GETTING STARTED
This water heater uses a non-direct,
single-pipe vent system to remove
exhaust gases created by the burning
of fossil fuels. Air for combus on
is taken from the immediate water
heater loca on or is ducted in from
the outside (see Enclosure InstallaƟ on
Requirements).
This water heater must be properly
vented for the removal of exhaust
gases to the outside atmosphere.
Correct installa on of the vent pipe
system is mandatory for the proper
and effi cient opera on of this water
heater and is an important factor in the
life of the unit.
The vent pipe must be installed
according to all local and state codes
or, in the absence of local and state
codes, the NaƟ onal Fuel Gas Code,
ANSI Z223.1 (NFPA 54)-current edi on.
Manufactured home manufacturers
must conform with The Manufactured
Home ConstrucƟ on and Safety
Standard, Title 24 CFR, Part 3280.
The vent pipe installa on must not
be obstructed so as to prevent the
removal of exhaust gases to the
outside atmosphere.
IMPORTANT:
• Do not use a vent damper anywhere
in the vent system of this water
heater.
• DO not common vent this water
heater with any other appliance.
• This water heater must have a
properly-installed dra hood and be
connected to a listed roof jack that
terminates to the outdoors. The
roof jack vent pipe must be secured
to the dra hood with sheet metal
screws. (Roof jack not furnished.)
The following roof jack models are
cer fi ed for use with this water heater
