DRAINING THE APPLIANCE

Essential recommendations for safety

•   Before draining the DHW tank, drain the primary circuit or bring its pressure to 0 bar.

•   Water flowing out of the drain valve may be extremely hot and could cause severe scalding. Keep people 

away from the hot water discharge.

Set-up conditions

• 

Water heater switched off using the ON/OFF mas-

ter switch

• 

External power supply isolated

• 

Gas supply closed

Primary circuit draining procedure 

1.  Make sure the isolating valve (

1

) is closed.

2.  Connect the drain valve (

2

) to the sewer with a 

hose.

3.  Open the drain valve (

2

) to empty the primary cir-

cuit of the water heater.

4.  Close the drain valve (

2

) once the primary circuit of 

the water heater is empty.

DRAINING THE BOILER

Essential instructions for safety

•   Before draining the DHW tank, drain the heating (primary) circuit or bring its pressure to 0 bar.

•   Water flowing out of the drain valve may be extremely hot and could cause severe scalding. Keep 

people away from the hot water discharge.

Set-up conditions

•  Boiler switched off  using the ON/OFF master 

switch

•  External power supply isolated

•  Fuel/gas supply closed

Heating circuit draining procedure 

1.  Close the isolating valves (

1

).

2.  Connect the drain valve (

2

) to the sewer with a hose.

3.  Open the drain valve (

2

) to empty the heating circuit 

of the boiler.

4.  Close the drain valve (

2

)  once the heating circuit of 

the boiler is empty.

DHW circuit draining procedure

Before draining the DHW tank, make sure 

that the heating (primary) circuit pressure is 

null.

1.  Open fully a draw-off tap (

3

) for about 60 minutes 

to make sure that the DHW tank has cooled down.

2.  Close the isolating valves (

1

).

3.  Connect the drain valve (

2

) to the sewer with a 

hose.

4.  Open the drain valve (

2

) and drain the DHW tank 

water to the sewer.

5.  Open the draw-off tap (

3

) to accelerate the 

draining process. If it is located lower than the 

tank connection, open a draw-off tap located 

higher in the system.

6.  Close the drain valve (

2

) and the draw-off tap (

3

once the DHW tank of the boiler is empty.
