AIR REQUIREMENTS
For safe operation an adequate supply of fresh,
uncontaminated air must be provided for combustion.
This gas-
fi
red water heater is a direct vent model. It
connects directly to the outside of the building through
the vent termination hood. The hood operates as both
the combustion air intake and the heater exhaust port
(see Figure 16).
All combustion air is obtained from outside the building
through this hood. Ensure the area around the termination
hood is always kept clear and that the air supply is not
exposed to contamination or
fl
ammable vapo rs.
CONFINED SPACE INSTALLATIONS
This water heater connects to the vent termination hood
using the sealed air intake and exhaust piping (see Figure
1 and Figure 2).
During operation this piping can become hot, especially in
areas experiencing high ambient temperatures.
When installed in a con
fi
ned space such as a closet, it is
recommended that the con
fi
ned space be ventilated to
minimize the buildup of heat around the heater. Figure 6
and Figure 7 show an examples of ventilating a con
fi
ned
space.

Clearances To Combustibles
Minimum clearances between water heater and
combustibles are 0” at the sides and rear, 5.5” from the
front and 12” from top. Minimum clearances from vent
piping to combustibles is 1” except as noted in Figure
21. If clearances stated on the heater differ from these
clearances, install water heater according to clearances
stated on the heater (see Figure 6).
Floors With Carpeting
This water heater must not be installed directly on
carpeting. Carpeting must be protected by a metal or
wood panel beneath the appliance extending beyond
the full width and depth of the appliance by at least 3” in
every direction, or if the appliance is installed in an alcove
or closet, the entire
fl
oor must be covered by the panel.
Failure to heed this warning may result in a
fi
re hazard.
Clearance For Servicing
Adequate clearance of 24” for servicing this appliance
should be considered before installation, such as changing
the anodes, etc.
A minimum clearance of 5.5” must be allowed for access
to replaceable parts such as thermostats, drain valve and
relief valve.
When installing the heater, consideration must be given to
proper location. Location selected should be as close to
the wall as practicable and as centralized with the water
piping system as possible.
CHEMICAL VAPO R CORROSION
CORROSION OF THE FLUEWAYS AND VENT SYSTEM
MAY OCCUR IF AIR FOR COMBUSTION CONTAINS
CERTAIN CHEMICAL VAPO RS. SUCH CORROSION
MAY RESULT IN FAILURE AND RISK OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and
air conditioning refrigerants, swimming pool chemicals,
calcium and sodium chloride (water softener salt), waxes,
and process chemicals are typical compounds which are
potentially corrosive. Do not store products of this sort
near the heater or the vent termination hood. Air which is
brought in contact with the heater or the vent termination
hood should not contain any of the chemicals. The Limited
Warranty is voided when failure of water heater is due
to a corrosive atmosphere. See “Limited Warranty” for
complete terms and conditions.
Read instruction manual before
installing, using or servicing
water heater.
•
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this water heater, the vent termina-
tion hood, or any other appliance.
•
Avoid all ignition sources if you smell gas.
•
Do not expose water heater control to excessive gas
pressure.
•
Use only gas shown on rating plate.
•
Maintain required clearances to combustibles.
•
Keep ignition sources away from faucets after extended
period of non-use.
