To Drain The Water Heater Storage Tank
1.
Turn “OFF” the electrical supply to the water heater.
2. Turn “OFF” the gas supply at the Main Gas shut-off
Valve.
3. Open a hot water faucet and let the hot water run until
it is cool (This may take 10 minutes or longer).
Warning:
Be sure the water runs cool before draining the
tank to reduce the risk of scalding.
4. Connect a garden hose to the drain valve and place
the other end of the hose in an adequate drain . Note
that sediment in the bottom of the tank may clog the
valve and prevent it from draining. If you can’t get the
tank to drain, contact a qualified person.
5. CLOSE the cold-water inlet valve to the water heater.
6. Open the drain valve on the water heater.
7.
If not already done, open a hot water faucet to help
the water in the tank drain faster.
8. If a large amount of sediment was present when
the tank was drained, follow instructions in the
“To Flush The Water Heater Storage Tank” section.
9. Close the water heater drain valve when all water in
the storage tank has drained and remove the hose.
10. Follow instructions in the “Filling The Water Heater”
section.
11. Follow the lighting instructions on the label or see
“Lighting Instructions” to restart the water heater.
Note:
If the water heater is going to remain shut down and
empty for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
To Flush The Water Heater Storage Tank
Follow Step 1 through Step 7 in the
“To Drain The Water Heater Storage Tank” section.
1. Flush the tank by opening the cold water supply valve
and letting the water run until no more sediment drains
from the tank.
2. Close the water heater drain valve when flushing is
completed and remove the drain hose.
3. Ensure the heater is full of water.
4. Follow instructions in the “Filling The Water Heater”
section.
5. Follow the lighting instructions on the label or see
“Lighting Instructions” to restart the water heater.
Caution:
Do not turn on power to the water heater unless
the tank is full. Open a hot-water faucet and allow the
water to run until the air is purged and the water flows
uninterrupted from the faucet.
Important:
When operating a cold tank, condensation can
occur and drip on the burner. This should not be confused
with a tank leak.
