to EN 1561
• central sections – quality 150 (previously ČSN 42 2415)
• front and rear sections – quality 200 (previously ČSN 42 2420)
The pressure parts of boiler conform to the strength requirements according to:
EN 303-5 Boilers for central heating– part 5: Solid fuel boilers for central heating, with a manual or
automatic feed, with nominal thermal output max. 300 kW: terminology, requirements, testing
and marking.

The boiler drum is assembled of sections by means of pressed on boiler insertions and secured by means of
anchor bolts. The sections create the combustion and ash-pan space, the water space and convection part.
The inlet and outlet of heating water are situated in the rear part of boiler.
The rear section of boiler in its upper part has a smoke extension piece and heating water flange, in the lower
part there is the return water flange with a sleeve piece for inlet and outlet cocks. To the front section there is
attached the stoking door and ash door with the mounted burner.
The whole boiler drum is insulated by means of a health harmless mineral insulation which reduces the
losses caused by the heat transfer into ambient. The steel shell colour is treated by means of high-quality
komaxit spray.
4.2 Control, regulation and safety elements
Regulator of boiler it serves for automatic control of boiler activities and its elements. It processes the input
data from flue gases and outlet water temperature sensors and according to parameters set by the
manufacturer or user it automatically controls the boiler in the required regimes.
The regulator also allows the manual regime of boiler control which can be advantageously used when
putting the boiler into operation.
Regulator has an automatic electric ignition system and it is developed for the modulation control of fuel
(wooden pellets) supply and modulation control of fan delivery.
The regulator measures the temperature of boiler start and the temperature of combustion products so that
we can regulate the heating output.
The pressure gauge is used to measure water pressure in the heating system and is located in the upper
part of the shell. The check valve for pressure gauge connection is in the top part of the rear boiler section.
Forced-draught fan for the combustion air is mounted directly in the combustion chamber body. The volume
of combustion air is regulated by an air strangler.
The air rosette of stoking door and lower strangler are not used at the Woodpell boiler with an automatic
combustion of wooden pellets and it must be permanently closed.
Cleaning cover of the smoke extension piece is situated in its lower part and it serves for cleaning the
combustion products lines. JS 130 bulb for pro flue gases sensor is mounted in it.
The safety thermostat is positioned in the regulator control box and it serves for heating system prevention
from overheating. It is set by the manufacturer to 95°C temperature it means the temperature higher than the
required temperature possible to be set at the boiler. When the safety thermostat is switched off ( is
shown on the regulator display – see chapt. 8) its deblocking must be carried out manually. The safety
thermostat can only be switched on after the temperature has dropped below the set value. We unscrew the
black cover of the safety thermostat and depress the push button with a suitable object.
In case the safety thermostat is switching off repeatedly the boiler must be put out of operation and the
reason of repeated boiler overheating must be identified.

5.4.6 Filling the heating system with water
Water for filling the boiler and heating system must be clear and colourless, without any suspended
substances, oil and chemically aggressive substances. Its hardness must correspond to ČSN 07 7401 and it
is essential that in case the water hardness is unsuitable the water must be treated. Even the multiple heating
of water with a higher hardness does not prevent the salts from precipitation on the walls of the boiler drum.
The precipitation of 1 mm of calcite in a given place reduces the heat transfer from metal to water by 10 %.
Heating systems with an open expansion tank allow the direct contact between the heating water and
atmosphere. During the heating season the water expanding in the tank absorbs oxygen which increases its
corrosive effects and at the same time a considerable volume of water evaporates. Only water treated
according to ČSN 07 7401 can be used for refilling.
The heating system must be thoroughly flushed in order to wash out all impurities.
During the heating season it is necessary to keep a constant volume of water in the heating system. When
refilling the water in the heating system you must be careful of air sucked in the system, which must not
happen. Water taken or discharged from boiler and heating system must never be used with the exception of
exigencies as are the repairs etc. By water discharging and new water filling the risk of corrosion and scale
formation is increased. If it is necessary to refill water in heating system we only refill the cooled down
boiler in order to prevent the sections from disruption.
After filling the boiler and heating system it is necessary to check the tightness of all joints.
The assembly completion and heating test execution must be recorded in the „Guarantee certificate“.

6. Putting into operation - instructions for contractual service
organization
The boiler can only be put into operation by a contractual service organization authorized to carry out
this activity.
6.1 Inspections before start-up
Before putting the boiler into operation it I necessary to check:
a) Filling the heating system with water (check of the manometer).
b) Tightness of heating system.
c) Connection to the chimney – it must be approved by a chimney-sweepers’ company.
d) Connection to the electricity network - it must be approved by an authorized company.
When connecting the sockets the grounding pin must be upward and the phase conductor is connected
to the left female connector in front view. The same applies to the double receptacles.
6.2 Boiler putting into operation
1. Fire the boiler (see chap. 7.). When firing up the protective spraying of boiler section is baked and this
process is accompanied by a slight smell. Mind the boiler room ventilation.
2. Bring boiler to the necessary service temperature. The recommended heating water temperature is
between 60 and 80 °C.
3. Recheck visually the boiler tightness.
4. Carry out the heating test according to relevant standards (see the Guarantee certificate).
5. Make the user acquainted with boiler attendance (see chap. 7).
6. Make a registration in the Guarantee certificate.
7. Boiler attendance by user
7.1 Regulator attendance by user
Puma PID 46 controller is characterized by continuous boiler control. Mutually independently it evaluates the
increase in water temperature and flue gas temperature. It is equipped with 3 temperature sensors and
5 controlling outputs:
• fan
• feeder
• pump CH
• pump HWS
• lighter
The controller enables collaboration with room
thermostat.
The controller will turn on the CH pump at the
moment of switching the thermostat, so the room
is heated to the desired temperature. The pump
runs in the mode: 18 minutes working, 2 minutes
pause.If the thermostat does not require the
heating, the CH pump operates in the mode: 2
minutes working, 18 minutes pause. This setting is
because of the minimum supply of hot water into
system. Thus the room is protected against
freezing when the room thermostat has a flat
battery.
For room thermostat connection and activation
please contact the service organization.
After the room thermostat activation the display
shows an icon signalling the room thermostat.
The controller ensures the rpm control of the pump. The pump must be set in position II.
In the event that to the system there are connected the pumps which are equipped with automatic rpm control
it is necessary to switch off the function of pump rpm control in the controller.
