Venting the Water Heater - Overview
DO NOT
use primer or cement on the appliance connection.
The products covered in this manual are designed for 2 in. vent pipes. Both vent pipes can be
installed without an external adapter. When installing the vent pipe, please refer to the
following pages for selection & installation of the correct vent piping for your application.
• Covering non-metallic vent pipe and fittings with thermal insulation is prohibited.

Rubber gasket
Flue pipe
Vent collar
•
Ensure the ends of the vent pipe are properly beveled to 90° prior to installation. Also ensure the
pipe is fully connected to the exhaust gas vent fitting. Failure to properly bevel and install the
pipe correctly could lead to gasket failure and flue gas leakage, which could result in serious
injury or death.
Connecting the Pipe to the Vent Collar
Vent Pipe Installation
1. Measure 1.8 in (45 mm) from the end of the vent pipe and
then draw a mark at that distance.
2. Insert the pipe into the vent collar to start the vent run. Make
sure to completely slide the vent into the collar until the end
makes contact with the bottom of the socket. (See Fig. 13.1)
3. Verify that 1.8 inches of the pipe has been completely
inserted into the collar and that the mark is no longer visible.
The pipe will be tightened and sealed by the rubber gasket.
Vent Termination Guidelines:
DO NOT
store hazardous material or flammable substances near the vent termination.
• To avoid moisture and frost build-up and to maintain clearances on adjacent homes, 45° & 90°
elbows and tees may be attached to the end of the termination vent pipe to direct the
exhaust plumes away from buildings. However, the total allowable vent lengths, maximum
number of elbows, and distances to air intake restrictions must be observed.
• If this water heater will be installed in areas where snow is known to accumulate, protect the
vent termination blockage.
• Ensure that the vent termination is at least 12 in (305 mm) above the highest anticipated
snow line, or as required by local codes, whichever is greater.
• Support the vent pipe with hangers at regular intervals, or as required by local codes.
• Exhaust and intake air pipes must be supported at least every 4 ft (1.2 m).
• The vent for this appliance shall not terminate over public walkways, near soffit vents or
crawlspace vents, where condensate or vapor could create a nuisance, hazard, or cause
property damage. Nor where condensate or vapor could cause damage or could be
detrimental to the operation of regulators, relief valves, or other equipment.
DO NOT
start the vent run with a
street elbow at the vent collar.
Using an elbow directly at the collar
will not allow for a tight seal
between the appliance and the vent
pipe. A section of straight pipe must
be used when starting the vent run.
WARNING
If the connections leak, harmful gas could cause
severe personal injury or death. After completing
the installation, and the unit is filled with water,
turn on the water heater and test it for leaks using
a bubble test kit. After applying the soap solution,
bubbles will form on the connections if leaks exist.
