DRAINING THE WATER HEATER
Warning: Exercise care, as water discharged from the water heater may be of a very high temperature.
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.
