In theheating section there are a combustion chamber and a heating exchanger. Theinsulating mattress is protected in this area by galvanized sheet iron, against theoverheating dangers. Under the combustion chamber, in the ventilating section, isassembled a centrifugal fan with double suction (galvanized), driven by an electric motor.A hands protection grate with holes 10x10 mm. is provided in the ventilating unit. Thegrate is screwed on the frame and can be removed only with the help of a tool. Thecombustion chamber, built in stainless steel for high temperatures is bolted on the frame,so that its thermal expansions don’t influence the long life. The heat exchanger, built withnormal steel pipes, is strongly welded to the combustion chamber. Inspection andmaintenance operations may be carried out through large openings on them.

In the low ventilating section there is a control board with:

- Main switch - commutator "HEATING-STOP BURNER-VENTILATION" - Voltage light - .

The warm air heater is equipped with a combination of 3 thermostats placed on the heatexchanger, assuring the following control and safety functions:

- )$1� thermostat normally opened, to start and stop automatically the ventilatingunit during "HEATING" phase (calibration at 30°C).

- /,0,7�75�� temperature limit thermostat for the burner, normally closed, to stopthe burner, when the outlet air temperature goes over the calibrate value. It resetsautomatically the burner, when the air goes cooler (calibration at 80°C).

In locating heaters, consider general space-heating requirements, availability of gas, andproximity to vent locations. Heaters should be located so heated air streams wipe exposedwalls without blowing directly against them. In multiple unit installations, arrange units sothat each supports the air stream from another, setting up circulatory air movement in thearea. In buildings exposed to prevailing winds, a large portion of the heated air should bedirected along the windward wall. Avoid interference of air streams as much possible.

If the room has air extractors, locate the heater in the opposite wall and provide for air inletgrills to reintegrate air.
