Today's building codes state spaces using furnaces will need to have means for getting together again combustion air as it used. Newer homes have ducting installed, during construction, thats liable to bring oxygen on the surface to a area close to the furnace. This ducting, usually called constitute air duct, or combustion make-up air, is sized according to the capacity in the furnace. We’ve been determined to create a more productive conversation and shared vision for improving competitiveness through decarbonisation and energy efficiency – and to get people on all sides to understand one another and be ready to play their part. I want to express my thanks to the British Glass staff who have made this happen.”
