding material. Note 

that the horizontal vent termination bolts onto the flat portion of the vinyl siding standoff (shaded 

area in Figure 20), so that an air space will exist between the wall and the vent termination.

NOTES:  
(1)  The horizontal run of vent pipe must be level and should have a 1⁄4 inch rise for every one foot 

of run towards the termination. Never allow the vent to run downward. This could cause high 

temperature and may present the possibility of a fire.

(2)  The location of the horizontal vent termination on the exterior wall must not be easily blocked or 

obstructed. Refer to I

(3)  When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).
(4)  Maintain manufacturer’s clearances to combustibles with venting.

Do not interfere with the structural integrity of the walls.
For installations with a 36” (915 mm) snorkel refer to Figure 21 and ‘Initial Installation - Installation of 

Rear Vented’.
