1. INTRODUCTION

1.1. Obligations of the user and guidelines concerning safety

To assure operational safety and maintain optimum operation

of the equipment:

• read the manual of the boiler, controller, feeder and observe

their guidelines,

• the manual should be kept and stored in a safe place in the

boiler room allowing using it during any moment of boiler

operation,

• ensure that the drive is never operated by children or persons

who have not read the contents of the manual and adults

with disabilities preventing them from the safe operation,

• the system should be made in compliance with the applica-

ble regulations and in accordance with the rules and recom-

mendations contained in the manual,

• before setting and connecting the boiler check whether all

components are in good working order and whether the

boiler has a complete equipment for servicing and cleaning,

• the boiler should be cleaned on regular basis, at least once

per week, removing a layer of deposited soot and ash, which

reduces the eciency of the boiler,

• ensure continuous access to the equipment,

• avoid exceeding water temperature in boiler over 95°C,

• maintain operating pressure not exceeding 2 bar.

NOTE! Boiler installation in accordance with the applicable

standards and regulations and rst start-up should be car-

ried out by a qualied installer.

1.2. Selection of correct power of the boiler

Nominal power of purchased boiler (that is maximum ther-

mal eciency, which can be reached during continuous use

maintaining the eciency declared by the producer) should be

selected in a way corresponding the real demand for thermal

energy even in case of occurrence of very low temperatures.

Do not purchase boiler with power higher than this planned

in the design. Selecting boiler with too high power will result in

higher fuel consumption and lack of full control over the com-

bustion process and therefore higher operation costs, while too

small boiler will not ensure sucient power necessary to heat

up the building.

Approximate boiler power can be calculated using a pow-

er calculator on our website www.pereko.pl Furthermore, you

should also consider: thickness of walls and insulation, the

thermal permeability of rst x joinery (including: tightness of

windows and doors, type of window panels used) and climatic

zone, where the heated building is located.

2. TECHNICAL DESCRIPTION

2.1. Intended use

Steel heating boilers Q-PER are intended for installation in the

central heating water systems in single-family houses, garag-

es, maintenance rooms etc. These boilers belong to a group of

low-temperature boilers and are not subject to registration in

the regional Oce of Technical Inspection. They are intended for

operation in water distribution piping of the gravity hot-water

systems or in open systems with forced circulation, which are

equipped with protections in compliance with the requirements

PN-91/B-02413 applying to the protections of the open water

heating system (considering the Regulation of the Minister of

Infrastructure, Journal of Laws of 2009 no. 5 item 461).

2.2. Transport and storage

Central heating boiler type Q-Per with feeding unit the fuel is

delivered in assembled condition. All the set is foiled and placed

on a transport pallet. The boiler should only be stored indoors

roofed..

2.3. Design description

tains: assembled boiler with a feeder and hopper in the casing,

electronic controller, brush, hook, ash shovel, exhaust gas swirl-

ers and ash drawer.

3. BEFORE START-UP

3.1. Boiler room

• It should be a separate room with height not lower than

2.2 m in the newly constructed building (in the already ex-

isting buildings the allowable height equals to 1.9 m).

• It should have articial lighting installed and have natural

lighting as far as practicable.

• It should have gravity ventilation in good working order,

including:

1. air-supply duct in the external wall with cross-section

not lower than 50% of chimney cross-sectional area on

height maximum 1 m over the ooring or not lower than

200 cm2 for boilers with power up to 25 kW or 400 cm2

for boilers over 25 kW,

2. separate air-exhaust duct on the internal wall with

cross-section not lower than 140×140 mm with an out-

let located under the boiler-room roof near the chimney.

• Floor gully and oor with 1% slope towards the outlet

should be planned in the central part of the room.

• Flooring and walls in the whole room should be made of

non-combustible materials.

• The doors to the boiler room should open outwards.

NOTE! It is forbidden to use mechanical exhaust ventilation

in the room where the boiler was installe.

