WARNING:
To use the capacity of the device optimally and to ensure its
failure-free functioning, please read carefully this operating
manual.
This equipment is not intended for use by persons (including
children) with a limited physical, sensual and psychical
abilities or by persons who are not experienced or familiar
with the equipment unless it is done under the supervision or
in accordance with the operating manual of the equipment
delivered by persons responsible for their safety. Pay
attention to children as they should not play with the
equipment.
If an undetachable power cable is damaged, it should be
replaced at the manufacturer or at the specialist repair works
or by a qualified person in order to avoid hazard.

INSTALLATION

Become familiar with the local regulations.
Place the furnace on a flat concrete ground.
Install the heat distributor with a conduit at the top of
the WA 33 B furnace.
Take all the furnace parts packed inside the
incineration chamber out.
Level the furnace. In order to check whether the
furnace is levelled, place the combustion dish (22) in
the bottom part of the incineration chamber and pour
out a small amount of fuel oil on it. The oil should be
spilled exactly in the middle of the plate.
Mount the air regulator on the pipe coming out of the
incineration chamber, in order to ensure a stable
draught during the use of the furnace.
In order to ensure optimal draught, install at east a 5-
metre long vertical chimney pipe resistant to high
temperature (not made of aluminium).
While installing the exhaust fume discharge system, it
is recommended to avoid the horizontal sections of the
chimney pipe. In order to ensure the free outflow of
gases, the angle of the possible pipe bend should not
be greater than maximum 45º.
Chimney outlet must be higher than the top of the roof.
WARNING:
The places at which the chimney pipe passes through the
ceiling, walls or the roof, must be insulated in order to avoid
the fire hazard. It is recommended to use the double-wall
insulated chimney pipe at all places where there is a
possibility of a contact by touch and outside the building in
order to ensure the permanent good run and prevent the
condensation. The air heater may not be connected to the
joint exhaust fume discharge system.
Check the tightness of all connections, if necessary,
tighten them with the insulation tape.
Make sure that the combustion dish is placed centrally
in the incineration chamber
Place the chamber disk (20) inside the combustion
chamber with the inset in the middle of the ring to the
top and mount the chamber pipe on it (17).
Check the mains voltage and connect the furnace to
power supply. Neither the fan nor the pump should be
switched on as the furnace is not switched on yet and
no heat has been produced.
The device is equipped with a pump performance control
thermostat (T ) and an overheating thermostat (T
V
WARNING:
Do not place any materials nearby the furnace, even the ones
that are not inflammable. Ensure permanent access of air
necessary for the proper incineration process.
Do not light the hot burner plate again.
Always wait until the burner plate is completely cooled off.
For the correct incineration process, ensure access of the
appropriate quantity of air
OPERATION OF THE FURNACE
The furnace may be operated with the use of various
types of oils (diesel oil, fuel oil, biodiesel oil, pure and
used engine oil, gear oil, hydraulic oil, plant oil etc.) You
must not apply transformer oils and nitro substances.
Two switches (49) and (67), a control lamp (68),
informing about the operation of the pump and the pump
motor fuse (72) are located on the control panel. The
switch (49) fulfils the function of the main power supply
switch. The switch (67) serves the purpose of changing
the heating efficiency and switching off the pump. In
position „I" the furnace operates with lower efficiency and
in position "II" with greater efficiency.
The furnace has no protection from the extinguishment
of the flame at this moment; the pump will not stop
functioning and the oil may overflow. The overflow
protection will switch off the pump (the control lamp will
be switched off), but the fan (7) will still function. THE
FURNACE MUST COOL OFF, then the overflow
protection and the place under the burner plate must be
cleaned.
WARNING:
During the operation of the air heater, the temperature of
respective parts is high, therefore it is necessary to maintain all
the necessary precautions.
RECOMMENDATION:
Use switch (49) during problems with starting the
furnace. In the initial stage of starting the furnace,
leave switch (49) for 20-30 minutes in position "0",
and then continue the activities according to the
manual for starting the furnace.
Pump motor (52) drives the pump which is located
inside the tank and overflows the oil through the fuel
supply set (61) onto the combustion dish (22).
After the furnace is lighted, it should operate with a
smaller efficiency for about 20 minutes in order to
produce the appropriate temperature for operation
with higher efficiency.
WARNING:
Do not pull out the plug from the electrical socket, before the
motor cools off completely.
