4. Bleed the air from the radiators.

5. Check the pressure gauge reading to verify that there is

suffi cient plant pressure (1-1.5 mbar); if not, the display will

signal the need for re-establishing the pressure.

Re-establish the pressure by opening the water inlet valve

located underneath the boiler.

6. The exhaust duct for combustion products should be suitable

and free from any obstructions;

7. Any necessary ventilation inlets in the room should be open

(type B installation).

8. Check whether the siphon contains water; if not, it must be

refi lled.

N.B.: if the boiler will not be used for long periods, the

siphon should be fi lled before the boiler is started up

again. It is dangerous not to refi ll the siphon as fumes may

be released into the environment.

9. Open the gas valve and check the connection seals, including

the boiler connection seals, making sure that the meter does

not detect any passage of gas. Eliminate any leaks.

10. Start the boiler by selecting the heating or domestic hot water

approximately 7 minutes. When this is complete the menu

screen will be restored. The cycle may either be repeated, if

necessary, or stopped by pressing E
