The exactractor hood can be used in exhaust air 
mode. 
Always mount the extractor over the centre of the 
hob. 
Minimum distance between electric hob and 
bottom edge of the extractor hood: 550mm. 
 
The applicable regulations of the power supply 
company and compliance of local and national 
building regulations must be observed when 
installing air extractor (overhead and table top 
downdraught) in permanent dwellings. 
 
The extractor hood must not be installed over a 
solid  fuel cooker – a potential fire hazard (e.g. 
flying sparks) unless the cooker features a closed 
non removable cover and all national regulations 
are observed. 
This limitation is not valid if you use gas cooking 
top and gas cooker. 
The smaller the gap between the extractor hood 
and hotplates, the greater the likelihood that 
droplets will form on the underside of the extractor 
hood. 
 

Additional information concerning gas cookers: 

When installing gas hotplates, comply with the 
relevant national statutory regulations (e.g. in 
Germany – Technische Regeln Gasinstallation 
TRGI). 
Always comply with the currently valid regulations 
and installation instructions supplied by gas 
appliance manufacturer. 
Only one side of the extractor hood may be 
installed next to a high-sided unit or high wall. Gap 
at least 50 mm. 
Minimum distance on gas hotplates between the 
upper edge of the trivet and the lower edge of the 
extractor hood: 650 mm Fig.2

Prior to installation 

Exhaust air mode 

The exhaust air is discharged upwards through a 
ventilation shaft or directly through the outside wall 
into the open. 
Exhaust air should neither be directed into a 
smoke or exhaust flue that is currently used for 
other purposes, nor into a shaft that is used for 
ventilation rooms in which stoves or fireplaces are 
also located. 

Exhaust air may be discharged in accordance 
with  official and statutory regulations only (e.g. 
national builing regulations) 

Local authority regulations must be observed 
when discharging air into smoke or exhaust air 
flues that are not otherwise in use. 

 
When the extractor hood is operated in 
exhaust-air mode simultaneously with a 
different burner which also makes use of the 
same chimney (

such as gas, oil or coal –fired 

heaters, continuous-flow heaters, hot water 
boilers) care must be taken 

to ensure that there 

is adequate supply of fresh air

 which will be 

needed by the burner for combustion. 
Safe operation is possible provided that the 
underpressure in the room where the burner is 
installed does not exceed 4 Pa (0,04mbar)  
This can ben achieved if combustion air can flow 
through non-lockable openings, e.g. in doors 
windows and via the air-intake/exhaust-air wall box 
or by the other technical measures, such as 
reciprocal interlocking, etc. 

 
If the air intake is inadeguate, there is a risk of 
poisoning from combustion gases which are 
drawn back into the room.
