Installing the Vent Termination

Roof Terminations

A roof termination of any type will require a 4-in. (102 mm)

flashing for a 2

−

in. (50 mm ND) concentric vent or a 5

−

in. (127

mm) diameter flashing for a 3-in. (80 mm ND) concentric vent

kit. For two-pipe or single pipe vent systems, a flashing for each

pipe of the required diameter will be necessary.
It is recommended that the flashing be installed by a roofer or

competent professional prior to installing the concentric vent.

The terminations can be installed on a flat or pitched roof.

Concentric Vent

Single or multiple concentric vent must be installed as shown in

Figure 49

. Maintain the required separation distance between

vents or pairs of vents as shown in

Figure 49

and all

clearance shown in

Figure 60

WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal

NOTICE

RECOMMENDED SUPPORT FOR VENT

TERMINATIONS

It is recommended that rooftop vent terminations in

excess of 36 inches (1.0 M) in vertical length be

supported by EITHER the Direct Vent Termination Kit

shown in

Table 12

or by field-supplied brackets or

supports fastened to the structure.

Cut the required number of holes in the roof or sidewall for vent

and (when used) combustion air pipes. Sidewall holes for

two-pipe vent terminations should be side-by-side, allowing

space between the pipes for the elbows to fit on the pipes.
Holes in the roof for direct

−

vent (two

−

pipe) terminations should

be spaced no more than 18

−

in. (457 mm) apart to help avoid

vent gas recirculation into combustion air intake.
Termination elbows will be installed after the vent and (if used)

combustion air pipe is installed.

Sidewall Terminations

Concentric Vent

NOTE

: Follow the instructions of the vent terminal

manufacturer. These instructions are provided as a reference,
only.
Determine an appropriate location for termination kit using the
guidelines provided in section “Locating The Vent Termination”

in this instruction.

1. Cut one 4

−

in. diameter hole for 2

−

in. kit, or one 5

2. Loosely assemble concentric vent/combustion air

termination components together using instructions in kit.

3. Slide assembled kit with rain shield REMOVED through

hole.

NOTE

: Do not allow insulation or other materials to accumulate

inside of pipe assembly when installing it through hole.

4. Locate assembly through sidewall with rain shield

positioned no more than 1

−

in. (25 mm) from wall as

shown in

Figure 49

5. Disassemble loose pipe fittings. Clean and cement using

same procedures as used for system piping. DO NOT

CEMENT POLYPROPYLENE FITTINGS.
