3. INTENDED USE AND CHARACTERISTICS
3.1. Intended use
Water boilers Pellet Comfort are delivered as integrated heating devices that consist of a boiler with a
capacity of 7.3 or 23.6 kW along with a burner, pellet tray and feeder. The devices are designed for heating
in buildings where there is a central heating water installation (C.O.) and/or a usable water installation
(CWU). 7-16 kW boilers are adapted to work in an open system, which means, among others, that the
hydraulic system must have an open expansion vessel with an overflow pipe and be carried out in
accordance with the applicable standards for open systems or adapted to work in the system with closed
buffer.
There are Pellet Comfort boilers where the flow of heated water depends on the type of water system and
water pumps used. The boilers are designed for use with cubic capacity of up to 700 m3.
In standard, the kit includes:
- Technical and Maintenance Documentation along with the warranty,
- Technical and Maintenance Documentation of the controller,
- rake,
- pellet tray
3.2. Information about the boiler
This manual contains important information regarding safe installation, commissioning and maintenance of
the boiler.
The boiler should be installed by a qualified installer.
In order to ensure intended use, you must adhere to the manual, information on the nameplate and
technical data. It is forbidden to install the boiler in apartments and corridors. Boilers can be installed in
accordance with local and national regulations and in accordance with safety rules described in the section
“Safety”.
Installation and use of the boiler are allowed only in rooms with constant and proper ventilation. The
boiler may be used to heat water and for indirect preparation of usable warm water.
The boiler must work at the minimum return temperature of 42÷60˚C. One must ensure this limit
temperature by using appropriate devices, e.g. thermostatic mixing valve.
3.3. Installation guide
INFO One must adhere to regulations and national standards during installation and operation.
During installation of the heating system, one must adhere to the following regulations:
• local building regulations concerning the conditions of installation
• local building regulations concerning air supply for combustion and exhaust discharge.
•regulations and standards concerning equipping the heating system with automation safety devices.

www.orte.pl
www.orte.pl
Page | 7
3.4. Operation guide
When using the heating system, adhere to the following tips:
The boiler should be working at the minimal return temperature from 42 ° C to 60 °C. Do not
exceed 80°C at the system supply.
Ensure this limit temperature by using appropriate device or its settings.
The boiler can only be operated by adults familiar with its use.
Ensure that children do not remain unattended near the working boiler.
Do not add any liquids or water to increase the power of the boiler.
Ash should be placed in a non-combustible container with a lid.
Do not place on the boiler or in its vicinity (within safe minimum distance) flammable objects or
substances (e.g. kerosene, oil).
To clean the boiler, use only gentle cleaning agents.
Do not use the boiler without the recommended operating pressure.
During the boiler operation, do not open the doors of the combustion chamber.
Comply with the operating manual.
The installer must provide the user with information about the operation and proper use of the
boiler.
Do not use the boiler in case of danger of explosion, fire, leaks of combustible gases or vapours (e.g.
when gluing linoleum, PVC etc.).
Pay attention to the flammability of construction materials.
3.5. Safety systems
Each boiler is equipped with 6 interdependent safety systems.
1. Feeder temperature sensor Installed during the commissioning in a smaller tube between the burner
and the flexible pipe connected to the feeder. The sensor informs about the backflow of fire to the tray
and an increase of the feeder temperature above 45°C.
2. Elastic tube between the metal pipe of the burner and the feeder. If the temperature sensor of the
feeder is damaged or improperly installed, the fire that goes back to the feeder dissolves the elastic pipe
within 2-3 seconds, cutting of the fire from the feeder where pellet is stored. Additionally, the elastic pipe
is not placed directly over the burner, but on the side.
3. Boiler overheating sensor. If the water temperature exceeds 80°C, the burner automatically goes into
putting-out mode. This prevents the burner from working in the case of a limited heat perception.
4. Photoelement defines the quality of the combustion process. If there is not enough air in the furnace,
the fire’s brightness drops below the pre-set level. The burner automatically goes from the maximum
power mode (feeding large amount of fuel) to the firing up mode (small amount of fuel). If the situation
does not change, the fire’s brightness remains at the level not exceeding the required brightness. The
burner will display “no fuel” error and will stop fuel supply, which will prevent excessive carbon monoxide
emission.
5. STBwith manual lock deletion.
6. The controller has a password on service parameters.

