Boiler Cupboard

I was advised by a Corgi upon seeing my new 'boiler' cupboard that there should be some vents - safety regs in case of boiler overheating. May apply to you.

There is an vent on the wall (which will be inside the cupboard) to the outside of the house.

============== Whatever you build you'll need a low level vent to complement the vent in the wall.

I think this is a situation where a simple MDF or chipboard structure is perfectly acceptable. Make sure that you allow sufficient room inside your cupboard to permit servicing.

Having seen the picture You will definately need a lot of ventilation to outside air.

You will need vents at high and low level. They will have to have a minimum free open area of 5cm^2 per kW of boiler input. However this boiler is an open flue type and will need another 5cm^2 / kW for the combustion air.

That boiler might be around 20kW but it could well be more.

Also I expect that you will need a mimimum 75mm clearance all around to any combustible materials (e.g. wood, ply, wall paper, mdf?)

If this were a modern room sealed boiler you would likely need no vents or such large clearances

wall. Are the requirements you give additional to this?

Yes the cupboard vents are at high and low level whilst the combustion air supply doubles the low level vent.

So at least 10cm^2 /Kw at low level and at least 5cm^2/kW at high level. and 75mm clearance unless the instructions say otherwise.
