32 Installing the Water Heater
●
Do not store hazardous or flammable substances
near the vent termination.
●
If this water heater will be installed in areas where
snow is known to accumulate, protect the vent
termination from 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.
●
Vent pipes must be supported at least every 4
ft (1.2 m) horizontally and every 6 ft (1.83 m)
vertically.
WARNING
●
The vent piece connected to the water heater
must be secured by one self-tapping screw.
Securing screw
●
Each pipe must be secured using two self-tapping
screws when connecting extension pipes or
the elbow to the vent piece. When inserting the
screws, ensure that you place the screws at a point
1.0 in (25 mm) from the vent pipe end to avoid
damaging the vent pipe gasket.

Ensure that the self-tapping screws are used to
secure the pipes together as well as the pipes
to the water heater. Failure to do so may result
in the pipes being loose and thereby cause
property damage, personal injury, or death.
