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.
