Excerpt from the Heating Appliances

Ordinance
The Firing Directive - FeuV (§4 establishing
fireplaces...) states:
... The operational safety of room air depend-
ant heating appliances may not be adversely
affected by the operation of systems that
take in room air such as ventilation or hot air
heating systems, extractor hoods, convection
dryers, etc.
This is deemed to be fulfilled if:
• the simultaneous operation of heating
appliances and the systems that take in
room air is prevented by safety equipment,
• exhaust gas venting is monitored by
special safety equipment,
• the exhaust of the heating appliances
are vented through the systems that take
in room air, or
• it has been ensured from a system
technology point of view that no
dangerous negative pressure situation
is created during the operation of the
heating appliances.
Devices operated by circulating air are not af-
fected by the Heating Appliances Ordinance.

Potential risks

Due to the that went into effect in 1995
Ordinance on Thermal Insulation for New
Buildings and the nearly hermetically sealed
windows and doors introduced by this, no
"permanent ventilation" takes place.
a) Devices used in exhaust air mode draw the
necessary room air from the living areas (e.g.
extractor hoods in kitchens). Without suffi-
cient supply air, negative pressure is created.
The heating appliance does not receive suf-
ficient combustion air, which can adversely
affect combustion. Poisonous combustion
gases, including poisonous carbon monox-
ide, can be drawn from the chimney or flue
into the living areas
life-threatening!
To avoid the risk of carbon monoxide poison-
ing, always ensure sufficient fresh air