4. SAFETY
The device must be installed and accepted only by an authorized installer with confirmed qualifications.
The boiler must be installed, placed and used in accordance with applicable regulations. Strictly adhere to
the instructions contained in Technical and Maintenance Documentation. Do not install the boiler in places
at risk of fire, explosion, flooding or freezing. The boiler must be connected to an electrical outlet –
grounded and with a differential protection. The boiler is adapted to an open system, which means that
the hydraulic system must have an open expansion vessel with an overflow pipe.
Unattended minors and pets cannot be near the operating boiler.
Do not exceed maximum power. Ensure proper air circulation –in accordance with appropriate
regulations. Ensure chimney-sweep inspection in accordance with applicable regulations, not less
frequently than once every 3 months or in accordance with local regulations.
Ventilation of the room where the boiler is placed must be made in accordance with applicable
regulations.
In order to operate properly, the boiler needs fresh air and the required chimney draft.
Air should be supplied to the burner in order to carry out proper combustion processes in the boiler
chamber.
Do not connect several heating devices to the same chimney. However, if there are other heating devices
installed in the room (connected to other chimneys), supply sufficient amount of air to ensure combustion
in each device and ensure sufficient air for room ventilation, taking into account all the devices.
It is forbidden to open the device during operation due to the risk of burns.
No flammable materials allowed in the room.
Fuel storage –in accordance with relevant regulations and standards (in a different room than the boiler).
An ABC type powder extinguisher must be placed near the device.
In the event of a chimney fire, immediately put out the burner by pressing the central switch –position 0,
placed above the controller. Do not open the ash pan, cut off all access of air needed for combustion. Do

www.orte.pl
www.orte.pl
Page | 13
not open windows. Then, secure the chimney outlet using the chimney sieve. It is intended to reduce the
intensity of soot combustion in the chimney by suppressing the fire, and to prevent the escape of burning
soot from the chimney, consequently protecting the roofs and nearby buildings against fire. The chimney
sieve can be replaced with a wet cloth to cover the chimney outlet in case of fire. Damp the cloth with
water until the soot is burnt-out. Do not extinguish chimney fire with water, because rapid cooling of the
chimney and water evaporation can cause cracks in the chimney and the spreading of fire.
If the device is operating in adverse weather conditions, e.g. during an unfavourable chimney draft (too
low draft) or bad weather conditions (e.g. cold, strong wind), extinguish the device to avoid the return of
fumes. Before re-igniting the device, wait until weather conditions improve.
In the case of a longer break in operation, perform chimney sweep inspection, because there is a risk of
clogging.

5.1 Transport
The device is protected against damage in transit. During transport, loading and unloading, the device must
be protected against impact, damage, crushing and against adverse environmental conditions, as they may
cause damage to the device. In case of damage to the device in transit (consignments must always be
checked on delivery), return the device to the service department in order to remove the resulting defects.
On delivery, check the completeness of the shipment. Potential objections and problems should be
reported to the supplier who is responsible for insurance.
WARNING: Risk of injuries due to moving too heavy objects and due to improper protection during
transport!
Ensure that the boiler is lifted and moved by a sufficient number of people.
Use appropriate means of transport, e.g. trolleys with fastening belts or lift trolleys.
Secure the boiler against falling.
NOTE: Damage to the system due to frost!
Install the heating system in a room protected from frost.
INFO: Observe construction supervision provisions, in particular, the current provisions related to
furnaces, construction requirements with respect to installation rooms and their ventilation.
In order to reduce the weight of the boiler during transport, the tray and the exchanger are packed
separately.
The boiler is delivered on a pallet.
Position a lift trolley to the back wall of the packaged boiler.
Secure the boiler on the transport device with a fastening belt.

Move the boiler to the place of installation.
During transport, make sure not to damage the boiler.
If possible, transport the boiler secured on the pallet to the place of installation.
Unpack the boiler.
Dispose of the packaging in accordance with environmental protection requirements.
5.2. Installation
The Pellet Comfort boiler (if not otherwise requested by the customer) is delivered, depending on the
power and the selected tray, on one or two wooden pallets. The burner is fixed to the device. The tray is
delivered folded. The boiler must be connected to the tray as shown in the picture.
Ensure that the tray overheating sensor is inserted into a thin tube secured to the fireplace tube (stainless
steel chimney-elbow). Connect the chimney with a flexible tube, and then connect the tube with the tray
outlet.
DANGER: Putting any objects into the tray during operation of the boiler can cause serious injuries.
The tray should be covered from the top with the cover. It is forbidden to insert any objects into the tray
during feeder operation, as this may cause disability. Remember to fill up the tray with pellet before
operating the burner with the operating mode on the display set to “STOP”.
After installing the feeder inside the tray and filling up with pellet, disconnect the flexible pipe from the
burner and check the feeder usage. In order to determine the correct amount of the fuel quantity, use the
following formula: 0.2 kg / h pellet times the amount of kW of device power. E.g .: 0.2 x 24 = 4.8. The
obtained result will give us in kilograms per hour (kg / h) the information we need the amount of fuel from
obtaining the desired thermal power in kW. The burner, when working in a given cycle, should give the
amount of fuel for an hour that comes out of the formula. It is recommended that the feeder's working
cycle should not exceed 75%. So if the feeder gives, for example, 25 kg in a fixed cycle, set the FUEL FOR
MAX POWER at 19% (4.8: 25 = 0.19).
5.3. Installation conditions
In order to install the boiler, certain conditions (at the site) must be met. The user and the installation
company are responsible for meeting these conditions.
The installation site must meet the following conditions:
• Safe operation of the boiler must be ensured at the site of installation.
• The site of installation must be protected from frost.
• Installation and use of the boiler are allowed only in rooms with constant and proper ventilation.
• Ensure the supply of a sufficient amount of air.
• The floor under the boiler must have sufficient bearing capacity, and must be levelled and flat.
• The boiler can be placed only on a non-combustible surface.
The chimney must meet the following conditions:
• The chimney and exhaust gas connection must comply with applicable regulations.
• The chimney must be insensitive to moisture.
5.4. Distance from the walls

