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.Secure assembly to roof structure as shown in Figure 22 using field-supplied metal strapping or equivalent support material.

NOTICE

Ensure termination height is above the roof surface or anticipated snow level. Figure 22.

If assembly is too short to meet height requirements, the two pipes supplied in the kit may be replaced by using the same diameter pipe. DO NOT extend the overall dimension by more than 60 inches (152.4 cm). See Fig. 19.

7.Install rain cap and small diameter pipe assembly in roof penetration assembly. Ensure small diameter pipe is cemented and bottomed in Y concentric fitting.

8.Cement water heater combustion-air and vent pipes to concentric Y fitting assembly (Figure 20). See Figure 22 for proper pipe attachment.

9.Operate water heater through one cycle to ensure combustion-air and vent pipes are properly connected and sealed to concentric vent termination connections.

Horizontal Installation:

1.Become familiar with coaxial vent kit part no. 239-44069-01. As shown in Figures 19 through 21.

2.Determine the best location for the termination kit.
