Abstract

The cowl is mounted on a concrete base which is in the form of a ring and is located at the top of the chimney. The cowl itself is bolted onto the base. It has a number of curved vertical baffles arranged in three concentric rings. The object of the baffles is to divert any cross wind round the outside of the flue. The cross winds are normally responsible for preventing the hot flue gases from escaping. The rings may be circular of the baffles may be arranged in concentric squares with rounded corners. RAin cannot enter a chimney fitted with this cowl.
