SIDEWALL TERMINATION – OPTIONAL CONCENTRIC
VENT: MODELS 150 - 600
DESCRIPTION AND USAGE
A. O. Smith offers optional concentric combustion air and vent
pipe termination kits (Factory Kit #100274637 for 3" diameter -
Models 150 - 200 and #100274638 for 4" diameter - Models 285
- 600). Both combustion air and vent pipes must attach to the
termination kit. The termination kits must terminate outside the
structure and must be installed as shown below in Figure 35.
The required combustion vent pipe materials are listed in Table
11, on Page 20 of this manual.

PREPARE WALL PENETRATIONS
1. Determine the best location for the termination kit (see Figure
above).
2. Reference the Determine Location section on Page 24 of this
manual for general termination considerations.
3. Cut one (1) hole (5 inch diameter for #100274637 installations
or 7 inch diameter for #100274638 installations) into the
structure to install the termination kit.
4. Partially assemble the concentric vent termination kit. Clean
and cement using the procedures found in these instructions.
