General Comments
This RAIS/
attika product is an extremely effective convection gas stove
with a sealed combustion chamber for chimneys with a balanced draught.
It is fitted with a burner with the latest burner technology. It has a var-
iable heat output because it uses a special control system that makes it
possible to use three burners for high output or one burner for a lower
output. One of the burners, called the "Main burner" is located in the
centre of the stove, the second and third burners, called the "Secondary
burners" are located behind the Main burner. The secondary burners can
be switched on and off while the stove is on.
Where there is a natural gas connection, the local gas supply conditions
should be investigated to ensure that the gas composition and pressure
suit the stove's settings.
If the stove is connected to bottled gas, only gas bottles fitted with a gas
regulator (Low pressure regulator) providing the correct gas pressure may
be connected. For this reason, gas bottles without a regulator must not
be connected.
This stove must only be installed, set up and serviced by a Gas safe reg-
istered Engineer. The installation must comply with local and national
Building Regulations and Gas Regulations and the user manual must
be adhered to. The user manual should be left with the customer, who
should keep this for later use. The manual is necessary when the stove is
to be serviced.
Ensure that the chimney terminal is not blocked in any way and is free of
vegetation in the form of trees, bushes etc. and that objects are not rest-
ing against the chimney's terminal or the protection around the terminal.
The door glass should always be cleaned before the stove is turned on
and fingerprints wiped as these can be burned into the glass.
The stove must not be used if the door glass is split, cracked, re-
moved or if the door is open. Do not use the stove if the door
gasket is broken or worn.

This stove is designed for use in many different installation situations,
which can be seen in this manual. Only chimneys approved by RAIS/
at-
tika
may be used with this product. (see chimney section)
This stove is intended for chimneys with balanced draughts (Air intake
and draught in same chimney) so there is no need for any extra air sup-
ply for combustion.
This product is a heating appliance so the surfaces become very
hot and should not be touched during use. It is therefore recom-
mended that you use an approved stove screen to protect chil-
dren, vulnerable adults, older people and persons with reduced
mobility in the same area as the stove.
Keep curtains, washing, furniture etc. at a minimum distance of 300 mm
from this stove.
The stove must not be used for burning waste.
If the stove is extinguished or goes out, do not attempt to turn it back
on until a minimum of 3 minutes have passed.

10
Emergency interruption of gas supply
Where a smell of gas is detected, the gas supply must be interrupted
immediately. Turn off the stove at the isolation tap and the gas meter
Ventilate the room by opening windows and doors, do not use electrical
appliances in the vicinity of the stove. Or operate any electrical switches.
The gas supply must not be switch on, until a Gas Safe Registered engi-
neer has checked the system and deem it as being safe.

Installation
It is important that the stove is correctly installed from both an environ-
mental and safety point of view.
The stove must only be installed by a Gas Safe Registered engineer.
When installing the stove, all local rules and regulations, including those
referring to national and European standards must be complied with.
The installation must comlpy with the Building Regulations and Gas Safe-
ty (Installation and use) Regulation.
There must be no unauthorised modifications of the stove.
Before installation begins, it should be confirmed that the information
on the data plate regarding gas type and pressure is in accordance with
the local gas supply conditions under which the stove is to be installed.
You should ensure that the gas supply can supply the required quantity
of gas and pressure as described on the data plate. It is advisable to wear
gloves when installing and servicing the stove.
Gas connection
The inlet supply pipe has an external diameter of Ø8mm. An isolation
tap must be fitted.
Ventilation
This stove has a sealed combustion chamber and is intended for a bal-
anced draught. There is therefore no need for an extra air supply.
It is recommended that sufficient fresh air is supplied to the room to
maintain a comfortable environment.
This stove may be installed in a completely airtight building or a building
with mechanical ventilation.

Gas installation
Once it has been decided where the stove will be positioned, a gas in-
stallation should be established in the vicinity of the stove so that the gas
supply and stove can be connected.
As this stove has a sealed combustion chamber and a built-in plinth,
there is no need for a floor slab.
The installation must comply with the Building Regulations, Gas Safe-
ty (Installation & USe) Regulations, BS 5871, BS 5440-1, BS 6891 and
where relevant all LPG Codes of Practice. LPG stoves must not be fitted
in a basement.

13
PLEASE NOTE!
The floor construction must be able to bear the weight of the stove and
chimney, if applicable. If the existing design does not satisfy this prereq-
uisite, suitable measures must be taken (e.g., a load distribution slab).
Consult a construction expert.
The stove must be positioned at a safe distance from flammable materi-
al.
It must be ensured that flammable objects (e.g., furniture) are not po-
sitioned closer than the distances stated in the following sections with
regard to installation (risk of fire).
When you choose where you wish to position your stove, you should
consider the heat distribution to the other rooms. Then you will get the
maximum possible pleasure from your stove.
Inspect the stove for defects upon receipt.
Changes to chimney connection
The stove is supplied ready for a top outlet but can be changed to a
rear outlet in the following manner:
