Assemble and install the 6 inch concentric termination. Refer to
Figure 25, Figure 26 and Figure 27 for these instructions:
1. Cement the Y tting to the larger diameter intake air pipe.
2. Slide the intake air pipe and Y tting 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.
3. Secure the intake air Y tting assembly using eld supplied
metal strapping or equivalent support materials.
4. On installations installed through the roof slide a eld
supplied plumbing boot or roof ashing over the intake air Y
tting assembly and secure it to the roof.
5. Seal around the plumbing boot or roof ashing.
6. Cement the vent cap onto the vent pipe. Alternately a eld-
supplied stainless steel screw may be used to secure the 2
components together when eld disassembly is desired for
cleaning. A pilot hole must be drilled for the screw to prevent
damage/cracking of the vent cap and/or vent pipe.
7. Install the vent cap/vent pipe assembly into the intake air Y
tting assembly, Ensure small diameter vent pipe is cemented
and bottomed in the Y tting.
8. Connect the intake air and vent piping from the water heater
to the 6 inch concentric termination using eld supplied 6” x
4” reducer couplings as needed.
9. Return to Direct Vent Installation on page 23 to complete
the installation of the intake air and vent piping between the
concentric termination and the water heater.
