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"... -
Page 7: Brula Neo Functional Description
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. -
Page 8: Safety Instructions
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. -
Page 9: Design And Installation
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. - Page 10 To unfasten the plug connection, press down on the stop hook and pull the connector out of its bushing backwards.

Page 15: Installation Of The Cable Housing
If the relay outputs 2 and 3 are connected to line voltage, cable housings must also be fitted to them. These can be ordered quoting Item Number 1047657. For further instructions, please refer to chapter 10. BRULA NEO service instructions Dated 03/18 Page 15 of 52... -
Page 16: Connection Of The Motor
The fireplace must never be operated like this! The BRULA NEO is equipped with an external throttle valve. The electrical motor connection is on the THROTTLE VALVE bushing. These external throttle flaps have an integrated spring return that releases the entire cross section in the event of a power failure. -
Page 17: Motor Cable
If the motor cable is too short, it can be extended with a copper wire measuring 3 x 0.75 mm² to a length of about 10 metres. For other lengths, please consult BRULA. Ensure that the wires are connected up correctly. BRULA NEO service instructions... -
