Flue and Chimney Requirements
BS 5440 : PART 1
Before installation of the appliance, the chimney or flue system must be inspected and passed as suitable.
In particular, the following should be checked:
a) This appliance is suitable for installation onto the following flue types:
A suitable sized diameter flexible or fabricated steel flue system (See appliance data for
flue size), or a precast flue system (See Technical Bulletin TB118).
b) We would strongly recommend that a flue liner is also fitted if being installed into an existing
chimney built with an integral clay liner.
c) If being installed into an existing masonry flue which has NOT been built with an
integral clay liner, a flexible flue liner MUST always be used to line the entire chimney.
NOTE:
Any steel flue systems used should be manufactured in line with the requirements of BS 715, and
installed with due regard to the manufacturers recommendations.
d) The chimney should be thoroughly swept prior to installation of the flue liner. However,
if the flue is clean and unobstructed throughout its entire length, it need not be swept.
e) The chimney or flue must be free from any obstruction. Any flue damper or restrictor
must be removed or permanently fixed in the fully open position.
f) The minimum effective height of the chimney or flue must be 10ft (3 metres) measured
from the hearth to the termination of the flue (chimney pot). If the flue has any non
vertical sections the height should be increased in line with BS 5440 : Part 1.
For further information see the Euroheat Flue Guide IN1087.
g) An approved gas flue terminal MUST be fitted in accordance to the manufacturers
recommendations.
h) Where required a closure plate, of a suitable non-combustible material should be fitted. This
should have an infill panel so as to facilitate removal of any debris that may fall down
the chimney. Even after sweeping soot or debris may continue to fall down the chimney.
Ventilation
BS 5440 : PART 2
Before proceeding further, the following ventilation requirements must be satisfied.
a) If the stove is installed in a builder’s opening or fireplace recess that has an air supply entering from below
floor level, or within the opening or recess, this must be completely sealed off.
b) If there is another gas appliance fitted in the same room, or adjacent area, or extractor fan system, air
conditioning, etc., it will be necessary to refer to BS 6714 and BS 5440 : Part 2 to ascertain the additional
precautions necessary.
If any of the pre-installation checks reveal inadequacies, the installation should not proceed until they are
rectified.
Do not fit the appliance, seek expert advice.

Installation of the Gas Supply
BS 6891
NOTE: Ensure that the gas supply is capable of delivering the required amount of gas, and is in
accordance with the relevant current standards.
It is generally preferred to conceal the gas supply by bringing it under the hearth, or through masonry to
the side of the fireplace. Any pipe work in 8mm tube connecting the stove to the main pipe work should be
kept as short as possible with as few fittings as possible to prevent restrictions.
a) Whenever a gas pipe passes through any masonry it must have a sleeve of non
combustible material sealed at both ends to prevent the gas supply from coming in
contact with masonry or lime based mortars.
b) The gas pipe should be adequately supported over longer lengths.
c) Soft copper tubing and soft soldered joints are suitable, providing the tube is not closer than
150mm to the stove casing, i.e., the temperature must not exceed 100°C.
d) A means of isolating the gas supply to the appliance must be provided, unless the
appliance is supplied with its own isolation valve, independent of any appliance control
(gas control valve). This may be a gas cock, ideally of the nursery type to prevent
children interfering with the gas supply.
e) Any gas tubing that has been passed through masonry, should be purged to expel
any foreign materials that may have entered the supply.
Care should be taken to ensure that pipe work brought through metal structures has been secured to prevent
chaffing, but allow for thermal expansion.
Appliance Location
a) In a fireplace recess the stove can be mounted on a 12mm thick decorative hearth or plinth, if
a constructional hearth of the correct dimensions is in place. In a free standing situation, as the
hearth temperature does not exceed 100ºC, a constructional hearth is not required. The stove
can be mounted on a 12mm thick non-combustible decorative hearth of the correct size i.e. a
cast iron plinth, provided that the floor can support the weight.
b) The stove is not suitable for installation into a rear combustible wall, any combustible
material must be removed from an area of 300mm around the installation of the appliance.
c) There must be a minimum of 300mm (see page11) from the top of the stove to the
underside of any combustible shelf. Note that for every 50mm increase on clearance, the
shelf may project by a further 50mm.
d) The appliance must not be installed in a room or space which contains a bath or shower, or if the
room is used as sleeping quarters.
e) Ensure that the stove fits neatly into its intended location.
f) Any manufactured surround used with this stove should comply with the appropriate British
Standard.
g) Do not place furniture or furnishing within 1 metre of the stove.
h) Do not obstruct the area directly beneath the stove as this may block the passage of air into
the appliance.
If any of these conditions are not fulfilled,
DO NOT FIT THE STOVE until the problem has been rectified.

