The manual cycle is indicated on the display by the power bars. The power expressed in this cycle r mains always constant independently
from the power absorbed by the system. As always, the system's circulating pump is activated at the anticondensation temperature, that is
above 61° C.
In this case as well, a temperature ( ) can be set, above which the heater / boiler will operate at the minimum steady state power level. If an
excessive power level is set for the absorption of the system above the temperature of 80° C the heater / boiler will temporarily shut off and
the word STOP will appear on the display (6). Reactivation will occur automatically when the temperature drops to 68°C.

The appliance is equipped with a pressure transducer that allows you to check the water content level and pressure in the hydraulic circuit.
To view the boiler pressure press and hold down button (2) for 3 seconds until PH20 followed by the detected value appears on the display
for a few seconds.
If the circuit pressure drops to values that are too low, caused for example by a loss of fluid through tubes or other areas, the pressure
transducer detects a too-low pressure and communicates the fact through the PH20 alarm. In this case the appliance stops feeding pellets
and the smoke exhaust operates for a few minutes to discharge any combustion products. The alarm resets automatically if the pressure
returns to a value above 0.3 bar. The recommended pressure inside the boiler must be 0.8-1 bar. The pressure level must remain below 3 bar
because above this limit a safety valve calibrated at 3 bar trips and discharges the water under pressure (see hydraulic installation diagram).

Before using the heater / boiler check that all the movable parts are in place; also remove any labels and stickers from the glass to
avoid having permanent traces remain on the surfaces. Verify that the electric and hydraulic connections have been made
perfectly. Check also (during all the operating phases) that the firebox door and the ash pans are always firmly closed.
Then carry out the following operations:
- Check that the hydraulic system has been correctly executed and has an adequate closed expansion tank to guarantee maximum safety.
The expansion must be calculated as specified in UNI 10412/2. Any damage to the plant and/or appliance will not be covered by warranty.
The presence of the expansion tank in the heater / boiler guarantees protection against thermal expansion only and
exclusively of the heater / boiler.
- Power up the appliance and turn the switch installed at the back of the heater / boiler to position "1" (= ON).
- Fill the system using the inlet tap.
- Do not overdo the pressure in the appliance during the make-up phase : max pressure 1 bar. The reading of the pressure is executed as
explained in para. 5.10.
- The water fill phase must be simultaneous with the air purge. The purge operation is carried out using a screwdriver or a punch on the
purge valve (to accelerate the system filling times).
- Connect the smoke exhaust to the appliance : we recommend against using aluminium tubes and we recommend always using sealing
gaskets. Further information is given in paragraph 8 of this use and maintenance booklet.
- Load the pellets into the hopper .
CAUTION : a connection must be made
between the safety valve and the outlet to
prevent damaging materials surrounding the
boiler/heater when the valve is activated
(see hydraulic drawings).
