.378 Heating System* PETRO 3242 West 106th Street, Cleveland 11, Ohio Quality Heating and Power Equipment since 1903 INDUSTRIAL AND COMMERCIAL OIL AND GAS BURNING SYSTEMS FOR EVERY NEED LARGE CAPACITY BURNERS, MODELS P-90, P-90E, P-200, P-200Et In addition to domestic heating in large residences, these Petro burners have a wide field of application in many commercial and public buildings such as schools, churches, stores, garages, and apart ments. Model P-i "PACKAGED" COMMERCIAL OIL BURNERS--FOR FUEL OILS UP TO AND INCLUDING HEAVY NO. 5 Here at last is a reliable pin type low pressure Burner that will fire No. 5 oils or any lighter grade, using the superchargertype fuel atomizer. Atom ization is so complete that electric ignition can be used in place of the gas flame required by other burner types. The ability to fire heavy or light oils, and to modulate over a wide range, makes this burner unique in its field. Capac ities are from 3 to 25 gph.

Burners are available in two types of construction: fan housing above or below the draft tube. Models with fan housing below the draft tube are particularly adaptable to Scotch-Marine type boilers, as no burner parts project above the draft tube to interfere with boiler cleanout doors. Installation is simple. Capacities range from 8 through 24 gph for oil and for gas from 1,200,000 through 3,600,000 Btu input This Petro package unit is much more than a conversion burner. It's a complete combustion system in which all elements are cor rectly balanced and integrated--a thoroughly engineered firing plant. Includes burner (for oil or gas or bom), fuel system, forced draft air supply, control panel, and pro-formed refractory com bustion throat Installation requires little more than bolting the entire unit to the boiler-front and making service connections for power and fuel; This represents a substantial saving in in stallation time and cost--but even more important it means a factory tested and assembled unit for high operating efficiency, and fuel savings. Control panel is totally enclosed, with all instruments wired and tested at the factory.

It is a fully integrated unit in which primary air for com bustion of both oil and gas is supplied by the oil burner fan. Secondary air is admitted around the burner opening, eliminating the deep firebox pit and brick checkerwork required in the con ventional rotary oil burner setting. Enclosed control panel, with instruments installed, wired and tested at factory, may be mounted at burner or on boiler room wall. Fuel change is ac complished quickly by electrical switching. Oil capacities, 11 to 120 gph; gas l,650,000.to 18,750,000 Btu input. Model WC Burner Combination gas-oil, with Petro rotary oil burner (direct or belt drive) integrated with gas burner, air register and pre-cast refractory combustion throat ModuOvI Bn centred added if desired. Complete gas-oil firing system in single New Air Register Readily converts any Petro Rotary Oil Burner to combination gurofi firing. Kit includes register, gas controls and standard parts groups. A minimum of installation time required. Air regis ters available also for straight o3 firing. INTEGRAL AIR REGISTER CONVERSION KITS: ^ The Petro Air Register is ideal for converting oil installations to gas-oil. The rotary oil burner bolts on the register making an easy field conversion that is complete with refractory, combustion throat and the gas ring. All combustion air is admitted around the burner opening as required by Underwriters' Laboratories standards. All Petro Model W burners are available in either direct- or belt-driven motor type*.
