Fountain-Style Brick Masonry Heater
This may be achieved by providing a 16-in. (400 mm) extended hearth. In the front of the heater, a minimum 20-in. (500 mm) extended hearth should be used. This is easily achieved when the heater is properly positioned in the room for maximum heating. This position is in the center of the room so that all four brick walls of the heater are providing radiant heat to the room.
The brick masonry heater should always be positioned entirely inside the building. It should never be incorporated into an exterior wall, because much of the radiant heat would be lost to the exterior. In addition to this heat loss, the location on the exterior wall will usually result in at least one cold surface on which a considerable amount of creosote may form. A creosote fire may well result in sufficient damage to the heater so that it is no longer safe to operate.
