Burners, Oil Williams Oil-O-Matie Heating Corporation Manufacturers of Automatic Oil Burners Bloomington, Illinois _ NEW YORK, N. Y., 420 Lexington Avenue CHICAGO, ILL., 185 N. Michigan Avenue Authorized Dealers and Factory Trained Installation and Service Organization in all Principal Cities of the United States and Canada, also in 75 other large Cities throughout the Civilized World. Williams Oil-O-Matic Heating is 10 Years and 90,000 Installations Beyond Experiment Williams Oil-O-Matic heating for domestic or commercial installations can be safely recommended by heating engineers, con tractors and architects. Today more than 90,000 Williams Oil-O-Matic installations in every state and province, from Alaska to Australia, are automatically and satis factorily maintaining predetermined tem perature in any weather. In many instances Oil-O-Matic fuel costs are no higher than for hard coal-- thousands of enthusiastic owners even claim savings:--and the work of hand firing coal, removing ashes and cleaning dust and smudge is eliminated. Advantages--To burn oil efficiently: (1) Oil must be atomized, not vaporized. (2) Oil must be mixed with, a fixed minimum quantity of air. (3) Oil must burn in suspension. (4) Oil must burn in the presence of a refractory material. Oil-O-Matic operation complies strictly with these well-known natural laws governing the combustion of liquid fuel, as outlined in Dyson's "Naval Engineering," and the reference works of Harding and Willard Kent, and other like authorities. The patented exclusive Oil-O-Matic metering pump permits burning cheap 28 to 30 deg. Baume fuel oil, but will handle equally well, all lighter furnace oils. Change in fuel does not necessitate a change in burner adjustment. Oil-O-Matic method of atomization eliminates all high pressure and needle valve atomization. Oil-O-Matic air control permits use of a low velocity air blast, adjustable over a wide range of service, to meet the require ments of all existing types of heating plants. Continuous gas pilot is not used. Automatic intermittent spark ignition operates for about ten seconds only, when, burner starts. Room thermostat controls on and off operation of burner. Controls safeguard Keating plant temperatures and pressures. Wear is automatically adjusted.' Fuel pump, may be had with oil level switch or stack safety control. trolled heating plant has permitted the development of a practical and in expensive, fully automatic domestic hot water supply system, which provides an inexhaustible supply of hot water at a very low cost. Complete description will be found in, "Oil Heating--What It Means to the Architect(See Catalogues). Operating Efficiency--Combustion efficiency in domestic heating systems, the equal of industrial power plant operation/ is obtainable with Oil-O-Matic. A test run by A. H. Hansen, Engineer, Metro politan Utilities, Omaha, reads: "Burner was tested for fuel con sumption, gas consumption for igni tion, and flue gases were analyzed for combustion efficiency. "Atmosphere was 29 deg. fahri, house was maintained at 72 deg. fahr. Burner operated 22 per cent of the time. Flue gas analysis--C02 12.2 per cent; O, 4.4 per cent; CO, none. Flue and combustion chamber was entirely free of soot." Domestic Hot Water Supply---The Details of this and many otker tests on mechanically fired, automatically con: request. 632 Williams Oil-O-Matic Heating Corporation Burners, Oil AiiAMvrir HEATING More Than 90,000 Satisfactory Installations Models--Oil-O-Matic Model J Type 1200 is designed for steam heating system serving 1500 sq. ft. direct steam radiation or less; hot water system serving 2500 sq. ft. direct hot water radiation or less; hot air furnace of 36 in. grate diameter or less. Model J Type 1800 is designed for heating systems larger than the model 1200. Will handle up to maximum of 4000 sq. ft. direct steam radiation; 6400 sq. ft. direct hot water radiation, or hot air furnace with maximum grate area of 14 sq. ft. New Oil-O-Matic Junior The recently announced Oil-O-Matic Model JR provide the most satisfactory heating for small residences and buildings.

Oil-O-Matic JR has a maximum oil capacity of 3 gallons per hour as com pared to the 5-gallon maximum of the Model J 1200. All Oil-O-Matic models may be installed in any type furnace or small boiler. All Oil-O-Matic oil burners operate on standard 110- and 220-volt 60 cycle A.C. or D.C. current as specified by you. Installation--Grates and ash pit door are removed. Ash pit door is closed with fire brick after Oil-O-Matic draft pipe is inserted, as illustrated. Contractor should also figure oil storage, consisting of 60-gallon tank, or other capacity, installed to comply with local ordinance; to be installed in basement; or a 1000 or 2000-gallon outside tank, buried not less than 3 ft. below grade and not more than 100 ft. from Oil-O-Matic; bottom of tank to be not more than 12 ft. below suction pump on burner. Installation must be made in accordance with Fire Underwriters' rules, city ordi nances and fire department regulations. Operation--Owner need only set room thermostat to desired temperature, turn on electricity--and forget all heating problems. Factory trained Williams service men are available most everywhere.
