heater's rating plate. Pressure rating of relief valve must not exceed
the working pressure shown on the rating plate of the heater and the
A.G.A hourly Btu rated temperature steam discharge capacity of the
relief valve shall not be less than the input rating of the heater. NO
VALVE IS TO BE PLACED BETWEEN THE RELIEF VALVE AND
TANK. DO NOT PLUG THE RELIEF VALVE.
The drain line connected to the valve must not contain a reducing
coupling or other restriction and should terminate near a suitable
drain to prevent water damage during valve operation. Discharge line
shall be installed to allow complete drainage of both the valve and
line. DO NOT THREAD, PLUG OR CAP THE END OF THE DRAIN
LINE.
IMPORTANT
• THIS HEATER MUST ONLY BE INSTALLED BY QUALIFIED
PERSONS IN ACCORDANCE WITH LOCAL PLUMBING AND
ELECTRICAL CODES. UNIT MUST BE INSTALLED INDOORS.
• THIS HEATER IS A PRESSURE VESSEL AND MUST HAVE A T
& P (TEMPERATURE & PRESSURE) VALVE INSTALLED (NOT
SUPPLIED).
• THIS HEATER IS AN ELECTRICAL DEVICE AND MUST BE
PROPERLY GROUNDED. FUSED AND CONNECTED TO THE
CORRECT LINE VOLTAGE.
• DO NOT OPERATE THE HEATER IN ROOMS, GARAGES OR
OTHER AREAS WHERE GASOLINE OR OTHER FLAMMABLE
LIQUIDS OR ENGINE DRIVEN VEHICLES OR EQUIPMENT ARE
STORED, OPERATED OR REPAIRED. FLAMMABLE VAPORS
ARE HEAVY AND TRAVEL ALONG THE FLOOR AND MAY BE
IGNITED BY THE ELECTRIC HEATER CAUSING FIRE OR
EXPLOSION.
• 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
• PROTECT HEATER FROM FREEZING, WATER LEFT IN THE
TANK AND ALLOWED TO FREEZE WILL EXPAND AND
DAMAGE THE TANK. DISCONNECT POWER AND DRAIN TANK
TO PREVENT DAMAGE.
• DO NOT ATTEMPT TO OPERATE THIS HEATER WITH THE
COLD WATER SHUTOFF VALVE CLOSED. DISCONNECT
POWER IF SHUTOFF VALVE IS CLOSED.
• TIGHTEN DRAIN SCREW BEFORE FILLING.
MOUNTING
A minimum clearance of 4" in front of the heater shall be allowed for
draining the tank and for access to replaceable parts such as the
thermostat, heater, and relief valve.
THE HEATER SHOULD BE LOCATED IN AN AREA WHERE
LEAKAGE OF THE TANK OR CONNECTIONS WILL NOT RESULT
IN DAMAGE TO THE AREA ADJACENT TO THE HEATER OR TO
LOWER FLOORS OF THE STRUCTURE. When such locations
cannot be avoided, a suitable drain pan piped to an adequate drain
should be installed under the heater. Drain pans suitable for these
heaters are available from your distributor.
FLOOD WARNING
IF THE HEATER BECOMES IMMERSED IN WATER, THE
HEATER SHOULD BE EXAMINED BY A COMPETENT SERVICE
PERSON BEFORE IT IS PLACED BACK IN OPERATION.
W-152 MOUNTING
The W-152 model is designed for wall or floor mounting, and
the heater should be located within 3-1
12
feet of a grounded
120V electrical outlet. Mount in an upright position only, with
the water connections at the top.
The model W-152 tank holds 2-1/
2
gallons and weighs 34
Ibs. when full. Make sure wall or cabinet is strong enough to
hold the weight of a full heater. Mount to wall stud or added
2x4.
Hold the tank in the position to be mounted and mark the top
and center of the tank on the wall. Measure down 1 -1
1/2
inch and mount the metal mounting bracket using two screws
provided. Hang the heater from the mounting bracket using
the two slots in the back of the tank jacket.
W-154 MOUNTING
The W-154 model is designed for floor mounting only, and
the heater should be located within 3-1
12
feet of a grounded
120V electrical outlet. Mount in an upright position only, with
the water connections at the top.
The W-154 model tank holds 4 gallons and weighs 45 Ibs.
when full. Make sure cabinet floor is strong enough to hold
the weight of a full heater.
To allow drainage of tank it is recommended that the water
heater be raised off the cabinet floor several inches using
suitable support blocks.
Do not connect the electrical power until the tank is full of water.
Failure to comply will burn out the heating element.
HYDROGEN GAS (FLAMMABLE)
HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER
SYSTEM SERVED BY THIS HEATER THAT HAS NOT BEEN
USED FOR A LONG PERIOD OF TIME (GENERALLY TWO
WEEKS OR MORE). HYDROGEN GAS IS EXTREMELY
FLAMMABLE.
To reduce the risk of injury under these conditions, it
is recommended that the hot water faucet connected to the hot water
system be opened for several minutes before using any electrical
appliance. If hydrogen is present, there will probably be an unusual
sound such as air escaping through the pipe as the water begins to
flow. THERE SHOULD BE NO SMOKING OR OPEN FLAME NEAR
THE FAUCET AT THE TIME IT IS OPEN.
WATER CONNECTIONS
The cold water inlet is identified by a blue label. A dip tube is
supplied to carry cold water from the tank top to the bottom. Be sure
that it is in the cold water inlet. Connect the cold water line to the
1
12"
N PT female fitting on the top of the heater (use teflon tape on
threaded connections).
The hot water outlet is identified by a red label. Connect the hot
water line to the 1 /2" NPT female fitting on the top of the tank (use
teflon tape on threaded connections). Grip the tank fittings with
wrench to minimize stress.
NOTE: THIS IS A BRONZE TANK, WHEN CONNECTING TO
GALVANIZED PIPE, ALWAYS USE A DIELECTRIC UNION TO
REDUCE CORROSION DUE TO GALVANIC ACTION BETWEEN
DISSIMILAR METALS.
