Hi I want to box in a boiler and put a cupboard door on the front its a combi does it need a vent on the cupboard ?
If so can the vent be on the inside or outside wall and how close can the vent be on the outside wall to the flue the flue comes up about 300mm then out the wall on an elbow
cupboard will be 350mm deep x 1.4m high x 500 wide
