Instructions
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 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 carefully followed.
Application of any external insulation, blankets or
water pipe insulation to this water heater will require
careful attention to the following:
• Do not cover the temperature and pressure-relief
valve.
• Do not cover access panels to the heating elements.
• Do not cover the electrical junction box of the
water heater.
• Do not cover the operating or warning labels attached
to the water heater or attempt to relocate them on
the exterior of the insulation blanket.
• Do not block the air inlet/outlets in the top covers or
rear of the unit.
