    Hi, I've just fitted a new fire door closer, the instructions weren't clear.
    It's very heavy to open
    Can anyone see any obvious errors please ?
    Also what affect does the bar length adjustment have ?
    Thanks Screenshot_20210313-002203_Photos.jpg

    Normally these come with a template that you stick to the door and use.

    Did this unit not come with this? I am surprised the included instructions were not clear.

    Is it one of these units ?

    Once it's in position properly you can adjust the latch and speed.

    Did you adjust the 'latch' and 'closing speed'?

    Thanks, on my instructions it said to tension it, but in the video they dont do that so I think that's the problem

    One arm should be at 90 degrees to frame when installed, looks like you have adjusted return too short.

    The arm which comes off the closer body is the one which should be at 90° to the face of the door. Closer does look a bit near to the edge of the door to my eye, but maybe not. What weight/composition is the door, please?

    I'm not sure of composition of door, but as it's a fire door its heavy.
    Do you mean it looks a bit close to the hinge side ?
    Thanks

    The closer should also be matched to the door weight.

    Yes. But as already stated, the closer power must match the door weight. Does it?

    I've had another look at it, if I move it closer to the frame should that reduce the leverage it has on the door ?

    one the plans there are 2 different positions to have the closer from the hinge, one is 120 degree installation , which is nearee the hinge, and one is 180 degree.

    I've fitted it around 1cm past where it should be for 180 degree, which I guess is giving it too much leverage ?

    Have you adjusted the closing and latching speeds correctly?

    I am now left trying to figure out what you actually mean by it is "very heavy" to open. The thing is that for a fire door closer to work properly it is required to exert a closing pressure of at least 25kgf to meet the regs, unless it is for use in a school environment (I.e where there are many small children) or on a disabled access door where the regs are different

    Thanks, I'm comparing it to the other door I have with a closer fitted.
    Obviously i have no way of measuring the force, just the feeling that its heavier, going to speak to the manufacturer today
    Thanks for your help