Installation of the Stove to the Flue System
Refer to page 6 to determine which flue systems are suitable for your stove size, having selected a suitable
flue system, please follow the applicable installation method.
Installation to a Flue Pipe System
IMPORTANT: The flue pipe system should be manufactured in line with BS 715, it should be either
a flexible flue liner or a rigid tubular steel construction, and it must be continuous from appliance
outlet spigot to terminal.
IF IT IS INTENDED TO FIT INTO AN EXISTING MASONRY BUILT CHIMNEY SYSTEM A SUITABLE DIAMETER
FLEXIBLE FLUE LINER MUST BE USED.
(See page 4 appliance data for flue size)
If fitting to a pre cast flue system refer to Technical Bulletin 118.
The stove is factory assembled for top flue connection. To choose a rear flue option follow the instructions
on page 10.
The flue system may now be connected to the stove, ensure that all joints are sealed with a suitable fire
resistant sealant we recommend Fraxfill (available from Euroheat Part No: MS9045).
Some so called “Heat Proof” mastiks will only stand a temperature of 300°C before they start breaking down.
In many cases they may give off an obnoxious smell at temperatures much lower than this and therefore
should not be used on this type of installation.
A physical retention method MUST be used at the flue spigot joint with the flue pipe, self tapping screws
being favoured.
Note:
If the flue is to be connected to the rear outlet, there should be no more than 150mm of horizontal
flue run before the flue rises vertically. Under certain circumstances it may be necessary to use a 45
degree bend directly from the top of the stove, this is acceptable as long as it does not compromise
the performance of the flue and the stove passes the necessary flue spillage test.

© EUROHEAT DISTRIBUTORS (H.B.S) LTD. June 2009 E & OE Instructions Part Number IN1113 Ed. E
10
Changing Flue Outlet Direction
The stove is factory assembled for top flue connection. To change to the rear flue option carefully remove
the flue spigot and the two cast iron parts of the top flue adapter (see diagram).
Refit flue spigot to the back
of the stove using the gasket
as a seal ensuring that the
choke plate is also fitted.
Fit the half moon blanking
plate, found in the bag of
installation accessories, in the
recess left by the removal of
the top flue spigot.
When connecting the flue
system to the stove, ensure
that all joints are sealed with a
suitableheatresistantsealant.
It is also recommended that a
physical retention method be
used at the flue spigot joint,
self tapping screws being
favoured, when the rear flue
option is used.

Hearth and Fireplace Requirements
Do not be tempted to fit the stove into an unsuitable fireplace. Beyond the requirements of the building
regulations and access to facilitate servicing the stove, providing a setting which will complement the stove
is not a luxury, it is the practicality of making the most of an investment. A good builder will be able to
transform even the most utilitarian of fireplaces, whether altering its proportions to those of the “Golden
Mean” ideal, exposing a wooden lintel, stone or simply removing superfluous detailing for comparatively
small costs, and the result will be a pleasure for many years.
The measurements are for advice only. In
all installations surrounding inflammable
materials must not exceed 80ºC. Curtains
and furniture must be a minimum of 1m
from the stove. The stove must always
stand perfectly level and have sufficient
space allowed for service work.

Installation of the Gas Log Effect
If any of the components of the log effect or burner are broken DO NOT INSTALL. Contact your stove supplier
for replacements. The log effect kit is not covered by the stoves warranty for accidental damage, so great
care should be taken when handling the ceramic burner and logs. It is important that the logs, ember glow
fibres and ember cubes are installed in accordance with these instructions as any deviation may cause poor
combustion. The addition of further ceramic logs or cubes is strictly prohibited.

