AIR HEATER 

The air may also be distributed by means of ducts, which 
are appropriately connected to the outlet from the heater. 
The ducts must ensure the required air flow. 
After the cup or ducts distributing the hot air are connected, 
check whether: 
• Fan motor does not consume more power than the 
permissible maximum value. 
• The incineration chamber and the hot air exchanger are 
sufficiently cooled off and there is no overheating. 

 
CONNECTION OF THE EXHAUST CHIMNEY 

The heating efficiency and the appropriate functioning are 
directly related to the proper chimney draught. Make sure 
that the distance between the heater and the chimney is as 
short as possible, and do not create closed bends or 
limitations in the chimney part. If the heater is not 
connected to the external chimney, equip it with a vertical 
steel exhaust duct. 
 

OPERATION 

SWITCHING ON THE HEATING MODE 

• Set the change-over switch (2) in the “0” position, connect 
the heater to the electrical socket (see table with the data 
for electrical voltage). 
• If the heater is to be switched on and off manually, set the 
change-over switch (2) to the     position, the burner will be 
switched on and will heat up the incineration chamber, after 
the temperature set on the thermostat TV is exceeded, the 
air fan will be started up. 
• If the air water heater is to be controlled automatically by 
means of a room thermostat or a time-clock, set the 
selected value on the control device, then adjust the 
change-over switch (2) to the    position, the heater will now 
be switched on and off automatically in conformance with 
the settings on the control device 
• If the heater does not function property after performance 
of these activities, the reason for defective functioning may 
be found in chapter NOTICED DEFECTS, CAUSES AND 
METHODS OF REMOVAL 
 

SWITCHING OFF THE HEATING MODE 

During the manual and automatic control, set the change-
over switch (2) to the “0” position. The burner will switch off 
and the fan will stop only after the incineration chamber and 
the hot air exchanger are appropriately cooled off. 

SWITCHING ON THE VENTILATION MODE 

In order to use the heater as a fan exclusively, adjust the 
change-over switch (2) to the         position

MAINTENANCE 

The heater requires regular cleaning and maintenance. 
Before starting the cleaning and maintenance, always 
switch off the heater from power supply. 

 
CLEANING THE INCINERATION CHAMBER AND THE 
EXCHANGER 

This activity must be performed minimum once a year or if 
needed, after the heating season is finished. Remove soot 
from the incineration chamber and the heat exchanger.  
The reason for production of the excessive quantity of soot 
may be the defective exhaust chimney, bad setting of the 
burner or bad fuel quality. The excessive quantity of soot 
may be recognised by the fact that the heater will switch off 
itself automatically. The access to the incineration chamber 
(Fig.2) and the exchanger (1) is possible after unscrewing 
the burner (2), removing the housing panels (3, 4,) and the 
panels closing the incineration chamber (5, 6). 
 
 

WARNING: By no circumstances may the heater be
switched off by pulling out the plug from the 
electrical socket or by cutting off power supply. 
Such a way of switching off the heater may lead to 
its serious damage.

WARNING: The device must be installed in 
accordance with the regulations applicable in a 
given country, and may be started only in a room 
which has been appropriately aired. 

WARNING:  As the closing panels (5, 6) are mounted 
again, pay attention to the way in which the sealing 
rope is laid, it should be spread uniformly on the 
whole circumference, in order to ensure tightness.
