MULTIPLE CONCENTRIC VENT TERMINATION
When two concentric vent kits are being installed, the vent hood
centers shall be either less than 240 mm (9.5”) apart
or
more than 1.1
m (43.5”) apart. Spacings between 240 mm (9.5”) and 1.1 m (43.5”)
are not allowed due to the possibility of exhaust cross circulation
(see Figure 25).
When more than 2 kits are installed only 2 of them shall be less than
240 mm (9.5”) apart. Never install 3 termination kits together less
than 240 mm (9.5”) apart (see Figure 26).

LOW PROFILE VENT INSTALLATION
This water heater is certified for sidewall direct venting with IPEX
System 636 Low Profile Vent Kit. Follow instructions below for proper
installations.
All termination kits must be located and installed in accordance with
local building code and
CSA B149.1 Natural Gas and Propane Installation
Code
.
1.
Once the proper location has been determined, cut 2 holes in
the wall large enough to accommodate the pipe. Pipe diameters
and distance between hole centers can be found in
Table 12
(page 24).
2.
Slide both the intake and exhaust pipes through the holes.
Solvent cement both pipes to the base of the vent termination
kit, follow the solvent cementing procedures outlined in the IPEX
System 636 Installation Guide, which is available on the web
www.ipexinc.com.
3.
To fasten the Base to the wall, use the supplied screws and
anchors. A 3/16” (5 mm) hole, 1-3/16” (30 mm) deep, will need
to be drilled for the anchors. Locate the anchor hole using the
base as a template.
4.
Screw the Cap to the Base using the supplied screws.
5.
Once the vent termination and pipes are secured, the wall
penetrations will need to be sealed from the interior using a PVC-
compatible sealant material.
6.
All vent pipes and air inlets must terminate at the same height to
avoid possibility of severe personal injury, death, or substantial
property damage.
7.
Operate heater through 1 heat cycle to ensure combustion-air and
vent pipes are properly connected to concentric vent termination
