I am about to have a new combi fitted.
Current flue is 20cm above ground level as it emerges from the property.
Regulations specify this must be 30cm now but we have no height internally to raise the flue at all and the flue cannot be turned outside (as it is an internal flue only).
So, we either have to box the flue in outside and raise it (so it is not technially "outside) or I can have the ground below the flue lowered (as it has been excavated anyway for some drain changes. We can infill the hole but leave a trough around the flue exit point so that it is 30cm above the lower ground level.
Do you think this is an acceptable solution?
Thanks,
Charles.
