LOW-PROFILE VENT TERMINATION 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
.
Installation Code
1. Once the proper location has been determined, cut two holes
in the wall large enough to accommodate the pipe. See the
(page 34) for pipe diameters and distance between
Table 12
hole centers.
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
www.ipexinc.com.
3. To fasten the base to the wall, use the supplied screws and
anchors. A 3/16" (5 mm) hole, that is 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 the possibility of severe personal injury, death, or
substantial property damage.
7. Operate the heater through one heat cycle to ensure
combustion-air and vent pipes are properly connected to the
concentric vent termination.
