NOTE:
(1) Installation requires a minimum of 6 in. (152mm) 
horizontal run of vent with a 1/4 in. (6mm) rise run towards 
the termination. Each 1 ft. (305mm) of horizontal venting 
must include a 1/4 in. (6mm) rise.  Never allow the vent 
to run downward. This could cause high temperatures 
and may present the possibility of a house or structure 
fire.
(2)  The location of the horizontal vent termination on an 
exterior wall must meet all local and national building

Step 4. 
Position the horizontal vent termination cap in the center of 
the 10 in. x 10 in. (254mm x 254mm) square hole and run a 
bead of non-hardening mastic around its outside edges, so 
as to make a seal between it and the wall, attach termination 
cap to the exterior wall with the four wood screws provided. 
The arrow on the vent cap should be pointing up (Figure

).

NOTES:
(1)  The four wood screws provided should be replaced with 
appropriate fasteners for stucco, brick, concrete, or 
other types of sidings.
(2)   A termination cap with a built-in vinyl siding standoff is  
highly recommended on a building with vinyl siding. The 
pilot hole will be 2 in. (51mm) closer to the bottom of the 
square than the top. Using a framing square, draw a 14 
in. x 14 in. (356mm x 356mm) square around the pilot 
hole in the siding. See Figure 5.7 on the next page.
Step 3. 
For installations using a round support box/wall thimble 
(check pipe manufacturer's instructions), mark the wall for a 
10 in. x 10 in.  (254mm x 254mm) square hole.  The center 
of the square hole should line up with the center line of the 
horizontal pipe, as shown in Figure 5.5.  Cut and frame the 
hole in the exterior wall where the vent will be terminated.  If 
the wall being penetrated is constructed of noncombustible 
material, i.e. masonry block or concrete, a 7 in. (178mm) 
diameter hole is acceptable.  
Fire Risk.
Explosion Risk.
Combustion Fume Risk.
Use vent run supports per installation instructions.
Connect vent sections per installation instructions.
•  Maintain all clearances to combustibles.
•  Do NOT allow vent to sag below connection 
point to appliance.
 •  Maintain specified slope (if required).
WARNING
Improper support may allow vent to sag or separate.
codes, and must not be easily blocked or obstructed, 
see Figure 4.4 on page 9. 
(3)   For installations requiring a vertical rise on the exterior 
of the building, a snorkel kit is available with a 14 in. 
(356mm) and a 36 in. (914mm) tall snorkel termination 
cap.  Follow the same installation procedures as used 
for standard horizontal terminations. If the  snorkel 
termination must be installed below grade (i.e. basement 
application), proper drainage must be provided to 
prevent water from entering the snorkel termination.  Do 
not backfill around snorkel termination.
