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 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 elec-
trically 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 purpose.
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 dis-
tribution 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 sav-
ing or other unapproved devices (other than those authorized by the
manufacturer) into, onto or in conjunction 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 care-
fully followed.
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
blanket.
