My installation has been classed as Dangerous 'Do not use' by my boiler manufacturer. I have an Ideal Logic 30kw Combi boiler mounted as high as can be on the kitchen wall. Flue exits out through the wall via an elbow but emerges above a flat roof. Unfortunately it's somewhat less than the regulation 300mm above.
I had suggested just fitting a couple of concentric elbows with a vertical concentruc length outside the wall to raise the horizontal terminal higher than the 300mm requirement. However, I'm told by my installer that Ideal says it can't be done on a fan room sealed flue!?
Ideal have told my installer the only option is to extend the flue vertically from the boiler up through the ceiling and into our bathroom then elbow out through the wall under the sink.
This would obviously be a big upheaval for us and would need a second hole knocking through the wall and I would have to box it in finally.
Does anyone have any experience of mixing horizontal and vertical concentric flues like I suggested outside of a building? Why can't it be done?
