9. Attach access door.
a. Snap hinge pin (FIG 3-C) into clip (FIG 3-D).
b. Slide cover (FIG 3-E) onto hinge pin.
c. Slide hinge pin into cover, snapping into clip at same time (FIG 3-D).
NOTE: To remove hinge pin, support access cover and apply force to
corner of hinge pin.
10. Disconnect unit and its individual shut-off valve from gas supply
line during any pressure testing of system in excess of 1/2 PSIG
(3.4 kPa, 14˝ water column [W.C.]).
DO NOT set inlet pressure higher
than maximum indicated on rating plate of gas valve (13˝ W.C.).
Isolate unit from gas supply line by closing its individual manual
shutoff valve during any pressure testing ≤ 1/2 psig.
ƽ WARNING
FIRE AND/OR EXPLOSION
•
DO NOT use matches, candles or other sources of ignition when
checking for gas leaks.
11. Turn on gas and check water heater and all connections for gas
leaks with leak detecting solution.
12. Fill water heater tank, check all connections for water leaks.
MIXING VALVE - (FIG 9)
ƽ WARNING
SCALDING INJURY
• Valve is not serviceable, it must be replaced.
• Replacement by a Certified Service Technician only.
• Tampering with valve will result in scalding injury.
• Tampering with valve will void warranty.
THIS VALVE IS A SAFETY COMPONENT AND MUST NOT BE REMOVED FOR ANY REASON
OTHER THAN REPLACEMENT. REMOVAL FOR REPLACEMENT BY A CERTIFIED SERVICE
TECHNICIAN ONLY
. The water heater is equipped with a mixing
(moderating) valve which mixes cold water with higher temperature
water to moderate outlet water to approximately 130˚F. It is also
equipped with a higher temperature thermostat, raising the storage
water temperature.
PRESSURE-TEMPERATURE RELIEF VALVE - (FIG 3-G)
ƽ WARNING
SCALDING INJURY
• Valve is not serviceable, it must be replaced.
• Tampering with valve will result in scalding injury.
• Tampering with valve will void warranty.
ƽ WARNING
EXPLOSION
•
DO NOT place a valve, plug or reducing coupling on outlet part of
pressure-temperature relief valve.
THIS VALVE IS A SAFETY COMPONENT AND MUST NOT BE REMOVED FOR ANY REASON
OTHER THAN REPLACEMENT.
This water heater is equipped with a
temperature and pressure relief valve that complies with the standard
for Relief Valves and Automatic Gas Shutoff Devices for Hot Water
Systems, ANSI Z21.22.
If you use a discharge line, do not use a reducing coupling or other
restriction smaller than outlet of relief valve. Allow complete drainage
of both valve and line.
FOR REPLACEMENT PARTS:
•
DO NOT install anything less than a combination temperature-pressure
relief valve certified by a nationally recognized testing laboratory that
maintains periodic inspection of product of listed equipment or
materials, as meeting requirements for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22.
Valve must have a maximum set pressure not to exceed 150 psi.
• Install valve into opening provided and marked for this purpose on
water heater.
• Installation must conform with local codes or in the absence of local
codes, American National Standard for Recreational Vehicles, ANSI
A119.2/NFPA 50IC.
• For an external electrical source, ground this unit in accordance with
National Electrical Code ANSI/NFPA70.

CONSUMER SAFETY WARNINGS
ƽ WARNING
EXPLOSION OR FIRE
• DO NOT store or use gasoline or other flammable vapors and liquids in
the vicinity of this or any other appliance.
• Should overheating occur, or gas supply fail to shut off, turn gas
OFF at the LP tank. On ELECTRONIC IGNITION MODEL turn operating
switch to OFF position and remove red wire from left hand terminal
of ECO switch or turn gas OFF at the LP tank.
• Use with LP gas only.
• Shut off gas appliances when refueling.
•
Turn gas OFF at the LP tank when vehicle is in motion. This disables
all gas appliances. Gas appliances must never be operated while
vehicle is in motion. Unpredictable wind currents may be created
which could cause flame reversal in the burner tube, which could
result in fire damage. The thermal cut off fuse could also be
unnecessarily activated resulting in a complete shutdown of the
water heater requiring replacement of the thermal cut off. See
maintenance of electronic ignition water heaters for further
explanation of the thermal cut off.
• LP tanks must be filled by a qualified gas supplier only.
HOW TO OPERATE YOUR WATER HEATER
ƽ CAUTION
FIRE
• Do not smoke or have any flame near an open faucet.
If water heater has not been used for more than two weeks, hydrogen
gas may form in water line. Under these conditions to reduce the risk
of injury, open hot water faucet for several minutes at kitchen sink
before you use any electrical appliance connected to hot water system.
If hydrogen gas is present, you will probably hear sounds like air
escaping through the pipe as water begins to flow.
ƽ WARNING
SCALDING INJURY
• Do not tamper with orifice or mixing valve.
ƽ CAUTION
PRODUCT FAILURE
• Do not operate without water in tank.
