Installation Premises; Discharge Of Flue Gases - EF HB-AG290VGB-A User Manual

Installation premises

For proper operation of a gas appliance, the air necessary for the combustion of the
gas must be able to flow into the room naturally. The air must flow into the room
directly through openings in the outside walls. These openings must have an
3
unobstructed cross-section of no less than 2m /hfor each kw of power(see total power
in kw on the appliance nameplate).
This opening must be constructed so that it will not be
obstructed from indoors or outdoor and placed close to the
floor, preferably on the side opposite to that on which the
flue gases are discharged. If it is not feasible to provide
these openings in the room where the appliance is installed.
The necessary air may be taken from an adjacent room,
provided that:
·this room is not a bedroom or a hazardous environment
area;
·this room is not in a vacuum;
·the ventilation between the room where the appliance is
installed and the adjacent room is guaranteed by permanent
openings.

Discharge of flue gases

Gas cooking appliances must discharge their flue gases
through hoods connected directly to flues or the outdoors.
If it is not possible to install the hood ( fig. B) an electric
fan must be installed on the outside wall or the window of
the room, provided it is possible for the ventilation opening
to be increased in proportion to the delivery rate of the fan
(fig. C). For a kitchen, the delivery rate of this electric fan must guarantee an hourly
air exchange of 3-5 times its volume. In both instances, the use of flues already used
by other appliances to discharge the flue gases is not recommended.
