.. Industrial Heating AiT Conditioning Direct-Sired Heaters LENNOXIndustries Inc. 1701 East Euclid, Des Moines 4, Iowa Representatives Is All Principal Cities FOR SPACE HEATING, DRYING, MAKE-UP-AIR AND OVEN APPLICATIONS 1. Adjustable air discharge nozzles per mit directional heating or attachment to a duct distribution system. 2. Stainless steel combustion chamber. Four pass counter flow mode of heat transfer without the use of internal baffles. 3. Economizer section: Boiler tubes equipped with high velocity retarders contribute to operating efficiency of 80 percent or better. 4. Double casing with metal radiation shield retards casing heat loss. 5. Quiet, heavy-duty, belt-driven blow ers mounted on adjustable rails for easy adjustment. Large blower compartment reduces inlet velocities and drafts. 6. Burners are oil, gas or combination fuel--all interchangeable. A combination burner also available for quick change from gas to oil-firing without removal of any burner parts. 7. Heavy-duty safety door equipped with self-closing latches; observation port for e8a. sIyndfleapmeendinesnpteinctdiounc.ed draft blower eliminates need for chimney-type draft. 9. Main switch shuts off all power at heater; all sequencing provided by one master controller, protects against flame ignition, power or draft failure; no cold surge at start-up. engineering data Air Conditioning SSSSfeglgSg Mammoth Furnace Company 6425 Cambridge Street Minneapolis 26, Minnesota Commercial'di^ Strong--built for rugged service and safe shipment. Quiet Fan Operation--a rigid tubular fan shaft supported by two self aligning bearings eliminates shaft and bearing problems. Retractable Burner Tray--allows com plete service to burner. Permits removal from unit with no disassembly and mini mum handling. Centra] Control Cabinet--provides con trols, fusing and wiring in an accessible dust-tight enclosure. Direct Driven Induced Draft--troublefree, vortex cooled motor shaft connec tion to blower wheel. No belts and addi tional bearings to service. Variety Of Controls And Power Supplies --units may be "off-on" thermostat con trolled, hi-low fire or modulated control. Wiring and controls can be provided for all power supplies. Integrated Burner Applications--burners by reputable manufacturers are tailored to produce the most effective flame con figuration for the heater design. Combustion Safety And Draft Controls-- MH-EIectronic flame control system, pre-ignition draft purge timing and draft sensing give a high degree of operation safety.
