WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long period
of time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive. To prevent the pos-
sibility of injury under these conditions, we recommend
the hot water faucet be opened for several minutes at the
kitchen sink before any electrical appliances which are
connected to the hot water system are used (such as a
dishwasher or washing machine). If hydrogen gas is pre-
sent, there will probably be an unusual sound similar to
air escaping through the pipe as the hot water faucet is
opened. There must be no smoking or open flame near
the faucet at the time it is open.
HIGH TEMPERATURE LIMIT SWITCH
(Single-Use Type Energy Cut Off)
The thermostat has a built-in limit switch which will actuate
in case of excessive water temperatures. The heater cannot
be relit until the gas control valve is replaced. It is important
that a serviceman be called to determine the reason for limit
operation and thus avoid repeated thermostat replacement.
Lower the temperature adjustment setting on new control.
NOT ENOUGH OR NO HOT WATER
1. Check the manual gas shut off valve to be sure it is open.
2. The ON/OFF switch on the control box must be “ON”.
3. The temperature button adjustment may be set too low.
See the “Temperature Regulation” section.
4. The gas company can check the gas input to see if it is
correct. An underfired water heater will not heat water as
quickly.
5. Look for leaking or open hot water faucet’s. Make sure
all are closed.
6. The cold water inlet temperature may be colder during
the winter months. It will take longer to heat the water
and seem like less hot water.
7. If you cannot find what is wrong, call the local gas util-
ity and/or plumbing contractor.
WATER IS TOO HOT
1. The temperature adjustment setting may be set too high.
See the “Temperature Regulation” section.
NOTE: A period of time is necessary after an adjust-
ment has been made for the water temperature to
reach the new temperature setting.
2. If lower temperature settings will not lower the water
temperature, call the local gas utility.
WARNING
Should overheating occur or the gas supply fail to shut
off, turn “off” the manual gas control valve to the
appliance.
