The appliance operates based on direct heater principle, that means the heater air is blowed into the heated room directly for assuring of

way making the heater air,which is blowed into the heated room (by direct blowing or through air duct) in order to ensure the keeping of
The heating and consumption values to be found as per appliance and gas types in the enclosure 1.b.
The supply of combustion air of appliance can be realized in two ways:
directly from the heated place (A,C)
from open air (CL), it can be used in case of such plants, which are working with dangers materials as follows: painting work-
shops and workshops,which are using explosive or corrosive materials etc…
fan circulates the sucked inside or outside air through the heat exchanger assuring the needed warm air for heating� (the heater air is
average 50°C)
The air supply of blower fan can be solved in two ways:
by direct sucking in from the heated place (A, C, CL types),
by sacking in from outside (CL type)�
The made warm air can be passed into the heated place in two ways:
by direct blowing in through the leading lamellas (A, C types),
by blowing in and leading through air duct to the demanded places (in this case there are no lamellas on the device)�Such as
the C and CL type of GTV�

extra maintenances but to be able to preserve the long lifetime of appliance it is recommended to have yearly supervision done with a
Maintenance supervisions by the costumer: (recommended half a yearly)
supervision of circulating fan, if needed clean it (by high pressure air),
supervision of outblowing apertures (lamellas)
supervision of suspension points/surfaces by survey
WARNING! Before every maintenance the appliance must be detached from the electrical supply
by switching off the main-switch and disconnecting the connection plug located on the back side
of appliance!
ATTENTION! In case operational circumstances of appliance (atmosphere is contaminated with cor-
rosive substances,dirt) need it, then supervision and cleaning may have done more often! The main

check of the condition of pressure regulator
check of the protective ground
check of the electrical connection
check of the exhaust fan and circulating fan: check the free rotation of fan and remove the possible contaminations from the
impellers
supervision of the heat exchanger
supervision of working of the temperature controller
check of the exhaust fan and circulating fan, if necessary clean those
ATTENTION! After every maintenance the appliance must be again adjusted !
Constructional components,which ensure the suitable operation:
• double-closed solenoid valve
• automatic burner control
• electrical board (sign processing)
•
• exhaust fan
• combined thermostat (bimetal),
• heat-limiter thermostat (100oc),
• circulating fan
Never change the original adjustments what the expert made!
Never allow that water or water –vapour can be got on the appliance!
Apart from cleaning of exhaust fan and circulating fan the a�m� components do not need maintenance! The cleaning of fans is expe-
dient to carry out by high pressure air�
