Hi
Previous Landlord's Gas Safety Certificates over the last 7 years on a flat I let out have passed fine, but latest one failed due to the boiler flue termination being too near the openable kitchen window (about 270mm when regs. state it should be >300mm).
Flat is ex-council on 3rd floor in a block built in 1977 - I bought it in 2007 - Googling seems to suggest that the 300mm rule was introduced in 2008(- true?) - strange that previous checks have passed A-OK - just the luck of the draw, or have things tightened up recently?
Anyway, currently the flue takes a 90 degree turn out of the (Vaillant Turbomax), trough the brickwork wall, then terminates.
What I'm thinking is to put another 90 deg. elbow on the outside & then a short vertical extension to get it up & out of the way.
(as the flat is on 3rd floor it would be a real pain to have any work that couldn't just be done from leaning out of the kitchen window).
Is this a reasonable plan? Any possible pitfalls?
( - Photoshop of what I have in mind):
