I have a brochure for a combi boiler. There is a note which states: The distance from a fanned draught appliance terminal installed parallel to a boundary may not be less than 300mm. Is this to prevent problems should an extension be built in the future. In a situation where there is no possibility of an extension being built could this regulation be waived. I only ask cos if this reg must be strictly adhered to it is going to have a bit of an impact on our kitchen design.

Out the back wall is correct but would ideally like boiler installed on party wall. Property is terraced. No chance of any extension being built as there is a road outside the back door. Haven't done any proper measuring yet. I suppose I could visit manufacturers website and try to get the dimensions I need. It just looks as though it will be tight if the brochure is anything to go by. Kitchen planner is coming Tuesday so i need to have it ironed out by then.

[quote author=billythekid  link=1125785085/0#3 date=1125788359]ok stop me if i'm getting this all messed up in my(whiskey soaked) brain, but how can you flue a boiler on a party wall? I think you mean right up against your party wall with the flue thru the back wall right? or even side exiting flue with boiler mounteed on party wall.  if thats the case you might well be cutting it close.  there are other regs too which might com into effect, proximity to openable windows etc.

The answer I suppose is that you definately need to take notice of this reg, its concerning products of combustion i.e carbon monoxide in a worst case scenario.  If your neighbour puts up a conservatory you wouldnt want to be the one responsible for their deaths just because it fitted your kitchen layout better would you. I'd ask your neighbour if they are ever going to build onto their property, or even if they would be allowed to, depending on your area they might not be able to get the planning permission to extend. If the boiler definately HAS to go there then this is your only option.

Would it be possible to put it up the loft or somewhere else in the house? [/quote]

Spongebob.....have you also considered Quote:
? You need to check all these aswell. Usual all these dimensions are given in the manufacturers insatllation manual, if not they are freely available at the odpm website under part J. Or try here Flue position

Assuming it's a public footpath then I think,  and my  collegues will confirm you are not allowed to discharge the flue over a public area.

Sorry I can't give you a better answer but I don't do domestic.

Flippity flip scruff!!!! There's a bombshell. I hadn't come across that in my research and it wasn't mentioned to us by the guy who we originally approached to do the installation. Is it just the new condensing boiler flues that this applies to or is it all combis. If it's all combi's there are a few illegal installations around here. We currently have a back boiler and were looking to change to reclaim space in the loft for a conversion. I cant think of another suitable place to put it. This is a BUMMER!

In the loft with a vertical flue kit might be a location ?

spongebob, did your read and digest my previous post? There is a ray of hope...

Me again. chrishutt, 2metres is easily achievable but I ain't come across Keston boilers in my trawl for brochures. will look them up.
Had a word with a plumber today who was working in the street. He wasn't aware of this reg and he dug out his little corgi manual and was unable to find any specific reference. I'm further confused by the fact that there is at least one condensing boiler installation nearby that was carried out by a long established local company. oh for the day when gas runs out and we all go back to coal fires.

I've read Approved Doc J. I've read the condensing boiler assessment procedure. Due to the type of property I have I think I'll be struggling to install a condenser. However I feel that the info I have gleaned will help me weed out the good from the bad when it comes to getting quotes. I'm going to bed now. I have a headache from all those regs. Don't know how you guys manage on a daily basis!

scruff. I've read all that. I could get the height no problem. The issue now is the boundary matter and I'll have to make enquiries to clear that up. At the rear of the property the set up is as follows, back door, footpath, access road, communal lawned area. Although the local council do the grass cutting I'm almost certain that my boundary extends into it . It's all a bit of a pain really. One additional note. I e-mailed this info to a mate. He paid last year to have his conventional boiler moved from a bedroom into a out house. Now if he changes to a condenser he won't be able to use his drive without considerable flue extension. I've still got the head ache by the way.

Just curious... why is it harder to install a condensing boiler than a non-condensing boiler? The condensing gas boiler we have is quite small and there are no extra pipes or anything so I'm slightly confused as to why you think they are harder to fit in?

Perhaps I've missed something - I'm no expert!

Well now you've got me thinking. We don't have a pipe for the condensate. Humm I'm beginning to wonder if our boiler really is a condensing boiler!

It's a Bosch/Junkers Cerastar but I've only found limited  data for the model we have on the web...

In dutch it says...

In sommige ruimtes is het (bijna) onmogelijk om een luchttoevoerbuis te installeren. Een open toestel biedt dan uitkomst, mits er voldoende ventilatie is. Als u kiest voor de Bosch Junkers Cerastar hoeft u geen concessies te doen aan uw comfort. (verbeterd rendement uitvoering)

Which  I think says...

In some spaces it is (almost) impossible install a ventilation pipe (condensate pipe?). An open appliance brings then help, provided that there is sufficient ventilation. If you choose you no do concessions to your comfort for the bosch Junkers Cerastar must. (improved output implementation)