DANGER: Fire hazard due to flammable materials or liquids!
Do not place or store flammable materials or liquids in the boiler room.
WARNING: Damage to the system due to too small distance from the walls!
In case of non-compliance with the minimum distances, cleaning of the boiler is impossible.
Keep minimum distances.
Place the boiler on an incombustible surface, keeping the required distances from the walls. The surface or
foundation for the boiler must be level and flat. If the foundation is not level, in order to provide better
ventilation and flow, the side with the connection (back wall) can be placed 5 mm higher. The foundation
must be larger than the boiler base: at the front, at least 300 mm, and approx. 100 mm on other sides.
5.5. Distance from flammable materials
DANGER: Fire hazard due to flammable materials or liquids!
Do not place or store flammable materials or liquids in the boiler room.
Instruct the user to keep minimum distances from flammable materials in relation to flash
resistant materials.
5.6. Exhaust connection
DANGER: Fire hazard due to improper connection to the chimney and incorrect selection of the chimney!
Chimney sweep acceptance must be performed before operating the boiler.
INFO: The boiler draws in air needed for combustion from the environment.
Install and operate the boiler only in rooms with constant and proper ventilation.

NOTE: Damage to the system and the boiler due to insufficient chimney draft!
Ensure the required chimney draft.
INFO: Chimney draft depends on the diameter, height, surface unevenness inside the chimney and the
temperature difference between combustion products and external air. It is recommended to use a
chimney with liner.
Before connecting the boiler to the chimney, check whether the chimney diameter is sufficient and
the chimney is not connected to other heating devices.
The internal surface of exhaust pipes should be resistant to the destructive effects of exhaust gases.
An installer or a chimney sweeper should precisely calculate the chimney.
The chimney must be insulated and not shorter than 5 m (minimum 1 m protruding above the roof).
Chimney sweep acceptance must be performed before operating the boiler.
5.6.1 Exhaust connection to the chimney
INFO: The boiler must be connected to the chimney in accordance with local construction
laws and in cooperation with a chimney sweeper.

A chimney with a proper chimney draft is the main factor determining the correct operation of the boiler.
This has a significant impact on the power and efficiency of the system. The boiler can be connected to a
chimney with sufficient chimney draft –see technical data.
In order to make calculations, use the exhaust mass flow at the total rated heat output. The effective
length of the chimney is calculated from the point of entry of exhaust gases to the chimney.
Install the flue gas outlet with inspection opening for cleaning.
Mount the exhaust pipe to the chimney with a 5 mm rivet or screw, using the existing holes. The
exhaust pipe should be as short as possible and should be elevated upwards from the boiler to the
chimney.
Connect the flue to the chimney with the boiler connection (figure 3, item 32)
made of 3 mm sheet metal. Place it onto the flue outlet, embed inside
the chimney and seal.
Exhaust pipe, mounted only to the chimney and placed onto the exhaust connection pipe, should
be mounted very carefully to prevent sliding out.
Pipes longer than 2 m should be additionally fastened. All parts of the exhaust pipe must be made
of non-combustible materials.
TIP Chimneys made of steel pipes should be higher by 15-20% than brick chimneys.
INFO: Due to the low temperature of exhaust gases at the rated thermal output, the boiler can emit wet
fumes, lead to the deposition of soot, and cause insufficient chimney draft. This can lead to moisture and
corrosion of brick chimneys.
It is recommended to use a chimney liner:
–in the case of modernization of the existing chimney ducts and adapting them to year-round
operation of the boiler, it is recommended to use one-sided or double-sided (depending on the
place of installation) exhaust system made of stainless steel (acid- and heat-resistant),
–in newly-constructed buildings and in the case of year-round operation of the boiler, it is
recommended to use a ceramic exhaust system resistant to condensate, thermally insulated, with
ventilation and condensate discharge.
The boiler room should comply with the requirements of PN-87 B-02411 on solid fuel central heating
boilers.
The boiler room should be protected against the ingress of ground water and should be equipped with
adequate ventilation to ensure free inflow of combustion air, including:
–ventilation duct (a hole in the window or wall without shutters) with a cross-section not less
than 200 cm2,
–ventilation duct placed, if possible, near the chimney with an inlet hole (without shutters) under
the ceiling with a cross-section not less than 140 x 140 mm.
5.6.2. Inlet air connection
DANGER: Lethal danger caused by a deficiency of oxygen in the boiler installation room!
Ensure the supply of a sufficient amount of air through the openings leading to the outside.

