    Morning all,

    I’m on a new build site and the sparks has installed a extractor fan outlet within 3m of my S&V termination( i Came through a gable end first with NO opening into the fabric of the building within my 3m .. windows or vents) My 110mm termination is to vent a branch that has 6 bosses feeding 2 bathrooms, it comes from beneath the floorboarding and up through the airing cupboard, rises slightly along the attic trusses and through the external gable end wall.
    The boss of the sparks company has said, he’s allowed to terminate the extractor fan vents near my termination, as it’s not a window.

    Has things changed? Is he correct

    Part H states 3mtrs from Openings into Buildings;
    So is an extract vent, probably with flaps and or back draft protection an opening Into?

    1.23 Branch ventilating pipes which run direct to outside air should finish at least 900mm above any opening into the building nearer than 3m (see Diagram 6 and paragraph 1.31).

    Thanks, I wasn’t going crazy then. There’s no flaps on their external vent covers neither

    If I show him that, he’ll probably say that it’s not an intake but an outlet.

    Damn, why can’t the regs be more clear

    Sorry to be a pedant, but he is correct.
    The only people who can settle the dispute are BC - but believe me they won't go anywhere near it :mad:
    Ask him to buy you a beer to not argue the toss ;):cool:

    I’m not bothered, because i brought it to the attention of the customer and he’s not bothered. He says that if BC pull it, he’ll just put an elbow on and send it up past the tiles on the table end.

    Just annoys me that other trades don’t know building regs. Another class one I get from sparks when it comes to drilling through joists is .. ‘ doesn’t matter, they’re only cables’

    Where I spend hours on a new build measuring distances across the span to correctly drill holes

    The answer is that you got there first! Na na nana na! You dont have to quote regs! You literaly won the (installation) race! The spark has come in second!

    For a bit of balance (as I’m a spark) ..

    I was on a big extension recently and the GSR took huge notches out of the tops of all the first floor joists to run pipes .. his view was that the building regs were only guides, not rules.

    Most of the regs we are following are poorly written, liberally interpreted and as for other trades regs .. who cares?

    I try and keep in touch, and reading this forum does help me . but few others do.

    Part F is a good read .

    And BCOs tend to make up their own rules too
