1.An under-pressure monitoring system switches air-drawing systems (e.g. room ventilation, etc.) off when the under-pressure in the
installation room exceeds a certain limit. This prevents a reversal of the combustion gas flow in the chimney and thus smoke from being
sucked back into the installation room.
2.A window-tilting switch prevents major air-drawing systems (e.g. 3 or 4) from operating with the window closed. A drive systems tilts the
window open when air-drawing systems (e.g. 3 or 4) are in operation. This prevents a reversal of the combustion gas flow in the chimney
and thus smoke from being sucked back into the installation room.
The following applies if the appliance is to be operated in conjunction with other air-
drawing systems:
❒ The possibility of simultaneous operation of appliance and other air-drawing
systems (e.g. room ventilation) must be clarified in advance with the responsible
chimney sweep
❒ Observe the chimney sweep's assessment criteria
➥ These apply until an appropriate regulation has been published
❒ Only use approved safety equipment (e.g. under-pressure monitoring system and/
or window-tilting switch with DIBt certification [DE])
❒ Make sure that the combustion air supply line and the connecting piece are
properly sealed at the chimney
