WATER PIPING
WARNING
HOTTER WATER CAN SCALD: WATER HEATERS ARE INTENDED TO
PRODUCE HOT WATER. WATER HEATED TO A TEMPERATURE WHICH
WILL SATISFY CLOTHES WASHING, DISH WASHING, AND OTHER
SANITIZING NEEDS CAN SCALD AND PERMANENTLY INJURE YOU
UPON CONTACT. SOME PEOPLE ARE MORE LIKELY TO BE
PERMANENTLY INJURED BY HOT WATER THAN OTHERS. THESE
INCLUDE THE ELDERLY, CHILDREN, THE INFIRM, OR PHYSICALLY/
MENTALLY HANDICAPPED. IF ANYONE USING HOT WATER IN YOUR
HOME FITS INTO ONE OF THESE GROUPS OR IF THERE IS A LOCAL
CODE OR STATE LAW REQUIRING A CERTAIN TEMPERATURE WATER
AT THE HOT WATER TAP, THEN YOU MUST TAKE SPECIAL
PRECAUTIONS. IN ADDITION TO USING THE LOWEST POSSIBLE
TEMPERATURE SETTING THAT SATISFIES YOUR HOT WATER NEEDS,
A MEANS SUCH AS A MIXING VALVE, SHOULD BE USED AT THE
HOT WATER TAPS USED BY THESE PEOPLE OR AT THE WATER
HEATER. MIXING VALVES ARE AVAILABLE AT PLUMBING SUPPLY
OR HARDWARE STORES. FOLLOW MANUFACTURERS
INSTRUCTIONS FOR INSTALLATION OF THE VALVES. BEFORE
CHANGING THE FACTORY SETTING ON THE THERMOSTAT, READ
THE "TEMPERATURE REGULATION" SECTION IN THIS MANUAL.
This water heater shall not be connected to any heating systems or
component(s) used with a non-potable water heating appliance.
If a water heater is installed in a closed water supply system, such as
one having a back-flow preventer, check valve, water meter with
check valve, etc... in the cold water supply, means shall be provided
to control thermal expansion. Contact the water supplier or plumbing
contractor on how to control this situation.
NOTE: To protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that dielectric
unions or couplings be installed on this water heater when
connected to copper pipe.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the cold water inlet connection.
Do not solder the cold water supply line directly to the cold
water inlet. It will harm the dip tube and damage the tank.
WARNING
IF A WATER HEATER IS INSTALLED IN CONJUNCTION WITH A
SEPARATE STORAGE VESSEL, THE STORAGE VESSEL MUST ALSO
BE EQUIPPED WITH A TEMPERATURE-PRESSURE RELIEF VALVE
COMPLYING WITH THE STANDARD FOR RELIEF VALVES AND HOT
WATER SUPPLY SYSTEMS, ANSI Z21.22. THE HOURLY RATED
TEMPERATURE STEAM BTU DISCHARGE CAPACITY OF THE
TEMPERATURE-PRESSURE RELIEF VALVE(S) SHALL NOT BE LESS
THAN THE COMBINED BTU INPUT TO THE WATER HEATER(S)
SUPPLYING WATER TO THE STORAGE VESSEL(S).
THERMOMETERS (Not Supplied)
Thermometers should be obtained and field installed as shown in the
installation diagrams.
Thermometers are installed in the system as a means of detecting the
temperature of the water in the appliance.
TEMPERATURE-PRESSURE RELIEF VALVE
This water heater is equipped with a combination temperature-pressure
relief valve that complies with the standard for relief valves and automatic
gas shutoff devices for hot water supply system, ANSI Z21.22. FOR
SAFE OPERATION OF THE WATER HEATER, THE RELIEF VALVE(S)
MUST NOT BE REMOVED OR PLUGGED.
ASME ratings cover pressure relief capacities. A.G.A. ratings cover
release rate with temperature actuation.
In addition to the appliance relief valve, each remote storage tank which
may be used in conjunction with this appliance shall also be installed with
a properly sized, rated and approved combination temperature (ANSI)
and pressure (ASME) relief valve(s).
WARNING
THE PURPOSE OF RELIEF VALVE IS TO AVOID EXCESSIVE
PRESSURE OR TEMPERATURE INTO THE STEAM RANGE, WHICH
MAY CAUSE SCALDING AT FIXTURES, TANK EXPLOSION, SYSTEM
OR HEATER DAMAGE. NO VALVE IS TO BE PLACED BETWEEN THE
RELIEF VALVE AND TANK.
Your local code authority may have other specific relief valve
requirements.
A DRAIN LINE MUST BE CONNECTED TO THE RELIEF VALVE TO
DIRECT DISCHARGE TO A SAFE LOCATION TO AVOID SCALDING
OR WATER DAMAGE. THIS LINE MUST NOT BE REDUCED FROM
THE SIZE OF THE VALVE OUTLET AND MUST NOT CONTAIN VALVES
OR RESTRICTIONS NOR SHOULD IT BE LOCATED IN FREEZING
AREAS. DO NOT THREAD OR CAP THE END OF THIS LINE.
RESTRICTED OR BLOCKED DISCHARGE WILL DEFEAT THE PURPOSE
OF THE VALVE AND IS UNSAFE. DISCHARGE LINE SHALL BE
INSTALLED TO ALLOW COMPLETE DRAINAGE OF BOTH THE VALVE
AND LINE.
See SERVICE INFORMATION section for procedure and
precautions.
WARNING
THE TEMPERATURE-PRESSURE RELIEF VALVE MUST BE MANUALLY
OPERATED AT LEAST ONCE A YEAR. CAUTION SHOULD BE TAKEN
TO ENSURE THAT (1) NO ONE IS IN FRONT OF OR AROUND THE
OUTLET OF THE TEMPERATURE-PRESSURE RELIEF VALVE
DISCHARGE LINE, AND (2) THE WATER MANUALLY DISCHARGED
WILL NOT CAUSE ANY BODILY INJURY OR PROPERTY DAMAGE
BECAUSE THE WATER MAY BE EXTREMELY HOT.
IF AFTER MANUALLY OPERATING THE VALVE, IT FAILS TO
COMPLETELY RESET AND CONTINUES TO RELEASE WATER,
IMMEDIATELY CLOSE THE COLD WATER INLET TO THE WATER
HEATER, FOLLOW THE DRAINING INSTRUCTIONS, AND REPLACE
THE TEMPERATURE -PRESSURE RELIEF VALVE WITH A NEW ONE.
