Oil Rayburn Flue Clearance

Rdwill

Hi

I am in the process of installing my new kitchen, but have come up against a risk / issue that I did not anticipate.

To provide heating, hot water and occasional cooking I have an oil fired Rayburn 480k, it's about 20 years old. 

The clearance that I have between the flue pipe and the cabinets is my concern. At the top I have just over 25mm, but running down the side there is circa 17mm of clearance at the narrowest point.

Part J of the building regs states that I need 25mm from the flue to combustible material.


Is this a risk that I except or do I need to do some re engineering of the cupboards to buy me c8mm to comply with the building regs. I doubt the Building Control Inspector will look at this as the Rayburn is an existing installation. But I don't want to risk burning the house down.

Is there anything else I can do to mitigate the problem, 

Thanks in advance

You will find that the melamine coating on the units will bubble and fall off the underlying chipboard. Flues get really hot, and even 25mm is not enough in my opinion. In addition, you need plenty of clearance where that (silver) plate is bolted on. This is where a brush & rod would be inserted to clean the flue out.

I would suggest removing the right hand wall unit and the bridging unit over the top.

I think I'm going to turn the right hand wall unit into a 500mm unit the same as over the Rayburn and put some of that reflective panel that goes behind radiators under the unit.
