CHIMNEY
For appropriate boiler operation, chimney with a suitable height and diameter has to be installed. Before
connecting the boiler to the chimney, check if its flue is suitable (flue diameter must not be lower than
that of boiler’s flue), if there are other systems connected to the chimney. Chimney must be installed
according to current standards and regulations.
Chimney’s draft must be 12 Pa. If draft is too low, the boiler will operate poorly (build-up of resins,
congestion, smoking) and its service life will be shorter.
NOTE
In order to prevent chimney’s performance deterioration, caused by rain water steam and build-up of
resin, it must be impermeable and isolated.
In case of excessive draft, there is an increase in fuel consumption and in extreme cases there is a
chance of overheating the device.
The technical condition of the chimney to which the boiler is
connected must be assessed by the chimney sweep. To protect the system from gusts of wind, the
chimney must protrude at least one meter above the roof. The room in which the boiler is to be installed
must comply with “Rules for the installation of solid fuel heating stoves in buildings ST 8860237.02:1998”
The chimney must comply with certain regulations in force in the country of operation of the boiler.
The boiler flue must be connected to the steel part of the chimney of the correct size and shape. The
connection must be airtight.
It is recommended to install sealed measuring points in the chimney during installation. We also
recommend that you call a competent person to inspect and clean the chimney at least twice a year
before and after the heating season.

CONNECTION TO THE HYDRAULIC SYSTEM
5.1
Installation in a closed system
According to requirements of this user manual, the boiler is allowed to be used in closed system only
after installing specific safety devices.
The boiler’s power and pellet burner is selected based on the premise heating area, taking into account
the thermal resistance of the room, the amount of hot water prepared, etc., according to the
recommendations of JSC “Stropuva ir ko” specialists.
This work may be performed by an authorized qualified technician.
Manufacturer does not take responsibility for quality, selection and appropriate installation from higher
temperatures than 95 °C and higher pressures than 1,5 bar.
On our manufactured boiler (on the back side, near the flue) there is a ½ inch connection intended for
protection system.
For safety, we recommend a thermal protection device Laddomat 5067 whose heat sensor is mounted
in the water outlet pipe of the boiler.
We recommend calling a competent person for inspection / service of the heating system at least 2
times a year before and after the heating season.
