Installation
Danger!
Danger of death by poisoning and explosion because of breeches in the gas pipes and connections in case of
incorrect installation! Installation and commissioning can be done only by a company authorized and agreed by
KÖBER SRL-Vaduri Branch! This company will assume responsibility for the correct installation and commissioning.
5.1
Conditions for the installation of the central heating BOILER
5.1.1
Installation indication
The central heating BOILER 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 BOILER 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: 7,5<pH<9,5
It is recommended to check the water and thermal agent pH frequently and if the value does not fall within the limits provided
by the manufacturer, it will be treated again.
- 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 BOILER startup cycles with the fuel tap off in order to air the installation. The BOILER is
also provided with a manual ventilator, installed on the heat switch.
- If the central heating BOILER 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.
5.1.2
Protection of the BOILER in order to keep the warranty
Before and during installation, the central heating BOILER 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 warranty it is necessary
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 BOILER.
A combination of these three factors mentioned above causes the majority of the problems occurring with heating systems.
Caution!
The presence of these substances (black mud/ red mud/ calcarous deposits) means that the standard measures to
prevent problems of the heating system were not observed.
This is one of the causes resulting in losing warranty!
5.2
Gas connecting pipe
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 limite may resul in damage.
Work pressure with G20 natural gas functioning must be 20 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 BOILERs
C13SPV36MEF, C14SPV25MEF
function on
GN
natural 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 BOILER. The fuel input must be done according to applicable legal stipulations.
5.3
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 11.3 for pump characteristic.
