EPJ SERIES INDIRECT WATER HEATERS – Installation and Service Manual
22
Service and Maintenance Section 7
The
EPJ Series Indirect Water Heater has been designed to provide years of trouble-free performance in
normal installations and requires minimal routine maintenance to ensure a safe and reliable supply of hot
water.
7.1 GENERAL OPERATION

DANGER: Before operating the T&P relief valve, make sure no person is near the T&P relief valve
discharge piping.

DANGER: Do not plug T&P relief valve or discharge piping. Plugging T&P relief valve or discharge
piping can cause excessive pressure in water heater resulting in severe personal injury, death or
substantial property damage.
 WARNING: This water heater may contain water at very high temperature and pressure. Wear
protective clothing, safety glasses and gloves. Ensure the water in the tank and coil has cooled to
room temperature before disconnecting fittings, piping or valves or opening the drain valve. Do not
solely rely on the pressure and temperature gauges to determine the temperature and pressure of
the water in the water heater.

If the temperature and pressure relief valve on the appliance discharges periodically, this may be
due to thermal expansion in a closed water supply system. Contact the water supplier or local
plumbing inspector for information on how to correct this situation. Do not plug the temperature and
pressure relief valve.

Hydrogen Sulfide gas can be produced in a hot water system that has not been used for a long
period of time (generally two weeks or more). Hydrogen Sulfide gas is extremely flammable. To
prevent the possibility of injury under these conditions, we recommend the hot water faucet to be
open for several minutes at the kitchen sink before you use any electrical appliance which is
connected to the hot water system. If hydrogen is present, there will probably be an unusual sound
such as air escaping through the pipe as the hot water begins to flow. There should be no smoking
or open flame near the faucet at the time it is opened.

Verify proper operation after servicing.
7.2
ELECTRONIC ANODE
 Most installations do not require the use of an anode, however, in extremely corrosive water
conditions, we recommend the use of an
Electronic Anode that is non-sacrificial (e.g.
“Corro-Protec”). A sacrificial anode, such as magnesium or aluminum, is not recommended and
may result in accelerated corrosion.
 The Electronic Anode should be installed in the top of the tank using the factory supplied kit. Please
contact the factory for details.

Follow the anode manufacturer’s instructions regarding installation and inspection to ensure
continuous and proper operation. The inspection should be performed annually but may need to
be more frequent in areas with water having low pH values or high hardness.
