    The engineer was happy with the pump pressure.

    If the engineer can’t get the air down enough seems it’s always been high on air it may be an idea to fit an air disc. Bob

    No echo Terry, but I'm of the opinion that if the original points aren't answered, then repeating the suggestion eventually gets to the bottom of the problem.
    We now have a nozzle size which reinforces our several suggestions of over aired start up. We now also know that the boiler has a direct air feed from outside, which I have encountered in the past where you can get a howling gale direct into the fan, (and also mice, ask me how I know) without any 'tempering ' as you get on true balanced flues, and also a draw off the conventional chimney.

    I'm pretty sure the two Heating WorldsI service take an 80o Nozzle.

    I see very few Heating Worlds around here and avoid them if possible.
    There is one I have repaired with an electrically operated flue damper .
    I think that is HW.
