Reliance Water Heaters 184123-000 - Manual (Page 20)

HIGH TEMPERATURE SHUT OFF SYSTEM
This water heater is equipped with an automatic gas shut
off system. The high temperature shut off is built into the
gas control valve. This system shuts off the gas supply to
the water heater burners when high water temperatures
are present. It is non-resettable. If the high temperature
shut off activates, the gas control valve must be replaced.
If this were to occur, turn “OFF” the entire gas supply to
the water heater. Contact the local gas utility.
NOT ENOUGH OR NO HOT WATER
1. Check the manual gas shut off valve to be sure it is
open.
2. Check the pilot flame. It may have gone out. All mod-
els have an opening behind the outer door for viewing
the pilot.
3. If the pilot is not lit, follow the “Lighting” instructions
in this manual or located above the gas control valve
on the water heater to relight the pilot. If the water was
extremely hot and is now cold, the high limit safety
temperature shut off may have put out the burner and
pilot. If the high temperature shut off activates, the gas
control valve must be replaced.
4. The gas control knob must be turned to the “ON”
position.
5. The temperature adjustment dial may be set too low.
See the “Temperature Regulation” section.
6. The gas company can check the gas input to see if it is
correct. An underfired water heater will not heat water
as quickly.
7. Look for leaking or open hot water faucets. Make sure
all are closed.
8. 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.
9. If you cannot find what is wrong, call the local gas
utility and/or plumbing contractor.
WATER IS TOO HOT
1. The temperature adjustment dial may be set too high.
See the “Temperature Adjustment” 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 con-
tinuous chlorination and filtering conditioning equipment
be considered 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.
“AIR” IN HOT WATER FAUCETS
20
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 min-
utes 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.
