Chain thermostat installation (STANDARD VERSION)
ECOWOOD STANDARD is equipped with an air door on the
lower part and is delivered with chain thermostatic
regulator.
Install the regulator at the connection pipe on the upper
side of the boiler and pass the chain through the hook
provided on the air door.
Choose the desired boiler temperature from the
thermostat head (red scale is valid).
The thermostatic regulator controls the boiler temperature
by controlling the supply of combustion air. The chain
length must be adjusted so that when the set temperature
is reached the air door is in closed position and no air is
supplied.
