XXXXX XXXXX : There is nothing in the instructions about the maximum flue length, but normally it is 3m
XXXXX XXXXX : for every 90 degree bend you install, it takes 1m off the flue length including the one off the top of the boiler
Customer: Counting the elbow on top of the boiler the length is 2.7 m to the external wall do you think this will work ok with this boiler as I don't want to buy an extension pipe if not suitable many thanks Steve
XXXXX XXXXX : This will be too far as after the first bend only leaves 2m, are you able to take it upwards with a vertical flue?
Customer: No , bedroom above ,your first advice told me there no maximum length but in general you said 3 m as a guide line there is no where else for boiler to go can do 2.5 at a push thanks steve
XXXXX XXXXX : Not possible.
XXXXX XXXXX : you say it is too wide for the space next to the window?
Customer: Yes, it would cover half the window with the water tank behind it
XXXXX XXXXX : can you spin it through 90 degrees and mount it on a side wall?
XXXXX XXXXX : if there is not one there can you build one to hang it on, you would om
Customer: no , it's an internal room
XXXXX XXXXX : only lose 4" for the wall?
XXXXX XXXXX : Then hang it sideways?
Customer: Bathroom behind it, and kitchen other side
Customer: Never thought of that , that would actually work ! Thank you for your help , Steve
