4. Controller characteristics
•three-stage power adjustment for the stove 8-19-30 kW,
•preserving settings after blackout.
5. Safety aspects
The MTM 8-30 universal oil heater is powered by the alternating current network of 230V/50Hz. It is
equipped with three sensors, ensuring safe and economic operation of the device.
1. The bimetallic sensor, placed in the furnace chamber, reacts with short circuit of the contacts in the
thermostat when the temperature exceeds 40°C and with contact opening when the temperature drops below
35°C.
2. The bimetallic sensor is located near the downcast ventilator, with threshold temperature
of 100°C, opens the contacts when the said temperature is exceeded and causes switching of the stove in to the

emergency mode, cutting off inflow of fuel, thus securing the fan against overheating or melting
of its elements.
3. Microswitch - weight sensor located under the combustion chamber. Filling the pan causes
immediate switching into the emergency mode, cutting off the fuel inflow, securing against
leakage of the excess non-evaporated fuel outside the combustion chamber, eliminating the possibility of its
ignition
outside the device.
The connection of the stove controlling panel to other system components (sensors, pump, fan)
is factory-made. During normal use, due to operation safety, under no circumstances should there be any
interference in the covered and sealed part of the stove controller or duct integrity. Any action by an
unauthorised person may result in electrocution (230V AC, 50Hz) and burning.

7. Device installation
-familiarise with the local regulations,
-set the stove on a flat and hard ground,
-level the device,
-to provide optimal draught, install an at least 5-metre-long smooth, vertical stack pipe
resistant to high temperature (not aluminium), preferably
made of stainless steel,
-check the tightness of all connections, tighten them with insulating tape,
-make sure the elements inside the combustion chamber are properly mounted and the burner
is pushed to the end,
-check the network voltage (220-240V/50Hz) connecting the stove to power supply and changing the
position of switch 0/1,
-check if the switch lights up red when in position 1.
7a. Stack ducts installation
To ensure proper combustion, the stack system must be installed properly.
After the installation the following indications have to be followed:
-diameter of the exhaust fumes outlet from the device is 130 mm,
-recommended diameter of the stack pipe is 130 - 150 mm,
-minimal stack height with diameter of 150 mm is 5 metres,
-check the tightness of the stack component connections,
-wind should freely fan the stack outlet from all directions (the end of the stack pipe
should be above the rooftop level),
-wind should freely fan the stack outlet from all directions - the end of the stack pipe
should be above the rooftop level,
-if possible, all stack sections should be vertical - horizontal sections should be
avoided as well as stack pipe bends. If they are necessary (e.g. two bends if the pipe runs
through a wall or a window), the maximal bend angle cannot exceed 45°
and the minimal stack height should be increased to 6 meters.

CAUTION
When installing the exhaust discharge system it is recommended to avoid horizontal sections of the stack pipe.
In order to ensure free flow of gases, the angle of potential pipe bend should not exceed/be lower than 45°.
The stack outlet must be above the roof top, preferably by ca. 1 m.
The places where the stack penetrates the ceiling, walls or roof must be insulated in order to avoid fire hazard.
It is recommended to use a double-layered insulated stack pipe wherever contact is possible as well as outside
the building in order to ensure continuous draught and prevent condensation. Do not place any materials near
the stove, even non-flammable ones. Provide continuous air access, necessary for the proper combustion
process.

8. Description of device operation
8a. Control panel
The MTM 8-30 type universal oil stove controller is equipped with the power setting knob, network
switch and fuse socket.
Fig. 5. Vide of the front control module panel.
8b. The operation of the device is characterised by the following statuses:
• Stop
device ready for start-up
preliminary device operation stage
proper operation device operation
device switch-off
emergency switch-off
emergency switch-off
• Firing up
• Operation
• Damping
• Overheating
• Tank overflow
Heat generation occurs through the combustion of gas produced by the oil heated to high temperature. At the
moment of connecting it to the power network, the device is in the standby phase (Stop) - no heat is generated, the fan and
the pump do not operate.
Pressing the button marked as NETWORK in position 1 causes switching into readiness for firing up (see firing up in
point 9a). When the furnace has heated up to ca. 40°C, the oil feeding pump and downcast ventilator are switched on, the
red lamp of switch 0/1 is turned on.
Due to decreased oil demand by a non-heated furnace, after the start-up of the device it should operate with 19
kW power for at least 15 minutes. After ca. 15 minutes of operation, when the furnace pan is sufficiently heated up and is
able to evaporate a greater amount of oil, the power of the device can be switched to 30 kW or lower - 8 kW. During
maximum power operation, the amount of oil fed to the furnace is ca. 3 litres.
The heater is switched off by pressing the NETWORK button into position “0” on the control panel. This causes
switching off. The downcast ventilator operates until the furnace temperature falls below ca. 35°C (Damping). Having
reached temperature below 35°C, the stove comes back to the Stop phase.
The stove can be automatically switched off in the following cases:
-overheating of the combustion chamber,
-overflow.
The overflow status is generated by the bimetallic sensor located near the fan.
The contact opening signals that the threshold temperature value has been exceeded. The control system switches off the
pump feeding fuel, and the fan operates until the furnace temperature falls below 35°C. Having reached
temperature below 35°C, the stove comes back to the Stop phase.

