5.2 Adjacent systems
Dealing with the discharged air
During operation, the combi oven generates heat and moisture, which mainly escape upwards into the
surrounding air as hot vapour from the air vent(s). It is not permitted to connect air ventilation pipes
directly to an air vent of the combi oven.
The manufacturer recommends using a fume extractor hood or ceiling-fitted ventilation equipment to
extract the discharged air from the room in which the combi oven is operating.
In order to avoid the risk of fire or other damage to the building such as corrosion, mould growth
and/or reduced stability, there must be a sufficiently large distance between the top of the appliance
and the ceiling. This distance depends on the following factors:
■
For guidance on the minimum vertical clearance, see 'Requirements for the installation location' on
page 48.
■
Type of air-vent system
■
the nature of the ceiling in the installation location
It is a fundamental requirement that the combi oven is always set up, installed and operated in accord‐
ance with national and local standards and regulations (in the latest version).
In addition, please observe the following regulations:
■
VDI Directive 2052 "Ventilation equipment for kitchens"
■
Guidance from the local building authority for fume extraction systems.
Dealing with exhaust gases for gas appliances
Exhaust gases at a temperature of up to 500 °C escape from the exhaust outlet(s) on the top of the
combi oven into the surrounding air. It is not permitted to connect pipes directly to an exhaust outlet of
the combi oven as a way of removing the exhaust gases.
It is mandatory to use a ventilation system with a safety cutout for evacuating the exhaust gas.
The combi oven has an exhaust gas extraction system that complies with standard EN 203 type A3 /
B23.
In order to avoid the risk of fire, there must be no flammable materials above the appliance and there
must be a sufficiently large distance between the top of the appliance and the ceiling. This distance
depends on the following factors:
■
For guidance on the minimum vertical clearance, see 'Requirements for the installation location' on
page 48
■
the type of air ventilation system and exhaust gas extraction system
■
the nature of the ceiling in the installation location
It is a fundamental requirement that the combi oven is always set up, installed and operated in accord‐
ance with national and local standards and regulations (in the latest version).
In addition, please observe the following regulations:
■
VDI Directive 2052 "Ventilation equipment for kitchens"
■
