Follow the instructions provided in your Owner’s
Packet for operation of the thermostat�
Water Heater
Safety
If your water system is full and cold, and the water
heater is ignited, the system can see pressures as
high as 120 PSI before the relief valve starts to open�
Since the water system normally operates in the
40-PSI range, the expanding water does put unusual
stress on the system� This normally does not cause
any problems, but the stress is easily alleviated� As the
water is heating, simply open any faucet and run as
little as a cup of water� Removing this small amount of
water will reduce the pressure buildup significantly.
NOTE
Review the water heater literature supplied in your
owner’s packet before proceeding.
WARNING
Hydrogen gas can be produced in a hot water
system served by this heater if it has not been
used for a long period of time (generally 2 weeks
or more). Hydrogen gas is extremely flammable. To
reduce the risk of injury under these conditions,
it is recommended that the hot water faucet be
opened for several minutes at the galley sink
before using any electrical appliance connected to
the hot water system. If hydrogen is present, there
will probably be an unusual sound heard such as
air escaping through the pipe as the water begins
to flow. Do not smoke or allow an open flame near
the faucet at the time it is open.
Electronic Ignition
The switch used to light your electronic ignition
water heater is located above the galley sink� When
the switch is turned on, the red light will come on,
indicating ignition mode� Normally, the burner will ignite
in just a few seconds, and the light will go out� If your
LPG system has not been used for some time, the
system may go into safety lockout (about 20 seconds)
before the air is all expelled from the lines� Turning the
switch off for 30 seconds, then back on, reinstates the
ignition mode�
