diameter
hole for 4 in

vent termination, or 4 ½ in
(11.5 cm)
for 3 in
(7.6 cm)
vent termination.
4. Partially assemble vent kit.
a. Cement Y concentric fitting to larger diameter kit pipe (see Figure 20).
b. Cement rain cap to smaller diameter kit pipe (see Figure 21).
5. Install concentric Y fitting and pipe assembly
through the structure’s hole and field-supplied roof boot/flashing. Do
NOT
allow insulation or other materials to accumulate inside pipe assembly when installing through the hole.
6. Install rain cap and small diameter pipe assembly in concentric Y fitting and large pipe assembly. Ensure small
diameter pipe is cemented and bottomed in concentric Y fitting.
7. Secure assembly to structure as shown in Figure 23. Ensure clearances as shown in Figure 24.
8. Cement heater combustion-air and vent pipes to concentric Y fitting termination assembly. See Figure 24 for proper
pipe attachment.
9. Operate heater through one cycle to ensure combustion-air and vent pipes are properly connected and sealed to
concentric vent termination connections.
