Restarting after Maintenance

Conditions:

Procedure:

1. 

Press the On/Off switch located on the right 

side of the control panel. 

The switch is illuminated when in ON 

position. 

2. 

Select the required heating mode as re-

quired.

3. 

Activate the DHW mode as required.

4. 

Allow the appliance to operate for a few min-

utes, then bleed the air from the system.

Follow-on tasks:

1. 

Check there is no leak in the water and gas 

circuits.

2. 

Check the combustion values according to 

“Combustion and Gas Data” on page 

G-15

.

3. 

Record values in 

“Combustion Parameters 

- Log Sheet” on page I-81

.

4. 

Check the heating circuit pressure (between 

1.5 and 6 bar).
