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
