Operating instructions

Central heating temperature adjustment

The adjustment of the system water’s temperature in the

GASOGEN G3 2S boiler is obtained by rotating the knob in

position 32 in a clockwise direction to increase the temperatu-

re and in an antic-clockwise direction to lower it.

The temperature can be adjusted between 75°C minimum and

85°C maximum.

You can adjust the system water’s temperature in the back-

up oil/gas boiler via the knobs on the boiler’s control pa-

nel

Activation of the safety thermostat

IMPORTANT: The GASOGEN G3 2S safety thermostat’s re-

set is positioned on the front of the control panel.

The thermostat in position 31 reactivates the wood fired boi-

lers operation.

To gain access to it in case the boiler goes into lock-out, un-

screw the plastic cap with the help of a screwdriver; after ha-

ving reset it, replace the plastic cap.

The safety thermostat can intervene in case of boiler tempera-

ture overheating.You can avoid this happening by lowering the

working thermostat (see above).

If the boiler’s safety thermostat intervenes

often do not try to relight the boiler your-

self. Contact your nearest Unical authorized

After Sales Service Centre.

Central heating system pressure

If it is an open system design the pressure does not have to be

restored as this occurs automatically via the water level regu-

lator inside the water tank.

If it is a sealed circuit system (refer to local re-

gulations where this type of installation is per-

mitted), the pressure will have to be restored

via the mains connection cock, re-pressurizing

the system, when the boiler is cold,to1,2/

1,3 bar.

When the correct pressure has been reached, by checking

the value indicated in the pressure gauge installed in the

system, close the filling cock.

If you need to re-pressurize the system of-

ten we recommend you contact your nea-

rest Unical authorized After Sales Service

Centre.
