INSTALLATION
Ventilation and suction ducts are fire classed, and
must therefore be insulated and fire classed as per
current regulations.
The air which is led off via the ducts has a temperature
of approx. 50-80°C if the installation is executed as per
Fig. 23 or 24. The air volume which is led off it approx.
150-200 m³/h.
Exhaust ducts Fig.23
To ensure that smoke and hot air from the oven do not
come into the room a ventilation duct must be fitted over
the oven exhaust duct.
The ventilation duct must under no circumstances be
connected directly to the oven exhaust ducts, if there
is no canopy installed in the oven.
There must always be some form of draught
interruption as shown in Fig.23b.
Exhaust hood Fig.24
If a hood is fitted over the entire oven it is not necessary
to fit separate exhaust ducts on the oven.
The hood should be approx. 0.5 metres larger than the
external contours of the oven to be able to trap smoke and
hot air.
Connection to ventilation duct.

Leave a 500 mm free space on the right-hand side of the
oven. This space is needed for access to the oven
distribution box during installation and service.
If the oven is fitted with built-in steam generator an
additional 200 mm wide space is needed between the
wall and the back of the oven.
This space is needed for taking out the steam generator
water nozzle for cleaning.
