3 Terms and definitions
In the application of this standard the following terms apply:
3.1
kitchen ventilation hood
the part of a mechanical ventilation system enclosing a space for kitchens for supply air and exhaust air, can
be equipped with integrated ceiling in accordance with prEN 16282-3
NOTE The lighting device is an integral part.
The purpose of kitchen hoods is to remove the heat, smoke, effluent, and other contaminants. The thermal plume from
appliances takes up the contaminants that are released during the cooking process. Room air replaces the void created by
the plume. If convective heat is not removed directly above the cooking equipment, impurities will spread throughout the
kitchen, leaving discoloured ceiling tiles and greasy countertops and floors. Therefore, contaminants from stationary local
sources within the space should be controlled by collection and removal as close to the source as is practical.

Appliances contribute most of the heat in commercial kitchens. When appliances are installed under an effective hood,
only the radiant heat contributes to the HVAC load in the space. Conversely, if the hood is not providing sufficient C&C
(Capture & Containment), convective and latent heat are ‘spilling’ into the kitchen thereby increasing both humidify and
temperature.
Capture efficiency is the ability of the kitchen hood to provide sufficient C&C at minimum exhaust flow rate. The remainder
of this chapter discusses the evolution and development of kitchen ventilation testing and their impact on system design.

5.1 General remarks
Insofar as nothing to the contrary is stipulated, the requirements are checked by inspection and/or measuring.
Air containing fumes emitted from kitchens such as, for example, warm kitchens, portioning rooms, food
distribution areas, serving area (also in dining room), crockery and washing rooms shall be treated by means
of an effective fume separation before it enters the air ducts.
In commercial kitchens, hoods complying with prEN 16282-2 or ceilings complying with prEN 16282-3 are to
be employed for ventilation.
Hoods and their components (lightings, outlets, room ceilings, etc.) shall be arranged over the entire area of
the rooms in question. For room ceilings materials shall be used according to Table 2.
It is recommended, that a secure sensor port which can be easily accessed once installed should be provided
to measurethe differential pressure in the outgoing air area. The default dimension for this port is either an
external diameter of 4 mm or a round sensor aperture with a diameter of 12 mm. present

Figure 1 — Hood dimensions
5.2.2 Suspension height
During fitting, the fitting instructions are to be observed for any fitting mounts required.
Suspension height
The recommended suspension height of installation for a hood (lower edge of the hood, see figure 1 and 2) is
2.0 m above floor level. The minimum height shall be 2.0 m and the maximum shall be 2.5 m.
Installation heights deviating from this are possible for special function hoods (grill hood, bar hood/counter
hood).The height of the canopy is often governed primarily by the ceiling height. The top should project into
the ceiling by a minimum of 0.3 m to allow the false ceiling trim to be attached.
5.2.3 Hood dimension
Hood length/width shall be configured so that an overhang of at least 0.3 m extending beyond the outer edge
of the cooking equipment is ensured. For equipment with front doors (ovens, hot air steamers) an overhang of
at least 0.6 m shall be observed. Installation lengths/heights deviating from this are possible for special
function hoods (grill hood, bar hood/counter hood).

oSIST prEN 16282-2:2011
prEN 16282-2:2011 (E)
If a suspension height of more than 2.0 m is taken as a basis, the configuration of the hood length and hood
width shall take into account that these dimensions need to be increased to cater for the lateral opening angle
(see Fig 1) of 15°.
5.2.4 Hood height/collection area
A minimum height of 0.4 m shall be observed.
The volume of the collection area shall be as large as the airflow volume to be extracted per second. For
hoods that are arranged over equipment that generates a high quantity of fumes (kettle, fryers etc) the hood
height and the collection area are to match the equipment. This does not apply to special function hoods (grill
hood, bar hood/counter hood).
5.2.5 Infillpanel
The height of the canopy is often governed primarily by the ceiling height. The underside of the canopy should
be located between 2.0 m and 2.1 m above the finished floor level, the top should project into the ceiling by a
minimum of 0.25 m to allow the false ceiling trim to be attached (figure 2).
Access panel should be opened without a tool.

The grill hood is permitted to be suspended at a maximum 1.8 m from the upper edge of the hood to the
finished floor.
The grill hoods are not permitted to be suspended at heights that exceed 1.2 m from the lower edge of the
collection area to the finished floor and are to have a rear wall as well as a two-sided wall up to the upper
edge of the equipment unit.
The distance between the lowest edge of the separator and the top of the cooking surface should be 0.45 m
minimum. This is to avoid the risk of excessive temperatures or fire in the separator which could cause the
