11)
Checking of the heating system in order to detect contamination.
CAUTION! Technical service operations connected with disassembling of its gas or hydraulic pipelines
must be effectuated only after switching off the boiler completely (the taps on heat carrier , water and gas
pipelines by the inlet into the boiler must be closed, the boiler must be disconnected from the power line).

STORAGE PRECAUTIONS
-The boiler is made in climatic category UHL4.2 under GOST 15150-69 standard.
-The boiler must be stored and transported in the package only in the position indicated on the handling
symbols.
- The boiler must be stored in a closed premise that guarantees protection from atmospheric and other harmful
impacts 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 must be effectuated.
-Inlet and output hoses orifices must be closed by cover plugs.

GENERAL REQUIREMENTS
Installation, technical service and initial run of gas appliances for domestic use 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”;
”Regulation of fire safety in Russian Federation” (PPB 01−03);
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.

OPERATIONS BEFORE INSTALLATION
CAUTION! Boiler installation, putting the boiler into operation and technical service can be
effectuated only by a specialized service organization. Boiler installation must be effectuated
according to the project which complies with the requirements of Federal and local normative acts,
regulating gas appliances installation.
The boiler is designed for heating water to the temperature lower than the boiling point at atmospheric
pressure.
The boiler should be connected to the heating system, and also to the water supply network in order to
receive domestic hot water for housekeeping needs (hereinafter referred to as DHW), and after that to the
gas pipeline. Heating and water supply systems must be compatible with the boiler’s exploitation
characteristics and power.
The boiler’s technical characteristics are represented in p.2.2 (page 5).
Before putting the boiler into operation it is necessary to effectuate the following:
-To check the compliance of the type of gas and pressure indicated in the sections 20 and 21 (page 48) and
in the table o the boiler with the used type of gas and gas pressure in the place of the boiler’s installation.
In case of non-compliance it is necessary to render the boiler to the used type of gas and pressure in
accordance with section 12 (page 26);
-To make sure that the installation was correct and the smoke exhauster is airtight;
-In order to provide correct boiler operation ant to keep the warranty it is necessary to follow the
requirements of this manual.
7.1 DHW Line
For normal boiler operation it is necessary to install a water filter by the inlet into the boiler on the DHW
line.
If water hardness exceeds 200 mg of calcium carbonate per 1 liter water, it is necessary to install a
polyphosphates dose meter or another water softening device.
7.2. Heating system
The boiler is connected to the heating system and DHW system, in accordance with its characteristics and
heating power.
Minimal heat output of the heating system must be more than 8,9 kW. Otherwise, the boiler will
operate unstably, what would lead to reduction of its service life.
It is recommended to use water as a heat carrier in the heating system. It is acceptable to use
Propylenglycolum as a heat carrier.
Presence of rust, dirt and other deposits in the heating system leads to the boiler’s operation disturbance
and performance degradation (for example overheating, noise in the heat exchanger, heating effect
reduction). In connection to this, the heating system must be washed before the boiler’s installation. For
this acid and alkaline-based detergents or detergents, corroding metal, plastic and rubber parts of the
boiler, cannot be used.
It is recommended to use SENTINEL X400 и SENTINEL X100. The purchased heating system cleaning
detergent must be used in accordance with the instruction attached to it.
7.2.1 Water quality requirements
The quality water used in the heating system must comply with the following parameters:
-
РН value
6-8
-
General hardness
not more than 4 mg-eq/l
-
Iron content
not more than 0,3 mg/l
If the incoming water’s hardness exceeds 4 mg-eq/l, it is necessary to install by the water’s inlet into the
boiler a polyphosphates dose meter, which processes the water coming into the boiler, protecting the heat
exchanging equipment of the boiler from hardness deposition. The polyphosphates dose meter is not included