Place fibres and cubes
to the side of this
area.
Pilot Ignition Route
Do not compress the embers or force into
position.
Placement of the Ember Glow Fibres
Platinum ember glow fibres are for use in vented gas appliances only. Platinum ember glow fibres are
made from high grade ceramic wool. The wool is similar to fibreglass and should be handled carefully. We
recommend the use of suitable dust mask, gloves or tweezers when placing the embers in position. Wash
hands immediately after touching to avoid irritation. Do not store the embers close to flammable liquids.
The embers must be placed correctly in order
to function properly. Tease out the fabric to
form loose, irregular shapes.
Use of Embers
With the embers correctly placed they glow and flicker similar to glowing ash. Their placement is important
as the effect produced can only occur when they are heated by the gas jets or by direct radiated heat. Once
the burner has been lit the embers may need adjusting to give the required effect.
The pack containing the ember glow fibres contains more than is required.
The additional embers should be kept for further service requirements.
Important:
Tease out fabric to form
loose, irregular shapes.

14
Fitting the Log Effect Kit
This is very fragile and should be handled with the utmost care. Ensure that all transport packaging which
held the ceramic burner in place in transit has been removed.
Position the main log at the rear of the burner, so that the flat surfaces of the rear log and burner sit
together.
Place ceramic ember cubes along the holes of the burner underneath the rear log with teased out sections
of ember glow under each ember cube, leaving about 5mm between each cube. Do not place ember cubes
or ember glow on the pilot ignition route (see previous page) Gently rub the ember glow into the burnt
surfaces of the log.
Fit the left hand log with the larger end on the burner and the smaller end against the rear log. There is a
small groove next to the left circular secondary air hole. The left log has a chamfered edge which should be
located into this groove. Gently rub the ember glow into the burnt surfaces of the log.
Left log fits into groove in
burner surface

© EUROHEAT DISTRIBUTORS (H.B.S) LTD. June 2009 E & OE Instructions Part Number IN1113 Ed. E
15
Fit the front log. In the centre of the burner is a groove for the front log to be located. Gently rub ember glow
into the burnt surfaces of the log.
Place ceramic ember cubes along the holes of the burner in front of and to the sides of the right hand log,
with teased out sections of ember glow under each ember cube, leaving about 5mm between each cube.
Place the front log in the front locating slot in the burner surface, then lean the log against the left log. The
ceramic cubes may have to be adjusted to allow the front log to sit correctly.
When the appliance is first fired small adjustments to the ceramic cubes and ember glow can be made to
achieve the desired effect.

Gas Connection
a) Connect the gas supply pipe to the 8mm connection under the base of the appliance. We advise
that no more than 1 meter of 8mm pipe is used to connect from the 15mm gas feed.
b) Connect a suitable gas pressure gauge to the test nipple on the gas valve, see page 18, turn the
gas supply on and check that the gas connections are sound. If satisfactory light the appliance.
Check all the gas connections on the appliance for leaks. The appliance is factory tested, but it is
possible for a connection to have been disturbed during transportation and installation.
c) Set the control to the high setting, and check that the gas pressure is as stated on the data table.
d) Turn off the gas, remove the pressure gauge and refit the test point screw, turn the gas supply
on and check that the test nipple is gas sound.
Lighting
Ensure the pipe work has been purged prior to following the lighting procedure.
Turn the on/off knob, smaller right hand control knob, towards the ignition position and press and turn
anti-clockwise. There will be an audible click as the Piezo spark is generated. If the pilot lights, hold down
the control knob for 30 seconds, if it has not lit then repeat the pilot lighting procedure to maximum of 6
attempts. If after 6 attempts the pilot has not ignited leave the appliance for 5 minutes before attempting
again.
Once the pilot has been established, let out the control knob and turn it fully anti-clockwise.
Manual Control
Turn the larger left hand control anti-clockwise to increase, clockwise to decrease the desired heat output.
