Follow instructions in Requirement No. 4. below to make the connection for the type of pipe being used.

4) Joints and Sealing

Provide field-supplied vent pipe as specified in Requirement No. 1.

 

• If using single wall, 26-gauge or heavier galvanized pipe, secure slip-fit connec-

 

tions using sheetmetal screws or rivets. Seal pipe joints either with tape suitable for

 

550°F (such as Option FA1, P/N 98266) or high-temperature silicone sealant.

 

• If using Category III vent pipe, follow pipe manufacturer's instructions for join-

 

ing 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 FIG-

 

URE 17C 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 17B.

 

• 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 manufacturer's instruc-

 

tions for joining pipe sections. For attaching double-wall pipe to the heater, see

 

FIGURE 17A. To attach the vent cap, see FIGURE 17B.

FIGURE 17A - Attaching Double- Wall (Type-B) Vent Pipe to the Venter Outlet

A double-wall pipe run is allowed only if at least 75% of the vent length is vertical.

To secure the connection, spaced equal distance around the pipe, drill and insert three 3/4” long sheetmetal screws through the pipe and into the collar. Do not over tighten the screws.

Fill inside the pipe, around the collar, with silicone sealant being sure there are no gaps.

FIGURE 17B - Attaching Double-Wall (Type B) Pipe to a Vent Cap

Figure 17B - STEP 1

Place a continual 3/8” bead of silicone sealant around the circumference of the vent cap collar. This will prevent any water inside the vent cap from running down the double-wall pipe.

Do STEP 2 immediately following STEP 1.

Figure 17B - STEP 2

Insert the collar on the vent cap inside the inner wall of the double-wall pipe. Insert as far as possible. Add additional silicone sealant to fully close any gaps between the vent cap and the double-wall pipe. This is necessary to prevent water from entering the double-wall pipe.

Figure 17B - STEP 3

Secure the vent cap to the double-wall pipe by drilling and inserting a

3/4” long sheetmetal screw into the vent cap collar. Do not over tighten screw.
