Installation instructions
The following pages give instructions for the safe and proper installation of this heating ap-
pliance in the UK. These instructions cover the basic principles of installation, although detail
may need slight modification to suit particular local site conditions. In all cases the installa-
tion must comply with current UK Building Regulations, Local Authority Byelaws and other
specifications or regulations as they affect the installation of the stove. Please note that it is a
legal requirement under England and Wales Building Regulations that the installation of the
stove is either carried out under Local Authority Building Control approval or is installed by
a Competent Person registered with a Government approved Competent Persons Scheme.
HETAS Ltd operate such a Scheme and a listing of their Registered Competent Persons can
be found on their website at www.hetas.co.uk.
It should be noted that the current Building Regulations requirements are given in Approved
Document J. These requirements may also be met by adopting the relevant recommenda-
tions given in British Standards BS 8303, BS 6461 and BS 7566.
WARNING: Health and Safety Advice Notice
The installation of this heating appliance is governed by the Health and Safety at Work Act
1974. It is the responsibility of the installer to ensure that all requirements of this Act are met
during the installation works. Attention is drawn in particular to the following:
Handling:
The appliance is a heavy item and adequate facilities must be available for loading,
unloading and site handling.
Fire Cement:
Some types of fire cement are caustic and should not be allowed to come into contact
with the skin. Protective gloves should be worn when handling fire cement. In case of
contact with the skin wash immediately with plenty of water.
Asbestos:
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in
the course of installation then please seek specialist guidance and use appropriate
protective equipment.
Metal Parts:
When installing or servicing this stove care should be taken to avoid the possibility of
personal injury.
Important Warning –Preparatory Work and Safety Checks:
This stove must not be installed into a chimney that serves any other heating appliance.•
There must not be an extractor fan fitted in the same room as the stove as this can cause•
the stove to emit fumes into the room.
If this appliance is installed into an existing chimney, the chimney must first be swept•
and examined for soundness and suitability before the appliance is installed (see also
section headed “Chimney”).

ENGLISH RAIS - manual for GEO

Chimney
The chimney is the driving force which makes the stove function. In order for the stove to
perform satisfactorily the chimney height must be sufficient to ensure the correct draught
of 14 to 18 Pa so as to clear the products of combustion and prevent problems of smoke
emanating into the room when firing.
NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet
of the stove to the top of the chimney should be satisfactory. Alternatively the calculation
procedure given in BS 5854:1980 may be used as the basis for deciding whether a particular
chimney design will provide sufficient draught.
The outlet from the chimney should be above the roof of the building in accordance with the
provisions of Building Regulations Approved Document J.
If installation is into an existing chimney then it must be sound and have no cracks or other
faults which might allow fumes into the house. Older properties, especially, may have chim-
ney faults or the cross section may be too large i.e. more than 230 mm x 230 mm. Remedial
action should be taken, if required, seeking expert advice, if necessary. If it is found necessary
to line the chimney then a flue liner suitable for solid fuel must be used in accordance with
Building Regulations Approved Document J.
Any existing chimney must be clear of obstruction and have been swept clean immediately
before installation of the stove. If the stove is fitted in place of an open fire then the chimney
should be swept one month after installation to clear any soot falls which may have occurred
due to the difference in combustion between the stove and the open fire.
If there is no existing chimney then either a prefabricated block chimney in accordance with
Building Regulations Approved Document J or a twin walled insulated stainless steel flue to
BS 4543 can be used. These chimneys must be fitted in accordance with the manufacturer’s
instructions and Building Regulations.
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not
suitable for using for the complete chimney. The chimney and connecting fluepipe must
have a minimum diameter of 150 mm and its dimension should be not less than the size of
the outlet socket of the stove which is 150 mm in diameter. Any bend in the chimney or con-
necting fluepipe should not exceed 45°. 90°bends should not be used.
Combustible material should not be located where the heat dissipating through the walls
of fireplaces or flues could ignite it. Therefore when installing the stove in the presence of
combustible materials due account must be taken of the guidance on the separation of
combustible material given in Building Regulations Approved Document J and also in these
stove instructions.

