ferroli flue leaking

[plumber0808]

is it possible to get new flue seals for a ferroli optimax 25 ov.

its leaking into the air intake on the fittings and making its way back to the boiler running down and corroding it.
the flue is plastic. i want to take it apart re- seal it and put it back together, but cant find any part numbers for the seals. i am going to phone ferroli tomorrow.

ferrolis are bad boilers, the local merchant tried pushing these my way '5 year guarantee' ..... no thanks
