Boiler Treatment - BaltGaz NEVALUX 7224 User Manual

- The air from the heating system must be removed from time to time (see section10, page19);
-The heating system must be filled with water until the needed pressure is reached (see section10, page19);
-The boiler must be kept clean, for this it is necessary to remove dust from the boiler's front surface regularly, and also
to clean the boiler's coating first with a wet wiper and then with a dry wiper. In case of bigger dirtying you should first
wipe the boiler's coating with a wet wiper, moistened in a neutral detergent, and then with a dry wiper. It is prohibited
to use detergents of heightened effect and containing abrasive particles, gasoline and other organic solvents for
cleaning the coating's surface and plastic details.
CAUTION! Do not change the water in the heating system unless necessary, it will permit to reduce scum
formation in the heat exchanger. Before coming long-term idleness of the boiler in winter time it is necessary to
drain the water from the heating system in order to avoid damaging the pipelines when it freezes.
CAUTION! All boiler treatment operations must be effectuated only after it is disconnected from the network
and has cooled down.
4.3 Operations effectuated at technical service
At technical service the following operations are effectuated:
1) Cleaning of the burner assembly (burner);
2) Cleaning of the heat exchanger from soot and cleaning (washing) the pipes from scum (if necessary);
3) Replacement of grease retainers in the gas and water systems;
4) Checking of the gas and water boiler systems air tightness;
5) Lubrication of flexible joints (if necessary), it is recommended to use thick lubricant greases on
silicone base;
6) Checking of safety devices, they must work without failures;
7) Checking of air pressure in the expansion tank (once in 3 years), the pressure must be 1 bar;
8) The air inlet system and combustion products outlet must be checked for air tightness;
9) Water flow in DHW supply system must be enough for switching the DHW mode on;
10) Checking of the heating system in order to detect stoppage.
CAUTION! Technical service operations connected with disassembling of its gas or water pipelines
must be effectuated only after switching off the boiler completely (taps on gas and water pipelines

at air temperature from −50 ºС to +40 ºС and relative humidity not more than 98%.
-In case of boiler storage for more than 12 month a conservation according to the GOST
9.014−78 standard.
-Inlet and output hoses orifices must be closed by cover plugs.
6. GENERAL REQUIREMENTS
Installation, technical service and initial run of domestic gas facilities must be effectuated in accordance with local
requirements, more specifically:
SNiP II−35−76 «Boiler-plants»;
SP 62.13330.2011 «Gas-distribution systems. Updated edition SNiP 42−01−2002»;
SP 41−108−2004"Door-to-door heating of domestic buildings with gas-fueled heat generators";
SNiP 41-01-2003"Heating, ventilation and conditioning";

PUE "Electrical Installation Regulations".
Also it is necessary to pay CAUTION to the following moments:
-The boiler may be used with any type of heat exchangers (convectional stoves, radiators and convectors), and their
power system may be both double-pipe and single-pipe;
-Children must be kept away from contact with package elements (plastic bags, polystyrene etc.), as they represent a
potential source of danger.
The boiler's initial run and warranty liabilities must be fulfilled by a special service organization.
