6 OPERATION
6.1 Hydraulic system
The hydraulic system and the appliance itself must be connected by qualified personnel in compli-
ance with laws and regulations in force in the country (in Italy ref. D.M. 1/12/1975 and UNI 10412-2). The
hydraulic connection to the appliance must be made before the upper part of the casing and the
outer hood are installed.
1.
Before installing the casing, perform the hydraulic seal test on the pipes connected to the
appliance.
2.
Make sure that all control and safety devices, including those supplied as standard, have been
installed correctly.
Make sure that, when the stove is in use, all conditions allowing the system to absorb the
heat generated safely are in place.
MAIN CIRCUIT: OPEN CHAMBER
MAXIMUM SECONDARY CIRCUIT PRESSURE: 2.5 bar
DO NOT INCLUDE any room thermostats that stop or start the circulation pump in order
to regulate the temperature in rooms. For safety reasons, the pump must ALWAYS operate
for as long as the stove is burning fuel, to dispose of the heat generated in the Termopalex.
If the rooms are too hot, reduce the size of the fire, even letting it go out if necessary.
Never exceed the maximum recommended load of wood fuel indicated in the product booklet.

Connection to the water circuit
The stove is connected to the water circuit at the
following points:
• Hot water delivery to secondary circuit (I)
• Return from secondary circuit (J)
• Mains water inlet (N)
• ACS mixing/delivery valve (P)
• Expansion chamber discharge (O)
• Secondary circuit filling/emptying (L)
• Secondary circuit safety valve discharge (K)
• Appliance boiler discharge (H)
Probe connection
Connect the two probes of the temperature
controller (S1 and S2). Insert S1 in the housing
(M) on the fireplace. Place S2 on the secondary
return pipe, near the shut-off valve (S).
Digital temperature controller (ACS)
configuration
Set the digital temperature controller according
to “system diagram n°17”.
