INSTALLATION INSTRUCTIONS
- Install the oven on surfaces with adequate load-bearing
capacity.
- Safety must be the first priority. When the oven is in
operation ensure that no other fuel and materials that
may be damaged by heat and sparks are close to it.
- The outer walls of Quick may reach high temperatures
greater than 50°C.
- Position the oven so it is not in contact with the wall or
other furniture and make sure there is a gap of at least
20 cm.
- The upper part of the appliance can not be recessed
and must remain free from furniture that compromise
the correct ventilation.
- The accessory works must not rest on the structure of
the oven.
- Do not move the oven while it is in use.
- In the case in which there are presence of other devices
that create depressions within the environment, must
take account of them for the correct dimensioning of the
aeration and ventilation system.

1. VENTILATION
The A1 appliances must be installed in well-ventilated
areas to prevent concentration of substances hazardous to
health in the room.
1.1 Natural ventilation
Natural ventilation can be obtained by using one or more
permanent openings on walls/windows/fixtures or through
ventilation ducts. The net area of the ventilation openings
must be no less than 6 cm2/kW with a minimum of 100
cm2; in the presence of ventilation ducts, they must
have a cross-section of not less than 9 cm2/kW with a
minimum of 150 cm2. The ventilation apertures may be
made in the walls, on the doors or on the window systems
of the room or the combustion air room facing outwards;
they can be obtained by increasing the gap between
doors facing outwards and the floor of the room or the
combustion air room or they can be realized on the fixtures
facing outwards as long as the free air flow is guaranteed
and the net cross-section is measurable. The ventilation of the room can also be implemented by an individual
or collective ventilation duct provided that this pipework is impermeable to smoke and gas with neither change
in direction nor sharp edges. In case of indirect ventilation of the room where the gas appliance is installed, the
circulation of air between adjacent rooms may be ensured thanks to several air flow openings as long as each of
them has a net cross-section area of not less than 6 cm2/kW and provided that the sum of the net cross-sections
of the openings is not less than the calculated net useful cross-section of 6 cm2/kW. Such apertures can be made
in the walls or in the doors of the common walls or can be obtained by increasing the gap between the inner doors
and the floor of the premises as long as the free air flow is guaranteed and the net cross-section is measurable.
1.2 Forced ventilation
Forced ventilation can be obtained with systems equipped with electric fans.
The actual flow rate must be not less than 1,72 m³/h per kW.
The air velocity near the installation must not disturb the operators and must have specifically the following
characteristics:
- The air velocity next to the exhaust hood must be between 0,25 m/s and 0,5 m/s.
- The make-up air velocity must be less than or equal to 0,15 m/s up to 2 metres from the walking surface.
The vents for the air flow in the premises, facing outwards, must have the following characteristics:
a) To be conveniently located so as not to create a short circuit in the air flow
b) To be protected by grilles.
c) For LPG installations, at least 1/5 of the natural ventilation surface, with a minimum of 100 cm2, must be
14
coming from the floor.
