Air Conditioning onaHe*w Automatic Gas Equipment Company Brushton and Thomas-St., Pittsburgh 21, Pa. Manufacturers of Pittsburgh Gas Unit Heaters and Duct Furnaces Cast Iron Heating Elements Cast iron is considered to be the best material to withstand . the corrosive effects of the products from combustion of gases. For this reason, both the heat exchanger and combustion cham ber in a Pittsburgh Gas Unit Heater are made of cast iron. Furthermore, they are cast in one piece and the ex tended heating surface fins on the heat exchanger are cast integral. Pittsburgh Gas Unit Heaters have been designed to consume exactly the right amount of air to support complete combustion but without permitting an excess of air to lower heating efficiency. This is accomplished by means of a built in draft hood which absorbs all excessive chimney action and thereby conserves heat. The heater does not depend upon forced draft from the fan for either the primary or secondary air supply. For this reason there is no possibility of variation in the air supply to the burners resulting from changes in fan speed or louver adjustment. By the use of adjustable horizontal louvers, warm air can be directed to any desired level. Safety Features A tested and proved safety pilot is used oh these heaters to automatically turn off the gas if the pilot light goes out or if it burns too low to insure posi tive ignition. The draft diverter is absolute protection against any possible down drafts through the chimney. Write for folder containing complete details, including installation measure ments.
