ATTENTION!
Do not let little children play with the packaging material, as it may be dangerous for them. After
installing the appliance the package may be utilized.
7.2.2. The appliance is hanged by mounting holes (on the rear wall) on two hangers installed into the wall (hangers and
wall dowels are included into the supply package). The position and size of the mounting holes, and also overall and
connection dimensions for connecting water and gas pipelines and combustion products outlet are shown on scheme 1, 4.
7.3. Connecting the appliance to the DHW system
7.3.1. In order to increase the appliance
’s working lifespan and improve its exploitation characteristics it is
recommended to install the water filter before the appliance (see scheme 9).
7.3.2. In order to facilitate further technical service it is necessary to install a stop valve on the cold water supply
pipeline by the inlet into the appliance (scheme 9). The stop valve must be easily accessible.
7.3.3. The connection of the appliance to the DHW system must be effectuated with metal pipes or flexible hoses with
inner diameter not less than 13 mm. The water inlet and outlet flexible hose length must be not less than 2,5 m. The rules of
flexible hoses installation are stated in p. 7.6.
7.3.4. The cold water supply connection must be effectuated to the cold water inlet tap 6, and hot water
– to the hot water
outlet tap 8 (see scheme 1, 2), previously taking off the protective cover plugs from the taps.
7.3.5. The connection of the cold and hot water pipelines must not be accompanied with mutual overpull of the pipes
and parts of the appliance in order to avoid displacement or breakdown of some parts of the appliance and break of the
water system
’s airtightness.
7.3.6. Before connecting the water heater to the DHW system it is necessary to open the cold water supply for some
time, in order to clean the pipe of water supply to the appliance and to prevent undesirable dirt and deposits inserton into the
appliance at its initial run.
7.3.7. After connecting the pipelines to the appliance it is necessary to check the joints airtightness. Airtightness check is
effectuated in the following order:
а) open the hot water tap;
b) open the cold water stop valve by the inlet into the appliance;
c) after filling the appliance
’s duct with water close the hot water tap and examine the joints.
Leakage at the joints is unacceptable. It is recommended also to examine the appliance
’s water duct joints, as break of
their airtightness is possible in case of violation of the appliance’s transportation and storage conditions. If necessary the
joints must be tightened up.
Maximum water pressure for which the appliance is designed (also in case of water heat expansion) - 1000 kPa.
7.4. Connecting the appliance to the gas system
7.4.1.In order to provide the appliance
’s stable operation it is necessary to effect the gas pipeline connection with metal
pipes or flexible hoses with inner diameter not less than 13 m. The flexible hose for gas inlet, in accordance with the
requirements of SP 62.13330.2011, must be resistant to the inlet gas at set pressure and temperature. The flexible hose
length must be not more than 2,5 m. The flexible hoses installation rules are stated in p. 7.6. The pipes or the flexible hose
are connected to the tap 7 (see scheme 1, 2) after removing the protective cover plug from it.
7.4.2. At gas pipelines installation the number of dismountable joints must be reduced to a minimum.
7.4.3. At gas pipelines connection to the appliance by the inlet into the appliance a stop valve must be necessarily
installed. The stop valve must be easily accessible.
7.4.4. The connection of the gas pipe must not be accompanied with mutual overpull of the pipes and parts of the
appliance in order to avoid displacement or breakdown of some parts of the appliance and break of the gas pipeline
’s
airtightness.
7.4.5. After connecting the appliance to the gas pipeline the joints of the appliance and pipeline must be checked for
airtightness. Checking the gas supply joints
’ airtightness is effectuated when the appliance is not in operation and the stop
valve by the inlet into the appliance is in open position. Gas leakage is unacceptable.
Checking of the joints
’ airtightness is effectuated by means of a soap solution bubble test (or by other safe methods with
no use of open fire sources). Bubble appearance means gas leakage.
7.5. Connecting the appliance to the balloon with liquefied gas
7.5.1. Before connecting the appliance to the the balloon with liquefied gas make sure that your appliance is set up for
operation on this type of gas. Otherwise the appliance must be reset for it.
(see p. 7.10).
7.5.2. The balloon with liquefied gas must be necessarily equipped with a reduction unit with vapor phase stabilization
pressure of 2,9 kPa and and vapor phase capacity not less than 1 m
3
/h.
ATTENTION!
Using reduction units with stabilization pressure different from 2,9 kPa IS PROHIBITED
.
7.5.3. The flexible hose length for connecting the appliance must be not more than 2,5 m., the inner diameter- not
less than 12 mm. The gas supply flexible hose must be resistant to the supplied gas at set pressure and temperature.
Rules of flexible hoses installation are stated in p. 7.6.
7.5.4. By the inlet into the inlet into the appliance a stop valve must be installed. The stop valve must be easily
accessible.
7.5.5. After finishing the appliance
’s mounting it is necessary to check the joints and the whole length of the connection
hose in order to detect gas leakage (see p. 7.4.5).
7.5.6.
In order to avoid accidents it is PROHIBITED
:
To keep gas balloons and lay hoses under direct sunlight, close to heat sources (heating stove, oven, heating
radiators, other heating appliances);
To heat the balloons by means of flame or heating appliances;
To use damaged gas balloons.
