Figure 15 - Rain Cap to Small Vent Pipe Assembly
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 16 using field-
supplied metal strapping or equivalent support material.
Figure 16 - Concentric Vent Roof Top Attachment
Install rain cap and small diameter pipe assembly in roof penetration
assembly. Ensure small diameter pipe is cemented and bottomed in Y
concentric fitting.
Cement heater combustion-air and vent pipes to concentric y fitting
assembly (Figure 13). See Figure 16 for proper pipe attachment.
Operate heater through one cycle to ensure combustion-air and vent
pipes are properly connected and sealed to concentric vent termination
connections.

NOTICE Ensure termination height is above the roof surface or antici-
pated snow level. Figure 16.
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.
See Fig. 15.
Horizontal Installation:
1. Become familiar with coaxial vent kit part no. SP20261 for CAN &
US. As shown in Figures 14 through 16.
2. Determine the best location for the termination kit.
