Water connections should be in close orientation to the install site. Conrm there is
enough allowance for the water intake and outake hoses to reach the water heater.
Note: If your water pipes are copper or bronze be sure to use dielectric
connections to prevent corrosion. Failure to do so may cause damage to your
tank and void your warranty. In order to protect the water heater from heat
damage due to soldering, solder a piece of tubing to a threaded union tting
before screwing the union to the tank.
1. Install a shut o valve in line with the cold-water pipe.
2. Connect the cold water pipe to the inlet nipple, marked with a blue label.
3. Connect the hot water pipe to the outlet nipple, marked with a red label.

INSTALLATION
CLOSED SYSTEM THERMAL EXPANSION: Periodic discharge of the relief valve or
failure of the element gasket may be due to thermal expansion in a closed water
supply system. The water utility supply meter may contain a check valve, backow
preventer or water pressure-reducing valve that will create a closed water system.
During the heating cycle of the water heater, the heated water expands causing
pressure inside the water heater to increase. The T&P relief valve may discharge
hot water under these conditions that result in a loss of energy and a build up
of lime on the relief valve seat. To prevent this from happening, there are two
recommendations:
1. Install a diaphragm-type domestic hot water expansion tank (suitable for
potable water) on the cold water supply line. The expansion tank must have a
minimum capacity of 1.5 U.S. gallons for every 50 gallons of stored water.
2. Install a 125-PSI pressure relief valve in the cold water supply line. Make sure
the discharge of this valve is directed to an open drain and protected from
freezing.
Included with your water heater is a 3/4 inch temperature and pressure relief
(T&P valve) valve that is certied by a nationally recognized laboratory. This
is designed to reduce the risk of excessive pressures and temperatures in this
water heater and should be installed as directed by local codes. The T&P valve is
marked with a maximum pressure, which does not exceed the maximum working
pressure of the water heater (150 psi).
Note: If using a dierent temperature and pressure relief valve other than
the one provided with your purchase, please ensure that the maximum PSI
marking on the valve DOES NOT exceed the marked maximum working
pressure of the water heater.
1. Install the 3/4 inch T&P valve supplied with the water heater into the large
threaded opening located at the top of the water heater.
2. Attach a discharge pipe from the T&P valve terminating at a sink or drain. Do
not cap or plug the end of the dischage pipe.

MAINTENANCE
HOUSEKEEPING
When properly maintained, your water heater will provide years of dependable
trouble-free service. It is recommended that a periodic inspection of the pipe
connections be done every 6 months.
At least once a year, lift and release the lever handle on the pressure relief valve.
It is located between the hot and cold water lines and make certain the valve
operates freely. Allow several gallons to ush through the discharge line to an
open drain.
Inspect the area around the water heater to ensure a safe operating
environment. Keep the water heater area clear and free from any objects that
could damage the water heater. If damage or denting is present, contact a
service personnel to verify proper operation.
DO NOT operate the water heater if you feel something is wrong.
DO NOT allow children to operate or otherwise handle the water heater.
NOTICE! If the pressure relief valve on the hot water heater discharges
periodically, this may be due to a problem in the water system. Contact
the water supplier or your plumbing contractor on how to correct this. DO
NOT plug the relief valve outlet.
Maintenance
DRAINING AND STORAGE
Draining your water heater:
1. Unplug the water heater.
2. Open a hot water faucet to let hot water run out. Allow water to ow until
water is no longer hot.
3. Turn o the cold water supply to the water heater.
4. Close the hot water faucet.
5. Disconnect the water heater from both the hot and cold water connections.
6. If possible, siphon out any remaining water.
7. Carefully detach the water heater from the wall (if applicable).
8. Tilt the water heater to drain remaining water out of the heater.
NOTICE! When not being used for a lengthy period of time, you can
conserve energy by reducing the temperature setting either manually or
through the Eccotemp App.
Protect against freeze damage if you plan on not using the water heater for an
extended period of time. Unplug your water heater and drain.
