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 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.
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 indicat-
ing 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 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.
