circulation of air at all times. We guarantee results. Bicalky Fan Company Buffalo, N. Y. New York Representative: D. T. Lyon, 39 Cortlandt Street Hot Blast System for a Church Building PLANT INSTALLED IN THE PLYMOUTH Most churches are inclined to look with more or less disfavor on the hot blast system of heating for two reasons: First, the cost of power to operate, together with the increased coal consumption; and, second, the expense and difficulty of obtaining a capable person to operate the system for the short time it is likely to be in use (generally about two or three days per week at the most). A notable departure from the general rule, however, has been made by the Plymouth M. E. Church of Buffalo, N. Y., which has not only a fresh air system, but an exhaust system as well. This church was built and recently completed by the J. H. Tilden Co., general contractors, the heating and ventilating work being performed by C. A. Criqui, of Buffalo. The architects for the structure are Cyrus K. Porter & Sons, Buffalo. The steam supply for the church is furnished by two "Ideal" S-48-9 boilers set in a single battery and piped up as shown in the basement plan, Fig. 1, and in the photograph. The basement is heated by direct radiators located and of the sizes shown in Fig. 1. These are all of the wall type and have the return pipes (not shown) run back below the water line of the boilers. On the first floor, the plan of which is shown in Fig. 2, direct radiators are used in combination with the fresh air system M. E. CHURCH, BUFFALO, N. Y. The fresh air system is operated by a hot air fan which is 150 in. in size with a discharge 451⁄2 in. by 67 in. and a wheel 78 in. by 43 in. It is driven by a belted PLYMOUTH M. E. CHURCH, BUFFALO, N. Y. 10 h. p. motor and delivers 23,000 cu. ft. of air per minute. The air is sucked in through a screen by the fan from the window directly in the rear and is driven out across the heating coils, where it is warmed by 6 sections of 20 rows of Vento coils (containing a total of 1,920 sq. ft. of radiation) which are set on iron beams.
