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 signicantly.
Electronic Ignition
The switch used to light your electronic ignition water
heater is located in the bathroom above the lavatory
top� Normally, the burner will ignite in just a few
seconds unless your LPG system has not been used
for some time and air may have lled the lines. The
system will go into safety lockout, after 3 failed ignition
attempts, before the air is expelled� If this happens the
red indicator light will come on� Turning the switch off
for 30 seconds and then back on reinstates the ignition
mode�
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 two weeks
or more). Hydrogen gas is extremely ammable. 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 ow. Do not smoke or allow an open ame near
the faucet at the time it is open.
