Eccotemp EM-2.5 Installation And Operating Instruction Manual - Plumbing Connections
PLUMBING CONNECTIONS
Connect the cold water inlet pipe to the inlet nipple (marked with a blue
ring) and the hot water outlet pipe to the outlet nipple (marked with a
red ring).
IMPORTANT: If Water pipes are copper or bronze, use dielectric
connections to prevent corrosion. Failure to provide dielectric insulation
may result in premature tank or nipple failure and may void your
warranty. Insure that the water heater is installed in a level position.
Install a shut off valve on the cold water side of the water heater.
The valve is for servicing and the valve should be in the open position
when the water heater is in operation. In order to protect the water
heater from heat damage due to soldering, solder a piece of tubing to a
threaded UNION fitting before screwing the UNION to the tank.
DO NOT APPLY HEAT DIRECTLY TO INLET OR OUTLET CONNECTIONS.
TEMPERATURE AND PRESSURE RELIEF VALVE:
CAUTION!: Install the Temperature/Pressure Relief Valve supplied with
the water heater!
Install a discharge pipe from the temperature/pressure relief valve
terminating at a sink or drain. DO NOT CAP OR PLUG THE END OF THE
DISCHARGE PIPE. THE DISCHARGE PIPE MUST BE UNOBSTRUCTED AND
FULL SIZED.
The T/P valve is certified by a nationally recognized test lab that
maintains periodic inspections of the listed equipment and meets the
requirements for relief valves and automatic shut off devices for hot
water supply systems ANSI 121.22-1979.
The T/P valve is marked with a maximum pressure, which does not
exceed the maximum working pressure of the water heater (150 PSI).
Install the T/P valve into the threaded opening at the top of the water
heater and orient the discharge tubing so that any discharge from
the valve will exit within 6 inches above, or at any distance below the
structural floor, and cannot contact any live electrical part.
