Draft is the force created by a difference in pressure, which moves air from the appliance up through the chimney. It is important to operate the Astra 38 with proper draft to ensure optimal performance of the unit. Draft is depended on the length of the chimney, local geography, nearby obstructions and other factors. Proper draft results in an upwards flow through chimney, which prevents smoke infiltrating into the house during operation of the unit.
