IriTERn/mon/lL Onepipe Heater 



THE-ONEPIPE or, as termed by many manufacturers, the 

 "pipeless" heater is the most modern development of the 

 warm air heating system, and we unhesitatingly recom- 

 mend the INTERNATIONAIi ONEPIPE HEATER as one of «ovi>, 



the most practical, durable and efficient heaters of this type 

 on the market. 



Before trying to decide on the kind of heater to buy, we 

 recommend that you get the advice of our engineer, for it is 

 a fact that no two houses are exactly alike, and each one 

 presents an individual problem. 



INTEBHTATIONAI. ONEPIPE HEATERS are adapted to 

 many city houses as well as to country homes. They are 

 especially efficient in bungalows and the square type two- 

 story houses with open stairways. They are ideal for heat- 

 ing churches, stores, etc., because of the recirculating fea- 

 ture which takes the cold air from the floors. Because of 

 their low installation cost they are frequently placed in 

 summer camps and cottages that are occupied in spring and 

 fall and for week-end parties in the winter. 



The INTEBNATIONAIi ONEPIPE HEATER is simply a device for heating the air 

 and causing it to circulate through the rooms. It is essentially the same as a regular 

 INTERNATIONAL Warm Air Furnace — not a stove, but a furnace, properly designed to 

 get the greatest benefit from the fuel burned, and all parts carefully mounted and fitted. 

 Surrounding this are two casings, an inner and outer casing, and on top you can see the 

 register. 



This heater uses only the one large register, which is divided into two parts. It is 

 a well-known fact — as old as nature itself — that air when heated expands and rises. As 

 the warm air pours up through the central portion of the register it goes at once to the 

 ceiling of the various rooms and floods the whole house with warmth. 



This warm air displaces the cooler air, which falls to the floor and is then drawn 

 down through the outer portion of the same register, between the outer and inner casings, 

 and is then rewarmed and recirculated. This will be understood by carefully following 

 the direction of the arrows in this picture. 

 As the space between the outer and inner casings is always filled with the cooled air returning to be heated, an INTEB- 

 NATIONAII ONEPIPE positively does not heat the cellar. This is a big advantage and does away with the objection fre- 

 quently raised against ordinary warm-air furnaces in the country or in fact, anywhere the user wishes to store fruits, vege- 

 tables or anything of a perishable nature in the cellar. If the doors between rooms are left open, the heat diffuses through 

 the whole house. The skeptical can easily test this by igniting a piece of tarred paper or oily waste over the register, and 

 noting how the smoke fills the rooms. Remember that the heat that you cannot see, but can feel, travels in just the same way. 



No one who has ever tried a Onepipe Heater would think of again using stoves. It not only heats more effectively, but 

 being in the cellar, does not take up any valuable space in the living rooms. Then you do away with all litter and bother 

 of carrying coal and ashes through the rooms. A stove heats in spots only. It is uncomfortably hot near it and uncom- 

 fortably cold at a distance from it. * 



THE CASING 



GALVANIZED IRON CASING 

 JLINED WITH 2THICKWESSE5 

 loF ASBESTOS PAPER 

 rAND CORRUGATED TIN 



The feature that distinguishes the INTEBNATIONAII ONEPIPE HEATER from stoves, ordi- 

 nary furnaces and all other Onepipe, or so-called "Pipeless" heaters, is the construction of its 

 casing. The castings are surrounded by two casings or "jackets" — the heated air passes up in- 

 side of the inner casing while the cooler air is returned between the inner and outer casings. 

 Both of these are made of rust-resisting galvanized iron and they are so shaped that there is 

 not a single sharp angle or dead pocket to obstruct the free and easy flow of air. 



The inner casing is in one piece and carried right down to the base and openings are cut in 

 it through which the air circulates. This construction is much more stable than where this 

 part is set up on legs. 



The inner casing is triple lined — (you will understand what we mean by this if you will refer to the little diagram shown 

 on this page. Inside of the galvanized iron are placed two thicknesses of asbestos paper and one thickness of bright corru- 

 gated tin — these are all securely riveted together. The purpose of the corrugations is to provide a layer of air which, in 

 connection with the asbestos paper and corrugated tin make an effective insulation to keep all the heat inside the casing 

 where it is needed. Contrast this durable heavy construction with a common type of inner casing made of cheap black iron 

 with a single asbestos lining pasted inside, or with a secondary lining of black iron.

 are always sent unless 

 otherwise ordered. 



A deduction from the

All Double Door Heaters measure 7 feet 11 inches from base to register, but ex- 

 tension pipe telescopes, so as to fit without cutting, as low as 6 feet 11 inches. Spe- 

 cial measurements can be furnished to order, when distance from basement floor to 

 top of first floor is given. 



Every Onepipe Heater is shipped complete with casings and electroplated register; 

 and including also one galvanized smoke pipe elbow, one joint of smoke pipe and 

 damper with regulator and chains so that it can be operated from the floor above.
