went to this boiler today it has a kitchen cupboard around it but has more than the req clearances 105mm at sides 600mm from top to ceiling 600mm from bottom of boiler to worktop .100mm from front to door . cupboard vented 200cm2 at top and 600cm2 at bottom. room vent 100cm2 .the issue I have is the flue does not rise 600mm to first bend - has twist joint ontop of boiler giving a small offset and an angle of not quite 45 so flue is NTCS.manual states compartment must be of 1/2hr fire rating but this one has more than the min clearances so would that still count . 2 NTCS on flue or ventilation make AR but compartment material would not count as a second NTCS on flue or vent would it.otherwise flue pulling good and no spillage.
