22. ADJUSTMENT AND SAFETY DEVICES

The boiler has been designed in full compliance with European reference standards and in particular is fitted with the

following:

• Air pressure switch (model 24 MI FF - 24 FF)

This device only allows the burner to ignite if the exhaust flue duct is in perfect working order.

In the event of one or more of the following faults:

• flue terminal obstructed

• venturi tubes obstructed

• fan blocked

• venturi tube connection - pressure switch tripped

the boiler remains on standby and error code E03 is displayed (see table in section 10).

• Fumes thermostat (model 24 MI - 24)

This device has a sensor positioned on the left section of the fumes hood and shuts off the gas flow to the main burner

if the flue is obstructed and/or if there is no draught.

In these conditions the boiler shuts down and displays error code E03 (section 10).

After eliminating the problem, press button ( ), for at least 2 seconds to re-ignite immediately.

It is forbidden to disable this safety device