In order to return to normal operation, wait until the stove has cooled down
(i.e. the fan has switched off and the chamber is cooled down) and press the button on the casing of the
bimetallic sensor (reset).
Clean the chamber pan, taking into account that the pan and deflector can still be hot due to the fact that
cast iron keeps temperature for a long time. Then the stove can be switched on according to point 9a.
The overflow signal is generated by the mechanical sensor located under the overflow tank.
The contact opening signals that the tank has overflowed and switches off the fuel feeding pump and the fan
keeps operating until the furnace temperature falls below 35°C. When this happens, the stove comes back
to the Stop phase.
In order to return to normal operation, wait until the stove has cooled down (i.e. the fan
has switched off and the chamber is cooled down). Drain the overflow tank, clean the furnace pan and the
combustion
chamber, taking into account that the pan and deflector can still be hot due to the fact that cast iron keeps
temperature for a long time. Then the stove can be switched on according to point 9a.
9. Heater operation
CAUTION!!!
DO NOT RE-FILL OIL IN THE FURNACE AND FIRE UP WHEN THE CHAMBER OR
FURNACE PAN ARE STILL HOT!!!
ALWAYS WAIT UNTIL THE FURNACE PLATE HAS FULLY COOLED DOWN. FAILURE TO
OBSERVE THE ABOVE MAY RESULT IN
UNCONTROLLED IGNITION OF OIL VAPOURS AND BURNS!!!
9a. Starting the device.
-if needed, remove water from the fuel tank and fill it with oil (e.g. used oil),
-check whether the overflow protection mechanism works properly by
pushing the bowl lever down and letting it come back to its original position, which
will be confirmed by the characteristic “click” sound,
-check whether the device burner is maximally pushed to the housing of the device (if not,
push until resistance),
-insert the power plug in the power socket (230V / 50Hz),
-draw the top part of the heater housing aside and remove the combustion chamber cover.
Then, take the cylinder and deflector out (if necessary, thoroughly clean the combustion bowl, the base
which it is placed on and the entire combustion chamber along with the sleeve and deflector),
-check whether the furnace bowl is cool and clean and pour ca. 250 ml of fuel or diesel
oil,
-mount the ring and cylinder,
-fire the oil up using paper crumbled into a ball - set it on fire and throw onto the furnace bowl,
-replace the combustion chamber cover and close the top housing part of the heater,
-press the button marked as NETWORK into position 1 and turn the power setting knob into 19 kW
or 19 kW, depending on the required heat amount,
-after about 10-15 minutes, depending on the room temperature, the fuel pump and the fan
are switched on and the red lamp of the 0/1 button is on. The stove has to operate with this power
for at least 15 minutes. After ca. 15 minutes of operation, when the furnace pan is sufficiently heated up
and is able to evaporate a greater amount of oil, the power of the device can be switched to 30 kW or
decreased to 8 kW.

9b. Switching the device off
In order to switch the device off and complete the heating process, turn the power setting knob
on the control panel into the fan position and switch the button marked as MAINS to 0, causing the lamp
to switch off. The pumps will stop feeding fuel to the combustion pan and the ventilator will operation until the
stove has cooled down. The damping process depends on the room temperature and degree of heating
of the combustion chamber and it can vary from 20 to 40 minutes.
DO NOT disconnect the device from power supply when the fan is operating! Wait until the stove has cooled
down. The stove is switched off automatically. Remember that after the stove is switched off, the cast iron pan
keeps higher temperature for some time (depending on the ambient temperature) and the stove cannot be
fired up again until the pan has fully cooled down! DO NOT throw the hot* pan on the snow, do not pour cold
water on it in order to cool it down - a hot pan, due to the great temperature difference, can break and will be
unfit for use!!!
9c. Maintenance
The heater does not require many maintenance procedures. Observance of the manufacturer’s
recommendations in this scope will ensure failure-free and safe operation of the device:
-clean the furnace pan every day as well as other elements of the combustion chamber (cylinder,
deflector and cover),
-check patency of the overflow tube (tube in the bottom part of the combustion chamber, directly
above the overflow pan), clean if needed,
-at least once a week clean the combustion chamber base (element under the furnace pan),
-check if the openings of the air inlet in the upper and bottom part of the combustion chamber are not
covered,
-at least once a week clean the fuel feeding tube (burner), maximal operating time
without furnace pan cleaning is ca. 7-15 hours (depending on the oil used for combustion),
-clean the fuel tank and oil pump filter during the heating season,
-if the furnace is switched off for a longer period of time, the combustion chamber and day
tank must be thoroughly cleaned and then secured against corrosion with a thin layer of oil.
