Please read the entire User Guide before lighting the fire for the first time. In partic-
ular, please note the safety precautions in this manual.
Installation must be carried out by an authorized stove-fitter, because safety and ef-
ficiency of the system depend mostly on proper installation of the product. All valid
stove fitting rules and regulations of building law must be observed and followed.
This fireplace is subject to the provisions of 1. BlmSchV.
Necessary national and European standards and local regulations must be ob-
served.
Old devices contain recyclable materials. Please follow the applicable national regu-
lations for disposal.
Please follow the relevant regulations of your country. In case of doubt, check the
valid conditions for the operation of fireplaces in your local area.
Subject to technical changes!
Please keep the User Guide for future reference!

1 CONTROLLER OPERATION
1.1 OVERVIEW OF USER INTERFACE
Your stove equipped with the electronic combustion control system EAS (ger. Elek-
tronische Abbrandsteuerung) is even more comfortable to use. No technical knowl-
edge is required to operate the system. The EAS control system optimizes the com-
bustion process and its quality, which means that the emissions are reduced to a
possible maximum.
A switching output is available for additional switching functions, as the automatic
switching of combustion gas flow (heat-up flap) or deactivation of a kitchen hood.
The relevant additional function has been selected and set up during commission-
ing by your stove building contractor.
In the following picture, you can see the EAS controller with the individual displays
and controls.
The main display function is to provide information about the current status of the
system. It shows the current temperatures and additional information about the sys-
tem. In addition, error messages are displayed in case of malfunction.
Always visible (except
Standby mode) Displayed if necessary

Hint symbols (1)
The hint symbols make the current EAS settings or faulty operation visible at first
glance.
Fire starting error
The fire starting temperature (default: 100°C) was not reached in a giv-
en time (default: 15 minutes).
- Start the fire again
- Use appropriate fire starting aids, like Fidibus sticks; do not use fire
starting aids in form of fluids!
- Use small pieces of wood for starting fire.
Combustion error
The threshold temperature was not reached in a given time.
-> Use only dry firewood in a prescribed amount. Improper fuels or
waste must not be burned in a fireplace.
Stove door
The stove door is open for too long.
-> Close the stove door

10 Operating Instructions (1.14) © 2017 Brunner GmbH
Stove hot
The combustion chamber temperature is above the allowed maximum
for the stove or fireplace type.
- Use not more than the maximum amount of fuel.
- Insert a ‘heating break’ between the reheating intervals. The efficien-
cy of the heating installation is unfavorable.
S+
The prolonged combustion mode is active.
This setting can be useful for avoiding/reducing the charcoal build-up
during combustion.
Eco off
The messages for heating up and heating errors are deactivated.
Small numeric display (2)
The small numeric display is used to show the error messages. Each error
is indicated by a short beeping sound. The sound is repeated up to 10 times
and can be switched off by pressing the ENTER button.

If an error is shown here, the stove builder has to be informed and the heat-
ing installation should be controlled manually. You will find a description of
this procedure in the chapter "Heating with manually controlled combustion
air supply".
If the message "FBAT" or "LBAT" appears, the battery must be changed im-
mediately in a correct way.
Without correctly inserted battery the emergency function cannot
be ensured.
Big numeric display (3) with the relevant unit of measurement (8)
The big numeric display shows the current combustion chamber temperature
or a selected parameter value.
Combustion cycle graphic (4)
A combustion cycle graphic is shown during operation, including the current
combustion stage indication. The current combustion stage is indicated in
form of a bar graph.
In Standby mode, this part of display is empty.
