The bracket which has a U-shaped cross-section corresponding to one channel is formed of two lateral faces and a joining face provided with a perforation suitable for hanging a ceiling fixture.

Abstract: A warm air heating system which efficiently and inexpensively combines a fire-place to another warm air heating device or unit to form a balanced warm air heating system and thus efficiently use the heat output of the fire-place. This warm air heating system comprises an air plenum housing and a fire-place; the air plenum housing includes air ducts, an air blower, an air flow distribution valve, an electric heating device, an actuator for the valve, and air inlets and outlets and the fire-place includes an air heating space and is connected to the air plenum housing with a thermostatic control for the actuator. Therefore, upon heating of the fire-place, more air will be circulated through the fire-place by proper operation of the valve by the actuator and less air will be heated by the electric heating device to efficiently use the heat output of the fire-place.
