DRAINING THE WATER HEATER
To drain the water heater:
Gas Booster Water Heater
•
Turn off the water heater (refer to
“To Turn Off The Water Heater”
on page 50).
•
Open a hot tap (preferably the shower outlet).
•
Unscrew the two drain plugs, one each at the cold water inlet and hot water outlet, on the
underside of the gas booster.
Water will drain from the gas booster.
•
When water stops flowing from the gas booster, close the hot tap.
Note:
It is recommended not to screw the drain plugs back in, until the water heater is to be turned on
again.
Solar Storage Tank
•
Turn off the water heater (refer to
“To Turn Off The Water Heater”
on page 50).
•
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 solar storage tank 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.
