11.Push the vent cap/vent pipe assembly into the intake air Y fitting assembly until the vent cap seats properly on the large diameter intake air pipe. Ensure the vent pipe is cemented to the no stop-lip reducer bushing previously installed in the Y fitting. Secure the vent cap to intake air pipe with field supplied stainless steel screws. Install the screws through the pre-drilled holes in the vent cap brackets. Pilot holes for the screws must be drilled in the intake air pipe to prevent damage/cracking.

Assemble and install the 6 inch concentric termination. Refer to Figure 29, Figure 30 and Figure 31 for these instructions:

1.	Cement the Y fitting to the larger diameter intake air pipe.
2.	Cement the 6” x 4” no stop-lip reducer bushing into the

	straight (vent) end of the Y fitting.
3.	If the intake air piping being installed is 4 inch pipe, cement
	the 6” x 4” standard reducer bushing into the angle (intake
	air) end of the Y fitting as shown in Figure 29.
4.	If the intake air piping being installed is 6 inch pipe discard
	the 6” x 4” standard reducer bushing. The 6 inch intake air
	piping will connect directly to the angle end of the Y fitting.
5.	Slide the intake air Y fitting assembly from inside the building
	through the hole cut for the termination in the roof or sidewall.
	Ensure no foreign materials such as insulation accumulate
	inside the assembly.
6.	Secure the intake air Y fitting assembly using field supplied
	metal strapping or equivalent support materials.
7.	On installations installed through the roof slide a field supplied
	plumbing boot or roof flashing over the intake air Y fitting

8.	Seal around the plumbing boot or roof flashing.
9.	Slide the steel vent cap onto the 4 inch vent pipe and cement
	the vent terminal to the end of the vent pipe.
10.	Slide the vent cap back up the vent pipe until it touches the
	vent terminal. Secure the vent cap to the vent pipe using field
	supplied stainless steel screws. Pilot holes must be drilled
	for the screws to prevent damage/cracking of the vent pipe.
	Apply water proof silicone sealant between the vent cap and
	the terminal.
