Danfoss Model ESBE ATA102 Draft Regulator

Application:
The ESBE Draft Regulator is a self contained thermostatic expansion control device intended to regulate the temperature of solid fuel fired boilers without requiring any electrical installation or complicated linkage. The thermostatic control head senses the boiler temperature and the air damper position, controlling combustion air flow. The ESBE Draft Regulator isfully adjustable within the range of 100 - 195 °F (40 - 90°C). Connection is through ascrewed boss directly into the boiler waterway.

Mounting:
The regulator may be mounted either vertically or horizontally with the chain connected to the air damper with the lever and chain adjusted so that the air damper just closes when the required temperature has been achieved. Fine adjustment of boiler temperature is made by rotating the control knob, each graduation of the knob corresponds to 50 °F (10 °C) dependent on operating range.