3.2. Boiler setting

The boiler requires non-ammable ooring, in form of a founda-

tion, but it is allowed to place it on non-ammable wall base with

height not lower than 50 mm. Boiler should be placed in a way

ensuring free access to the equipment, allowing its cleaning and

maintenance. Therefore, while setting the boiler it is recommend-

ed to maintain minimum distances from the individual walls:

• distance from the front of the boiler to opposite boiler room

wall should not be smaller than 2 m,

• distance of boiler side from wall of the boiler room should

be lower than 1 m,

• the distance of rear part of the boiler from the wall of the

boiler room should be equal to at least length of the connec-

tion, that is 0.25 m.

8Page Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.

3.3. Connection to chimney

1. It is necessary to prepare stand-alone, tight chimney ue,

which will be used for ue gas from the boiler.

2. The ue should be placed at least 1.5 m over the roof ridge

to avoid the occurrence of backdraught. The intersection of

the ue should be appropriately selected for the boiler pow-

er and height of the chimney. Approximate calculations of

chimney height and intersection can be carried out using

a chimney intersection calculator available on the website

www.pereko.pl Regardless of the results of the calculations

the minimum intersection of masonry chimney should not

be lower than 14 × 14 cm! The intersection of non-insulated

steel chimneys should be bigger by 20% and the chimneys

made from steel pipes should be about 15-20% higher than

brick chimneys.

3. Check condition of the chimney (preferably by a chimney

sweep) before connecting the boiler to the chimney and

check whether the chimney if free from connections of the

heating elements.

4. The boiler should be connected with chimney using a con-

nector. It is not recommended to use the connection at a

straight angle because it will cause a loss in the chimney

draught. Flue with chimney should be joined with a connec-

tor made of steel sheet of thickness 3 mm (to be purchased

from the boiler producer). We put it on the outlet from the

ue, x on the chimney and seal with high-temperature

silicone. The connector should be directed slightly up-

wards from 5° to 20°. If boiler ue will have a length over

400 mm then it is recommended to insulate it with a thermal

insulation.

NOTE! Boilers should be installed in compliance with the

applicable Regulation of the Minister of Infrastructure

(Journal of Laws of 2002 no. 75 item 690 and Journal of

Laws of 2009 no. 56 item 461.) In addition, it is recom-

mended to use chimney liner resistant to corrosion: chem-

ical, pitting, intercrystalline and surface.

3.4. Connection of central heating and domestic hot water system

3.4.1. Open water heating installations

The Q-PER boiler is suitable for supplying open water central

heating systems with gravitational or forced circulation. The

system in which the boiler operates must meet the require-

ments of the Polish standard PN-91/B-02413 Ogrzewnictwo

i ciepłownictwo – Zabezpieczenie instalacji ogrzewania wod-

nego systemu otwartego – Wymagania / Heating and district

heating Protection of open water heating installations – Speci-

cations/. The manufacturer reserves the right to introduce design

modications.

3.4.2. Closed water heating installations

The Q-PER boiler with automatic feeding may be used in closed

water heating installations, provided that:

• the system is equipped with a membrane expansion vessel,

• a heat excess extraction device (REGULUS DBV – 1 dual

function cooling valve) is installed,

• max. 2.5 bar safety valve is installed.

NOTE! These devices must be inspected at least twice a year.

The rst inspection must be conducted during the seasonal

boiler start-up with the water heating installation.

3.4.3. 4-way valve

The design of the heating system must include boiler protection

against return of excessively cold water from the installation. Use

of 4-way mixing valve is recommended. It allows increasing the

temperature of water returning to the boiler. The 4-way valve

mixes warm water from the feeding circuit with colder water

from the heating circuit return, and therefore:

• protects the boiler against low-temperature corrosion and

preliminary wear,

• increases the eciency of heating of domestic water in the

DHW tank,

• allows exible control of heating water temperature in rela-

tion with the heating system requirements,

• increases the eciency of the entire system.

Design and installation of a heating system appropriate for a

given building must be performed by properly qualied persons.

Central heating systems may be dierent, thus the guidelines

included in the central heating design must be followed. A sam-

ple scheme of boiler connection with the central heating and

domestic hot water systems in an open heating system with

gravitational or forced water circuit is presented on page 13.

