Air Conditioning Direct-Fired Heaters Arthur A. Olson & Company Broad and Court Streets Canfield, Ohio Manufacturers of Direct Fired Heaters A completely automatic direct-fired unit heater. Olson heaters operate on gas, oil, dual gas-oil or coal. These units may be hung, suspended horizontal, or inverted. All heaters can be adapted to filtering, humidifying and air condition ing. Use of standard accessories and easy access to bearings and other vital parts simplify maintenance. Also process and make-up air applica tions. Engineering Data--Gas, Oil, or Dual Gas-Oil Heaters.

Manufacturers of Pittsburgh Gas Unit Heaters Cast iron is considered to be the best material to withstand the corrosive effects of the prod ucts 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 extended heating surface fins on the heat exchanger are cast integral. Pittsburgh Gas Unit Heaters have been de signed to consume exactly the right amount of air to support complete combustion but without permitting an excess of air to lower heating effi ciency. 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 possi bility of variation in the air supply to the burn ers resulting from changes in fan Bpeed or louver adjustment. By the use of adjustable hori zontal louvers, warm air can be directed to any desired level. Cut-awav view of heater, showing the east won heat exchanger in "place. Safety Features A tested and proved safety pilot is used on these heaters to auto matically 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, ineluding installation measurements.
