- 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.
8.1.2 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!
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).
8.2 Gas connectiong 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!
Is is obligatory to istall a pressure regulator on the fuel input circuit, adjusted at 20
mbar.
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!!
