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 48).
•
Close all hot water taps.
•
Operate the relief valve lever - do not let the lever snap back or you will damage the valve seat.
It is very
important the lever is raised and lowered gently
.
Operating the lever will release the pressure in the water heater.
•
Undo the union at the cold water inlet and attach a hose.
Let the other end of the hose go to a drain.
•
Open the relief valve by holding the lever in the raised position.
This will let air into the water heater and allow the water to drain through the hose.
