CIRCULATING PUMP
A circulating pump is used when a system requires a circulating loop or
there is a storage tank used in conjunction with the heater. Refer to the
piping diagrams at rear of manual for electrical hookup information and
install in accordance with the current edition of the National Electrical
Code ANSI/NFPA No. 70.
Only all bronze circulating pumps are used with commercial water
heaters. Although circulators are oiled and operated by the manufacturer
some circulators must be oiled again before operating. Please refer to
manufacturer’s instructions.
INSTALLATION INSTRUCTIONS
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES
ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE
FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING, ELECTRICAL
AND GAS SUPPLY WORK ARE REQUIRED.
LOCATING THE HEATER
WARNING
THERE IS A RISK IN USING FUEL BURNING APPLIANCES SUCH AS
GAS WATER HEATERS IN ROOMS, GARAGES OR OTHER AREAS
WHERE GASOLINE, OTHER FLAMMABLE LIQUIDS OR ENGINE
DRIVEN EQUIPMENT OR VEHICLES ARE STORED, OPERATED
OR REPAIRED. FLAMMABLE VAPORS ARE HEAVY AND TRAVEL
ALONG THE FLOOR AND MAY BE IGNITED BY THE HEATER’S
PILOT OR MAIN BURNER FLAMES CAUSING FIRE OR EXPLOSION.
SOME LOCAL CODES PERMIT OPERATION OF GAS APPLIANCES
IF INSTALLED 18 INCHES (45.7 CM) OR MORE ABOVE THE FLOOR.
THIS MAY REDUCE THE RISK IF LOCATION IN SUCH AN AREA
CANNOT BE AVOIDED.
DO NOT INSTALL THIS WATER HEATER DIRECTLY ON A CARPETED
FLOOR. A FIRE HAZARD MAY RESULT.
Instead the water heater must
be placed on a metal or wood panel extending beyond the full width
and depth by at least 3 inches (7.6 cm) in any direction. If the heater is
installed in a carpeted alcove or closet, the entire fl oor shall be covered
by the panel. Also, see the drain requirements.
THE WATER SUPPLY PRESSURE SHOULD NOT EXCEED 80 PSI
(551.58 kPa). IF THIS OCCURS, A PRESSURE REDUCING VALVE
WITH A BYPASS SHOULD BE PLACED ON THE SUPPLY TO THE
ENTIRE HOUSE IN ORDER TO MAINTAIN EQUAL HOT AND COLD
WATER PRESSURES.
THIS HEATER SHALL BE LOCATED OR PROTECTED SO IT IS NOT
SUBJECT TO PHYSICAL DAMAGE BY A MOVING VEHICLE.
WARNING
FLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANY OTHER
POTENTIAL FIRE HAZARDOUS ARTICLES MUST NEVER BE PLACED
ON OR ADJACENT TO THE HEATER. OPEN CONTAINERS OF
FLAMMABLE MATERIAL SHOULD NOT BE STORED OR USED IN
THE SAME ROOM WITH THE HEATER.
When installing the heater, consideration must be given to proper
location. Location selected should be as close to the stack or chimney
as practicable, with adequate air supply and as centralized with the
piping system as possible.
THE HEATER MUST NOT BE LOCATED IN AN AREA WHERE IT WILL
BE SUBJECT TO FREEZING.
THE HEATER SHOULD BE LOCATED IN AN AREA WHERE LEAKAGE
FROM THE HEATER OR CONNECTIONS WILL NOT RESULT IN
DAMAGE TO THE ADJACENT AREA OR TO LOWER FLOORS OF
THE STRUCTURE.
WHEN SUCH LOCATIONS CANNOT BE AVOIDED, A SUITABLE
DRAIN PAN SHOULD BE INSTALLED UNDER THE HEATER. Such
pans should be fabricated with sides at least 2" (5cm) deep, with length
and width at least 2" (5cm) greater than the diameter of the heater
and must be piped to an adequate drain. The pan must not restrict
combustion air fl ow.
Drain pans suitable for these heaters are available from your distributor
or Water Heater Parts Fulfi llment, 125 Southeast Parkway, Franklin,
TN 37068.
For appliance installation locations with elevations above 7700 feet
(610 meters), refer to HIGH ALTITUDE INSTALLATIONS section of this
manual for input reduction procedure.
CLEARANCES
These heaters are approved for installation on combustible fl ooring in a
closet having a ceiling 12" (30.5cm) above top cover and with clearances
to combustible construction of 6" (15.2cm) from fl ue or vent connector, 0"
(0cm) at the sides and rear and 5" (10.2cm) to front to prevent a possible
fi re hazard condition. A minimum of 4" (10.2cm) shall be allowed for
installation of serviceable parts.
HARD WATER
Where hard water conditions exist, water softening or the threshold type
of water treatment is recommended. This will protect the dishwashers,
coffee urns, water heaters, water piping and other equipment.
See MAINTENANCE section for details of tank cleanout procedure.
AIR REQUIREMENTS
REFER TO THE CURRENT EDITION OF THE "NATIONAL FUEL GAS
CODE ANSI Z223.1/NFPA 54.
KEEP APPLIANCE AREA CLEAR AND FREE OF COMBUSTIBLE
MATERIALS, GASOLINE AND OTHER FLAMMABLES, VAPORS AND
LIQUIDS.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION OR VENTILATING
AIR.
WARNING
ATTIC AND/OR EXHAUST FANS OPERATING ON THE PREMISES
WITH A WATER HEATER CAN RESULT IN CARBON MONOXIDE
POISONING AND DEATH.
OPERATION OF THESE FANS CAN PRODUCE A NEGATIVE DRAFT IN
THE AREA OF THE WATER HEATER PREVENTING THE PRODUCTS
OF COMBUSTION FROM EXHAUSTING THROUGH THE CHIMNEY
OR VENT PIPE.
The venting of the water heater should be inspected by a qualifi ed service
technician at the time of installation and periodically thereafter to ensure
a down-draft condition does not exist.
WARNING
FOR SAFE OPERATION PROVIDE ADEQUATE AIR FOR COMBUSTION
AND VENTILATION. AN INSUFFICIENT SUPPLY OF AIR WILL CAUSE
RECIRCULATION OF COMBUSTION PRODUCTS RESULTING IN
AIR CONTAMINATION THAT MAY BE HAZARDOUS TO LIFE. SUCH
A CONDITION OFTEN WILL RESULT IN A YELLOW, LUMINOUS
BURNER FLAME, CAUSING CARBONING OR SOOTING OF THE
COMBUSTION CHAMBER, BURNERS AND FLUE TUBES AND
CREATES A RISK OF ASPHYXIATION.
