be electrically connected to a thermostat or a electronic control unit that can be purchased with the thermo-fireplace as OPTIONAL part.
8. ANTI-CONDENsATION MIXINg VALVE – (see chapter)
ATTENTION: temperature safety sensors must be in place on the machine or at a distance no greater than 30 cm from the flow
connection of the thermo-product. Whenever the thermo products lack a device, those missing can be installed on the thermo
product flow pipe, within a distance no greater than 1m from the thermo product. All those parts must no have for any reason
meditate intercept bodies that could accidentally exclude them and must be placed in rooms which are protected from frost. On
the contrary, if they freeze, the boiler body could break or even explode.
ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water; doing this
would lead to serious damage of the entire structure. The system must be filled 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.
CLOsED EXPANsION TANk sYsTEM
It is COMPULsORY that the CLOSED expansion Tank system is provided with:
1. A sAFETY VALVE - maximum operation pressure allowed for the system is : see DECLARATION OF PERFORMANCE - CE MARKING
INFORMATION. Higher pressures can cause deformation and breakage of the boiler body. ATTENTION: The inside diameter of the
supply pipe which connects the thermoproduct with the security valve must be equal to the internal diameter of the supply junction
present in the thermoproduct. The above mentioned connection pipe must be without siphoning parts.
2. ANTI-CONDENsATION MIXINg VALVE – (see chapter)
3. AUTOMATIC THERMAL DIsCHARgE VALVE DsA or TEMPERATURE sAFETY RELIEF VALVE, with double safety sensor
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.

ATTENTION: temperature safety sensors must be in place on the machine or at a distance no greater than 30 cm from the flow
connection of the thermo-product. Whenever the thermo products lack a device, those missing can be installed on the thermo
product flow pipe, within a distance no greater than 1m from the thermo product. . All those parts must no have for any reason
meditate intercept bodies that could accidentally exclude them and must be placed in rooms which are protected from frost. On
the contrary, if they freeze, the boiler body could break or even explode.
IT Is MANDATORY that the thermo products for domestic heating inserted in CLOsED Tank heating systems, must be internally equipped,
with a cooling circuit, prepared by the unit manufacturer, which is activated by a thermal safety valve (see chapter VAsT) which does not
require auxiliary power and can guarantee that the standard set temperature limit is not exceeded. Connection between the power supply
unit and the valve must be free from interceptions. Cooling circuit upstream pressure must be at least 1,5 bar.
ANTI-CONDENsATION MIXINg VALVE OBLIgATORY (PURCHASED AS OPTIONAL PART)
The Anti-condensation mixing valve finds applications in solid fuel heat generators as it prevents cold water return in the exchanger (chap.
DIMENSIONS). 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 efficiency improvement, reduces formation of smoke condensation
and prolongs the boiler life span.
Valves on the market have different calibrations. Dal Zotto 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 flow (M).
IMPORTANT lack of installation of the device voids the heat exchanger warranty.
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 equipped
with a heat discharge coil.
The heat discharge coil must have one side connected to the water network (chap. DIMENSIONS / chap. DIMENSIONS - A) and the other
rot drainage network (C). When the safety temperature is reached, the automatic thermal discharge valve DSA, the bulb of which is to be
connected to attachment B, enables the intake of cold water in the boiler coil, discharging the excess heat out of pipe C towards a conveniently
installed drain. Cooling circuit upstream pressure must be at least 1,5 bar.
WARNINg: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions of
these instructions or when it uses additional products not suitable for this device (see chapter Thermostatic Valve VAST
TECHNICAL DATA SHEET).
