switch or breaker to corresponding colored wires in heater junction box. A
green wire from a well grounded source must be attached to the green ground
screw or nut in the junction box.
CAUTION: Before applying the 120 VAC power to the water heater junction
box, be sure the switch for electric element is in the “OFF” position.
WARNING!
Before the switch for the electric element is turned to the “ON” position, the
water heater tank must be filled with water. See “Safety Warnings”.
MAKING WATER CONNECTIONS
A.
Water connections are made at the rear of the water heater. See Figure 6.
Connect the hot and cold water lines to the 1/2” female pipe fitting provided
on rear of tank. These fittings are marked “HOT” and “COLD”. NOTE: Inside
each fitting is a plastic fill tube. Its purpose is to enhance water circulation.
DO
NOT REMOVE PLASTIC FILL TUBE.
IMPORTANT:
Use a pipe thread compound suitable for potable water or pipe
thread tape on all connections to assure they will not leak.
B.
For ease of removal, it is suggested that a pipe union be installed in each
water line.
C.
Fill tank with water. Open both hot and cold water faucets to expel air from
tank. When tank is filled and water flows from faucets, close both faucets and
check all connections for leaks.
CAUTION: If you use air pressure to check for leaks, the pressure must not
exceed 30 PSI (in accordance with NFPA 1192).
NOTE:
After leak testing, drain water from tank.
MAKING GAS CONNECTIONS
A.
Connect a 3/8” gas supply line to the 3/8 flare fitting at gas valve located in the
control housing. When making the gas connection, hold the gas fitting on the
valve with a wrench when tightening the flare nut. Failure to hold fitting secure
could result in a gas leak due to fitting being damaged.
NOTE:
It will be necessary to remove the grommet from the control housing, make
the gas connection at the valve, then reinstall grommet.
WARNING!
It is imperative that grommet and gas line through grommet be caulked air
tight. If not tightly sealed, moisture and potential harmful flue products could vent through
opening and into living area of trailer. (See Figure 7.)
B.
Turn on gas and check all fittings and connections for leaks, using a soap and
water solution. Correct even the slightest leak immediately.
WARNING!
Do not use an open flame to check for leaks!

OPERATING INSTRUCTIONS
– Electric Elements –
Electric water heaters are designed to
operate with a minimum amount of service
problems; however, proper operation and
care is essential.
By far the most common trouble with
electric water heaters results from
energizing the water heater before it is
filled with water. Even brief operation of
the electric element without water in the
tank will burn-out the electric heating
element.
Before the electric element will operate,
the switch located behind the water heater
door in the lower left corner of the control
housing must be in the “ON” position.
To energize the electric element, locate
the Switch, Lamp and Plate assembly
(see Figure 8) inside the RV and turn the
switch marked “ELECTRIC” to the “ON”
position. The water heater temperature
will be regulated by the thermostat.
