During Installation of this water heater…
Hot and Cold Pipe Insulation Installation
Insulation Blankets
Insulation blankets, available to the general
public for external use on gas water heaters,
are not necessary. The purpose of an
insulation blanket is to reduce the standby
heat loss encountered with storage tank
heaters. This water heater does not store water
making an insulation blanket unnecessary.
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.
CAUTION: If local codes require the
application of an external insulation
blanket to this water heater, pay careful
attention to the following so as not to
restrict the proper function and operation
of the water heater:
Do not cover the air inlet, flue outlet or
operating and warning labels attached to
the water heater or attempt to relocate them
on the exterior of insulation blanket.
WARNING: If local
codes require external
application of
insulation blanket kits
the manufacturer’s
instructions included
with the kit must be
carefully followed.
NOTICE: The hot
and cold pipes should
be insulated as shown
to provide additional
freeze protection.
WARNING: In case
the pipe insulation is
not rated for the
appropriate weather
conditions install
electric heat tracing or
equivalent to prevent
freezing of the pipes.
Do not insulate or
block drain valve on
the hot outlet fitting. If
the pipes are allowed
to freeze, the water
heater and the pipes
may malfunction or
leak due to freezing
water.
