For other emission rates see SBI rating code. OIL and GAS BOILERS Dewey-Shepard's patented "Tube within a Tube" principle gives you 80 per cent or more heat absorption, resulting in pre-heating the incoming cold water before it comes in contact with the metal surfaces to which radiant heat is being applied. There is one square foot of heating surface for every gallon of water, transferring every possible unit of heat to the water, resulting in EFFICIENT, ECONOMICAL OPERATION . . . plus many other advantages for your customers, such as: LESS FUEL USED LOWER INSTALLATION COST*NO LIME--NO SCALE# 20 PER CENT LESS HEAT LOSS THROUGH THE STACK*NO EXPANSION, CONTRACTION OR CONDENSATION* CLEANEST HEAT POSSIBLE* SUFFI CIENT HOT WATER AT ALL TIMES DEWEY-SHEPARD'S NEW OIL FIRED "COUNTER FLOW" BOILER Designed for use with Baseboard Radiation, Copper Convectors, and Radiant Panel with forced circulation and small pipe sizes.

EconoTherm Models are fully automatic, self-contained, "packaged" units with full safety controls. Of 3-pass fire-tube design, they feature a modified Scotch Internal Furnace located off-center in the welded shell. Off-center firing creates a rotary water circulation, resulting in more uniform water temper ature, fast steaming, a steady water line at all times, and high quality dry steam. Higher water column above furnace pro vides greater safety, extra efficiency. Rotary combustion in furnace, large steam storage space, and five or more square feet of water heating surface per rated hp combine to deliver a guaranteed efficiency rating of 80 per cent with steam Available in 9 sizes, EconoTherm is a compact power "package.** Requires no heavy foundation or stack. dryness rating of 99 plus 0/0 dry steam under proper operating conditions. Induced draft fan pulls gases through boiler for positive draft and fast firing. Only a vent pipe is needed--no expensive chimney or stack! Boiler shell is onepiece welded construction, X-ray in spected, complying with all ASME requirements. Every unit . gets full running test and is accompanied with certified ASME Data Report. OTHER DUTTON TYPES These Include EconoMist automatic HRT with 5-way convertible firing (15 to 105 hp), EconoMaster verticals (5 to 60 hp), and EconoMlzer models (10 to 25 hp).
