7.8 Installation of the appliance's power elements
Power elements of the typical size D are installed into the battery section 13 (see. Scheme 10, Scheme 11,
Scheme 12) in accordance with polarity indicated on the inner side of the cover of the section. It is
recommended to install the alkaline power elements of the LR20 type, with higher energy output ratio
providing more durable operation of the appliance.
7.9
Checking the appliance
After installing the appliance and checking it on air-tightness, you must check: the operation of the
ignition and main burner (p. 4.1.2, 4.1.3, page 9), automatic safety devices operation (п. 8.2.6, page 20), and
the hot water's temperature and consumption. Switching the appliance on and off and regulation of its water
temperature must be effectuated in accordance with section 3 (page 7).
Note: After keeping the appliance in a premise with sub-zero temperature, it is recommended to perform
its first launching not earlier than in 1,5 h after it was brought to a warm premise.
If necessary (in case of insufficient water heating) the appliance's inlet gas pressure should be checked.
In order to measure gas pressure, having previously closed the gas stop valve by the appliance's inlet, it is
necessary to connect a manometer to the fitting 17 (Scheme 10, Scheme 11);
Gas pressure measurement must be effectuated on the operating appliance and at maximum gas
consumption. Gas pressure must comply with the value indicated in the Acceptance certificate.
7.10Rendering the appliance to another type and pressure of gas
7.10.1 Rendering the appliance to another type of pressure or gas must be done by a specialized service
organization. For rendering it is necessary to use only a branded set of details.
Before rendering it is necessary to switch the appliance off and close the gas stop valve.
7.10.2 In order to render the appliance to another type of gas or pressure it is necessary to replace the nozzles
of the main burner's manifold and the nozzle of the
ignition burner for the nozzles with an orifice diameter in
accordance with table 1 for the type and pressure of gas
the appliance will operate on.
For operating on natural gas a jumper in the electronic
control block must be installed, it is shown with the arrow on
Scheme 13.
When rendering the appliance from natural gas to liquefied
gas it is necessary to remove the jumper from the electronic
control block (it is acceptable to install the jumper on one of the
contacts).
After rendering it is necessary to check the joints' air-tightness.
The type and pressure of gas the appliance has been rendered on, must be indicate in the
Acceptance certificate (indicating the organization that effectuated the rendering and the date of
effectuation) and in the table on the appliance
.
