3) Venter (Flue) Outlet Venter Outlet Attachment Requirements:

Depending on the size of vent

pipe as determined in Require-

ment 2), attach either the vent

pipe directly to the venter col-

lar or a taper-type enlarger.

4) Joints and Sealing

Provide eld-supplied vent pipe as specied in Requirement No. 1.

• If using single wall, 26-gauge or heavier galvanized pipe, secure slip-t

connections using sheetmetal screws or rivets. Seal pipe joints either with

tape suitable for 550°F (such as Option FA1, P/N 98266) or high-tempera-

ture silicone sealant.

• If using Category III vent pipe, follow pipe manufacturer’s instructions for

joining pipe sections. When attaching Category III pipe to the venter outlet

or the vent cap, make secure, sealed joints following a procedure that best

suits the style of Category III pipe being used.

• If installing a double-wall (Type B) terminal pipe, follow the instructions

in FIGURE 10C to join the double-wall pipe to a single-wall or Category III

vent pipe run. To attach the vent cap, follow instructions in FIGURE 10B.

• If using double-wall (Type B) vent pipe in the vent pipe run (at least 75%

of the equivalent vent length must be vertical), follow the pipe manufactur-

er’s instructions for joining pipe sections. For attaching double-wall pipe to

the heater, see FIGURE 10A. To attach the vent cap, see FIGURE 10B.

A double-wall

pipe run is

allowed only if

at least 75% of

the vent length is

vertical.

Figure 10A - STEP 1

To secure the connection,

spaced equal distance

around the pipe, drill and

insert three 3/4” long sheet-

metal screws through the

pipe and into the collar. Do

not over tighten the screws.
