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. Leave water heater
as is until next use.
T
o 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

Draining the water heater
WARNING: Failure
to follow these
instructions while
draining the water
heater can cause serious
damage to the water
heater as well as
personal injury,
including scalding.
NOTICE: DO NOT
unplug the electric
power supply cord for
freeze protection.
Care and cleaning of 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
electricity is supplied to the water heater, it
prevents freezing inside the water heater down
to an ambient temperature of approximately
minus 20°F (-28°C) (without wind conditions).
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 24.
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” (.32 cm) is
flowing. Be sure to check the flow
periodically.

Optional Maintenance Method
Isolator valve kits may be purchased as optional
items from manufacturer, distributor or place
of purchase. They allow for one person full
diagnostic testing and ease of flushing the
system.
The kit includes two full port isolation valves,
one for the cold side and one for the hot side.
CAUTION:
Even when drained
properly, a small amount
of water will remain in
the water heater. In cold
weather, conditions this
water can freeze. If this
happens allow the defrost
protection on the heater
at least 30 minutes to melt
the frozen water or the
water heater may not
work properly.
