incidents arising or resulting from the use of external
insulation blankets. The manufacturer will not be liable for
corrosion of parts which may have resulted from the use of
such insulation blankets.
(1) The space between the base and the floor on a gas water
heater is necessary for proper air flow. This space must be
maintained unobstructed. As time passes, the blanket may sag
causing an obstruction of this air passage, resulting in an
unsafe operating condition.
(2) Do not apply insulation to the top of a gas water heater.
This will affect the operation of the draft hood, resulting in an
unsafe operating condition.
(3) Do not cover any access panels leading to burner
compartments, thermostat(s) control, doors, or temperature
&pressure relief valve on the water heater.
(4) Do not cover any labels or instruction material applied to
this water heater. These safety labels and instruction material
must remain on the water heater and be visible for reference by
the user. Do not attempt to remove these labels, as they are a
permanent part of this water heater as required by Certification
Agencies and/or the Federal Government.
INSTALLATION CHECK LIST*
*This is presented for ease of reference. It is not comprehensive.
All instructions and warnings must be read and adhered to.
A. HEATER LOCATION
Close to area of vent.
Indoors and protected from freezing temperatures.
(Refer to Water Piping Section)
Proper clearance from combustible surfaces observed and
heater not installed directly on carpeted floor.
Sufficient fresh air supply for proper operation of heater.
Air supply free of corrosive elements and flammable
vapors.
Provisions made to protect area from water damage.
Sufficient room to service heater.
B. WATER SUPPLY (See WATER PIPING)
Install a cold water inlet valve (Figure 6).
Heater completely filled with water.
Water connection tight and free of leaks.
C. RELIEF VALVE
Install a new Temperature and Pressure Relief Valve
properly and discharge line run to open drain.
Discharge line protected from freezing (Figure 6).
D. GAS SUPPLY
Gas supply same as the type of gas listed on the data plate.
Gas line equipped with shut-off valve, union and drip leg
(Figure 6).
Approved pipe joint compound used.
Soap and water solution used to check all connections and
fittings for possible gas leaks.
E. VENTING (Figure 6)
Draft diverter properly installed.
Vent connector(s) securely fastened together with screws.
Vent connector(s) at least 6” from combustible material.
Flue baffle engaged in slots if provided in flue tube.
heater fittings as they may contain nonmetallic parts. When
making these connections, always use a good grade of pipe
joint compound and be certain that all fittings are drawn up
tight (See Figure 6 for proper installation).
After piping has been installed allow tank to fill with water
and check connections for leaks. To insure complete filling of
the tank, allow air to exit by opening the nearest hot water
faucet until a constant flow of water is obtained.
CAUTION
OPERATING AN EMPTY OR PARTIALLY FILLED WATER
HEATER WILL RESULT IN DAMAGE TO THE TANK.
SOLAR INSTALLATION
When this appliance is used AS A SOLAR STORAGE
HEATER OR AS A BACKUP FOR THE SOLAR SYSTEM,
the following warning applies.
WARNING
Water supply to this heater
must not exceed 180°F. Water temperature in excess of 180°F
will cause the high limit control to function or open and shut
off gas supply. The high limit control is a single use type that
will require the replacement of the thermostat before the burner
can operate. If the water supply from the solar system is above
120°F, a tempering valve or temperature limiting valves must
be installed in the water supply line to limit the supply
temperature to 120°F .
CHEMICAL VAPOR CORROSION
The water heater should not be installed near an air supply
containing halogenated hydrocarbons. Water heater corrosion
and component failure can be caused by the heating and
breakdown of airborne chemical vapors. Beauty shops, dry
cleaning establishments, photo processing labs, storage areas
of liquid and powdered bleaches, swimming pool chemicals,
spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, calcium and sodium chloride, waxes
and process chemicals are typical locations and compounds
which are potentially corrosive. These materials are corrosive
at very low concentration levels with little or not odor to
reveal their presence. Products of this sort should not be stored
near the water heater. Air which is brought in contact with the
water heater should not contain any of these chemicals. If
necessary, uncontaminated air should be obtained from remote
or outside sources. NOTE: Contaminated air may cause and
orange colored flame.
INSULATION BLANKET
CAUTION
Insulation blanket kits which are available for external appli-
cations to water heaters are not recommended. However, some
governing bodies require their use in new construction of
additions, regardless of how efficient the water heater may be.
If an insulation blanket is applied to this heater CAUTION
must be exercised not to restrict the proper function of the
heater. The manufacturer of this heater will not be liable for
