Spencer Automatic Magazine Feed Heaters are made in cast-iron sectional types for steam, vapor and hot water heating. Also in steel tubular types for larger buildings. There are sizes and capacities to provide economical and convenient heat--safe and sure --for every type of building. Spencer is the original magazine feed heater with a record of more than 37 years' successfuPoperation. They are sold and installed by all good heating contractors. fuels; or the steel magazine feed heaters, also for No. 1 Buckwheat. Coal - Coke - Gas - Oil--Spencer J'and L series cast-iron and steel tubular heaters are primarily designed to burn low cost No. 1 Buckwheat anthracite and the C-N series Nut or Pea anthracite or coke. If at any time a home owner desires to burn more expensive fuels--oil or gas-- a Spencer Heater will show a higher efficiency than can be secured with any ordinary boiler. Thermostats--A Minneapolis thermo stat and electric damper motor are fur nished as optional equipment. Jacketed Covering--Attractive metal lic jackets, as illustrated are available for Spencer Cast-Iron Heaters. Why Spencer Heaters perform so satis factorily can best be explained by a brief inspection of their design and construction. The Spencer principle--as illustrated in the cross sectional view--is simple: Once a day fuel is put into the magazine (A). It fills the sloping grate to the level of the magazine mouth (B). The fire bed always stays at (C) for as fast as fuel bums to ash (D) it shrinks and settles on the sloping grate (E) and more fuel feeds down automatically over the top of the fire bed. Fuel feed is by gravity alone, in just the right amount to keep the fire always burning at its most efficient combustion point. This explains why a Spencer Heater. always gives the same uniform satisfying heat, and bums low cost coal economically. These exclusive Spencer advantages are available in all types, J and L series, castiron sectional, burning low cost No. 1 Buckwheat; the C-N series for larger . *The Spencer Heater Company guarantees that when installation is made in accordance with accepted standards, the heater will carry the number of feet of direct cast-iron column radiation listed. This allows ample provision for heat loss in covered mains, risers and returns, and for peak loads. 872 Spencer Heater Company Boilers, C. I. and Steel Tubular SPENCER STEEL TUBULAR MAGAZINE FEED BOILERS For larger buildings we recommend Spencer Steel Tubular Boilers, also of the nmgazine feed type, burning low cost No. 1 Buckwheat anthracite or coke. In the cross-section diagram illustrated here, part of the fire bed is cut away to -show the sloping grates and the two maga zines filled with fresh coal, ready to feed down automatically of its own weight to the fire. These boilers are built in two vertical sections for ease in handling and installation--a great advantage on re modeling or replacement jobs, eliminating necessity of costly tearing out of walls, etc. Combination water tube and fire tube construction. Built to .4 .S.M.E. standards. SPENCER STEEL BOILERS, FOR OIL, STOKER OR GAS For more than 37 years Spencer has been building efficient, econo mical and depend able coal burning boilers. With this background of ex perience, Spencer engineers have developed the Spencer Steel Boiler, for oil, gas or stoker. The high sus tained efficiency of these boilers means adequate heat for low fuel cost., Design is of the three-pass type. Combustion chamber is amply large. Built of open hearth steel boiler plate and electrunite tubes--a quality product for dependable service. Furnished with Taco indirect domestic water heating coils either of the storage tank or instantaneous type.
