HIGH TEMPERATURE LIMIT SWITCH
(Single-Use Type Energy Cut Off)
The thermostat has a built-in limit switch which will actu-
ate in case of excessive water temperatures. The heater can-
not be relit until the gas control valve is replaced. It is
important that a serviceman be called to determine the rea-
son 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.
For Your Information (cont’d)
SMELLY WATER (cont’d)
If the smelly water persists after the anode replacement and
chlorination treatment, we can only suggest that continuous
chlorination and filtering conditioning equipment be con-
sidered to eliminate the water problem.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater tank is voided.

VENTING MANUAL RESET SWITCH
There is a venting manual reset switch located on the draft
hood. If the venting manual reset switch is activated, it will
not reset itself. Before resetting this venting manual reset
switch, check for flue blockage and propriety of the venting
system. To reset the venting manual reset switch, press the
red reset button.

WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long peri-
od of time (generally two weeks or more). Hydrogen gas
is extremely flammable and explosive. To prevent the
possibility of injury under these conditions, we recom-
mend 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
present, 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.
WARNING
Should overheating occur or the gas supply fail to shut
off, turn “off” the manual gas control valve to the
appliance.
