Directions for use and Installation Instructions
A fi replace insert can be fi tted in the newly-built or existing chimney breast
of an open fi re. When fi tting, both fi re safety and operational safety must be
safeguarded. The fi tter is responsible for this.
General guidelines:
• If there is a wooden beam above the fi tting location, heat must not radiate
directly onto it. An insulation plate must be hung below the beam, leaving an
air gap between it and the beam of at least 1 cm.
• Always use (white) unbound ceramic insulation wool. Bound material
(yellow), such as glass and rock wool, spreads an irritating smell on heating,
causes excess smoke and is unsuitable for high temperatures (insulation
requirements: temperature
≥
700°C, density 80 kg/m
3
).
• Before fi tting, remove the door to protect the glass.
3.3.1 Aeration / ventilation
A fi replace insert generates : - heating air
- combustion air
Heating air (convection air) is devoted to the convection of heat from the
appliance to the room. No other provisions are necessary. The source of heat is
in the room and stays there.
Combustion air is needed to keep the combustion going by drawing in air from
the room due to the natural draught of the chimney.
The intake opening for the air is under the door. When using the appliance,
please ensure there is a suffi cient supply of fresh air: minimum 50 cm
2
(Ø80 mm)
opening in the room where the fi re is placed.
Make sure that the ventilation supply is open; this is particularly important with
today’s airtight dwellings.
If the dwelling has mechanical ventilation that creates under pressure in the
room where the appliance is located, it is necessary to fi t a fl ue gas fan. The
type of fl ue gas fan is dependent on the capacity of the mechanical ventilation
system. Always consult your fi tter about this.
