The domestic heating appliances with automatic feeding must: be supplied with a fuel block thermostat or be supplied with a
cooling circuit set-up by the appliance manufacturer.
The cooling circuit must be activated by a heat safety valve such to guarantee that the limit temperature set by the Standard is
not exceeded.
Connection between the power supply unit and the valve must be free from interceptions.
The pressure upstream from the cooling circuit must be at least 1.5 bar.
TYPE OF SYSTEM
There are two dierent types of system:
Open vessel system and closed vessel system.
The product has been designed and realised to work with closed vessel systems.
CLOSED VESSEL SYSTEM
System in which the water it contains is not in direct or indirect communication with the atmosphere. Generally, the closed
vessel system has one of the following expansion vessels:
Pre-loaded closed expansion vessel with membrane impermeable to the passage of gases.
Automatic closed expansion system with compressor and membrane impermeable to the passage of gases.
Automatic closed expansion system with transfer pump and membrane impermeable to the passage of gases.
Expansion system without diaphragm.
GENERALITY
The closed systems must have:
Safety valve
Pump control thermostat
Acoustic alarm activation thermostat
Temperature indicator
Pressure indicator
Acoustic alarm
Adjustment automatic circuit breaker switch
Automatic circuit breaker switch (block thermostat)
Circulation system
Expansion system
Safety dissipation system incorporated with the generator with thermal safety valve (self-activated), whenever the
appliance does not have a temperature self-adjustment system
SAFETY VALVES
The load capacity of the safety valve must allow the discharge of a quantity of vapour, not lower than: Q / 0.58 [kg/h] where: Q
is the useful outlet power to the generator water expressed in kilowatt. The diameter of the minimum net transversal section
of the valve inlet must not be lower than 15 mm. The valve load pressure, equal to the calibration pressure, increased by the
overpressure, cannot exceed the maximum exercise pressure of the heat generator. The designer must check that the maximum
pressure existing in every point of the system, does not exceed the maximum exercise pressure of its every component . The
safety valve must be connected to the highest part of the heat generator or outlet pipes, immediately near the generator. The
length of the pipes route included between the attachment to the generator and the safety valve must not be more than 1 m.
The connection piping of the safety valve to the heat generator must not be traceable and must not present, in any point, a
| ENGLISH

smaller section than the inlet of the safety valve or the sum of the inlet sections in case of more valves heading a single pipe.
The discharge piping of the safety valve must be realised in order not to prevent the regular functioning of the valves and
not to cause damages to persons; the discharge must ow immediately near the safety valve and be accessible and visible.
The diameter of the discharge piping must not however be lower than that of the outlet connection of the safety valve. For
diameter of outlet connection it is intended the minimum internal diameter on the valve outlet upstream of the eventual
internal threading.
CLOSED EXPANSION VESSEL
Warnings: check that the preload of the expansion vessel is set to 1.5 bar.
The vessel maximum exercise pressure must not be lower than the calibration pressure of the safety valve, increased by
overpressures, characteristic of the same valve, bearing in mind the eventual level dierence between vessel and valve and
the pressure generated by the functioning of the pump. The capacity of the expansion vessel/s is evaluated depending on the
total system capacity as results from the project. The closed expansion vessels must comply with the dispositions regarding the
planning, manufacturing, evaluation of conformity and use for pressure appliances. Intercepting objects or section decreases
must be inserted/practiced on the connection piping, which can be constituted by system portions. The insertion of a threeway intercepting valve which allows connection between the vessel and the atmosphere for maintenance operations, is
allowed. Such device must be protected against accidental manoeuvres. The connection pipe must be realised in order not to
present scales or deposits storage points. In case of more heat generators which feed the same system or the same secondary
circuit, each heat generator must be connected directly to the expansion vessel or system expansion vessels unit, altogether
dimensioned for the total volume of water contained in the same system or the same independent circuit. Where it is necessary
to separate the individual heat generator from the expansion vessel or expansion vessels unit, a three-way tap must be applied
on the connection piping between the generator and the vessel, in order to ensure, in every position, the connection of the
generator with the expansion vessel or with the atmosphere. The expansion vessels, the connecting pipes, the bleed pipes and
drain pipes must be protected from freezing, where this phenomenon occurs. The solution used for this purpose is described
in the design.
COMMISSIONING CHECKS
Before connecting the boiler:
a) wash all system piping in order to remove any residues which might compromise the correct functioning of certain system
components (pumps, valves, etc.).
b) check to verify that the ue has adequate draft, is not narrowed and that other appliances do not discharge into the ue.
This is to prevent unexpected power increases. Only after this control can the ue tting be mounted between the boiler and
the ue. A check of the connections with pre-existing ues is recommended.
AUTOMATIC THERMOSTATIC MIXER VALVE MANDATORY
The automatic thermostatic mixing valve nds applications in solid fuel boilers as it prevents cold water return into the exchanger.
Routes 1 and 3 are always open and, together with the pump
installed on the return, they guarantee water circulation
inside the biomass boiler exchanger.
An elevated return temperature, allows eciency
improvement, reduces formation of combustion product
condensation and prolongs the boiler life span.
Valves on the market have dierent calibrations. Extraame
advises use of 55°C model with 1" hydraulic connections.
Once the valve calibration temperature is reached,
route 2 is opened and the boiler water goes to the system via
the ow.