3.5. Connection of the boiler to electrical system

Boiler room should be equipped with electrical system with

rated voltage 230/50 Hz in compliance with the applicable reg-

ulations. The system should be terminated with plug-in socket

equipped with protective conductor contact with connected

protective conductor terminal PE to protect against electric

shock.

3.6. Filling the system with water

3.6.1. Filling the boiler with water

before rst start-up

1. Flush heating system and boiler before lling it with water to

remove all contaminations.

2. Fill the system with water through the drain cock using the

exible hose. Water intended for feeding the heating boil-

er should meet the requirements of the PN-93/C-04607

standard. Quality of water lling the central heating system

inuences its durability therefore this water should be free

from the contaminations, oil and aggressive chemical sub-

stances. Water hardness should not exceed 2-4 (mval/l). Too

hard water causes deposition of sediment in the boiler and

heating system what decreases eciency and may damage

the boiler.

3. Stop feeding of water when the system is full that is water

will start owing out from the signalling pipe of the ex-

pansion vessel located in the highest point of the system

or when the pressure gauge indicates 5 bar. Relling should

take several seconds to make sure that the water ows down

from the vessel.

4. Close boiler drain cock and disconnect exible hose from the

equipment when the system is lled.

PageOperation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.

3.6.2. Relling the system with water

Heating system with open container allows direct contact of

heating water with the air what results in evaporation and ne-

cessity to rell it.

NOTE! It is forbidden to add cold water to hot system. Add-

ing water to hot components of the boiler may damage it

and is synonymous with loss of the warranty..

The system can be relled with water only when the boiler is

cold. Firing up should be restarted after lling the system.

3.6.3. Draining water from the system

It is not recommended to drain the water from the system after

the heating season because it increases the risk of occurrence

of the corrosion and formation of boiler scale. The exception

is a time needed to carry out necessary repair and long-term

standstills of the boiler during strong frosts. In the latter case it is

recommended to drain water from the system (to avoid freezing

and therefore damaging to the system) and relling it with wa-

ter when the frost is over.

4. SERVICE MANUAL

4.1. Safe operating conditions

To maintain safe operating conditions for the boiler you should:

• Execute heating system correctly in compliance with the

requirements of the standards: PN 91/B-02413, applying to

the protection of open water heating installations, consider-

ing the Regulation of the Minister of Infrastructure, Journal of

Laws of 2009, no. 56, item 461.

• Fill the system with water correctly. Do not rell the system

with cold water during operation of the hot boiler.

• It is forbidden to operate the boiler if the water level in the

system is below the level indicated in the central heating

system user manual.

• Never use ammable liquids, e.g. petrol, for ring up.

• Do not extinguish the re in the furnace by pouring it with

water.

• Use suitable equipment and protective clothing (gloves,

goggles, head protection, shoes) during work with the boiler

and take special care during servicing of non-insulated com-

ponents (e.g. doors), which may heat up to high tempera-

tures resulting in risk of burn injuries.

• Do not stay on the side of the boiler during the opening of

the doors and pay attention to ames.

• Take care of cleanness in the boiler room, ensure proper

ventilation and remove corrosive and ammable materials

located nearby.

• The boiler should be cleaned only when it does not work.

• Use mobile lamps supplied with a voltage lower than 24V

during works connected with servicing of the boiler.

• Take care of the good condition of the boiler and hydraulic

system.

• Take care of boiler cleanness.

4.2. Before rst use

Before starting up the boiler for the rst time:

1. Verify correct installation and power system connection of:

• 4-way valve actuator (if used),

• central heating pump, DHW and oor heating pump (if

used),

• boiler sensor,

• fan,

• feeder.

2. Check the heating system:

• check tightness, inspect for any leakages from the boiler

or the installation,

• check for any frozen water in the pipes and the expansion

vessel,

• control proper and sucient water level and pressure

(depending on the building height, the pressure gauge

should indicate 0.8 to 1.5 bar). If water pressure is too

low, rell water (only when the boiler is cold).

