This comp ny will ssume responsibility for the correct inst ll tion nd commissioning.
8.1.1 Inst ll tion directions
The central heating station will be subject to corrosion from the moment it is filled with water!
To receive warranty during the entire warranty period it is essential to take into consideration the following directions in order
not to increase the corrosion!
- The burning gas must have the sulphur content within the limits of the applicable European standard: it is accepted for a short
period of time to have a maximum of 150 mg/m3, but the yearly average must be of 30 mg/m3.
- The burning air must not contain chlorine, ammonia, alkaline agents, halogenated hydrocarbs, freon, plaster particles, lints,
dirt or dust;
- Installation of the central heating station in the proximity of a swimming pool, washing machine or cleaner can result in the
contamination of the burning air with these compounds.
- Water pH must be within the following limits: ,5<pH<9,5
- It is recommended to check the w ter nd therm l gent pH frequently nd if the v lue does not f ll within the limits provided
by the m nuf cturer, it will be tre ted g in.
- Water asperity must be within the limits 5°F <TH <15°F (5°F (French degrees), equivalent to 50 mg CaCO
3
or an equivalent
quantity of other Ca and Mg salts).
- It is recommended to have repeated station startup cycles with the fuel tap off in order to air the installation.
- If the central heating station is not used for a long period of time during the cold season, full emptying of the installation is
recommended to prevent damage caused by freezing. It is also recommended to use an anti-freezing agent to avoid
frequent emptying of the installation; when you use the anti-freezing agent, make sure it is compatible with the components of
the station (especially alluminium and stainless steel). Never mix different tpes of nti-freezing gents.
8.1.2 Protection of the st tion in order to keep the w rr nty
Before and during installation, the central heating station must be kept away from impurities: construction dust, sand, copper
dust, fats etc as well as welding splashes, scoria. In any of theses cases, the installation must be washed with clean water mixed
with a highly concentrated cleaning agent.
Genereally, in order to keep the w rr nty it is necess ry to apply any neccesary treatment to prevent the contamination of
water with the following:
Black mud (magnetite - Fe3O4) formed as a result of the continuous electrolyte corrosion occurring in any installation
which is not protected with an inhibitor.

Red mud (rust - Fe2O3) produced during oxidation.
Calcarous deposits produced especially on the hottest areas of the central heating station.
A combin tion of these three f ctors mentioned bove c uses the m jority of the problems occurring with he ting systems.
C ution!
The presence of these subst nces (bl ck mud/ red mud/ c lc rous deposits) me ns th t the st nd rd me sures to
prevent problems of the he ting system were not observed. This is one of the c uses resulting in losing w rr nty!
8.2 G s connecting pipe

Central heating stations C22SPV23MEF function on GN natural gas or on GPL liquified gas. The gas connecting pipe is made of
stainless steel with an interior diameter of 12.4 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.
8.3 Gener l directions for the he ting inst ll tion
C ution! Before connecting the centr l he ting st tion c refully w sh the entire he ting inst ll tion! In this w y, you
elimin te from the pipes v rious debris such s welding spl shes, scori , grummet, putty, dirt or simil r. Otherwise,
these subst nces c n form deposits in the he ting switcher nd c n c use d m ge or m lfunctioning.
C ution!
It is oblig tory to inst ll n impurity filter on the return of the therm l circuit inst ll tion!
When inst lling connecting pipes it is essenti l for these not to be tensed to void cre ting re s of le k ge!
M ximum working pressure llowed is 3b r.
Recommended working pressure is 1.5 b r!
C ution!
It is forbidden to use the centr l he ting st tion without therm l gent or p rtil lly filled – d nger of explosion!
It is forbidden to use the centr l he ting st tion if it is not completely ired!
The equipment is provided with a l 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.
C ution!
Check the pressure inside the exp nsion vessel before commissioning.
Pressure inside the exp nsion vessel must be 0.8÷1b r.
When the thermal installation is designed the hydraulic characteristic of the pump equipping this model of central heating
station will be taken into consideration!
8.4 Gener l directions for the hot w ter circuit

D nger!
It is completely forbidden to use the centr l he ting st tion without the burnt g ses output pipes bec use it end ngeres
people’s life nd he lth of people.
Repl cing is to be performed only by uthorized personnel following pplic ble l ws, using origin l sp re p rts
provided by the m nuf cturer.
8.7 Electric grid connection
The central heating station must be connected to one-phase network of 230V - 50Hz with protection null.
Dispersion withstand of the earthing switch (earthing) must comply with applicable norms (maximum 4 ohm, and the working
null must not have residual current).
Electric powering of the central heating station will be executed from a separate circuit provided with differential protection
fuses of 30 mA.
External connections must comply with applicable norms. Connection to the electric grid of the building must allow the entire
electric insulataion of the central heating station for situations when interventions are required.
Grid connection is done taking into account the symbolism of colours as follows: Brown = phase, Blue = null, Green nd Yellow =
earthing.
The current plug must be accessible so that the user can easily disconnect it.
C ution!
It is not llowed to mount the centr l he ting st tion with defective electric inst ll tion or with no e rthing.
D nger of de th by electric shock with electric cont cts!
8.8 Inst ll tion filling
The following operations are executed to fill the inst ll tion:

9.5 User tr ining
It is obligatory for the specialized personnel commissioning the station to instruct the user about the following aspects:
1. Central heating station switch on/ off procedure in safety conditions by checking the following elements:
- electrical power connection;
- fuel (gas) connection;
- feeding and filling the thermal circuit;
- the station filling tap must be turned off;
- the pressure in the installation by reading the control panel (1.5b r);
- the station taps on the house water circuit must be turned on.
2. The functioning way of the station and possible problems that may occur. Also each key and symbol on the control panel
must be explained.
3. Warn the user that a drop in the water pressure of the system is caused by loss of thermal agent which needs to be
mended before using the station again.
4. Warn the user on the works performed on the air/ gases input/ output systems. Warn the user that ch nging them is strictly
forbidden.
5. It is recommended that the user should have the station verified by an authorized person at least once a year.
6. Warn the user about the the precautions that need to be taken against freezing.
7. Hand the user the user manual of the central heating station.
At the end of training a commissioning statement is signed (table 2), by which the user signs that they are aware of the correct
way of using the central heating station. .
This statement is also signed by the authorized person who commissioned the central heating station.
The authorised person who commissions the station has the right to refuse to sign the station commissioning statement if they
notice defects of the local connecting installations and will not sign the commissioning statement until these defects have been
remedied.
9.6 Quality Conditions and Warranty
