A question for the Gas Safe guys

Yolina

I have a circa 24 years old Potterton Profile 60E (fanned balanced flue) which is working absolutely flawlessly and that I have therefore no intention of changing for the time being. It is located in a fairly large cupboard with a number of vents (2 to another room and 2 to outside).

Now, the outside vents have been causing me some trouble when I get the boiler serviced because their distance from the flue isn't current regs...
I pulled out the install sheet from the web and according to that, because the vents are positioned diagonally from the flue, it looks like the minimum distance then was 15cm. So as far as I am concerned, it was done correctly at the time of install, which was when the place was built.

The install sheet mentions that if fitted in a cupboard, there should be air vents top and bottom with each having a free area of 206cm2 and that if the openings draw air from outside the building, the free areas may be halved.

The vents between the cupboard and the room are 25cm x 30cm at the top and 20cm x 15cm at the bottom.
The vents to the outside are 20cm x 20cm each

So does that mean that it would actually be fine to block off the vents to the outside (as was strongly advised to me at the last service) without causing the boiler to overheat? Would certainly make life easier for me if were indeed safe to do so.

Thank you

AFAIK, the boiler is room-sealed; the place had DG from the time it was built too.

Basically for years I had a RGI who said to leave it alone and to just get it all done when I eventually change the boiler (fine by me). However that guy has now moved away and so doesn't cover my area anymore. Been trying different people over the last few years and been getting different reactions and suggestions every time :rotfl:(and collecting "at risk" paperwork...)

Just block off the vents that go to outside. For compartmental ventilation of a roomsealed appliance you need a top and bottom vent which both communicate with the same exterior and interior space and they need to be of a cross sectional area as defined in manufs instructions. You do not need outside AND inside vents

the boiler only req the vents in the cupboard to prevent over heating, as long as you have 206cm2 at the top & the bottom of the cupboard this is fine, you don't need the external vents to outside, however with this boiler make sure your RGI checks the case seal as it's a positive pressure boiler

Thanks. So it looks like the last guy I had in to do a service will get my repeat custom then as he's the only one so far who suggested a quick, simple (and cheap) solution.

Now any suggestions as to the best way of blocking off those vents?

The profile is a very good boiler and you shouldnt consider binning it unless it falls off the wall and is totally finished.

I know and that is exactly my plan.
