Can 87-degree bends be used on vertical flue systems?

October 24th 2023

Yes, on our condensing boilers, you can fit 90-degree bends onto a vertical flue system. Note: An 87° bend is equivalent to 1.3m length of flue. If it is necessary to use an 87° bend in the vertical flue, ensure any horizontal flue lengths are sloped towards the boiler to ensure that all condensate is allowed to drain from the flue. The slope must be a minimum of 25 – 30mm per meter.
