TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
Q – boiler output in kW
- Remove the packaging without polluting the environment
- Observe building supervision instructions, in particular the
existing Ordinance on combustion devices and storage of
combustion materials, on building requirements applicable
to installation sites and on ventilation;
- The boiler must be placed on a foundation whose surface
area is larger than the base of the heating boiler according
to diagram 1;
- The boiler must be placed in a position which allows for the
easiest possible cleaning and servicing;
- Installation must be carried out according to installation
diagram 1 which shows the boiler housing;
- No objects made of flammable materials or liquids may be
placed on/near the boiler;
7. SETUP OF THE HEATING BOILER
7.1. Connecting the boiler to a chimney
Boiler-to-chimney connection must always comply with the
existing standards and rules. The chimney must provide
sufficient draught for evacuation of the smoke under any
conditions.
The proper functioning of the chimney requires adequate
sizing of the chimney itself since the draught it produces
affects combustion, boiler’s output and life span.
The draught created by the chimney is in functional relation
to its cross-section, height and the roughness of its interior
walls. No other appliance may be connected to the chimney
serving the boiler. Chimney diameter must not be smaller
than the flue outlet of the boiler. Flue outlet must be
connected to the chimney opening. In terms of mechanical
properties, the flue outlet must be sturdy and properly sealed
(to avoid gas leak) and allow for easy access for cleaning on
the inside. The inner section of the flue outlet must not be
greater than the effective section of the chimney and must
not narrow. Avoid using elbow joints.

Data in the tables are for indicative purposes.
Draught depends on the diameter, height, uneven
sections along the chimney surface and differences
in temperature of combustion products and
outside air. We recommend that you use chimney
fitted with flue terminal. Heating specialist must
calculate the precise sizing of the chimney.
The chimney cleaning opening has to be in its lowest part.
The chimney’s wall has to be threeplied where the medium
layer is from mineral wool. The thickness of the insulation is
not less than 30 mm when the chimney is setting up inside
the house and the thickness is 50 mm, when the setting up
is outside.
The inner diameter of the chimney depends on its real height
and the power capacity of the boiler (see diagram 6).
7.2. Connecting the boiler to the mains power supply
+
Caution! ELECTRIC SHOCK HAZARD!
-
Before opening the unit: switch off the voltage and
secure the unit against accidental restart.
- Observe installation instructions.
 All connection works must only be carried out by
qualified electricians.
 Improper cable connections may damage the
regulator!
 The device may be damaged if struck by a lightning.
Make sure it is unplugged during the storms.
 It is mandatory to assure a backup power generator
of corresponding rated power! (see 12.2)

The boiler must be connected to a 220V / 50Hz mains using
power cord.
Create tight connection with the electrical mains which
complies with the local regulations (see diagram 8, 9).
7.3. Connecting the safety heat exchanger
 Such connection must be performed by a technician
/ service shop authorized for such operations.
The Dual Chamber boiler DC - A is equipped with safety heat
exchanger (cooling circuit). It connects to the water system
through a thermostatic valve. In case of overheating, the
thermostatic valve feeds in cold water from the water mains
which passes through the heat exchanger and absorbs the
heat in the boiler. The water is then discharged into the
sewage system. This arrangement ensures safe evacuation
of the excess heat without the need for additional energy.
This guarantees that the water in the boiler will not exceed
the maximum safe level of 95°C .
The minimum operating pressure of the cooling water in the
safety heat exchanger must be within the range 2 ÷ 10 bar .
A flow rate of at least 12 l/min is required. Connect the
safety heat exchanger according to the hydraulic diagram
using thermostatic valve. Install a filter on the inlet before
the thermostatic valve.
