    Hi Mudguts.
    I presume you have the 6" SS inner flue and the 8" Gal outer?

    The inner SS flue goes upside down to what you think, ie, spigot down (crinkly end down), this is so all the tar and moister from the heater runs back into the heater again otherwise it makes one hell of a mess in your room.

    Apart from that, the installation is pretty much easy, just make sure there are no timbers in the roof that are in the way or too close to the flue.

    Just make sure you use the same flues as the origional, make sure to check for combustable matierial around your flue after install, eg insulation.
    Ozzy is correct about the install method.
    You shouldn't obviously have to cut your roof for a straight swap, but dont leave little tiny bits of metal (swarf)on the roof after, make sure to sweep it down, it can cause rust, If the swarf is sticking to the dek make up a strong mix of dish detergent in a spray bottle and use it to lubricate the swarf( sounds ridiculous but works), dont slip off though.
    I use silicone on the dek tites, they have a heat resistant one for flues hope you know.Fix it from the middle of each edge out to the corners. MAke sure you have a good clean roof to stick to if not clean it before silicone.
    Make sure to finish the flue at the same height as the origional, It does make a difference in the operation, 100 mm probably wont matter but 1m definately will. Whatever you do don't make it shorter .

    Hi Bricks, just noticed that you said to make sure that you finish the flue at the same
    height as the original, that it will make a difference in the operation.

    Can I just ask what happens to the operation if the new flue is installed higher than the original?
    I am just asking because I had a flue replaced last year, and am now having some issues with the operation that have not occured before

    Flues should be a minimum of 600mm above any roof point within a 3 meter radius & some councils are now requesting - 1 meter above any neighbouring structure within 15 meters.

    Most manufacturers have a max & min flue length for particular units but it is hard to fall outside this range causing the flue to not draw properly.
