REFILLING THE CHAMBER WITH FUEL
Read and become fully familiar with the operating instructions, manual and the AK4000 electronic control.
Check water pressure in central heating system (max. 3 bar).
Connect electrical components ( example: pump, discharge fan, indoor thermostat, etc..)
Check fireclay brick supports inside the combustion chamber (pic.3)
Check metal panel covers.
Check power supply connection (230V/50 Hz) ,
Prepare a sufficient amount of fuel for the burning and heating phase.
Lower door open
Burning base
1. Connect boiler to power supply network (230V/50Hz) using the power lead.
2. Wait until the visual display basic image is activated:
a) Boiler without lambda sensor - immediately
b) Boiler with lambda sensor – around 30 secs (automatic servo-unit initialization).
3. Refer to points 4–7 and choose the configuration that matches the boiler installation with accessor
to help handling AK4000 control.
4. Set the boiler AK4000 control to deactivated phase "OFF".
5. Fuel heating:
a) using lever, open chimney (pic.3/3),
b) open upper door (pic.3/2) and place paper on the fireproof nozzle (pic.3/9)
extends to lower burning chamber (pic.3/25),
cover with woodchips, then place wood cuts on top
and fill-up with solid wood logs,
c) close upper door and open the lower door slightly
(pic.3/13) to achieve fuel heat in the chamber
(pic.3/4), if the boiler is equipped with discharge fan use for quick start.
d) when fire base is created (takes approx. 10-
15 minutes), close the lower door and chimney flap
using the lever.
6. Switch the boiler „ON“. Boiler will start combustion and will control its output automatically up to t
required temperature.
7. To refill with fuel follow steps in chap. 4–7.
8. To shut-down the boiler follow instructions in chap. 4–7.
Fuel inside the boiler moves spontaneously towards the fireproof nozzle. Ash falls through the nozzle and
is deposited in the combustion chamber. Boiler output is regulated automatically according to the set-up
temperature of outlet water. If there is a mains power cut over a long period of time or if the automatic
control fails, it is possible to heat as follows (only applicable for central heating systems with gravitation
flow): open chimney flap and open bottom door a little. If this way of heating is used, it is necessary to
check outlet temperature more frequently and to add less fuel. The boiler may easily become overheated,
if the chamber is full.
•
using lever open chimney flap (pic.3/3),
•
press „ “ button on the display (chap. 4–7),
•
open upper door with caution, to allow smoke to disappear,
•
through upper door (pic.3/2) refill with fuel as necessary
•
close upper door (pic.3/2) and chimney flap (pic.3/3),
•
by pressing „ “ button finish fuel refill
