YOUR NEW GAS FIREPLACE IN GENERAL
NB!
RAIS/ATTIKA recommends 20 mm gas supply pipes for town gas burners.
Gas supply emergency stop
If you smell gas, immediately switch off the gas supply. Turn off the fireplace at the stopcock and
main switch.
Ventilate the room by opening windows and doors. Do not use electrical appliances or switches in
the vicinity of the fireplace. The gas supply may not be reconnected until an authorised heating and
plumbing/gas technician has examined the fireplace and approved it.
Your new gas fireplace in general
This RAIS/ATTIKA product is a highly efficient convection gas fireplace with a sealed combustion chamber
for a balanced flue system. The fireplace has variable heating power and is equipped with a burner which
has been developed using the latest burner technology.
Before installation
All local laws and provisions should be studied before installation. Always check the national building and
gas regulations.
In addition, it should be confirmed that the information on the information plate relating to gas type and
gas pressure is in accordance with the local gas conditions that the fireplace shall be installed under. The
gas supply should be examined to ensure that it can supply the required amount of gas and the required
pressure.
It is recommended that gloves are worn when installing the gas fireplace to avoid fingerprints on glass, etc.
Gas connection
This fireplace may only be installed, adjusted and serviced by an authorised and qualified heating and
plumbing/gas technician. The installation must comply with local and national building and gas regulations,
and the instructions in the installation manual must be followed. The installation manual and user manual
must be left with the customer, who must keep the manuals for later use. The manuals are necessary when
the fireplace is to be serviced.
The pipe on the gas hose has an external diameter of 8 mm. When it has been determined where the
fireplace shall be installed, a gas installation with a stopcock in the vicinity of the fireplace must be executed
to ensure that the gas supply and the fireplace can be connected.
Since this fireplace is equipped with a sealed combustion chamber, a floor plate is not necessary.
Hearths
Follow the guidelines in document J point 3.40 - 3.41 concerning hearths.
If the fireplace is connected to bottled gas, it may only be connected to bottle gas that is equipped with a
gas regulator (low pressure regulator) that supplies the correct gas pressure.
Ensure that the balanced flue system is not blocked in any way and is free of vegetation in the form of
trees, bushes, etc.
The glass must always be cleaned on the outside before the fireplace is lit. Fingerprints must be wiped off
as these can burn into the glass.
GB - 5
GB

SAFETY
Safety
It is important that the fireplace is correctly installed in consideration of the environment and people’s
safety. No unauthorised alterations may be made to the gas fireplace.
The fireplace may not be used if the glass is split, cracked or removed. Do not use the fireplace if the glass
gasket is broken or worn.
This fireplace is designed for use in many different installation situations, which are shown in this manual.
Only flue systems that are CE approved for this product may be used (see the section “flue system”).
This fireplace is designed for a balanced flue system (air intake and extraction in the same chimney).
Therefore there is no need for an extra air supply for combustion. It is recommended that the air replacement
in the room is adjusted to ensure a pleasant indoor environment. This fireplace can be installed in an
airtight building or in a building with mechanical ventilation, since the gas fireplace functions in a closed
system that does not extract combustion air from the room.
NB!
Due to the risk of fire, flammable items (e.g. furniture) may not be positioned closer than 700 mm
from the front of the glass.
This product is a heating appliance. This means that surfaces become very hot and must not be
touched when the fireplace is in use. It is therefore recommended that an approved screen is used to
protect children, seniors and persons with limited mobility who are in the vicinity of the fireplace.
If the fireplace is switched off or the fire goes out, wait at least three minutes before lighting it again.