If it is found that there is excessive draught in the chimney then either an adjustable flue
damper or alternatively a draught stabiliser should be fitted. The adjustable flue damper
should not close off the flue entirely but should in its closed position leave a minimum
continuous opening free area of at least 20 % of the total cross sectional area of the flue or
fluepipe.
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping
the chimney and connecting fluepipe.
You should also familiarise yourself with the draught conditions for chimneys with 2 flues.
The flue outlet spigot is 150 mm in diameter.
For strong draughts, the chimney or flue should be fitted with a draught stabiliser. In which
case, it is important to ensure that there is a free flow-through area of minimum 20 cm² when
the regulating gate is shut. Otherwise, the fuel energy may not be used optimally. If, at any
time, you are unsure about the condition of the chimney, you should contact a chimney
sweep.
Remember that access to the access door should be kept clear.

Installation
It is prohibited to carry out unauthorised alterations to the stove.
There must be plenty of fresh air in the room where the stove is being installed, in order to
ensure proper combustion. Note that any mechanical exhaust ventilation - e.g. an extraction
hood - may reduce the air supply. Any air grates must be placed in such a manner, that the
air supply is not blocked.
Building Regulations Approved document J gives specific guidance on the required
permanent ventilation into the room for combustion air of solid fuel appliances.
The floor structure must be able to carry the weight of the wood burning stove, as well as the
weight of a chimney, if necessary.
When you choose where to set up your RAIS wood burning stove, you should consider the
heat distribution to the other rooms. This will enable you to get the best use out of your
stove. The stove should be set up at a safe distance from inflammable materials. See the
manufacturer’s plate on the wood burning stove.

1. Place the stove where you want to install it (it cannot be moved after the soapstone is
installed).
a) Rear exit can be installed when the third row of soapstone is installed - only GEO
161.
The distance at the top between the sides of the stove is 250 mm, and fits the RAIS
flue pipe, which is 150 mm and 90° tee with or without cleaning door.
b) For top exit:
Remove the marked opening with a plastic or rubber hammer.
Installation up at the ceiling:
When using this type of installation, the easiest approach is to use the RAIS sliding
flue system and a 570 mm adapter. The steel top plate should be pushed on the flue.
2. Adjust the legs so they are level.
- Loosen the counter screw
- Adjust the leg
- Tighten the counter screw
3. Place the soapstone as shown on the diagram and screw them together with the
enclosed mountings.
Depending on the choise of flue exit, you are left with either one piece of soapstone
no. 7023 or 7033/7036.
4. Insert the firebox.
a) Ensure that the firebox is centred within the stove (it must not touch the soapstone)
b) If you are using the rear exit, ensure that the exit holes are aligned. If you are using
the top exit, this alignment issue is irrelevant.

Installation distance in case of combustible wall
To find out whether the wall next to where the stove is going to be installed is flammable,
you should contact your building contractor or the local building authorities.
The hearth should be able to accommodate the weight of the stove. The chimney must be
independently supported by wall brackets or a ceiling support plate. The weight of the stove
is indicated in the brochure.
The stove should always be installed on a non-combustible hearth of a size and construction
that is in accordance with the provisions of the current UK Building Regulations Approved
Document J.
If the stove is to be installed on a wooden floor, it must be covered with a noncombustible
material at least 12mm thick, in accordance with UK Building Regulations Approved Docu-
ment J, to a distance of 300 mm in front of the stove and 150 mm to each side measuring
from the door of the combustion chamber.
The clearance distances to combustible material beneath, surrounding or upon the hearth
and walls adjacent to the hearth should comply with the guidance on the separation of com-
bustible material given in UK Building Regulations Approved Document J and also in these
stove instructions.
