IMPORTANT WARNING! There is water contained in the coils of your water heater
at all times. If your water heater is exposed to freezing temperatures, the water in
the coils could freeze, causing a break in the heat exchanger of the unit, or the
supply and return lines. This kind of damage will result in water running freely into
the space where the water heater is located, with can cause flooding. If your water
heater is installed in a geographic location that sees very low sustained
temperatures, you MUST install a backflow preventer on your heater's vent pipe.
This will ensure that cold air cannot fall down into the water heater and cause
freezing damage. DO NOT install this water heater where it may be subjected to a
freeze. If your water heater is in an area where freezing is a possibility, you must
turn off the water to the heater and drain it of any water by using the valve stem at
the bottom of the unit and disconnecting the warm water line. Leave the valve stem
and the warm water line disconnected until you intend to use the water heater.
