Mounting the Unit
NOTICE:
!
UNIT MUST BE INSTALLED IN A VERTICAL POSITION
WITH THE WATER FITTINGS POINTING UPWARD.
WARNING:
DO NOT INSTALL UNIT WHERE IT WOULD ROUTINE-
LY BE SPLASHED WITH WATER. ELECTRIC SHOCK
MAY RESULT.
CAUTION:
HOT WATER OUTLET PIPES LEAVING UNIT CAN BE
HOT TO THE TOUCH. INSULATION MUST BE USED
FOR HOT WATER PIPES BELOW A HEIGHT OF 36˝
DUE TO BURN RISK TO CHILDREN.
NOTICE:
!
THIS UNIT SHOULD NOT BE INSTALLED IN A LOCA-
TION WHERE IT MAY BE EXPOSED TO FREEZING
TEMPERATURES (LESS THAN 36 °F [2 °C]). IF THE
UNIT MAY BE SUBJECT TO FREEZING TEMPERA-
TURES, ALL WATER MUST BE DRAINED FROM THE
UNIT. FAILURE TO COMPLY WITH THIS INSTRUCTION
VOIDS ALL WARRANTIES.
THE UNIT SHOULD BE LOCATED IN AN AREA WHERE
WATER LEAKAGE FROM THE UNIT OR CONNECTIONS
WILL NOT RESULT IN DAMAGE TO THE AREA ADJA-
CENT TO THE UNIT. IF SUCH A LOCATION CANNOT
BE AVOIDED IT IS RECOMMENDED THAT A DRAIN
PAN BE INSTALLED UNDER THE UNIT.
1. Drill two (2) 1/4 inch holes in the wall where the
water heater will be mounted.
2. Install plastic wall anchors.
3. Fasten wall mounting bracket to the wall.
4. Hook water heater to the mounting bracket.
5. Pull downwards on the water heater to properly
seat it on the bracket.

Plumbing Connections
IMPORTANT:
!
IF WATER PIPES ARE OF COPPER OR BRONZE, USE
DIELECTRIC CONNECTIONS TO PREVENT HEATER
CORROSION. FAILURE TO PROVIDE DIELECTRIC IN-
SULATION MAY RESULT IN PREMATURE TANK OR
NIPPLE FAILURE AND MAY VOID YOUR WARRANTY.

NOTICE
:
!
HARD WATER OR WATER WITH A HIGH MINER-
AL COUNT MAY DAMAGE THE UNIT. DAMAGE TO
THE UNIT CAUSED BY SCALE OR A HIGH MINERAL
COUNT IS NOT COVERED UNDER THE WARRANTY.
CAUTION:
TO REDUCE THE RISK OF EXCESSIVE TEMPERATURE
AND PRESSURE IN THE WATER HEATER, A COM-
BINATION TEMPERATURE/PRESSURE (T&P) RELIEF
VALVE HAS BEEN INSTALLED.
CAUTION:
ALWAYS FILL THE UNIT'S TANK WITH WATER BE-
FORE PLUGGING THE WATER HEATER'S CORD INTO
AN ELECTRICAL OUTLET. FAILURE TO DO SO WILL
RESULT IN PERMANENT DAMAGE TO THE WATER
HEATER.
NOTICE:
!
WHEN A WATER HEATER IS INSTALLED IN A
CLOSED WATER-SUPPLY SYSTEM, SUCH AS ONE
HAVING A BACK-FLOW PREVENTER IN THE COLD-
WATER SUPPLY, MEANS SHALL BE PROVIDED TO
CONTROL THERMAL EXPANSION. CONTACT THE
WATER SUPPLIER OR LOCAL PLUMBING INSPECTOR
FOR INFORMATION REGARDING THE CONTROL OF
THIS SITUATION.
Connect the cold water pipe to the cold water connection on
the unit (blue). Connect the hot water pipe to the hot water
connection on the unit (red).
Ensure that the water heater is installed in a level position.
Install a shut-off on the cold water side of the water heater.
This is for emergency shut-off. It must be kept open when
the water heater is operating.
When using copper piping, solder a piece of tubing to a
threaded fitting (union) before screwing the adapter to the
tank.
BRAIDED FLEX HOSE CONNECTORS ARE ALSO RECOMMEND-
ED.
DO NOT APPLY HEAT DIRECTLY TO INLET OR OUTLET CON-
NECTIONS.
A certified T&P valve is mounted to the water heater by the
manufacturer with the outlet oriented to the right. If this
position needs to be changed, leakage may occur, especially
if it will be screwed counter-clockwise, and the T&P valve
may need to be resealed. After all plumbing work has been
completed, the T&P valve needs to be checked for proper
tightness.
During heating, the water volume and water pressure in-
creases in the tank. It is possible for water to leak from the
safety valve, this is normal.
