Valve safety cap should be loose, not too tight, so that the air could freely leave the boiler and remain of
installation.
11.4. EXPANSION TANK
Furnace has built-in expansion tank with 10l volume. Function of the tank is pressure stabilisation in the boiler and
in the heating system installation. Factory setting of the pressure in the tank is 1 bar.
11.5. FILL AND DRAIN COCK
Purpose of the cock is filling and draining of the installation.
It is positioned on the rear bottom side.
Inlet connector is R1/2", and outlet connector has hose extension.
12. FILLING THE INSTALLATION AND PUTTING INTO OPERATION
Before heating season, entire heating system should be filled with water, ventilated, and the stove should be
properly connected to the chimney, following above mentioned explanations.
Working water pressure is recommended to be 1 – 2 bars. Ideally between 1.2 and 1.6 bar.
Test pressure can reach 2.4 bars.
NOTE:
Furnace must not be used without water. It must be connected to the installation system with radiators with
minimum power of 8 KW.
13. PRACTICAL GUIDELINES FOR USING HEATING SYSTEM
-All connectors must be properly sealed and tightened. There must not be any water leakage.
-Complete installation should be checked with water under the test pressure of 2.4 bars before putting into
operation.
-System should be drained at least once because of the dirt inside it.
-Make sure that all valves between furnace and installation are open.
-Make sure to release air from the boiler and heating system prior to putting into operation.
-During ignition and cooling fazes, furnace might change in volume in response to a change in
temperature and that might cause crackling noises. That is absolutely normal, since the construction is
made out of steel and it could not be considered as deficiency. A basic fabric setting guarantees proper
functioning and prevents overheating.
14. FILLING WITH WOOD PELLET
Furnace is filled with fuel from the upper side by opening the lid. Put the wood pellets into the furnace; its capacity is
approximately three 15 kg bags.
To simplify this procedure, split it to two segments:
-Put the half of the bag into the furnace and wait until pellets reach the bottom. Ignite the furnace.
-After the furnace starts to work normally, add the pellet as needed.
-Never remove the safety grill from the reservoir. During pellet filling, make sure that the pellet bag does not get in
touch with hot surfaces.
15. DESCRIPTION AND FUNCTIONING OF THE FURNACE OPERATION CONTROLLER
