Need An Air Intake Solution For Your 90+ Appliance Masonry Chimney Reline?

Some appliances require combustion air to come from the same pressure zone. This system creates the balance needed when using a masonry or sheet rock chimney to exhaust your high efficiency appliance’s flue gases. Certain codes and regulations may also prohibit you from drawing combustion air from the enclosure itself so you need an additional flex to supply combustion air. The use of aluminum flex is helpful given its low cost, light weight and is readily available.
