Low Profile Termination Installation - American Water Heater 300 Series Instruction Manual

LOW PROFILE 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 codes or the current editions of the National Fuel Gas Code
(ANSI Z223.1/NFPA 54) or the Natural Gas and Propane Installation
Code (CAN/CSA B149.1).
1. Once the proper location has been determined, cut 2 holes in the
wall large enough to accomodate the pipe. Pipe diameters and
distance between hole centers can be found in Table 9.
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" (5mm) hole, 1-3/16" (30mm) 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.
8. Operate heater through 1 heat cycle to ensure combustion-air and
vent pipes are properly connected to concentric vent termination
connections.
