DRAINING THE WATER HEATER
To drain the water heater:
•Turn off the water heater (refer to “To Turn Off The Water Heater” on page 32).
•Close all hot water taps.
•Operate the relief valve release lever - do not let the lever snap back or you will damage the valve seat.
Operating the lever will release the pressure in the water heater.
•Attach a hose to the water heater drain cock. Let the other end of the hose go to a drain.
•Open the drain cock.
•Operate the relief valve again.
This will let air into the water heater and allow the water to drain through the hose.
