Publications American Society of Heating and Ventilating Engineers 29 West 39th Street, New York THE CODE OF MINIMUM REQUIREMENTS for the HEATING AND VENTILATION OF BUILDINGS (Edition of 1929) $5.00 per Copy The Code has been recently published by the American Society of Heating and Ventilating Engineers, New York, in fourteen sections, bound attractively in a loose leaf holder. Each section was prepared by a SubCommittee and the following subjects are covered: Section I--Minimum Ventilation Re quirements for Public Buildings. Section XI--Minimum Requirements for Estimating the Heat Required for Warm Buildings. Section III--Minimum Requirements for the Determination' of the Amount of Direct Steam and Hot Water Radiating Surface to be installed in Steam and Hot Water Heating Systems. Section IV--Minimum Requirements for the Determination of the Amount of Indirect Steam or Hot Water Heating Surface to be Installed in Indirect Gravity and Fan Circulation Heating and Ventilating Systems. Section V--Minimum Capacity and In stallation Requirements for Low Pressure Steam and Hot Water Heating Boilers. Section VI--Minimum Requirements for the Design and Installation of Warm Air Furnace Heating Plants. Section VII--Minimum Requirements for the Design and Installation of Chimneys or Stacks for Steam Boilers, Hot Water Boilers and Warm Air Furnaces. Section VIII--Minimum Requirements for Pipe Sizes for Use with Low Pressure Steam, Vapor and Vacuum Heating Systems. Section IX--Minimum Requirements for Pipe Sizes for Use with Gravity and Forced Hot Water Heating Systems. Section X--Minimum Requirements for the Design and Installation of Air Ducts, Inlets and Outlets, in Conjunction with Fan Air Circulation, and the Installation of Ventilating Fans for Use with Steam and Hot Water Heatingand Ventilating Systems. Section XI--Minimum Requirements for the installation of Air Washers and Filters. .Section XII--Pumps for Heating and Ventilating Equipment. . - Appendix I--Formulae for Physical Units,' Air and Vapor Mixtures, Etc. Appendix II--Standard Symbols for Heating and Ventilating Drawings. , The Code consists of 158 pages and is fitted into a loose leaf binder with black flexible cover. It is printed on India Tint stock, 6x9 inches in size. The Code of Minimum Requirements was developed as a result of numerous requests made to the Society by engineers, architects, municipalities, engineering and trade or ganizations and its purpose is to standardize as far as practical the installation of heating and ventilating equipment. ' . The Code represents minimum require ments as called for by good engineering practice and is so written that it. may be incorporated as a part of a Municipal Building Code, if found desirable. 752 .4i it 3 Pumps American Steam Pump Company Plant and General Offices: Battle Creek, Michigan NEW YORK: 17 Battebt Place CHICAGO: 926 Monadnock Bldg.
