1 General information
You have decided in favour of a BRULA fireplace insert accessory - thank you
for your confidence in our company.
These installation and service instructions provide details on the installation and
start-up of the combustion control system.
Details on operation of the combustion control can be found in the BRULA NEO
operating manual
Important information is printed in bold. Important information and safety
instructions are printed in red and bold - always comply with these points.
Before using the appliance, please read the entire operating manual.
The combustion control system is pre-set to the nominal thermal output of the
delivered fireplace. Information concerning the nominal heat output and the
wood feed quantity can be found in the operating manual of the fireplace.
1.1. Information on installation
Please consult your district master chimney sweep before assembling and
installing your fireplace. He will advise you on building regulations, will check
the suitability of your chimney, will commission your fireplace and will issue the
operating licence for your fireplace.
When installing and operating the fireplace insert and connecting it to the
chimney, make sure that you comply with the national and European standards,
the country-specific and local directives and regulations as well as the fire
regulations for your state (in Germany only) and the Technical Rules of the
Stove and Hot Air Heating System Trade (TROL).
All work on the electrical installation may only be performed by an authorised
specialist company. All equipment must be switched off at the main switch
before performing work on it.

1.4. Accessories
If needed, all conduits can be extended using normal copper cable, but this
does apply to the cable on the flue gas temperature sensor. Here, a
special compensating line MUST be used.
•5m flue gas sensor extension cable (Item No. 1013221)
•10m extension cable for flue gas sensor (Item No. 1013222)
With appliances that circulate water, if the circulating pump is to be controlled
by the BRULA NEO, at least two or ideally 3 PT 1000 sensors should be ordered
at the same time. This is the only way of ensuring that the "Differential
temperature" function and control of the circulating pump can be implemented
together with the BRULA NEO.
•Temperature sensor PT1000 (Item No.. 1013765)
Length 3 metres, incl. immersion sleeve with a G1/2" external thread
•Plug housing for the pump cable, for additional insulation (Item No.
1047657)
If the control system housing of the NEO is to be protected in a special manner,
a dust protection box measuring 210 x 160 x 80 mm can be obtained in which
the control system can be installed. ATTENTION: The cable housings (see 3.4)
must be removed, otherwise the control system will not fit inside.
•Dust protection box for BRULA NEO (Item No. 1013792)

1.5. BRULA NEO functional description
The basic configuration of the BRULA NEO combustion control system
consists of the control unit, the display, a flue gas temperature sensor and a
motorised throttle valve for the combustion air. The control is only suitable for
fireplaces that burn split logs.
At the start of combustion, the BRULA NEO MUST be activated by
pressing the screen so that the throttle valve opens. The control works
without a door contact switch and detects opening of the door during operation
via a drop in temperature on the flue gas sensor, i.e., automatically. After
closing the door, the control switches, after a short holding time, back to
controlled operation.
Depending on the prevailing flue gas temperature, the control system adjusts
the throttle valve using the motor until the correct quantity of combustion air is
directed into the appliance. The time for adding fuel is displayed with a visual
as well as an audible signal.
The control system remains active until the flue gas temperature has dropped
to about 50°C and then it returns to Standby mode.
In the event of a power failure, the throttle valve automatically moves into a
position in which the fireplace can continue to be operated. Until power is
restored, or until the fire is extinguished, no further interventions or measures
are required.

2 Safety instructions
•At the start of combustion, the BRULA NEO MUST be activated by
pressing the screen so that the throttle valve opens. A fire may only be
ignited if the throttle valve (air slider) is at 100
•The BRULA NEO combustion control may only be used in combination with
a wood-fired fireplace.
•Only fireplaces which are ordered with this combustion control system and
that are appropriately prepared from the factory can be combined with the
BRULA NEO.
•The combustion control system cannot be retrofitted!
•The maximum ambient temperature for the electrical components is 50°C.
Measures must be taken by the customer to ensure that this temperature
is not exceeded.
•The total electrical installation of the individual components may only be
conducted by an authorised specialist company.
•All electrical installations are to be carried out as per the VDE regulations
(e.g. VDE 0105, VDE 0116, VDE 0100, etc.) and the technical connection
conditions of the local power company.
•All equipment must be switched off at the main switch before performing
work on it.
•The cables must be laid so as to allow maintenance work to be performed
and the individual components of the BRULA NEO to be replaced without
any problems.
•Building moisture and condensation are to be avoided as these can result in
corrosion and failure of the electrical components.
•The connecting cable of the flue gas temperature sensor can only be
extended with a special compensation cable!
•The specified factory settings which are required for the safe operation of
the combustion control may not be changed.
•The installed wires on the fireplace insert must not be pulled. Outside the
fireplace insert, these must be installed so that no tensile forces and no
compression, chafing or shearing points are created.

3 Design and installation
The design of the cladding must be such so as to enable access to all the
installed components at all times. This concerns the exhaust gas temperature
sensor, the connections, the motor and sensor wires and the control.
The control system should ideally be positioned behind an air grille in the stove's
cold area or in an adjacent room.
It is recommended to secure the socket to the BRULA NEO separately or with
a switch (on site). As a result, the system can be easily switched off in the
summer or for maintenance purposes.
The maximum ambient temperature at the installation location of the
control system must not exceed 50°C!
3.1. Installation and connection of the display
The installation site must be selected so that the maximum permissible
ambient temperature of 50°C is not exceeded and that this component is not
exposed to direct heat radiation when the fire is lit.
For the display cable, an empty tube is preferred with an internal diameter of
at least 18 mm, long enough to reach as far as the wall socket provided.
Break-throughs are laser-cut into the top, bottom and back of the wall socket.

The minimum dimension for the break-through in the wall is (W x H x D):
139 x 82 x 31 mm.
The wall socket must be installed absolutely horizontally in the wall so that the
front edge of the socket is at precisely the same level as the wall coating that
is installed subsequently. Only then will the installed display be flush with the
wall, without any gaps.
If the socket is not plastered in absolutely horizontally or too deep, it is
possible to adjust the position and installation depth of the display. There are
adjustable retaining tabs to the left and right of the wall socket, these are lined
with M4 washers. If the side parts of the socket are positioned too far inwards,
the washers must be removed and the tabs should be screwed on directly.
Initially on one side only and if necessary on both sides.
When inserting the display, the outer glass surface should never be
pressed on. Only ever press on the 4 corners of the actual screen in
order to avoid breaking the glass.
Once the socket has been plastered in and adjusted, the cable is inserted into
the back of the display. Ensure that the stop hooks on the connector click into
place, locking the connector in position. The cable must be routed without any
tensile forces, protected against shearing, crushing and chafing points.
To unfasten the plug connection, press down on the stop hook and pull the
connector out of its bushing backwards.
