Danger of death! Gases are generated during the
storage of slurry which remain partly dissolved in
the liquid. If the slurry is strongly agitated during
mixing and purging, poisonous, explosive gases
such as hydrogen sulphide and methane are released. If an ignition source is present, the released
gas can explode.
To avoid damage during operation, please observe
the following:
–Switch off the heater before mixing and purging
the slurry.
–Close the slide valves when storing slurry outside.
–The fan for the air supply must not be part of a
closed pipe system.
–The space to be heated must be adequately
ventilated.
For mechanical extraction equipment: at least
10 m3/h of air per installed capacity.
In the case of natural ventilation, the structure
must have two apertures with a free opening
area of 60 x B in cm2. “B” is the installed capacity in kW. Replacement of the full air volume per
hour is thus ensured.
–In the case of natural ventilation, the maximum
allowable total capacity of the heater is 1 kW
per 20 m3 of volume.
–Respect the safety distance of the heater to
inflammable materials, see “Installation position”.
–Consult your fire insurance provider and/or local
fire protection engineer to assess the foreseeable, general risk of fire.
–For cleaning, care and maintenance, note the
applicable national regulations and directives.
–No condensation permitted. Check the ambient
temperature, see page 17 (Technical data).

Adjusting the switch-on delay tE
▷▷ If multiple heaters switch on at the same time,
there can be a gas and/or power shortage on individual devices. To avoid this happening, adjust
the switch-on delay tE using the potentiometer

or other parts such as the spark plug or rubber
seals can be displaced. Avoid direct contact.

Cleaning
CAUTION
To ensure that no damage occurs during operation
and cleaning, please observe the following instructions. Otherwise, injuries or damage to the device
may occur and/or the function of the device may
be impaired, and the manufacturer’s warranty will
be cancelled.
–Sharp-edged metal sheets. Always wear protective gloves.
–After cleaning, check that the components on
and in the heater are in good condition. The
device may only be restarted if all safety devices
have been installed and the safety functions
have been checked.
–Clean the heater once a year when used in
horticulture and at regular intervals as well as
after each fattening period when used in agriculture, as described below. Inadequate or
irregular cleaning can cause damage to the
device or lead to fire damage. For example, dirt
particles can catch fire and can be blown out
of the device.
▷▷ Do not spray water or chemical cleaning agents
directly into the space between the fan shaft/
impeller wheel and motor and do not clean with
high-pressure cleaners.
1Switch off the burner control unit BCU.
2 Disconnect the system from the electrical power
supply. The mains plug may only be pulled out
once the device has been switched off and postcooling is complete.
3Shut off the gas supply.
▷▷ If the burner control unit and the gas combination control are not equipped with protective
caps, we recommend cleaning the heater with
compressed air or a damp cloth only.
GB-8
▷▷ Chemical cleaning agents, disinfectants and/or
pesticides contain corrosive substances which
can even corrode stainless steel. Always rinse
the devices with water after cleaning using such
agents to remove any residue of these agents
from the surface.
▷▷ Loosen the screw connection on the grille just
enough to be able to move the screw connection to the side.

WARNING
To avoid harm to persons and animals or damage
to the heater, please observe the following:
–Electric shocks can be fatal! Before working
on possible live components, ensure the unit
is disconnected from the power supply.
–Fault-clearance must only be undertaken by
authorized trained personnel!
–Repairs to components, e.g. the burner control
unit BCU or the combination control CG, may
only be carried out by the manufacturer. Otherwise, the guarantee will be cancelled. Unauthorized repairs or incorrect electrical connections,
e.g. the connection of power to outputs, can
cause gas valves to open and the burner control
unit to become defective. In this case, fail-safe
operation can no longer be guaranteed.
–(Remote) resets may only be conducted by authorized personnel with continuous monitoring
of the devices concerned.

LED on the burner control unit lights up. Then,
the fault is indicated by a combination of flashing
yellow LEDs which are numbered from 1 to 5.
▷▷ Faults may be cleared only using the remedies
described below.
1Press the reset button on the BCU to reset it.
The unit then reverts to the last operating mode
selected.
▷▷ Faults marked with an * are warnings. Provided
that a restart has been programmed, they are
no longer displayed if the cause of the fault has
been remedied. It is not necessary to press the
reset button when these messages are displayed.
2 If the burner control unit does not respond even
though all faults have been remedied, remove
the unit and return it to the supplier.

!On burner start-up, the BCU has not detected
a flame during the safety time. In the parameter
“Number of start-up attempts”, it is possible to
program up to three start-up attempts. If one of
the further start-up attempts is successful, fault
signalling stops automatically once the postpurge time has elapsed.
• Ignition is not working properly.
Clean the spark electrode and check for correct
distance, see page 12 (Maintenance).
Check the connection of the ignition cables for
damage or moisture.
The spark plug must be fitted correctly.
Check the ignition spark optically and acoustically
from the fan side during the 4-second ignition
time.
• Poor flame signal due to incorrect burner adjustment. Readjust gas pressure pG, see page 6
(Adjusting the heater).
• Poor flame signal due to dirty/badly connected
flame rod.
Clean the flame rod and check for correct distance, see page 12 (Maintenance).
Check the cable connection, cable and plug for
damage or moisture. The plug must be fitted
correctly.
Check the yellow and green burner ground cable
for corrosion and to ensure it is firmly connected.
• Air in the gas pipe. Vent the gas pipe.
• Valves do not open. Remove the valve plug on
the combination control CG and measure the
voltage between L1 and N during the safety time.
If the voltage is not adequate, first replace the
CG and return it to the supplier.
Attention! Only commission the new BCU once
the short-circuit or fault on the valve output of
the CG has been remedied. Otherwise, the new
BCU will be damaged.
• If the fault continues to be signalled, there may
be a short-circuit on the valve output. Return
the burner control unit to the manufacturer for
inspection.
• Short-circuit on ignition output. Replace fine-wire
fuse F2: 3.15 A (slow-acting, H) and check the
safety function, see page 14 (Checking the
safety functions and burner operation).

To ensure that no damage occurs during operation
and maintenance, please observe the following
instructions. Otherwise, injuries or damage to the
device may occur and/or the function of the device
may be impaired. The supplier/manufacturer cannot
accept liability for damage resulting thereof.
–Have the heater cleaned at least once a year
by qualified maintenance personnel.
–Have the safety functions checked at least once
a year by qualified maintenance personnel, see
page 14 (Checking the safety functions and
burner operation).
–Sharp-edged metal sheets. Always wear protective gloves.
–After cleaning or repair work, check that the
components on and in the heater are in good
condition. The device may only be restarted
if all safety devices have been installed and
the safety functions have been checked, see
page 14 (Checking the safety functions and
burner operation).
