ATTENTION: For no reason must the re be ignited before the system has been completely lled with water; doing this would

lead to serious damage of the entire structure. The system must be lled by means of the loading pipe directly from the open tank

in a way to prevent an excessive pressure of the water network deforming the body of the thermo heating stove.

The system must be kept constantly full of water even during the periods when the use of the thermo-heating stove is not requested. During

the winter, inactivity must be faced with the addition of antifreeze.

4.2. CLOSED expansion Tank system

It is COMPULSORY that the CLOSED expansion Tank system is provided with:

4. CLOSED EXPANSION Tank can be installed on the thermo product return pipe. ATTENTION: The inside diameter of the return pipe

which connects the thermoproduct with the closed expansion vessel must be equal to the internal diameter of the return junction

present in the thermoproduct. The above mentioned connection pipe must be without siphoning parts.

5. PUMP CONTROL THERMOSTAT

6. NOISE ALARM ACTIVATION THERMOSTAT

7. NOISE ALARM

8. TEMPERATURE INDICATOR

9. PRESSURE INDICATOR

10. PUMP SYSTEM

ATTENTION: safety sensors must be in place on the machine according to that stated in chapter 4.1. All those parts must no have for any

4.3. ANTI-CONDENSATION MIXING VALVE - (purchased as OPTIONAL part)

The Anti-condensation mixing valve nds applications in solid fuel heat generators as it prevents cold water return in the

exchanger Picture 1 at page 52. Routes 1 and 3 are always open and, along with the pump installed on the return (R), they guarantee water

circulation inside the biomass boiler exchanger (CB). An elevated return temperature, allows efciency improvement, reduces formation of

smoke condensation and prolongs the boiler life span.

Valves on the market have different calibrations. La NORDICA advises use of model 55°c with 1” hydraulic connections. Once the valve

calibration temperature is reached, route 2 opens and the boiler water goes to the system via the ow (M).

IMPORTANT lack of installation of the device voids the heat exchanger warranty.

4.4. AUTOMATIC THERMAL DISCHARGE VALVE DSA (purchased as OPTIONAL part)

Solid fuel thermo products must be installed with safety devices determined by laws in vigour. For this reason the thermo products is

instructions or when it uses additional products not suitable for this device (see chapter Thermostatic Valve VAST TECHNICAL

DATA SHEET).

4.5. SYSTEM CONNECTION AND FILLING

Some examples, purely indicative of the installation, are reported at chapter INSTALLATION LAY-OUT, while the connections to the

thermoproduct are reported at chapter DIMENSIONS .

ATTENTION: The lling of the system must take place exclusively by the natural fall of the water from the open expansion tank

through the feed pipe in order to avoid that a too high water system grid pressure could change or cause the explosion of

boiler body.

During this phase, open all the bleed valves of the radiators to prevent the formation of air sacks, checking the outlet of water to avoid

unpleasant oodings.
