GENERAL INFORMATION
This water heater must be installed in accordance with The Federal
Manufactured Home Construction And Safety Standard (H.U.D. Title 24, Part
3280.707d2) or CAN/CSA Z240 MH series, mobile home. In the absence of
such a standard, the water heater should be installed in accordance with the
Standard For Mobile Homes (ANSI/NFPA NO. 501-B1977).
The warranty for this water heater is in effect only when the water heater is
installed, adjusted, and operated in accordance with these Installation and
Operating Instructions. The manufacturer will not be liable for any damage
resulting from alteration and/or failure to comply with these instructions.
This water heater is of the closed combustion type (direct venting) where all the
combustion air is supplied from the outdoors through the air intake and all
combusted gas products are vented directly to the outside by means of the roof
jack. No draft diverter (vent hood) is required for this water heater.
INTERTEK has tested a representative sample of this water heater design for
its safety of operation. The ETL listing of this water heater includes the field
installation of the following components: roof jack, air intake tube, and heater
tie down materials. These components for field installation may have been
shipped with this heater and must be installed according to these instructions
(see figure 1). No other components are approved for use with this water
heater.
This water heater has been designed and certified for the purpose of heating
potable water. The installation and use of this water heater for any purpose
other than the heating of potable water may cause damage to the water heater,
create a hazardous condition, and nullify the warranty.
Do not use this appliance if any external part to the tank has been submerged
in water. You should contact a qualified service technician to inspect the
appliance and to replace any part of the control system including the
combination gas control which has been submerged in water. See the Gas
Connections section of this manual before servicing or replacing a water heater
that has had any external part to the tank submerged in water.
CAUTION
Incorrect operation of this appliance may create a hazard to life and
property and will nullify the warranty.
WARNING
Prior to connecting the gas supply line to a gas fired water heater,
ensure that the gas supply line does not have moisture/water or
dirt/scale inside the gas line. Commonly this check is done at the
lowest point in the gas distribution system prior to gas burning
appliances.

General Information continued-
This water heater has been manufactured for operation at altitudes from sea
level to 2000 feet (610m) (unless otherwise specified on the water heater).
For use of this appliance at an elevation greater than 2000 feet (610m), contact
the dealer or manufacturer listed on the rating plate for information on any
necessary modification. Uncorrected operation of this appliance may create a
hazard to life and property.
Make sure to check the rating plate and combination gas control on the water
heater to be certain that the type of gas being supplied corresponds with the
marking on the rating plate and combination gas control.
A sacrificial anode(s) is used to extend tank life. Removal of any anode, except
for inspection and/or replacement, will nullify the warranty. In areas where
water is unusually active, an odor may occur at the hot water faucet due to a
reaction between the sacrificial anode and impurities in the water. If this should
happen, an alternative anode(s) may be purchased from the supplier that
installed this water heater. This will minimize the odor while protecting the tank.
Additionally, the water heater should be flushed with appropriate dissolvers to
eliminate any bacteria.
INSTALLATION
Locating the Water Heater
This water heater MUST NOT be installed in any location where gasoline or
flammable vapors are likely to be present, unless the installation is such to
eliminate the probable ignition of gasoline or flammable vapors.
The location of this water heater is of the utmost importance. Before installing this
water heater, read the Installation section of these instructions. DO NOT locate the
water heater where water lines could be subjected to freezing temperatures.
Make sure the cold water pipes are not located directly above the gas control
so that condensate during humid weather does not drip on the controls.
IMPORTANT
Before proceeding, please inspect the water heater and components for
possible damage. DO NOT install any damaged components. If damage
is evident then please contact the supplier where the water heater was
purchased or the manufacturer listed on the rating plate for replacement
parts.
DANGER
Do not store or use gasoline or other flammable, combustible, or
corrosive vapors and liquids in the vicinity of this or any other
appliance.
