Vent/Flue Pipe Terminations

■ The vent/flue pipe may terminate vertically, as through a roof,

or horizontally, as through an outside wall.

■ Vertical vent/flue pipe terminations should be as shown in

“Vertical Vent Termination (Single Pipe)” illustration. Refer to

“Termination Locations” in this section for details concerning

location restrictions.

■ The penetration of the vent through the roof must be sealed

tight with proper flashing such as is used with a plastic

plumbing vent.

■ Horizontal vent/flue pipe terminations should be as shown in

“Horizontal Vent Termination (Single Pipe)” illustration. Refer

to “Termination Locations” in this section for details

concerning location restrictions.

■ A 2³⁄₈" (6.1 cm) diameter wall penetration is required for 2"

(5.1 cm) diameter pipe.

■ A 3" (7.6 cm) diameter hole is required for a 2¹⁄₂" (6.4 cm)

pipe.

■ A 3¹⁄₂" (8.9 cm) diameter hole is required for 3" (7.6 cm)

diameter pipe.

■ To secure the pipe passing through the wall and prohibit

damage to the piping connections, a coupling should be

installed on either side of the wall and solvent cemented to a

length of pipe connecting the 2 couplings.

■ The length of pipe should be the wall thickness plus the

depth of the socket fittings to be installed on the inside and

outside of the wall.

■ The wall penetration should be sealed with silicone caulking

material.

■ In a basement installation, the vent/flue pipe can be run

between joist spaces.

NOTE: If the vent pipe must go below a joist and then up into

the last joist space to penetrate the header, two 45° elbows

should be used to reach the header rather than two 90°

elbows.
