Ignition, start-up and turning-off are fully automatized. Combustion control is optimized using algorithms such as ‘modulation’ which automatically decreases pellet dose as the difference between desired and reached temperature is decreasing. Pellets are fed to boiler via internal transporter screw inside the storage tank. From there pellets are fed over to heating chamber where they fall free to the designated melting area (the ‘actual’...

The rotation of the boiler during the shipment or installation represents a serious risk and can lead to damaging the boiler. It is forbidden to place one boiler onto another. The boiler can be stored only in closed rooms with no atmospheric influence. The humidity in the storing room also must not exceed the critical value of 80%, so as not to create any condensate.
Clean the boiler on a regular base. An expert should be entrusted with the mounting of the heating and the initial operation. This must be a person who will take over the responsibility and guarantee the correct operation of the boiler and of the complete central heating system.
Front side should have free access. Boiler base must be stable and made of fireproof material. Connecting to the chimney TOBY B is a boiler with natural draught so it requires a chimney not just to transport flue gases out of the boiler but also to create negative pressure necessary for boiler function.
Filling the system with water Filling the system with water is to be done using the tap valve connection of the boiler. When filling the system with water take care that no air remains in the boiler. The filling process is done when no air is coming out through automatic air vent and pressure gauge is showing the value between 1,5 and 2,5 bar (closed systems).
It is recommended to install a dirt catcher and also an anticondensation valve on the return line. (3-way mixing valve). CLosed expansion vessel (position 7) should be mounted close to the boiler. Vessel must be positioned so that its membrane is in horizontal position. he volume od the vessel is calculated using the ratio 1 KW :1 l.
It is essential to have a thermometer and a manometer installed to the system (Position 4 on upper scheme) It is recommended to install a dirt catcher and also an anticondensation valve on the return line. (3-way mixing valve). CLosed expansion vessel (position 7) should be mounted close to the boiler. Vessel must be positioned so that its membrane is in horizontal position.
The safety valve (with preset 2,5 bar threshold) is already mounted on the backside of the boiler and its connected directly to the boiler water jacket (Position 18, drawing in Chapter 1) It is essential to have a thermometer and a manometer installed to the system (Position 4 on upper scheme) It is recommended to install a dirt catcher and also an anticondensation valve on the return line.
1. 3-end mixing valve 2. Circulation pump 3. Thermostate The purpose of this valve is to transmit a portion of the hot water to the return line cold water in order to compensate the temperature difference between the flow and return line. Boiler cleaning and maintenance Regular maintenance and cleaning of pellet boilers is necessary to ensure product functionality and long- life operation.
However if pellets of extremely bad quality are used, the cleaning frequency can change dramatically. Boiler would not last long. What tools do I need to clean the boiler? Simple cleaning set is delivered with the boiler. However, ash-vacuum-cleaner would make things faster and easier. Before performing any of the steps described below, boiler must be turned off...

Open the main boiler door and remove the ash-tray outside the boiler. Also remove burner pot, remove the ash from the pot int the ash-tray first, then empty the ash-tray. CAUTION: SOME PARTS MAY BE HOT! Clean the area where burner pot is placed. Dont forget to clean the top of the tube where resistance heater is placed.
Release the screw-balls that hold the plate below. Clean the area inside with the ash cleaner or using manual tools. When screwing back the holders, screw completely, so that no air can pass inside. Ukoliko ne posedujetevIf no vacuum cleaner is present, use the hand tools as shown below.
Open the doors on the top panel of the boiler. There are two bars coming out. Now take the boiler KEY, mount on the bar and move up-down to release the ash from the heat exchanger tubulators. Do this for both bars. Occasional (seasonal) cleaning Necessary equipment: Gloves, Ash removing vacuum cleaner OR manual cleaning set (delivered with boiler).

Metal cap with tubulator lifters and one screw in the middle is visible. The insulation coat is attached below this metal cap. To unsrew the cap use boiler KEY. Put the metal cap aside. make sure you make no damage to the stone-wall insulation below.

With fork-key size 13 or boiler KEY, unscrew the upper cover of the heating chamber. Lift the cover and put it on side. Perform detailed cleaning of all parts that can be accessed. Remove the ash. The use of the ash-vacuum cleaner would make this job faster and easier.

After the cleaning put back the cover and screw the holders. Put everything back in its place.