DANGER: Risk of injuries/damage to the system due to shortage of combustion air!
Insufficient amount of combustion air can lead to the formation of tar and low-temperature gases.
Ensure the supply of a sufficient amount of air through the openings leading to the outside.
Instruct the user that air inlet holes must
always remain open.
5.7. Hydraulic connections
Hydraulic system must be done by a plumber with appropriate permissions, in accordance with
appropriate standards and hydraulic expertise. Each hydraulic system should be made on the basis of a
proper design and accepted by an authorized person.
NOTE: Damage to the installation due to leaking connection!
Mount connection tubes to the boiler ports without tension.
INFO: In order to ensure fuel-efficient operation, we recommend installing a buffer tray.
When using a buffer tray (buffer), combustion can take place at the optimum point of operation, both in
terms of energy use and emissions. Heat that cannot be used for heating at the time of production is
stored in the buffer. When the fuel inside the boiler is used, the heat stored in the buffer will be put into
heating circuit.
Both with and without buffer, the boiler works fully automatically. The buffer improves the efficiency of
the entire system.
5.7.1. Connecting the boiler to the central heating system
After placing the boiler and connecting it to the chimney, perform the following installation works:
connect the boiler to the central heating system by screwing the pipes (supply pipe and return pipe)
to appropriate connection stubs 1 ½”,
screw in the drain plug delivered with the boiler,
use appropriate seals to ensure the tightness of connections (tow,
seal tape etc.),
Before connecting the boiler to an old central heating system, rinse it to remove sludge from
radiators and pipes.
At the supply connection, connect the sensor and the thermal protection of hot water outflow
(additional equipment)
INFO: The thermal outflow protection (accessory) should be installed between the cooling water inflow A
or B and the heat exchanger inlet (cooling pipe coil).

A and B. Heating circuit supply connections (optional). Hot water outlet.
C. Exhaust output.
D. Drain hole.
E. Return water connection. Cold/cooling water inflow.
DANGER: Injury and/or damage to the system due to overheating!
The boiler can operate only with an active thermal outflow protection and/or safety heat
exchanger.
Always ensure that cooling water is supplied to the thermal outflow protection and safety heat
exchanger to maintain the required water pressure.
Inform the user about the operation of the thermal outflow protection and safety heat
exchanger.
DANGER: Danger to health due to contamination of usable water!
Ensure compliance with national regulations and standards on the prevention of usable water
contamination (e.g. water from heating systems).
Ensure compliance with EN 1717.
Put a filter in the cooling water inlet, in front of the thermostatic valve.
Do not place mountings allowing for the total or partial closure of the flow or devices and
mountings reducing the internal cross-section on safety pipes, expansion pipe, overflow pipe and
venting pipe.
INFO: The minimum capacity of the expansion vessel is calculated according to the formula [1] - PN-91/B-
02413 p. 2.5.1.
INFO: Equipment and placement of the expansion vessel is determined by PN-91/B-02413 p. 2.5.2.÷2.5.4.
Expansion vessel, safety pipes, expansion pipe, signal pipe and overflow pipe must be at a place where the
air temperature is not lower than 0 ° C.
INFO: If the expansion vessel is at a place where the air temperature drops below 0°C, use circulation
pipes and safety pipes connecting the expansion vessel with the boiler, as well as thermal insulation
according to PN-91/B-02413 p. 2.11. Thermal insulation of safety devices is to protect them against
freezing only during short interruptions of heating.
NOTE! –The lack of thermal insulation and placing the expansion vessel not in accordance with PN-91/B-
02413 identified during warranty claims for leaks during temperature drops below 0°C
can be grounds for not accepting the complaint and refusing to repair or replace the boiler.
