3. Installation instructions
3.1 Boiler construction
The sectional boiler drum made of grey cast iron according to EN 1561, quality 150 is the main part of the
boiler.
Pressure parts of boiler correspond to strength requirements according to EN 303 - 5 – Heating boilers –
Part 5: Heating boilers for solid fuels with manual or automatic stoking and nominal heat output of up to
300 kW – Terminology, requirements, testing and marking.
The boiler drum is made of sections by means of pressed boiler inserts (nipples) Φ56 mm and rubber o-
rings and secured by anchor bolts. The sections create combustion space, ash pan and water spaces and
also the convection part. The feed shaft consists of feed hopper, which is made of sheet metal intended for
combustion processes. The upper part of the feed hopper is water-cooled. The heating water inlet and outlet
are situated at the rear part of the boiler.
At the rear section of the boiler there is mounted the smoke adaptor with air exchanger and exhaust
ventilator. The return water connection is situated in the upper part of boiler drum. The heating water
connection is situated in the upper part of the feed hopper. Water inlet and outlet can be connected by
means of threaded pipes. The stoking door is mounted to the feed hopper and the ash pan door to the front
boiler section. The ash pan and stoking door are made with the possibility of left-right opening (see Fig.
No. 5).The whole boiler drum is insulated by using the harmless mineral insulation, which reduces the losses
caused by the heat transfer to the ambient. The boiler shell is coated with high-quality comaxit spray.

The choice of the right size of boiler
The choice of the right size of boiler i.e. its heat output is very important condition for economic operation
and a correct function of the boiler. The boiler must be chosen so that its rated thermal output corresponds to
the heat losses of the building. The rated output is calculated according to valid standards for outside
temperatures –12 °C, -15 °C and –18 °C. The choice of boiler with too high rated output (oversizing) results
in increased tarring and retting of the boiler. That’s why it is not suitable to use boilers with the output higher
than the heat losses of the building
This does not apply in case the boiler is connected in the system with a storage tank.
Chimney draught
The chimney with its proper draught is a fundamental prerequisite for a good function of boiler. It influences
both boiler output and its efficiency. The boiler may be connected to chimney vent which has a sufficient
draught (see chapter 2.3) and the revision must be carried out by an authorized organization.
