3.1. Requirements of boiler installation
3.1.1. The regulations on the water installation, gas and the
flue gas system
Water, gas and flue gas systems must meet local regulations as well
as use of the gas, ventilation and flue gas installation.
The use of gas appliances, flues and ventilation by the user should be
consistent with local requirements on technical conditions of tenant
buildings use.
Before installing the boiler the consent from the District Department
of Gas, Chimney sweep company and Building administration must
be obtained.
3.1.2. Regulations related to the room
Requirements for premises where gas appliances are installed shall
be in accordance with local regulations. The room where appliance is
to be installed should ensure the air supply and venting system
necessary for gas combustion in accordance with local regulations.
The room should be protected against freezing, free from dust and
aggressive gases. It is forbidden to install the device in a laundry
rooms, drying rooms and in varnish, cleaners, solvents and sprays
storages.
The boiler should be installed in a technical room.
Gas appliances supplied with liquefied gas must not be
installed in room with a floor below ground level.
3.1.3. Requirements for electrical installation
The boiler has been designed for operation with single-phase
alternating current with rated voltage of 230 V / 50 Hz. Max power
consumption
–
please see rating plate or technical data table. The
main socket from which boiler is powered must meet the local
requirements.
The boiler has been designed as a Class I device and must be
connected to an electrical outlet with ground terminal in accordance
with PN IEC 60364-4-41. The boiler has a degree of electrical
protection provided by the housing
–
X4D.
It should be checked by a suitably qualified person whether the
electrical installation is suitable for the maximum power
consumption of the device, making sure in particular that the cross-
section of the cables is suitable for the power consumed by the
device.
If the boiler is permanently connected to the power source, it should
be execute by junction box. The junction box must be equipped with
protection degree appropriate for the defined assembly zone. If the
boiler is connected through the junction box, electric system must be
equipped with measures which can disconnecting the boiler from the
power source.
In order to connect the boiler to the junction box, it is recommended
to:
- cut the power cord to a suitable length for connection to the box
- pull off cable insulation
- put the cable-end sleeve with the appropriate diameter
This prepared cables connect according to Fig 3.1.3.1.

If you need to replace the supply wire, use a minimum cord of 3 x
0.75 mm
2
. The boiler supply wire is screwed to the connection list on
the control panel to terminals marked with ~ 230 V (see section
3.9.1).
The power cord of the device cannot be replaced by the user. To
replace it please contact with qualified personnel.
The use of any device powered by electricity requires to compliance
with the basic principles, i.e.:
•
do not touch the device with wet or damp body parts and / or
being barefoot;
•
do not jerk the electrical cables;
•
do not expose the device to weather conditions (rain, sun, etc.);
•
do not allow children or persons with no experience or knowledge
to operate the device.
3.2. Preliminary check activities
Before proceeding with the boiler installation:
•
check whether the boiler is factory designed for the type of gas
supplied from the gas system. The type of gas which the boiler is
adjusted to is specified on the rating plate on the cover of the
boiler;
•
check whether the water system and radiators have been rinsed
with water in order to remove rust, fillings scale, sand and other
dusts that could disturb the proper operation of the boiler (for
example increase the water flow resistance in central heating
system) or to pollute the heat exchanger,
•
whether the mains voltage has a value of 230V and the phase wire
(L) is in the right place; and that the socket has an efficient safety
contact (complies with IEC-60 364-6-61: 2000)
•
whether the flue-gas air installation is tightly connected and not
obstructed.
3.3. Boiler installation
The device may only be installed on a vertical wall
sufficiently strong to maintain its weight. For mounting,
use a fastening system adapted to the wall structure.
- The most important mounting dimensions are shown on Fig. 3.3.1
- In order to ensure free access during inspections and maintenance,
it is advisable to maintain the minimum distances according to
Fig. 3.3.3.

The boiler has two mounting possibilities presented on Fig. 3.3.2
- Using the attached hanger
- Hanging on mounting hooks (min. size of wall plug is
ø
16x100)
Mounting method:
1. In order to facilitate assembly, use the mounting template
attached to the boiler.
2. Attach the template to the wall and mark all the space needed for
installation.
3. Remove the template and drill the necessary mounting holes.
4. Screw the hanger (attached to the boiler) to the wall or mount the
hooks.
