NOTE:
The use of cellular core PVC (ASTM F891), cellular core
CPVC, or Radel® (polyphenolsulfone) in non-metallic venting
systems is prohibited. Covering non-metallic vent pipe and fittings
with thermal insulation is prohibited. If the water heater is being
installed as a replacement for an existing power vented heater
in pre-existing venting, a thorough inspection of existing venting
system must be performed prior to any installation work. Verify
that correct material as detailed above has been used, and that
the minimum or maximum vent lengths and terminal location as
detailed in this manual have been met. Carefully inspect the entire
venting system for any signs of cracks or fractures, particularly at
joints between elbows and other fittings and straight runs of vent
pipe. Check system for signs of sagging or other stresses in joints
as a result of misalignment of any components in the system.
If any of these conditions are found, they must be corrected in
accordance with the venting instructions in this manual before
completing installation and putting the water heater into service.
NOTE: For water heaters in locations with high ambient
temperatures above 100°F (38°C) it is recommended that CPVC
or Polypropylene pipe and fittings be used.
NOTE:
Use only solid (not foam core) piping. Plastic pipe and
fittings are available through most plumbing suppliers. Always
check the marking on the pipe to make sure you are using the
correct material.
POLYPROPYLENE INSTALLATIONS
The water heater has been approved to be installed with
Polypropylene vent material as shown in Table 5 and Table
6. The approved application of single wall, non-flexible, non-
concentric Polypropylene vent material is offered by two specific
manufacturers (Centrotherm ECO Systems and DuraVent
Polypropylene). These listed products must be installed by following
the vent manufacturer’s instructions. Refer to Table 7 in Planning
the Vent System on Page 24 to determine the maximum pipe length
and number of elbows that can be used.
Insulation should not be used on Polypropylene venting materials.
The use of insulation will cause increased vent wall temperatures,
which could result in vent pipe failure.
Use only the adapters and vent system listed in Tables 5 and 6.
DO NOT mix vent systems of different types or manufacturers.
Failure to comply could result in severe personal injury, death, or
substantial property damage.
Installations must comply with applicable national, state, and
local codes. For Canadian installation, Polypropylene vent must
be listed as a ULC-S636 approved system. If Polypropylene vent
is not required by your local code, you may use either PVC or
CPVC pipes for your water heater that allows non-metallic venting
material installations.
Polypropylene vent systems do not use cement to connect the pipe
and elbow sections but use a push together gasket seal method.
Do not attempt to connect Polypropylene with sealant cement. All
vent connections MUST be secured by the vent manufacturer’s
joint connector. The installer must use a specific vent starter
adapter at the flue connection. The adapter is supplied by the vent
manufacturer to adapt to its vent system.
In order to be in full compliance with UL 1738 or ULC-S636 and
to meet the requirements of the water heater manufacturer, you
must use the metal joint connector rings, available from the
Polypropylene vent manufacturer, to stiffen the joints of 2”, and
3” diameter pipes.
VENT PIPE TERMINATION
The first step is to determine where the inlet and exhaust vent
pipes will terminate. The combustion air inlet and exhaust outlet
piping and terminations may be installed in one of the following
termination types:
1.
Standard Horizontal (2 Pipe) - See Figure 24
2. Alternate Horizontal (2 Pipe) - See Figure 20
3. Vertical (2 Pipe) - See Figures 21, 22, & 25
4. Concentric Vent Through the Wall - See Figure 30
5. Concentric Vent Through the Roof - See Figure 29
When venting one water heater, locate the inlet and exhaust
terminations according to Figure 11 below. When installing more
than one water heater, see Venting Multiple Units on Page 30.

Figure 11.
The vent system must terminate so that proper clearances are
maintained as cited in local codes or the current edition of the
National Fuel Gas Code, (ANSI Z223.1, 12.9.1 through 12.9.4) or
the Natural Gas and Propane Installation Code (CAN/CSA-B149.1).
See Figure 23.
Instructions on proper installation through a sidewall are provided in
Figure 18 and Figure 19. Plan the vent system layout so that proper
clearances are maintained from plumbing and wiring.
Vent pipes serving power vented water heaters are classified by
building codes as vent connectors. Required clearances from
combustible materials must be provided in accordance with
information in this manual under Locating The Water Heater on Page
15 and Installation Requirements starting on Page 17, and with the
National Fuel Gas Code and local codes.
PLANNING THE VENT SYSTEM
For water heater installations at elevations up to 2000 ft (610 m),
size the exhaust and combustion air inlet pipes as specified in
Table 7A. For water heater installations at elevations from 2000
ft (610 m) to 7,700 ft (2,347 m), size the exhaust and combustion
air inlet pipes as specified in Table 7B. Tables 7A and 7B list
the maximum allowable length in feet of the exhaust outlet and
combustion air inlet pipes as related to the number of required
elbows and the termination type. The specified maximum lengths
are for the separate inlet and exhaust pipe systems and not the
combined length of both systems. The minimum pipe length is 6
feet with one elbow per side.
