The base of the burner box is formed by a shell in which the particular components are mounted. The
burner box shell is divided into two parts – burner chamber and control section. The neck with a flange
is mounted to the burner chamber enabling the connection to the radiant (combustion) tube.
There is the control valve
in the control section (with connection tube, controlling automatics
(ignition system) and air manostat for the low pressure control*. The connection tube goes
from the burner box and serves for the connection to the gas distribution. This section is closed by door.
In the burner chamber, there is the burner with a jet whose opening depends on the burnt gas and the
output. The burner is fixed to the gas valve and is directed to the neck. On the shell there is the holder
with electrodes (ignition electrode and ionisation sensor) that are inserted into the relevant holes in the
neck. On the top of burner chamber there is air intake neck with adjustable aperture used to control the
quantity of combustion air. There are three lamps on the shell – green lamp for „POWER SUPPLY“, the
red lamp for „ERROR“ and orange lamp „OPERATION“. Also the connectors for burner box and exhaust
box and control panel connection are mounted on the shell.
1. Disconnect the burner box and the electric
supply by removing the large connector
X1-X1’ and close the gas supply.
2. Disassembly the upper case and the cover
(4x stud bolt).
3. Disassembly the electrode holder (2x
screw and nut M4).
4. Disconnect the electrodes and the cables.
5. Perform the electrode replacement.
6. Perform the assembly in the reverse order.
7. Check the electrode setting according to
Fig. 43.
1. Disconnect the burner box and the electric supply by removing both connectors, and close the gas
supply and disconnect from the gas distribution.
2. Disconnect the burner box and the radiant tube (remove the clamp and pull).
3. Perform the electrode disassembly (do not disconnect the electrode cables).
4. Dismount the burner and the nozzle in the front section.
5. Perform the assembly in the reverse order. The thread is tightened by teflon band.
After each conversion, the appliance must be put back into operation by a service technician trained and
authorized by MANDÍK, a.s. Repairs and reconstructions may only be carried out by a person author-
ized and trained by MANDÍK a.s., who has valid gas and electrical certificates.
