Control and safety devices
Angus Evo boilers are equipped with three main control elements:
A
chimney flap (Fig. 05)
, by means of which the chimney thrust can be controlled, i.e. the discharge of combustion fumes into
the chimney. The flap is situated in the flue neck of the boiler, and is controlled manually.
fig.05
Another thrust control element is a
thermo-mechanical output regulator (Fig. 06)
. It is situated on the outlet from the boiler
cast iron body. It detects temperature of the hot water and regulates the supply of primary combustion air to underneath the boiler
stoker, by opening or shutting a flap situated in the ashtray door.

When fitting the safety and the control elements remember to meet the principles of work safety.
■
If replacing of safety device and of thermo-mechanical output regulator is necessary, please use
recommended devices in case of using any other type of the device negotiate with Eco Angus Ltd.
■
Functionality of thermo-mechanical output regulator (satrom) must be checked or inspected by
authorised person once in a year.
Changing the hatch position controls the combustion intensity and thus the boiler output. The thermo mechanical output regulator is
connected with the regulating hatch by chain. The chain is connected to the hatch in such a way that its tension can be set
