INSTALLATION
Electrical Connection
Ensure that the water heater is installed in a level po-
sition.
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 RECOM-
MENDED.
DO NOT APPLY HEAT DIRECTLY TO INLET OR OUTLET
CONNECTIONS.
A certified T&P valve is supplied with the water heat-
er and must be installed. 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
increases in the tank. It is possible for water to leak from
the safety valve, this is normal.

1. Temperature/Pressure relief valve
2. Hot water outlet
3. Cold water inlet
4. Discharge pipe
Install a discharge pipe from the relief valve terminating
at a sink or drain. Orient the tubing so that discharge
will exit within 6˝ (152 mm) above or at any distance
below the structural floor, and cannot contact any live
electrical parts.
DO NOT CAP OR THREAD THE END OF THE DISCHARGE
PIPE, IT MUST BE UNOBSTRUCTED AND FULL SIZE.
The T&P valve is certified by a nationally recognized
test laboratory that maintains periodic inspection of the
listed equipment, and meets the requirements for re-
lief valves and automatic shut-off devices for hot water
supply systems ANSI Z21.22.
The T&P valve is marked with a maximum pressure,
which does not exceed the maximum working pressure
of the water heater (150 PSI).
THE DISCHARGE PIPE
- Must not be smaller in size than the outlet pipe size
of the valve, or have reducing couplings.
- Must not be plugged or blocked.
- Must be of material suitable for hot water.
- Must not be over fifteen feet (15´) in length.
- Must not have more than two elbows.
- Must terminate at an adequate drain.
- Must not have a valve between the relief valve and
the tank.
9.1 Filling the Water Heater
To fill the water heater:
1. Open the hot water faucet.
2. Open the cold water supply valve.
3. When water runs out of the faucet, the tank is
filled.
4. Close the hot water faucet.
5. Check entire system for leaks.

!
CAUTION:
ALWAYS FILL THE UNIT’S TANK WITH WATER
BEFORE PLUGGING THE WATER HEATER’S CORD
INTO AN ELECTRICAL OUTLET. FAILURE TO DO
SO WILL RESULT IN PERMANENT DAMAGE TO
THE WATER HEATER.
NOTICE:
THE WATER HEATER MUST BE CONNECTED TO
A GROUNDED OUTLET.
THIS WATER HEATER WAS DESIGNED FOR
USE AT 110 - 120 V. DO NOT USE THIS WATER
HEATER WITH ANY OTHER VOLTAGE. FAILURE
TO USE THE CORRECT VOLTAGE MAY RESULT
IN PERSONAL INJURY OR PROPERTY DAMAGE.
THE HEATER IS SUPPLIED WITH AN ELECTRICAL
CABLE WITH A PLUG. IF THE CABLE IS DAM-
AGED OR LENGTH NOT SUFFICIENT, IT MUST BE
REPLACED BY A LICENSED ELECTRICIAN.
