DESIGN AND PRINCIPLE
WORK DEVICE
Gas supply system : For the safe operation of the
device, the network gas pressure must be at least 30
mbar, but not exceed 60 mbar.
After connecting the gas connection kit to the
network and the device, open the gas tap, after
which the gas will begin to be supplied through the
gas filter, solenoid valve, nozzles into the
combustion chamber.
Air supply system : The motor will turn the fan
blades, which in turn will supply the necessary air
flow inside the device. The air flow created in this
way, dragging with it the heat created during the
combustion of the gas-air mixture and the
combustion products formed during this process, is
fed into the heated zone.
Ignition system : The control electronics in
accordance with the specified temperature
parameters give a high-voltage electrical signal to
the spark plug, which under this influence begins to
spark thereby igniting the gas-air mixture.
Safety and control system: For your safety, the
device is equipped with three sensors
- ionization flame control
- Airflow sensor
- overheating sensor
In some countries, such as Ukraine, Russia, etc.,
according to the requirements, it is necessary to
install a fourth sensor - a minimum gas pressure

INSTRUMENT CONTROL
The heat generator type LH is equipped with an
individual thermostat, it is located on the side wall of the
control panel on the side of the discharge fan.
Temperature scale of the thermostat: from 0 to 40 º C.
The automatic mode of operation of the device occurs
by turning on / off the device, which, depending on the
air temperature in the room in relation to the
temperature set on the device, turns on or off.
An external thermostat can also be connected to the
device. For a diagram of the connection of the external
thermostat, see. Appendix No2.
The device can operate in three operating positions :
- VENTILATION
- VENTILATION + HEATING
- HEATING
VENTILATION:
Turning on the power supply of the device, press the
white button on the control panel with the inscription fan,
the device will start the fan, and will work in ventilation
mode, in which the light signal of the white button is
constantly lit. To turn off the ventilation mode, you must
press the white button again.
VENTILATION + HEATING:
Having turned on the power supply of the device, press
the green, then the white button on the control panel, in
this case the ventilation mode is constantly working,
and the heating mode is turned on periodically
depending on the air temperature in the room in relation
to the set on temperature device.
In this position, the light signal should be lit on both
buttons. When you press the white button again , the
ventilation mode is turned off, and the device will
operate in automatic heating mode.
It is possible that when you press the white button
again, the light signal will not go out, this is due to the
fact that the shutdown was made at the time when the
fan was started in heating mode.
HEATING:
After turning on the power supply of the device, press
the green button on the control panel, in this case the
heating mode is constantly running. If only the light
signal of the green button on the thermostat is lit , this
means that the air temperature is in a room higher than
the specified one. This is
will last until the air temperature in the room drops below
the temperature set on the thermostat and the
thermostat starts the heating mode, in which the light
signal of the white button should light up. After reaching
the set temperature in the room, the thermostat turns off
the heating mode, stops the fan and the light signal of
the white button goes out.

SERVICE AND
PREVENTIVE
MAINTENANCE
Preventive maintenance
Heat generators of the LH type , in addition to inspection
and cleaning, do not require special care (see
preventive maintenance performed by the user).
However, in order to ensure the safety of operation and
a long service life, it is recommended to conduct an
annual inspection by an authorized service specialist .
User-defined preventive maintenance
(a) Inspection and cleaning of the housing of the
appliance. Remove dust from the surface of the
casing with a brush or air and make sure there are
no stains or burned parts.
b) Check visually through the blowhole the
condition of the flame retardant disc. Burnout or
disc discoloration is clearly visible in visual
inspection.
c) Check the suspensions, make sure that the load
in the suspension areas is evenly distributed. This
can be done by moving each suspension
separately.
d) Clean and check the fan: Check the rotation of
the fan shaft, whether the fan blades turn freely, if
the blades are dirty, clean them.
e ) Manually control the airflow
controller , manually switch the microswitch
several times. Check for the presence of the spring.
If necessary, air purify the controller.
If the operating conditions (contamination in the
environment, e.g. dust, fumes) require this, inspection
and cleaning should be carried out more often! The
main reason for this is that the layer of dust that is
deposited on the fan worsens the efficiency of the device
and significantly increases its weight, which is an
important factor in terms of suspension safety.
The device is suitable for heating greenhouses, in
animal husbandry (poultry houses, pigsties).
Attention: If the device is used in agriculture (e.g. animal
husbandry) or in such
