Technopel Compact Pellet Boiler Installation and User’s Manual
INTRODUCTION
Thank you so much for choosing the Ünmak brand Technopel Compact Pellet Boiler. Please carefully
read the manual before installation for comfortable, long-lasting, high efficiency, and economic use.
Do not touch any part of the boiler except for operation, adjustment, and
maintenance purposes that specified in the manual.
Installation, maintenance, and service of the boiler must be done by a
professional authorized technical service.
This manual and regulations should be considered for the installation of the
boiler, the selection of the correct place for the installation, the plumbing
system installation, and the design of the chimney.
ÜNMAK Pellet boilers are high-efficiency, steel-welded hot water boilers and have been designed to
burn only wood pellets. These boilers are only used for heating systems, they are not suitable for
direct domestic water heating. However, it can supply domestic hot water with a boiler or heat
exchanger. The energy requirement for domestic water will be supplied from boiler energy.
ÜNMAK Pellet boilers transform the energy of the fuel inside the hopper from chemical to heat
energy and supply to the liquid of central heating system.
The powdered fuels will pass through the combustion chamber with the fume extractor. Efficient
combustion is not seen in this type of fuel. The powdered fuel can cause the auger to clog due to
more moisture in the fuel. Depending on the heating values of the fuels, the heat given to the water
from the boiler may exceed the declared values.
ATTENTION
Please read this installation and user manual carefully. Please keep the warranty
certificate until the end of the product life.

There should be no defective or suspicious electrical lines in the boiler room.
The 230 V electrical connection of the control panel should be connected to the mains
via an automatic fuse (W automat).
SAFETY PRECAUTIONS
The boiler must be connected to a chimney in accordance with the features specified in the manual
and the relevant regulations. Chimney should provide required stack draught values of the boiler.
The boiler should not operate without a flue connection and without an adequate stack draught.
Faulty electrical cables in the place of the installed boiler must be removed.
In the case of boiler replacement in boiler rooms, the former boiler must be disassembled or
chimney connection must be cut off and the cut point must be
isolated. It should not connect more than one boiler to the
same chimney.
Chimney of Technopel Pellet Boilers is individually used as
well. The chimney and fresh air suction line can be taken out
from the back of the boiler room. The flue cap must put to the
outlet section of the chimney. It can be made of metal or heat-resistant material.
Please do not overload the boiler, do not open the boiler door, and also don’t feed pellets into the
combustion chamber. Gearbox operating and stopping period should be set into the system such as a
program. These settings depend on many parameters such as the boiler flue characteristics (stack
draught), working environment, thermal comfort requirement, and isolation.
All electrical and water systems must be installed by the plumbers of authorized technical services.
Installation must be done by the plumbers in order to comply with all legal and technical regulations.
DANGEROUS
This product must connect to the mains with the groundling process.
DANGEROUS
The electrical installation should be done by the technician in compliance with all legal
and technical regulations, according to the items in the manual.
ALERT
Never disconnect the power supply while the boiler is operating.
Cold water should not be added directly to the overheated boiler for any cooling purpose. This can
cause noise, overheating voltage, and indirect permanent damage.

P a g e | 8
Technopel Compact Pellet Boiler Installation and User’s Manual
Water should not be drained in the pipeline unless there is a risk of freezing or maintenance
purposes. System design should ensure that the ratio between the plumbing water flow rate&boiler
capacity, and the 20 °C difference between boiler inlet-outlet water temperatures are not exceeded.
The water level should be checked regularly and leakage should be eliminated in order to minimize
water loss.
Because adding excessive water to the system causes accumulated limescale on the water part of the
boiler. This may cause partial overheating and damage to the boiler, as well.
In case the exhaust pipe or the fresh air opened to the outside, the ends of the pipes must be
covered with a flue cap. A flue cap that avoids rain should be used for chimney pipe. If both flue and
fresh air pipes are horizontal, distances between two pipes should be at least 1 meter in order to not
draw stack gases.
ALERT
The fuel tank must be added before the fuel runs out.
ALERT
The fuel tank cover must be kept closed.
WARNING
The cold water should not be directly added to the overheated boiler for any reason of
cooling purposes.
ELECTRICAL CONNECTION
ÜNMAK Technopel Series Pellet Boilers requires 230 V~50 Hz electricity supply. The regulator should
be used in the place that <10 % or >10 % of the mains voltage. All wiring and additional grounding
outside the boiler must comply with local electrical wiring regulations. The heating system (room
thermostat connection, frost protection thermostat, etc…) must be proper to use in mains voltage.
The control cabin must be connected to a wall panel with proper grounding equipment. All electrical
connections should be made by authorized technical service personnel in accordance with local
regulations.
The grounding installation is different from column assembly and must be done separately for each
boiler room. Grounding installation should be as follows:
a) 0.5 m 2, 2 mm. thickness copper plate,
b) 0.5 m 2, 3 mm. thickness hot dipped galvanized or
c) Solid electrode copper bar
Electrode copper bar should be at least 1,5 m diameter Ø16 mm or lower than Ø20 mm at least 1,25
m diameter and the ground resistance of the electrode bar should be below the 20 Q limits. (Neutral-

Warning Against Corrosion of Installation
Please make sure that ÜNMAK boilers are highly resistant to corrosion. However, all ferrous
components at the heating installation (including pipes and panel radiators) should be protected
against corrosion. Oxygen in the installation water causes corrosion on iron surfaces as a result of
oxidation and this situation may cause material loss.
The accumulated air during the first filling of the installation must be evacuated. In general, if the
necessary precautions are taken after the first filling, no damage will occur because of the oxygen in
the water. Oxidation occurs mainly due to oxygen entering the heating water during operation.
Leakage in the system causes the addition of oxygen to the central heating water. For this reason,
the minimum water pressure in the closed expansion tank system should be higher than the
atmospheric pressure. The working pressure should be periodically checked.
Warning Against Freezing
Entire heating system must be isolated. The external parts must be insulated more than the internal
parts of the installation.
Precautions for New Installations
The design and size of the system must be done correctly to minimize water addition. No material
used in the installation should be the gas transmissions. A synthetic or max. a 50-micron metal filter
must put to the additional water line. Installation system pressure should be higher than atmospheric
pressure in closed expansion tank system.
WARNING
Fresh water should be added to the installation only if the installation temperature is
cold.
Precautions about Central Heating System connected to the Old Installations
A protective layer (black magnetite) forms on metal surfaces due to water contact in a long-time-
used heating system. The clean surfaces of the boiler will be the first place where corrosion begins if
a new boiler is installed to the old system. For this reason, please follow below items for central
heating system when a new boiler connected to the old installation system:
1. Please carefully wash the old installations for remove the dirt or residue before connect the boiler
2. A manual air separator should put on the system
ALERT
Pipeline must wash few times before assembling the new boiler to the old installation
system.
The old chimney layout should be clean before installation.

MAINTENANCE & CLEANING PROCESS
DANGEROUS
Regular maintenance is required
by the authorized technical
service for effective use of the
boiler.
Regular Controls:
• Please always check water level. Water pressure of the manometer should be marked after first
filling. the pressure rises when the water warms. For this reason, the marked water pressure level on
the manometer should be checked when the water is cold. If the water pressure is below the static
pressure or lower than the system setting, water must be added to the system while the boiler is
cold. In order to protect the system and the boiler from corrosion, the feeding water should be
softened according to the local settings. Please consider the below items during regular controls:
• Please check the front door is closed properly and replace the cover gaskets if necessary.
• Ensure that there is no gas leakage in the flue connection, if there is, it should be solved
immediately.
• Please check the fan work properly. A periodically balanced fan may run noisy.
