To drain the water heater: 
 
Gas Booster Water Heater 

•  Turn off the water heater (refer to 

 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 

 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.
