7.3. Connecting the appliance to the water supply system
7.3.1. In order to increase the appliance’s working lifespan and improve its exploitation characteristics is
recommended to install a water filter by the appliance’s inlet (see scheme 6)
7.3.2. In order to facilitate further technical service it is necessary to install by the appliance’s inlet a stop valve on
the cold water supply pipeline. The stop valve must be easily accessible.
7.3.3. Connecting appliance to the water supply system should be effectuated with metallic tubes or flexible hoses
with inner diameter not less than 13 mm. The length of the flexible hose for water inlet or output should be not more
than 2,5 m. Rules of flexible hoses installation are represented in the p. 7.6, page 13.
7.3.4. Cold water connection must be effectuated to the fitting of cold water supply 5, and hot water connection - to
the fitting of hot water outlet 7 (see scheme 1, 2), having previously removed protective gags from the fittings.
7.3.5. Connection of pipes of hot and cold water should not be accompanied by mutual interference of pipes and
parts of the appliance in order to avoid displacement or breakage of separate details and parts of the appliance and
disturbance of water system’s air-tightness.
7.3.6. Before connecting the appliance to the water supply network it is necessary to open the cold water supply for
some time to clean the pipe of water supply to the appliance and prevent unwanted entering of the contamination and
sediments at its first starting up.
7.3.7. After connecting the pipelines to the appliance it is necessary to test joints on air-tightness. Air-tightness
check is done as follows:
a)
Open the hot water tap;
b)
Open the cold water stop valve by the appliance’s inlet;
c)
After
filling the appliance’s duct with water, close the hot water tap and examine the joints.
Leakage in the joints is unacceptable. It is also recommended to examine the joints of the appliance’s water duct,
as their air-tightness disturbance is possible in c
ase of the appliance’s transportation and storage conditions
violation. Tighten the joints if necessary.
7.4
Connecting the appliance to the gas system
7.4.1. In order to increase the appliance’s working lifespan and improve its exploitation characteristics is recommended
to install a gas filter by the appliance’s inlet (see scheme 6, page 11)
7.4.2 In order to ensure stable operation of the appliance it is necessary to effectuate the gas line connection with metal
pipes or flexible hose with an internal diameter not less than 13 mm. The flexible hose for supplying gas, in accordance
with the SNiP 42-01-2002 requirements must be resistant to the supplied gas at set temperature and pressure. Flexible
hose length should not be more than 2.5 meter. Flexible hoses installation rules are given in p. 7.6. Pipes or a flexible
hose should be connected to the fitting 6 (see scheme. 1,2, page 6) after removing the protective gag from it.
7.4.3.
Installation of the gas pipelines’ dismountable joints should be kept to a minimum.
7.4.4. When connecting a gas line to the appliance
, there should be obligatory a stop valve installed by the appliance’s
inlet. The stop valve must be easily accessible.
7.4.5. Connecting the gas pipe must not be accompanied by mutual interference of pipes and parts of the appliance in
order to avoid displacement or breakage of individual details and parts of the appliance and a violation of the gas line
air-tightness.
7.4.6. After connecting the appliance to the gas line, the joints of connection of the appliance with the pipes should be
tested on air-tightness. Air-tightness check in the joints of gas supply is made on non-operating appliance and when the
appliance’s inlet stop valve is open. Gas leakage is not allowed.
Checking the air-tightness of the gas joints is effectuated by means of soap solution bubble test of the connection
points (or other safe methods without using open flame). Appearance of bubbles indicates gas leakage.

7.5
Connecting the appliance to the LPG cylinder
7.5.1. Before connecting the appliance to LPG cylinder make sure that your appliance is adjusted to work with this
type of gas. Otherwise it is necessary to render it (see p. 7.10, page 15).
7.5.2. The LPG cylinder must necessarily be equipped with a reduction unit with vapor phase stabilization pressure
300 mm w.g., and the vapor phase output at least 1 m3/h.
ATTENTION!
Usage of reduction units with stabilization pressure different from 2.9 kPa is PROHIBITED.
7.5.3. The length of a flexible hose for connecting the appliance should be not more than 2.5 m and the inner
diameter not less than 12 mm. A flexible hose for gas supply should be resistant to the supplied gas at set temperature
and pressure. Rules of flexible hoses installation are given in p. 7.6.
7.5.4 The flexible hose must be connected to the fitting 6 (see scheme 1, 2 page 6), after removing the protective
gag from it.
7.5.5
. A gas stop valve should be installed by the appliance’s inlet. The stop valve must be easily accessible. It is
also recommended to
install a gas filter by the appliance’s inlet
7.5.6. After the mounting termination, it is necessary to check the joints and the entire length of the connecting hose for
air-tightness (see p.7.4.6).
7.5.7. In order to avoid accidents it is
PROHIBITED TO
:
- store gas cylinders and lay hoses under direct sunlight, next to heat sources (ovens, stoves, radiators and other
heating appliances);
- heat the gas cylinders with flame or heating appliances;
- use damaged gas cylinders.