3. Close the upper inspection door and feeding hopper tightly.

4. Check if the boiler is properly connected to the chimney.

5. Perform chimney draught measurement.

PageOperation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.

4.3. Boiler ignition

1. Switch on the controller (see: Boiler controller operation

manual) and activate manual work mode,

2. Check operation of individual devices: fan, feeder, central

heating pump activation,

3. Fill the hopper with a proper fuel and close tightly,

4. Switch on the fan. The feeder starts to supply fuel for approx.

2-3 minutes in manual mode. Wait until the fuel appears on

the cast-iron burner grate.

5. Ignite fuel using wood chips placed manually on the grate.

6. After ignition, set proper parameters on the controller (boiler

operation temperature, feeding time, feeding pause time

and blow-in force), according to the values specied in the

controller and feeder operation manual.

CAUTION! Burner door must be tightly closed in the auto-

matic boiler operation mode.

CAUTION! Do not set boiler temperature above 57°C!

It increases the possibility of “dew point” appearance,

which accelerates low-temperature corrosion of the heat

exchanger. Maintaining water supply temperature below

57°C when using inappropriate solid fuel types leads to

intensied boiler wear and lowers the its eciency.

After boiler ignition, entire control of the combustion process

is taken by the controller (see. Controller instruction manual)

that maintains the set water temperature in the boiler with ref-

erence to the heat demand of the building.

4.4. Approximate parameters of the controller

The controller is pre-congured, but its input parameters

change depending on the fuel used and may require individual

adjustment. Any adjustments shall be made depending on the

heat demand, type and quality (caloric value) of coal, or de-

pending on the size of the heating system.

Setting appropriate parameters ensures economic fuel con-

sumption. The adjustment consists in setting the feeding pause

proper for the heat demand. If the boiler does not reach the set

temperature, the feeding pause must be gradually shortened,

increasing the blow-in force. In the opposite situation, when the

boiler reaches the set temperature easily or starts to discharge

unburnt fuel, the feeding pause must be extended to provide

more time for fuel combustion, and the blow-in force must be

reduced accordingly. The blow-in force shall be adjusted based

on ame observation. Properly adjusted blow-in force gives

bright-yellow ame. Too weak blow-in force results in red ame

and occurrence of black smoke. Excessive blow-in force results

in short white ame.

4.5. Fuel relling

In order to ensure continuous boiler operation, the hopper must

be systematically relled. In case of fuel shortage, the controller

shuts down the entire system and displays a fuel shortage warn-

ing. While relling fuel, switch o the fan using the controller

button to prevent smoke backow to the hopper.

CAUTION: During the loading, make sure that fuel is free

of impurities that might block the feeder (rubble, stones,

wood fragments or metal scrap).

4.6. Boiler stopping

Switch o the fan using the controller button, then scrape the heat to the ash pan using the hook supplied along with the boiler.

4.7. Cleaning and maintenance

Keeping the boiler clean is necessary for its reliable and faultless

operation. Even a thin layer of deposit impairs the recovery of

exhaust gas heat, which results in lower boiler eciency. Ac-

cumulated deposit may be the cause of damage to the device.

In order to prevent that, the boiler must be thoroughly cleaned

at least once in a week. After damping and cooling down of the

boiler, remove soot from the combustion chamber and the up-

per part of the heat exchanger using a wire brush and a scraper.

Remember also about the systematic cleaning of the air

chamber of the burner, the ash accumulated in it can block the

air supply to the burner, which hinders the correct burning of

fuel and causes excessive soot formation

4.8. Emergency stopping of the boiler

Always stop the boiler in any of the following situations:

1. water leakage from the boiler,

2. temperature increase above 90°C,

3. necessity to rell the evaporated water in the system and

radiators.

In order to stop the boiler operation, perform the procedure

described in “Boiler stopping” section. Should it be necessary

to stop the boiler immediately, remove the heat using a metal

shovel and place it in a metal container. Bring it outside the boil-

er room and put out with water.

CAUTION! Do not extinguish hot fuel with water inside the

boiler room!
