(b) Through to an outside wall but offset.
(c) Into a cavity ventilated to outside.
(d) Into an underfloor space ventilated to outside.
(e) Into a roof space ventilated to outside.
NOTE 2 The two openings may be combined
provided that the top and bottom of the opening
reach the limits set by this Clause.
Natural ventilation via adjacent room
Two permanent openings shall be provided in the
room or enclosure. The openings shall be located to
ensure the distance between the top of the upper
opening and the ceiling of the room or enclosure,
and the distance between the bottom of the lower
opening and the floor of the room or enclosure does
not exceed 5% of the height of the room or
enclosure.
The minimum free ventilation area provided by each
opening shall be calculated using the following
formula:
A = 6 × T
where
A = the minimum free ventilation area (cm
2
)
T = the total gas consumption of all appliances
(MJ/h)
These requirements shall apply to all subsequent
rooms until a room is ventilated to outside, in
accordance with the previous section, or the total
input of the appliances does not exceed 3 MJ/h for
each cubic metre of the total volume of the
enclosure and rooms.
The minimum vertical dimension of any free
ventilation opening shall be 6 mm.
NOTE: The two openings may be combined
provided that the top and bottom of the opening
reach the limits set by this Clause.
If an electric fan is used for extracting the
combustion products, the ventilation aperture must
be increased in relation to its maximum
performance. The electric fan should have a
sufficient capacity to guarantee an hourly exchange
of air equal to 3 ÷ 5 times the volume of the kitchen.
Prolonged, intensive use of the appliance may
require extra ventilation, e.g. an open window or a
more efficient ventilation system by increasing the
extraction power of the electric fan if installed. Liquid
petroleum gas descends towards the floor as it is
heavier than air. Apertures in the outside walls in
rooms containing LPG cylinders should therefore be
at floor level, in order to allow any gas from leaks to
be expelled. Do not store LPG cylinders (even when
empty) in basements or rooms below ground level; it
is advisable to keep only the cylinder in use in the
room at any one time and connected far from heat
sources which could raise its temperature to above
50 °C.
Range hoods
Range hoods and overhead exhaust fans must be
installed according to manufacturers instructions
but in no case shall clearance from hob burners be
less than 600 mm for range hoods and 750 mm for
overhead exhaust fans.
If the hood is installed below a wall cabinet, the
latter must be at least 700 mm (millimetres) above
the surface of the hob.
Safety Chain
In order to prevent
accidental tipping of
the appliance, for
example by a child
climbing onto the open
oven door, the supplied
safety chain must be
installed.
Ensure the chain is
secured to the rear wall
of the oven, and attach
the chain to a hook or screw secured to the wall
behind the appliance.
NOTE: If the cooker is placed on a base, measures
must be taken to prevent the appliance slipping
from the base.
This appliance is suitable for use with either a
flexible connection or rigid copper connection.
Check The Gas Type
!
Before installation, check that the gas type (natural
gas or LPG/Propane) of the cooker is suitable for the
gas type available to the installation. It is extremely
dangerous to use the wrong gas type with any
appliance, as fire or serious injury can result.
This cooker is supplied from the factory already set
for Natural Gas. To convert the cooker to LPG (or
back to Natural Gas from LPG), follow the directions
later in this section.
Fit regulator supplied for Natural Gas (if applicable)
at rear of appliance, and as close as practicable to
the appliance.
It is recommended that an isolating valve and union
be fitted, to enable simple disconnection for
servicing. These are to be in an accessible location.
Either a rigid metal pipe
with fittings in
compliance with the
standards in force must
be used for connecting
to the nipple union
(threaded ½G male
fitting) situated at the
rear of the appliance to
the right, or an
