Installation Manual
2 Installation
1. Ensure all items listed in Section 1.1 are complete.
2. Common installation practice is to determine the
termination and exterior wall penetration point first.
Next, design the venting/intake piping layout back to
the heater. Keep in mind, centrally locating the water
heater, whenever possible, is recommended to keep hot
water distribution times even thoughout the structure.
3. To determine the appropriate penetration point, refer to
the allowable termination clearances listed in Figure 7.
4. Once penetration point is determined, use a 5" hole saw
with proper blade (depending on wall construction) to
cut hole for kit installation.
5. Insert Item 2 (Fig. 1) through exterior wall from the
outside until flange is flush with wall surface. Ensure
that combustion air openings on Item 2 face toward the
ground as shown in Fig. 6. Secure flange to exterior wall
with screws provided.
6. Connect item 1 to item 2 (Fig. 1) from inside the
structure. The air intake connection opening (Item 1)
can be turned to best suit the connection of the intake
pipe. Secure both items with machine screws provided.
7. Locate end clamps on concentric kit (Fig. 3, step 1).
Open clamps as shown in Figure 3, step 2.

8. Insert vent piping through the concentric vent kit. Close
end clamps around vent pipe (Fig. 4, step 3). Secure
clamps by inserting screws where shown (Fig. 4, step 4).

9. On the outside of the structure, connect tee terminal to
exhaust vent pipe (Fig. 5). Be sure to maintain 12"
clearance from exterior wall to tee terminal as indicated
in Figure 6.
