DRAINING AND FILLING THE WATER HEATER
D raining the Water Heater
The water heater should be drained if being shut down
during freezing temperatures. Also, periodic draining
and cleaning of sediment from the tank may be
necessary.
1. Turn off the gas to the water heater at the manual
gas shut-off valve.
2. Open a nearby hot water faucet until the water is
no longer hot.
3. Close the cold water inlet valve.
4. Connect a hose to the drain valve and terminate
it to an adequate drain or external to the building.
(Make sure all connections are tight and that the
water flow is directed away from people.)
5. Open the water heater drain valve and allow all the
water to drain from the tank. Flush the tank with
water as needed to remove sediment.
6. Close the drain valve, refill the tank, and restart the
heater as directed by the lighting instructions on
the front of the water heater.
If the water heater is going to be shut down for an
extended period, the drain valve should be left open.
IMPORTANT: Condensation may occur when the cold
tank is first heated and should not be confused with a
tank leak.
F illing the Water Heater
Never use this water heater unless it is completely full
of water. To prevent damage, the tank must be
fi lled
with water. Water must fl ow from the hot water faucet
before lighting the water heater. NOTE: The hot water
faucet used should be the one furthest from the water
heater.
To
fi ll the water heater with water:
1. Close the water heater drain valve.
2. Open the cold water supply shut off valve to the
water heater.
3. To ensure complete fi lling of the tank, allow air to
exit by opening the furthest hot water faucet. Allow
water to run until a constant
fl ow is obtained. This
will let air out of the water heater and the piping.
4. Check all new water piping for leaks. Repair as
needed.
