7 Installation
WARNING: PERSONAL INJURY, PROPERTY DAMAGE
This water heater should be installed in accordance with all
national, state and local codes and ordinances. If additional
information is desired, the latest edition of the National
Electric Code "NFPA 70" are recommended.
The above information is available from:
National Fire Protection Agency

Check with the local authorities having jurisdiction over your installation.
Before proceeding with the installation, close the main water supply
valve, open a water faucet to relieve the water pressure, and then close
the faucet.
This electric water heater is not intended for space heating applications.
7.1 Location
WARNING: FIRE, EXPLOSION
Areas where flammable liquids (gasoline, solvents, liquid
propane, butane, etc.), or other substances which emit
flammable vapors are stored may not be suitable for
water heater installation. Natural air movements can carry
flammable vapors varied distances from where they are
stored or used. The water heater thermostat contacts
can arc and ignite these vapors causing property damage,
serious burns or death. Never store or use flammable
substances in the same room or area containing an electric
water heater. Gasoline or other flammable substances must
never be used in the same room or area containing a water
heater or other spark-producing device.
This residential water heater should be installed in a clean, dry location close to
where a good electrical connection can be made and as close to the major usage of
hot water as possible. The unit can be installed on a combustible fl oor with
0 inches minimum clearance to combustible walls. The heater should be located so
that all electrical controls, heating elements, drain valve and water connections are
accessible. Adequate clearance must be provided for the access panel.
NOTICE: PROPERTY DAMAGE
This water heater must be located in an area where leakage
of the tank or connections will not result in damage to
the area adjacent to the water heater or to lower floors of
the structure. When such locations cannot be avoided,
a suitable drain pan must be installed under the water
heater. Such pans must be at least 2 inches deep having a
minimum length and width of at least 2 inches greater than
the diameter of the water heater and should be piped to an
adequate drain.
7.2 Condensation
Condensation can form on the tank when it is fi rst fi lled with water. Condensation
might also occur with a heavy water draw and very cold inlet water temperature.
This condition is not unusual and will evaporate after the water becomes heated. If,
however, the condensation continues, examine the piping and fi ttings for possible
leaks.
7.3 Water Lines and Connections
The hook-up connections will be determined by the need for hot water.
The cold water line connects to the inlet nipple at the base of the water
heater.
The hot water line connects to the outlet nipple on top of the water heater.
By providing unions on the water connections and a shut off valve in the
cold water line, the water heater may be disconnected for servicing when
necessary.
Two temperatures of hot water can be achieved by a mixing valve.
The valves, piping, and pipe connection should be of the same type and
manufacturer.
The pipe lengths from the center line of inlets and outlets to the water
heater must be exactly equal.
All hook-ups must comply with all local codes. Install a vacuum relief anti-
siphon device on the cold water inlet line.
Do not install a check valve or other devices that would prevent reverse
flow of water unless required by local codes because a closed system will
result and frequent operation of the relief valve will occur.
