Draining the Water Heater (cont.)
Preferred Drain Method
Isolator valve kits may be purchased from the
manufacturer, distributor, or place of purchase� The kits
include two full port isolation valves to be used in the
inlet and outlet water lines� It is highly recommended
to install isolator valve kits because these kits provide
a means for full diagnostic testing and ease of system
flushing�
Freeze Protection
!
WARNING:
Failure to drain the water heater can cause serious
personal injury from scalding and/or product
damage.
Whenever the water heater may be exposed to freezing
conditions, make sure to completely drain the water from
the unit� See page 20�
Freezing conditions come from the ventilation system
on direct-vent models and from exposure to cold air on
outdoor models�
All of these water heaters are equipped with a freeze
protection electric heater� This heater prevents freezing
inside the water heater down to an ambient temperature
of approximately -30°F (-34°C)� These temperatures are
all based on temperatures without wind�
The heater only protects the internal components of the
water heater�
NOTICE:
Unplugging or disconnecting the power supply to
the water heater will also disconnect the power to
the heater.
External piping and valves require additional freeze
protection� One method is to wrap insulation around the
piping and valves�
Another method is to turn on a hot water faucet and leave
a small amount of water running at a faucet� This will
protect the water heater, piping, and valves from freezing�
Running Water Freeze Protection
Turn off the water heater by pressing the POWER ON/OFF
button on the control panel�
Close the gas shut-off valve(s)�
Open a hot water faucet slightly until the water stream is
approximately 1/8 in� (0�3 cm)� Be sure to check the flow
periodically�
