Single G-E FEATURES: The new G-E Oil Furnaces are extremely compact units for a given capacity . . . lower in co st . . . easy to in s ta ll. Quicker steaming because of high heat transfer rate and low water content -- (steam s within 2 or S minutes after thermostat calls for heat). G-E Flam e Detector provides complete shut-down within 5 seconds in event o f flam e fail ure. G-E Master Control-Telechron motorized for a posi tive, tim ed op eratin g se quence. Fine Atomization -- 100,000,000 particles from every drop o f oil -- plus G-E Inverted Flam e insures complete com bustion. Flam e shoots down, then is turned back upon itself. In the G-E Heat Trap, the hot gasses are literally trapped in the furnace until their heat is absorbed, they then pass out through the flue connection at the bottom o f the furnace. G-E OiJ Flow Stabilizer maintains constant oil rate essential to high fur nace efficiency. G-E Oil F ur naces have proved extremely economical in operation. Completely automatic. Selfoiling motor for long-lived, carefree operation. Two-try re-start mechanism attempts to start furnace twice before complete shut-down. (See your A.I.A. File No. 30-C-l.)

Coils have copper tins, Electro-Therm ally bunded to copper tubin g to m aintain high heat transfer efficiency. Copper return bends are silver brazed to tubing. Sturdy steel tube sheet serves us cumpuct end casing and m ounting tlunge. Coils are especially designed for mount ing in housing or ducts, and can be bolted together to form a continuous, unbroken surface. From top to bottom and from end to end, the face area o f G-E coils is 100'X- effective, with no waste space taken up by supports, braces or casings. A condensed table o f sizes is given below; they are also available in 2 in. steps o f coil length so that it is seldom necessary to alter plenum chambers or housings to accom m odate G-E coil su rface. All coils built by special machinerv in General Electric factories. Descriptive bulletins and full application data now available on each line o f coils. DIRECT EXPANSION COILS For Cooling and Dehumidification with Freon-12 Refrigerant Built for direct expansion o f refrigerant, these coils represent the ultimate in flexibility and adaptability to sum m er air conditioning system s.
