Page 80 - The size of the largest riser should usually be limited to 2^" in school and dwelling house work unless it is a special pipe carried up in a concealed position. If the length of riser is short between the lowest radiator and the main, a higher velocity of 20 feet or more may be allowed through this portion rather than make the pipe excessively large.
Page 168 - ... similarly occupied require that more heat shall be supplied to some than to others. Rooms that are on the south si.de of the building and exposed to the sun may perhaps be kept perfectly comfortable with a supply of heat that will maintain a temperature...
Page 62 - Overhead coils are usually of the miter form, laid on the side and suspended about a foot from the ceiling; they are less efficient than when placed nearer the floor, as the warm air stays at the ceiling and the lower part of the room is likely to remain cold. They are used Fig.
Page 38 - A room in a grammar school 28 ft. by 32 ft. and 12 feet high is to accommodate 50 pupils. The walls are of brick 16 inches in thickness; and there are 6 single windows in the room, each 3 ft. by 6 ft. ; there are warm rooms above and below; the exposure is SE How many BTU will be required per hour for warming the room, and how many for ventilation, in zero weather, assuming the building to be of average construction?
Page 14 - Where the boiler is used for heating purposes only, a low steam pressure of from 2 to 10 pounds is carried and the condensation flows back by gravity to the boiler which is placed below the lowest radiator. When, for any reason, a higher pressure is ,, required, the steam for the heating system is made to pass through a reducing valve and the condensation is returned to the boiler by means of a pump or return trap.
Page 114 - A single riser is carried directly to the expansion tank, from which branches are taken to supply the various drops to which the radiators are connected. An important advantage in connection with this system is that the air rises at once to thejexpansion tank, and escapes through the vent, so that air-valves are not required on the radiators.

Page 94 - J-inch mesh; to this are fastened flaps or checks of gossamer cloth about 6 inches in width. These are hemmed on both edges and a stout wire is run through the upper hem which is fastened to the netting by means of small copper or soft iron wire. The checks allow the air to flow inward but close when there is any tendency for the current to reverse. The area of the cold-air duct for any heater should be about three-fourths the total area of the warm-air ducts leading from it.
Page 113 - Figs. 91 and 92, the latter form being used where the headroom is limited. The connection from the heating system enters the bottom of the tank, and an open vent pipe is taken from the top. An overflow connected with a sink or drain-pipe should be provided. Connections should be made with the water supply both at the boiler and at the expansion tank, the former to be used when first filling the system, as by this means all air is driven from the bottom upward and is discharged through the vent at...
