AIR HEATER

7 

DESCRIPTION 

The heater is intended for application in small and medium-
size rooms in which the permanent heating system is 
necessary. In the heater’s incineration chamber, fuel is burnt 
and hot exhaust fumes which flow through the ducts of the hot 
air exchanger, are produced. The exchanger is fanned with air, 
which is heated from its surface. The incineration chamber and 
the hot air exchanger are constructed in such a way that the air 
fanning the exchanger is not mixed with exhaust fumes. Owing 
to this we obtain clean hot air. The cooled exhaust fumes are 
discharged outside through the exhaust fume outlet which 
must be connected with the chimney. The chimney must be big 
enough to ensure correct and effective discharge of exhaust 
fumes. 

GENERAL RECOMMENDATIONS 
 

 
The heater is equipped with a special fan burner. While using 
it, observe all the local regulations and requirements. Apart 
from this, remember: 
• to read the operating manual accurately before the 
installation and operation of the heater, and strictly observe the 
recommendations included in it. 
• to use the heater only at places, where there are no 
inflammable materials. 
• to ensure easy access to the fire-fighting equipment for 
persons operating the air water heater. 
• to use the heater only at places which are well aired. 
• to place the heater on an even, horizontal and hardened 
surface. 
• to check the heater before starting it and to regularly check it 
during operation. 
• to keep the children and animals away from the heater. 
• to always switch off the heater from power supply when it is 
not used. 
• to not connect the heater to a different burner and to not 
increase the efficiency of the burner above the maximum 
heating power, which is specified in the technical specification 
and on the rated plate. 
• to not block the air inlet and outlet, as it could lead to 
overloading the fan motor and in consequence, to overheating 
the device. 

The heater is equipped with three protection devices, which 
are started in the case of serious irregularities in the operation 
of the heater: 
• Thermostat protecting against overheating (TSS): 
switches off the burner when the air flow is insufficient for 
cooling the incineration chamber, after the chamber is cooled 
off, the thermostat switches on the burner again. 
• Thermostat protecting against overheating (TS) which is reset 
manually: it becomes operable when 

the temperature of the incineration chamber increases above 
the set maximum value (this value is higher from the TSS 
thermostat), in the case of operation of the thermostat, the 
control lamp (9) will be switched on and the heater will stop 
operating. 
• The thermal relay (RT): is started when the fan motor begins 
to consumer power exceeding the permissible maximum value. 
The control lamp (10) is lighted and the air water heater stops 
operating. 
On the other hand, the burner is equipped with a photocell 
which cuts off the fuel inflow in the case of flame decay. Then 
the reset lamp, which is located in the motor housing is lighted. 
If any of these protecting devices started to operate, before the 
heater is switched on again, it is necessary to determine the 
cause and remove it (see NOTICED DEFECTS, CAUSES 
AND METHODS OF REMOVAL). 

INSTALLATION 

 
CONNECTION OF POWER SUPPLY AND SETTINGS 

 
Each heater is supplied as a set with control and protection 
devices, which are necessary for its proper functioning. The 
distribution board, the burner and the fan thermostat and the 
overheat protection thermostats have already been connected. 

Perform the following activities: 

• Connect the heater to the electrical socket. Table 1 provides 
information concerning the supply voltage. 
• Connect the auxiliary equipment (accessories) such as: 
room thermostat or controller, to the distribution board (socket 
No. 8). 
Check the setting of the fan thermostat (TV). It should be set to 
40°C. 
When the heater is started for the first time, measure whether 
the heater does not consume more power than the permissible 
maximum value. The value is specified in the technical 
specification and on the rated plate. Also, check whether the 
fan blades turn in accordance with the direction specified on 
the fan by means of an arrow. 
When the improper operation of the burner is discovered, 
adjust it acting in accordance with the recommendations of the 
”burner operating manual”. 
 
 
 
 
 

 
CONNECTION OF THE CUP OR AIR DISTRIBUTION DUCTS 

The cup distributing the hot air (Fig. 1) may be mounted on the 
heater as an auxiliary accessory. The cup has four inlet 
openings, two of which may be blocked with covers (1,2) 
screwed up to the cup housing by means of tapping screws. 

WARNING: The heater should be connected to the earthed 
electrical socket, secured with the differential-current 
switch. 

WARNING: The works listed below may be performed
by a qualified employee of an authorised technical 
service exclusively. 

WARNING: The heater should be connected to the 
earthed electrical socket, secured by a differential-
current switch. 

WARNING: It is allowed to use burners selected and 
supplied by the manufacturer exclusively. In the case of 
application of a different type of a burner, there is a 
probability that the safety requirements will not be 
fulfilled.
