Freeze Protection
Make sure that in case of freezing weather that the
water heater and its water lines are protected to
prevent freezing. Damage due to freezing is not
covered by the warranty.
Loss of freeze protection may result in water damage
from a burst heat exchanger or water lines.
With electrical power supplied, the water heater will
not freeze when the outside air temperature is as cold
as –22°F (-30°C) for indoor models, when protected
from direct wind exposure. Because of the “wind-
chill” effect, any wind or circulation of the air on the
unit will reduce its ability to freeze protect.
The unit may be drained manually. However, it is
highly recommended that drain down solenoid valves
are installed that will automatically drain the unit if
power is lost. These are available in a kit, P/N
15000029-A. (The condensate trap drain plug and
water drain plug are not affected by the auto drain
down solenoid valves and will have to be manually
opened.)
In addition, the solenoid valves should be connected
electrically to a surge protector with terminals. This
allows the solenoid valves to operate if the water
heater is disabled due to a diagnostic code.
The freeze protection features will not prevent the
external piping from freezing. It is recommended that
hot and cold water pipes are insulated. Pipe cover
enclosures may be packed with insulation for added
freeze protection.
It is recommended that the condensate trap drain line
be insulated. A frozen condensate trap drain line
results in diagnostic code 25.
In the event of a power failure at temperatures below
freezing the water heater should be drained of all
water to prevent freezing damage. In addition, drain
the condensate trap and drain line.
