djustment only a few times during the heating season. (d) A direct-draft or by-pass damper, which is pro-vided in many heaters (Fig. 2) to make possible, when de-sired, the direct passage of smoke from the fire box to thesmoke outlet, thus cutting out the tortuous flue passages instarting a fire or until the chimney is well warmed, and agood draft has been established. This damper must not beleft open except for a short time; otherwise a great wasteof fuel will result. (7) The grate is the most important single item in the entireheating plant. The amount of heat which can be developed andtransmitted to a heat distributing system having a suitable chimneydepends directly upon the amount of coal that can be burned in theheater, and this, in turn, depends upon the construction and area ofthe grate. In order to get more heat it is necessary to burn more PURCHASE AND USE OF COAL FOR HEATING HOMES 11 Dasemenf Ceiling Damper regulatorof steam? type Damper chain Clean - oaf door(a/r tight/, v

Note—Many boilers do not have a by-pass damper, a device which should be open onlywhen starting a fire.
