Danger!
Danger of death by poisoning and explosion because of breeches in the gas pipes and connections in case of
incorrect installation!
Installation of gas pipes is allowed to be performed only by an authorized agent. During installation all legal
stipulations, as well as the local regulations of gas distribution companies are to be observed.
When installing the gas pipe it is essential that it is not tensed so as not to create areas of leakage!
Caution!
Maximum safety pressure for the gas valve is 60 mbar! Going above this pressure limit may result in damage.
Work pressure with G20 natural gas functioning must be 20 mbar!
Gas pressure at the entry into the gas valve if GPL gas is used must be maintained between 30÷37 mbar!
Caution!
Is is obligatory to istall a pressure regulator on the fuel input circuit, adjusted at 20 mbar.
Caution!
In case parasite voltage appears on the gas pipe, it can be insulated by installing an electroinsulating piece
(according to the Technical Norms for the planning and execution of natural gas input systems).
Central heating boiler types
C32SPV24MEFB / C32SPV31MEFB / C22SPV23MEF
function on
GN
natural gas
.
The gas connecting
pipe is made of stainless steel with an interior diameter of 16.4 mm. The gas input pipe must not have a diameter smaller than
that of the gas connecting pipe of the central heating station.
The fuel input must be done according to applicable legal stipulations.

General directions for the heating installation
When designing the central heating system, please take in consideration the hydraulic characteristic of the pump that equips
this boiler model! See chapter 11 for pump characteristic.
Caution! Before connecting the central heating station carefully wash the entire heating installation! In this way, you
eliminate from the pipes various debris such as welding splashes, scoria, grummet, putty, dirt or similar. Otherwise,
these substances can form deposits in the heating switcher and can cause damage or malfunctioning.
Caution!
It is obligatory to install an impurity filter on the return of the thermal circuit installation!
When installing connecting pipes it is essential for these not to be tensed to avoid creating areas of leakage!
Maximum working pressure allowed is 3bar.
Recommended working pressure is 1.5 bar!
Caution!
It is forbidden to use the central heating station without thermal agent or partilally filled – danger of explosion!
It is forbidden to use the central heating station if it is not completely aired!
The equipment is provided with a 7l capacity and 1 bar loading pressure expansion vessel. Before installing the equipment,
check whether this volume is sufficient. If not, an additional expansion vessel must be installed on the aspiration side of the
pump.
Caution!
Check the pressure inside the expansion vessel before commissioning.
Pressure inside the expansion vessel must be 0.8÷1bar.
8.4
General directions for the hot water circuit
Connect the central heating station to the hot water installation.
It is obligatory to install filters to de-harden the water and a mechanical impurity filter on the cold water input
connecting pipe!
Caution!
When installing connecting pipes it is essential for these not to be tensed to avoid creating areas of leakage!
The apparition of pressure shocks (input pressures higher than 3-4 bars in addition to symoultaneously activating
quick closing taps) can affect the components of the hydraulic circuit inside the central heating station. We recommend the
installation of a pressure regulator adjusted to 3-4 bars!
Damage caused by the apparition of pressure shocks or by the use of higher pressure than recommended on the cold water
input circuit is not covered by the warranty!
We recommend the installation of a pressure regulator! Damage caused by the use of pressure higher than recommended on
the cold water input circuit is not covered by the warranty!
It is forbidden to install one-way valves on the the cold water input circuit.
The cold water input pipe of the hot water preparation circuit will always be open (closing the network is done only by
activating the taps at the consumer points) to allow take-over of possible dilatations on this circuit.
Note!
It is recommended that the distance between the hot water connecting pipe of the central heation station and the
nearest conumer is minimum 6m of pipe. Otherwiswe, there is always the risk of hot water burns.
