Warsaw, on ............... 20.......... (full name and signature of the person authorised to make the declaration)
The present instruction manual is an integral part of the device, and should always accompany it.
Before start-up of the device, please read the Original Instruction Manual carefully, taking time to ensure full
understanding:
The manufacturer and retailer are not liable for the loss of health of persons or animals caused by:
- usage of the equipment contrary to its foreseen use,
- usage of the equipment not in line with the original instruction manual,
- usage of the equipment contrary to fire and occupational safety provisions in force.
1. General rules
1.1. Foreseen use
Type M and MP air heaters are foreseen for the heating and ventilation of rooms in which people remain or work. Type M
heaters are equipped with axial ventilators, while type MP heaters are equipped with radial ventilators.
1.2. Hazards stemming from improper heater use
The hot air chamber is equipped with safety devices that have been checked and tested.
Improper use of the device can be hazardous to the persons making use of it, and possibly cause damage to components
connected to the same electric circuit.
Persons installing, using or servicing the heater should proceed in accordance with this Original Instruction Manual.
Safety indications
WARNING!
This is an indication of a potential hazard. Seeing this symbol, one should pay particular attention to information found
below it. Failure to observe remarks indicated with this symbol may lead to damage to the heater or even to personal
injury.
IMPORTANT!
This is an indication of the requirement to read the information found after it very carefully, as this will contribute to safe
use of the device.
1.3. General indications
Air heaters with heat exchangers may be used in rooms, in which people remain.
WARNING!
Never install the heater in any room, in which there is any risk of explosions.
WARNING!
Exhaust fumes may cause a fire. Always maintain a safe distance to combustible materials.
1.4. Rules of safe operation
The heater with a heat exchanger burns light fuel oil or diesel oil in a closed combustion chamber. The exhaust fumes are
led to the outside through the chimney. Warm air is blown out by the ventilator. The ventilator is covered with a protective
mesh on the air intake.
WARNING!
Never use the heater without the ventilator safety mesh, as this may cause damage to persons and objects.
IMPORTANT!
The air intake and output openings must be uncovered at all times.
WARNING!
If the exhaust gases are directed straight towards any combustible material, this may cause a fire.
WARNING!
Before commencing any repairs or cleaning of the heater, remove the electric plug from the grid socket. Use the
heater only as it is supposed to be used, meaning, solely and exclusively for heating and ventilation.
1.5. Recommendations for the user
The heater should be operated by a person who, before using the device, had thoroughly acquainted themselves with this
Original Instruction Manual.
1.6. Installation suggestions
The equipment should be installed on a stable and levelled ground, protected from any sorts of obstacles that might
cause its malfunction.
The device requires the connection to a chimney system in order to ventilate its fumes. The chimney system should be
executed in line with the standards in force, by appropriately authorised persons. The minimum chimney width should not
be less than the device's exhaust gas outlet diameter. The chimney height should not be less than five metres (17 feet).
WARNING!
Before installing the device, make sure that the air inlet and outlet are free of obstacles.
1.7. Safety recommendations
The air inlet mesh protects against accidental contact with the ventilator fins.
WARNING!
The ventilator may shut off automatically. The mesh may only be removed by authorised personnel, after the
equipment is disconnected from the electrical grid by the removal of the plug from the electric outlet.

2. Heater structure explanation
The structure of the type M heater is based on a galvanised steel frame. The heating part includes a combustion chamber
made of stainless steel, and a heat exchanger. The heater outer casing is made of painted sheet steel and possesses a
thermal insulation layer made of non-flammable insulation wool with an aluminium layer. Under the combustion chamber,
in the ventilation part, there is the ventilator. The ventilation chamber is protected by a mesh.
Furthermore, the heater is equipped with the following safety devices:
- ventilator thermostat - automatically switches the ventilator on and off during the heating cycle (calibration to 40 °C)
- LIMIT - shuts burner down automatically and switches it on if the temperature of the outlet air exceeds 80 °C or if the
exhaust air temperature falls below this value.
- LIMIT 2 - safety thermostat unit, shuts down the burner if the temperature of the exhausted and reaches 100 °C. After
the heat exchanger cools down, the burner may be shut off by hand using a button on the thermostat housing.
3. Check procedure before heater start-up
The M/MP heaters are equipped with electric boxes, with the following devices.
- main switch
- work node selector switch
- fuse
- additional connections for the external thermostat.
The cover of the electric cabinet for the units requiring a 400 V power supply has additional indicator diodes:
- power supply (green)
- thermal fuse (red) - indicates that the thermal fuse of the heater fan was actuated
- limit 2 (red) - indicates that the fuse of the heat exchanger was actuated; to reset this, unscrew the cover of the
thermostat cabinet and press the button.
BEFORE STARTING UP THE HEATER, MAKE SURE THAT IT WAS PROPERLY CONNECTED TO A 400 V / 50 HZ
POWER SUPPLY LINE.
4. Starting up and shutting down the heater
4.1. Heating phase
Set the main switch to position '1', and the work mode switch to heating (Grzanie). The burner is actuated. When the
temperature of 40 °C is reached, the fan switches on automatically. When the exhaust temperature reaches 80 °C, the
burner is switched off, and the exchanger enters a cooling cycle. The cycle is repeated after the burner is actuated again
by the limit thermostat.
WARNING!
Before switching off the main switch, make sure that the heat exchanger has cooled down sufficiently. This will extend the
heater lifetime.
The actuation of the Limit 2 thermostat may indicate damage to the heater. If the situation repeats itself, contact the
vendor service department.
4.2. Shutting the heater down
Set the work mode switch to position '0' - burner off (Palnik wyłączony), the ventilator shall continue operating until the
exchanger cools down sufficiently, whereupon it will shut off automatically.
The ventilator may turn on again - this does not indicate of a flaw.
In order to shut down the entire heater, set the main switch to position '0'.
4.3. LIMIT 2 safety thermostat
When the air temperature exceeds 80 °C, the Limit thermostat shall shut down the burner, and later it will turn it on again
automatically. If the thermostat does not operate properly and if the air temperature rises to 100 °C, the main safety
thermostat Limit 2 shall switch the burner off. The thermostat diode on the electric cabinet shall light up (only 400 V
models). In such a case, wait for a few seconds for the fan to cool down the heat exchanger, and then press the
thermostat button located under the cover cap on the thermostat cabinet.
