Vent Pipe Blanked Off

[carl233]

Would appreciate some advice I have a Potterton Suprima 60 Boiler system and a plumber doing a routine inspection of the system has stated in their opinion the system is not safe. This they have raised is due to no vent pipe being fitted to the F&E tank. Is anyone able to say if this information is correct, I should say the system has been working fine for well more than a decade without such a vent pipe. Any information and help is most welcome.

Assuming what the OP has is what is shown in figure 3 on page 10 :

Plumbase Manuals

then I fail to see the problem - it meets the boiler manufacturer's installation requirements and the boiler is designed to be installed this way. The OP's plumber may be used to older boilers that did not have the failsafe devices that allowed this kind of installation?

EDIT - just noticed the lack of vent on the cylinder, however. Is that supposed to be a vented or unvented cylinder - can others please comment?
