Technical staff manual
(metallopolymeric pipes). It is acceptable to use multi-layered metallopolymeric pipes for inner gas pipelines
at natural gas provision to one-flat domestic buildings not higher than 3 floors in condition if they are
confirmed as acceptable for construction use. It is acceptable to connect the boiler to the gas pipeline by a
flexible tubing (hose), resistant to transported gas at set pressure and temperature. The inner diameter of pipes
and hoses must be not less than 20 mm.
In accordance with p. 5.5 SP 41−108−2004 the flexible connections shall be not longer than 1,5 m. The
hoses must be installed in accordance with the instructions of their manufacturer.
- Remove cover plugs from connection pipes;
-Install the gas filter and stop valve on the gas pipeline by the inlet into the boiler;
-The gas valve must me easily accessible;
-Connect the boiler to the gas pipeline. Check that there are no gas leakages. Airtightness control is
effectuated by means of a soap solution bubble test on the joints or by other safe methods. Appearance of
bubbles means that there is a gas leakage. The gas leakage is unacceptable.
8.4. Connecting the boiler to the liquefied gas cylinder
-Before connecting the boiler to the liquefied gas cylinder make sure that your boiler is set up for
operation with this type of gas. Otherwise it is necessary to effectuate the boiler’s rendering to liquefied
gas in accordance with section 12 (page 26).
-The balloon with liquefied gas must necessarily be equipped with a reduction unit with vapor phase
stabilization pressure of 2,9kPa and vapor phase capacity not less than 1 m
3
/hour.
CAUTION! Using reduction units with stabilization pressure different from 2,9 kPa IS
PROHIBITED.
-The hose length for connecting the boiler must be not more than 1,5 m., the inner diameter- not less than
20 mm. The gas supply hose must be resistant to the supplied gas at set pressure and temperature. The
hoses should be installed in accordance with the instructions of their manufacturer.
-In front of the boiler’s inlet a stop gas valve must be installed, which must be easily accessible.
-After finishing the installation it is necessary to check the joints and the whole length of the connection hose
in order to detect a gas leakage (see p. 8.3)
In order to avoid accidents it is PROHIBITED:
1)To keep gas balloons and lay hoses under direct sunlight, next to heat sources (heating stove, oven,
heating radiators, other heating appliances);
2) To heat the balloons by means of flame or heating appliances;
3) To use damaged gas balloons.
It is recommended to keep gas balloons in a special metal cabinet in order to limit access of children and
unauthorized persons to them. Placing gas-cylinder installations inside the building is unacceptable.
8.5 Connecting the boiler to the power line
The boiler corresponds to the I class electric shock hazard protection. It is necessary to make sure that there is an
AC outlet of alternate current monophase network with rated voltage 220 V. 50 Hz frequency and with an earth
contact.
In order to provide safety when power supply is beyond the range of 190-250 V the electronic board renders the
boiler to standby mode (see p. 3.3.4, page 11).
The boilers earth must be effectuated following all earth requirements in accordance with GOST 27570.0−87
standard. The earth conductor is connected to the earth screw on the boiler’s bottom panel (marked with the
symbol Θ )by one end, and by the other end to the earth loop of the premise where the boiler is installed. It is
prohibited to use heat carrier, water and gas pipelines and also the heating radiators for earth. The scheme of the
boiler’s electric connections is represented in Annex III (page 66).
Note.
It is recommended to effect the boiler’s connection to the power line through a Constant voltage regulator
in order to provide stable and failure-free operation and also to prevent the boiler’s breakdown because of power
line surges.
CAUTION! In case of power cable damage, in order to avoid danger, its replacement must be effectuated
by a specialized service organization.
CAUTION! The manufacturer bears no responsibilities for failures caused by non-compliance with the
above-listed requirements. All activities, not complying with the activities listed in this Manual, may not
only cause the boiler’s breakdown, but also create a life hazard.
9.
SMOKE EXHAUSTER INSTALLATION
It is strictly prohibited to put the boiler into operation in case if the smoke exhausting pipe is not
installed, in order to avoid combustion products poisoning.
The boiler has an air inlet duct for combustion and a combustion products outlet duct, what permits not to use the
air from the premise. Using different component parts, you may connect a coaxial pipe (see p. 9.1 page 17) or two
separate pipes (see p. 9.2 page 18) to the upper part of the wall-hung boiler with further output of them from the
premise.
The pipes for combustion products removal must comply with the following requirements:
-The pipe must be made from non-flammable material, resistant to mechanical deformations, not subject to
corrosion, and fully airtight. It also must be protected from overheating, from inflammation and freezing;
- The joints of the smoke exhauster pipe must be made of thermo-resistant material not subject to corrosion;
-The smoke exhauster pipe must be installed in a place available for service so that, in case of the pipe’s damage,
there would be no hindrance for smoke leakage elimination.
After installing the smoke exhauster, it if necessary to effectuate the following.
-To make sure that there are no narrowings in the smoke exhauster, and also that outlet pipeworks of other boilers
are not connected to it. It is acceptable only in case if the smoke exhauster is designed for several users and is
produced in accordance with local requirements;
-If the boiler must be connected to an existing smoke exhauster, it is necessary to make sure that the latter is clean,
as slag separation from the smoke exhauster’s walls while the boiler is in operation might encumber the free outlet
of exhausted gases.
In order to purchase the necessary parts and details of the smoke exhauster you should contact the trading
organization, effectuating realization of accessories for the boilers “BaltGaz NEVALUX” in your region.
CAUTION! It is prohibited to use ventilation channels for combustion products removal.
9.1.Installation of coaxial smoke exhauster
Connecting the coaxial pipe to the boiler is effectuated by means of a connection set KHG 714101410 (not
included into the supply package), which includes a coaxial branch pipe 90 °, a joint sleeve for connecting to the
boiler’s outlet and gasket (see scheme 6). If necessary the connection set KHG 714101610 can be used (not
included into the supply package), with a branch pipe 45 °.
