Heating and Air Conditioning Systems Leader Boiler and Heater Company 176 West Adams Street, Chicago, Illinois "THE KOOLSTACK LINE"--Oil and Gas Fired Domestic Heating Boilers; Oil and Gas Fired Industrial Boilers; Oil and Gas Fired Warm Air Furnaces; Economizers for Oil Burners; Koolstack Air Conditioner. SUMMERAIR FURNACES--For Oil or Gas With the idea firmly in mind, that a successful heating unit is the one especially designed for the purpose for which it is to be used, this company has had extremely successful experience with the Koolstack line of Steam and Hot Water Boilers, fired with gas (either natural or manufactured) or fired with oil. The Summerair Furnace, aside from the casing, is a complete steel unit, electrically welded at all joints and free from any possibility of gas leaks. The furnace itself has.been raised from the floor to allow the utmost circulation of air. Because of their ease of installation they can be selected for replacement work as well as for new jobs. Other outstanding features of Summerair Furnaces follow: The counter-flow principle of heating the cold air in the tubes and around the economizer section. Equipped with our patented automatic chimney tem perature control damper. Scientifically designed and laboratory tested to present a minimum resistance to the natural flow of cold air through the unit. Summerair Furnace equipped with gas burner Entire design is circular in type, providing unrestrained heating action and easy installation of furnace outlets. Casing is provided with a radiant plate which greatly reduces casing loss. Can be furnished with Blowers, Filters and Humidifiers. \ """ Summerair Furnaces are made in three models. Heating surfaces from 83 sq. ft. to 108 sq. ft.; casing diameter from 36 in. to 44 in.; number of tubes from 8 to 12; height of flue cap 59 in. to 61 in. Send for bulletin giving full data. ` `KOOLSTACK' '--Air Conditioner Koolstack Air Conditioner has beeri designed to meet a demand for an economical, serviceable and efficient home air conditioning installation for steam, vapor or hot water boilers and warm air furnaces, when converted from coal to oil burning. Koolstack Air Conditioner consists of four sub-units combined into one instal lation. Each unit has been already proved efficient and the combination has been tested thoroughly under actual working conditions. The Koolstack Air Conditioner has been developed with a combination of ap pliances for utilizing the waste heat which would otherwise pass up the stack, filtering the air content and providing humidification with mechanical circulation. The unit can be installed on any existing oil burning plant without inconvenience or interruption in service. It occupies very little space, needing a floor space twenty inches by forty inches only. If more space is available the blower and filter cabinet can be installed as illustrated or it may be suspended above or near the heating plant. Specifications Economizer--Casing. Diameter, 20'.
