DRAINING THE WATER HEATER
To drain the water heater:
• Turn off the water heater (refer to “To Turn Off The Water Heater” on
page 23).
• 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.
• Undo the union at the cold water inlet to the water heater and attach a hose
to the water heater side of the union.
Let the other end of the hose go to a drain.
• Operate the relief valve again.
This will let air into the water heater and allow the water to drain through the
hose.
