A. Water Heater Location
❑ Close to area of heated water demand.
❑ Indoors and protected from freezing temperatures.
❑ Area free of flammable vapors.
❑ Provisions made to protect area from water damage.
❑ Sufficient room to service water heater.
B. Water Supply
❑ Water heater completely filled with water.
❑ Water heater and piping air vented.
❑ Water collector openings not in use are plugged tight.
❑ Water connections tight and free of leaks.
C. Relief Valve
❑ Temperature and Pressure Relief Valve properly installed and
discharge line run to open drain.
❑ Discharge line protected from freezing.
D. Wiring
❑ Power supply voltage agrees with water heater rating plate.
❑ Branch circuit wire and fusing or circuit breaker of proper size.
❑ Electrical connections tight and unit properly grounded.
The presence of water in the piping and water heater does not provide sufficient
conduction for a ground. Non-metallic piping, dielectric unions, flexible connectors
etc. can cause the water heater to be electrically isolated.
The branch circuit wiring should include either:
A. Metallic conduit or metallic sheathed cable approved for use as a
grounding conductor and installed with fittings approved for the pur-
pose.
B. Non-metallic sheathed cable or metallic conduit or metallic sheathed
cable not approved for use as a ground conductor shall include a
separate conductor for grounding. It should be attached to the ground
terminals of the water heater and the electrical distribution box. (Refer
to Fig. 3)
The manufacturer’s warranty does not cover any damage or defect caused by
installation, attachment or use of any type of energy saving or other unapproved
devices (other than those authorized by the manufacturer) into, onto or in con-
junction with the water heater. The use of unauthorized energy saving devices
may shorten the life of the water heater and may endanger life and property. The
manufacturer disclaims any responsibility for such loss or injury resulting from
the use of such unauthorized devices.
If local codes require external application of insulation blanket kits the
manufacturer’s instructions included with the kit must be carefully fol-
lowed.
Application of any external insulation to this water heater will require careful
attention to the following:
• Do Not cover the temperature and pressure relief valve.
• Do Not cover jacket access panel to thermostat and heating
element.
• Do Not cover electrical junction box of water heater.
• Do Not cover operating or warning labels attached to the water
heater nor attempt to relocate them on exterior of insulation blan-
ket.
