WARNING
: Hydrogen gas can be produced in a hot water
H
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 flammable.
To reduce the risk of injury under these conditions, it is recommended
that the hot water faucet he 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 such as air
escaping through the pipe as the water begins to flow. There should be no
smoking or 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 in the
bathroom above the lavatory top. When the switch is turned on, the red light
will come on indicating the "try" mode is in effect. Normally the burner will
ignite in just a few seconds, and the light will go out. If your LP system hasn't
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 "try" mode.
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 water ex-
panding 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 just
open any faucet and run as little as a cup of water. Just removing this small
amount of water reduces the pressure build up significantly.
For fun, watch the sequence of events your family goes through when you park
the trailer and ignite the water heater. More than likely someone will run water
and relieve the pressure without even realizing it.
