Draining the Water Heater
Freeze Protection
Where the water heater may be exposed to
freezing conditions, even for a short
period of time, be sure to drain all water
from the unit as instructed above.
Exposure to freezing conditions can occur
from down draft of venting system or
from installation in areas exposed to cold
air.
The water heater is equipped with a Freeze
Protection Electric Heater. As long as the
electricity is supplied to the water heater, it
prevents freezing inside the water heater up
to an ambient temperature of approximately
minus 30°F (without wind-chill factor)
This device only protects the internal
components of the water heater. It does
NOT protect piping and valves. Therefore,
piping and valves should be wrapped with
insulation material as instructed on page 21.
Another method of freeze prevention is by
running a small volume of water. Running
water will protect the water heater, piping
and valves.
Follow the steps below to ensure proper
water flow through the water heater and
piping:
Turn off the switch on the remote
control.
Close the gas shut-off valve.
Open the hot water faucet slightly until
a stream of approximately 1/8” is
flowing. Be sure to check the flow
periodically.
WARNING: Failure
to drain the water
heater can cause serious
damage to the water
heater as well as
personal injury.
!
Below are instructions for draining water
out of the water heater.
Turn off the switch on the remote
control.
Close the gas shut-off valve(s).
Unplug the power supply cord (or
disconnect breaker) at least 10 seconds
after step #1.
Open all hot water faucets. Before
proceeding to the next step, make sure
that COLD water is coming out of all
hot water faucets.
Close the water shut-off valve.
Using a suitable container to catch
water, remove the water filter from
heater. Attach a garden hose to the
drain valve installed in the hot water
outlet line and direct the stream of
water to a suitable drain where it will
cause no damage. Approximately 21oz
of water will be drained. Leave water
heater as is until next use.
To put the water heater back into
operation after draining, follow the steps
below.
Reinstall the drain plug and water filter.
Close the hot water outlet drain valve.
Open the water shut-off valve and close
again after making sure that water
comes out from hot water faucets.
(This step is to remove air from the
water lines.)
Plug into an electrical outlet, fully open
the gas shut-off valve and the water
shut-off valve.
NOTICE:
The water heater may not
operate unless the above procedure is
followed correctly.
