2 Safety notes

2.1 Proper use

2.1.1 Basic principles

Pelling boiler was built in accordance with safety regulations. However, its use can result in the injury or death of the user and/or third part and in impairments to the boiler itself or to other material goods.

2.1.2 Using the boil er

Use the boiler only when it is in perfect condition. Use it properly, as described in this manual. Stay aware of the safety and of the dangers involved. Have any faults which can impair safety immediately fixed.

The boiler was designed to burn wood pellet and wood. The manufacturer will accept no responsibility for any damage resulting from improper use. Proper use includes maintaining the installation, operation and maintenance specified by the manufacturer. The user may only enter or change the operating values specified in this manual. Any other entries will affect the boiler's control program and operation, which can lead to a malfunction.

2.1.3 Permissible fuel for the Pelling boi lers

Only wood pellets and wood are permissible as fuel for the boiler. Wood pellets are pressed into a cylindrical shape. They consist of untreated sawdust from the wood processing industry as well as unprocessed forestry waste. They have a standardized diameter and length and very low water content.

2.1.4 Recommended wood pellets

Thermo FLUX d.o.o. recommends wood pellets with a diameter of 6 mm and a length of 10 - 30 mm.

 Other requirements on the fuel result from either standard O-Norm M 7135,  DIN plus 51731,  UNI CEN/TS 14961

Pay particular attention to the wood pellet quality.

Pelling

2.3 Other risks of the side effects

Despite the precautions taken there are also certain risks of side effects:

DANGER OF CARBON MONOXIDE.

If the boiler is running during cleaning time may occur transmission of CO through the open door. Do not open the door longer than necessary.

2.4 Duty to inform

Reading the manual

Everyone who works on the boiler must have read the Use and maintenance manual

before starting work and, in particular, have read the second chapter „Safety notes“.

This holds especially true for persons who only occasionally work on the boiler e.g. when cleaning or maintaining the boiler. This manual must be kept ready to hand at the boiler's installation location.

Pay particular attention to the applicable local standards and guidelines.

2.5 Safety devices

Boiler is equiped with safety devices that in case of unexpected situations stop the power supply and thereby stop the operation boiler.

Boiler electronic regulation: operates directly and stops the operation of the boiler until it cools down. * In case of the suction fan failure, failure of the motor for auger (doser), black out (if the blackout was longer than 10 seconds), an unsuccessful firing.

ThermoFLUX

Pelling

Fuse F 4 A 250V : Fast fuse , protects the boiler from large voltage changes of

electricity and short circuits inside the boiler.

Safety thermo switch (STB) : intervenes by breaking the circuit in the boiler (automatically stops motor of the auger and exhaust gasses fan) if the boiler temperature reaches the limit of 95 °C.

ThermoFLUX

Pelling

3 Installation and commissioning of

the boiler

Commissioning system in the operation is performed by personnel authorized by ThermoFLUX Ltd or autorized seller.

Commissioning includes referral to operation with the basic operations and maintenance of the boiler. Authorized service for the first start, must control the functioning of the boiler at least during one full operating cycle.

Danger from material and body due to improper commissioning. If the commisioning is performed by unautorished personel, it may cause damage to the boiler and heating system.

3.1 Conditions

The following conditions must be fulfilled before the system is put into operation.

Turn OFF electrical power.

Check mechanical connections

Check that all components are properly connected Check that all mechanical components are connected. Check whether combustion chamber properly seated

Check hidraulical connections

Check whether the circulation pump and the mixing valve is properly connected.

 Check whether the safety equipment properly connected.

3.2 Chimney and flue gas pipes

The chimney should be calculated and constructed in accordance with the EN 13384-1 standard.

The venting of flue gas must be done in accordance with all applicable laws including those related to dimensions of the chimney and materials used for its production. Flue gas channel should be made of adequate materials, such as steel tubes, with various sealing.

ThermoFLUX

Pelling

In any case, materials that could potentially catch fire, e.g. wooden planks, beams, cloth, should be adequately protected with non-combustible material. For the sake of parity of dimensions, chimneys that are round in shape of the inner part should have an advantage over the rectangular-shaped chimneys.

Too small inner zone can cause irregular flow from the boiler to the top which could lead to poor boiler performance and excessive exhaust gas production that discharges the exhaust gas to the environment. Gas flue pipe should be permanently installed and it would be good to make safety door which would enable the cleaning of inner parts, especially the horizontal parts.

Smoke pipe should be installed fixed. It would be good to leave safety gates that could do the interior cleaning, especially in their horizontal parts. You should avoid as much as possible horizontal mounting parts. Horizontal parts must have a slope of at least 3% upwards. Length of the horizontal part should be minimal and in any case not more than 3 meters.

ALL PARTS OF THE FLUE GASN PIPE NEED TO BE SECURED AND REPLACEABLE IN ORDER FOR INTERNAL CLEANING.

AVOID MULTIPLE HORIZONTAL DEVIATION AND ANGLES.

3.3 Minimum distances of the boiler from wall

and objects

A – minimum distance front - 100 cm B – minimum distance from side (BOILER BODY) - 20 cm C – minimum distance back side- 20 cm D – minimum distance from side (SILO) - 40 cm

ThermoFLUX leaves itself the right to later perform changes without notice.

Water temperature indicator

Regulation on the boilers ''Pelling'' is most important electronic component. It is consisted of key controling modul set under the cover of the boiler and controling unit with display set on the front side of the boiler. With controling unit it is possible to control functions of the boiler and also to check information about present state of the boiler.

Due to the possibilty to work in 5 (five) different powers, regulation can satisfy needs to increase or decrease heating by automatic adjustment of power.

If there is a need to increase power, this is registered by regulation and regulation gives a signal to increase power by adding more pellet as well as proportional increase of air flow in the burning basket.

When desired temperature is reached (need for heating energy is satisfied) regulation is decreasing power ( modulates ), or when room thermostat gives signal that set temperature is reached, boiler then goes into SHUT DOWN mode (if mode STAND-BY is ON )

5.2 Principle of boiler operation

Principle of the boiler operation is very simple.

When button for start is pressed boiler goes into IGNITION MODE. START is displayed, and after that PELLET IGNITION. Usually this phase lasts for 5-15 minutes depending on type of the boiler and pellet quality. At that point dosing system is activated, igniter and suction fan. Dispenser is making initial dosing of pellet into burning basket. At the same point igniter starts to ignite pellet and suction fan is on and is making necessary underpressure needed for combustion. When temperature sensor for flue gasses detects that temperature in the chimney has reached necessary value, regulation then changes working mode of the boiler into FLAME STABILIZATION.

This phase (FLAME STABILIZATION) lasts for 2-3 min. (depending on the type of the boiler and in this phase igniter goes off. After flame stabilization, boiler goes into the normal working mode and changes power from power 1 to set power. On display is written WORK. On the right side set power is displayed and in the last

7 Cleaning and maintenance

To secure proper work of the boiler, cleaning and maintenance is

neccesary.

Cleaning can be divided in three stages :

 Daily  Weekly  Monthly

7.1 Daily cleaning

Depending on pellet quality, braizer basket ( burning pot ) needs to be cleaned every 1 – 3 days.

1. Turn off boiler and wait for cooling

2. Open lower and middle doors

3. Clean stockhole.

Use protection gloves to remove braizer basket (burning pot). After removal of basket clear content from it. Content should be cleaned into fireproof container. 1

4. Holes on the basket should be cleaned with proper tool to

secure air flow for combustion.

5. Return back basket into position tio fit properly on igniter.

6. Close the door before ignition.

We are suggesting waccum cleaner with metal container.
