Discharge Of Flue Gases - Elba EGH-B9230G Owner's 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
3
have an unobstructed cross-section not 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 inside or outside, or constructed close
to the floor. The opening is recommended to be 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;
·this room has ventilation;
·the ventilation between the room where the appliance
is installed and the adjacent room has 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 forbidden.
