Thanks. Yes good point, in fact I've been trying to get hold of a
manual to check this in parallel with my original post, without
success. I also don't know what the overall room ventilation
requirements are.

Would anybody happen to have a manual, or be able to suggest where I
could get one? I can't even track down the UK distributors at the
moment. (Boiler is a Sime combi, Friendly Format 100E).

Nobody's commented on whether I can locate my boxed-in boiler on the
landing (my preferred location); I've never seen this done before and
wonder whether it's a no-no (eg fire risk?)


I have the manual to hand for the Friendly but alas not the Friendly
Format. However its likely to be equivalent since from memory the casing
construction and insulation is similar. This DOES require compartment
ventilation to BS 5440:2

The landing has no particular problem for the installation of this model as
long as you can meet the maximum flue length required. Varies slightly
dependant on rear, left or right flue entry but about 2.3 metres max
equivalent length
