| Imported post First off Drifty! If it isn't already, it's "very" soon to be a legal requirement that all new fitted boilers "must" be of the condensing variety.
The horizontal flue length varies from boiler to boiler. That's a manufacturers thing! I'll check the positioning thing, but I suspect that will be a manufacturers thing as they not only need to comply with BS, they also need access to it for repairs/servicing/etc. I'll dig the stuff out tonight and check for you though!
