I. Install Metal Roof Flashing

• See minimum vent heights for various pitched roofs

(Figure 10.16) to determine the length of pipe to extend

through the roof.

• Slide the roof flashing over the pipe sections extending

through the roof as shown in Figure 10.17.

Figure 10.16 Minimum Height From Roof To Lowest Discharge

Opening

NOTICE: Failure to properly caulk the roof flashing could

cause water entry.
• Caulk the gap between the roof flashing and the outside

diameter of the pipe.

• Caulk the perimeter of the flashing where it contacts the

roof surface. See Figure 10.17.

CAUTION! Risk of Fire! Follow the requirements of the

local standards and codes for minimum height require-

ments from roof line.

Important Notice: Heat shields may not be field constructed.

H. Heat Shield Requirements for Horizontal

Termination

WARNING! Risk of Fire! To prevent overheating and fire,

heat shields must extend through the entire wall thick-

ness.

DO NOT remove the heat shields attached to the

wall shield firestop and the horizontal termination cap

(shown in Figure 10.14).

• Heat shields must overlap 1-1/2 in. (38 mm) mini-

mum.

There are two sections of the heat shield. One section

is factory-attached to the wall shield firestop. The other

section is factory-attached to the cap. See Figure 10.14.
If the wall thickness does not allow the required 1-1/2 in.

(38 mm) heat shield overlap when installed, an extended

heat shield must be used.
• If the wall thickness is less than or 4-3/8 in. (111 mm),

the heat shields on the cap and wall shield firestop

must be trimmed. A minimum 1-1/2 in. (38 mm) overlap

MUST be maintained.

• Use an extended heat shield if the finished wall

thickness is greater than 7-1/4 in. (184 mm).

• The extended heat shield may need to be cut to length

maintaining sufficient length for a 1-1/2 in. (38 mm)

overlap between heat shields.

• Attach the extended heat shield to either of the existing

heat shields using the screws supplied with the extended

heat shield. Refer to vent components diagrams in the

back of this manual.

• Rest the small leg on the extended heat shield on top

of the pipe section to properly space it from the pipe

section.
