How to clean Venturi?

on this make off boiler the venturi are a big problem and would require a new one as if you remove the fan to inspect the venturi, u will notice it will have become very brittle. and this causes it no to give the aps a correct volume of air pressure to activate the switch. but this work should carried out by a proffesional boiler engineer as you will be breaking into the combustion chamber and breaking the flue system also.

I'm afraid that you would be breaking the law to undertake this work yourself, as the Venturi is part of the flue system, you need to contact a RGI to do this for you
