CAUTION
: Hydrogen gas can be produced in a hot water system served by this heater that 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 kitchen 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.
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 expanding 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.
