Abstract
The heater has a finned tube heat exchanger (3) above a gas burner (11). The flue gases pass over the heat exchanger and are evacuated through a flue (6) by a constant speed fan (4). Combustion air enters through an annular duct (5) surrounding the flue, and flows round the outside of the heat exchanger assembly to reach the burner and combustion space. A damper (1) admits a portion of the fresh air drawn directly into the flue passage (6), thus reducing the amount of air reaching the burner for combustion. This damper is operated through a lever (17) by a thermostat (6) in the flue gas immediately above the heat exchanger. The volume of combustion air is thus regulated by the temperature of the heat exchanger.
