Operating The Electronic Control - Dometic WH-6GA Manuel D'installation Et D'utilisation

L.P. Gas Water Heater
• Gas appliances must never be operated while the
vehicle is in motion. Unpredictable wind currents
may be created which could cause flame reversal in
the burner tub, 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.

CAUTION: FIRE HAZARD.
Do not smoke or have any flame near an open
faucet. Failure to obey this caution could result in
minor or moderate injury.

CAUTION: EXPLOSION HAZARD.
If water heater has not been used for more than two
weeks, hydrogen gas may form in the water line.
Under these conditions, to reduce the risk of injury,
open the hot water faucet for several minutes at the
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.
Failure to obey this warning could result in death or
serious injury.
NOTICE: Do not operate without water in tank, product
failure can occur.

5.1.1 Gas Function

WARNING: BURN HAZARD, FIRE,
EXPLOSION, AND/OR CARBON MONOXIDE
HAZARD.
Keep the water heater area clear of combustible
cleaning materials, gasoline, and other flammable
vapors and liquids. Failure to obey this warning
could result in death or serious injury.
When the gas heating element switch is turned to
the ON position, the Water Heater will make three
attempts to light. If for any reason there is no ignition,
the Water Heater will lockout and the red lockout lamp
will illuminate. If the thermostat fails, the E.C.O. will also
lockout the Water Heater and a reset will be required.
Determine the reason for no control, correct it, and reset
the gas control sequence by turning the switch to the
OFF position then to the ON position.
5.1.2 Electric Heating Element
When the electric element switch is turned to the ON
position, the relay will close and pass 110 VAC to the
element. If the thermostat fails, the E.C.O. will open and
lockout the system. To correct, check the thermostat to
assure good contact with the tank. Reset the control by
turning the electric switch to the OFF position then to
the ON position.
5.1.3 Gas/Electric Function
The unit can be run in both gas and electronic modes
simultaneously for a quick recovery.
I If the gas fails to ignite, the gas mode will lockout,
but the lockout lamp will not illuminate since the
electric mode is still operational.
Should you notice slow recovery, indicating the gas is
not working, turn the electronic control switch to the
OFF position. The indicator lamp will illuminate signaling
a lockout has occurred on the gas side.
Correct the problem and turn the switches to the ON
position.
