IM interested in finding out what the regulations are relating to fitting a new flue on an existing condensing combi boiler a heatline viso 24 plus.
My partner recently had a single storey extension built on the back of her house. Since the existing boiler was fitted onto the inside of a previously outside facing wall, the builder re routed the flue to exit through the extension flat roof.
The existing flue simply exited the boiler from the top and then turned 90 degrees horisontal to go through the wall and exhaust outside. After the extension was added, the builder modified the flue by adding a new 90 degree horisontal joint to the old outside wall and a 3m straight section paralell with the old outer wall before adding another 90 degree vertical joint so that the flue exits through the flat roof. The end of the flue is approx 30cm above the flat roof and 30cm from the existing outside wall.
The builder boxed in this flue arrangement to make it tidy.
Recently the boiler broke down and after calling a gas engineer we were told that this was an illegal installation. apparantly having a 90 degree vertical flue extension is against regs as well as having no inspection panel in the boxed in area.
Obviously we are upset as we thought the builder knew what he was doing and believed the council had inspected the works and passed it.
So the question is what to do next? We will go back to the builder and claim compensation for an illegal installation but we would like clarification on what the regulations state for flues. The extension has two velux windows which can be opened and also there is a window above the extension which can be opened. How far must a flue be away from these areas and must it exit from the roof or is a side exit an option?
All info welcome.
