Building regulations are available at www.soliftec.com

INSTALLING a stove is a 'controlled service', the law expects that
it is either supervised by a qualified installer or that the building
inspector is informed. Check with your local authority.

ASBESTOS: Your stove does not contain asbestos, but take care
to avoid disturbing asbestos in an old installation.

WEIGHT: Your stove is heavy - take great care when moving it
and ensure that the intended fireplace can support the weight­consider fitting a load distributing plate.

YOUR CHIMNEY, by becoming warm, makes the gas inside it
rise, pulling fresh air into the stove to make it work. It must:

 Generate a draught in use of at least 12Pa (0.05ins wg)
 Be capable of withstanding the temperatures generated.
 Be absolutely incapable of leaking fumes into the dwelling

This may commonly be achieved by it:

 Being at least 5m high.
 Terminating at least 1m above any roof ridge.
 Having an internal cross-section equivalent to not less than

125mm diameter for No1, No2 and Inset models, 150mm dia for
No3, and never more than 0.14m² (eg 375 x 375mm)

 Being free from even the slightest crack or source of leakage.
 Having no bends sharper than 45º.
 Being swept and entirely free of obstructions
 Being connected only to this one appliance.
 Being of thick masonry or otherwise adequately insulated.
 Conforming to local building regulations.

Special rules apply where the flue passes through timber, thatch or
other vulnerable materials- take specialist advice.

Although it is possible to access the chimney through the fire with
the throat plate removed, fit hatches to provide access if needed.

YOUR FIREPLACE: Stoves become VERY hot, the installer must
specify a fireplace which will completely protect the building
against fire. A solid masonry hearth >12mm thick, extending at
least 250mm in front of the stove, 100mm at the sides is likely to
suffice, but other configurations are possible at the discretion of
the expert installer. Even beyond the safety clearances given on
the front page items can still become very hot - take great care in
siting wax, paper etc.

AIR SUPPLY: Your stove needs air to breathe - there must be a
permanent fresh air supply into the space in which it is installed
equal to 550mm² for each kW of nominal output. This can often be
provided by air leaking around door frames etc. (it is commonly
accepted that this alone may suffice for appliances <5kW) but in
any case of doubt, fit a purpose-made air vent. An extractor fan, or
another fuel-using appliance
in the same building, can
remove this air.

Your Luxima stove has a
built-in 'Proximity Air Supply'

- a feature of Portway stoves
since Victorian times which
supplies precisely the
required amount of air for
combustion and, when the
fire is lit, also circulates
warmed fresh air without
draughts. air. Fix the rear
connector to standard 100mm flexible tube and an open outside
air grille to fully conform to air supply requirements.

FITTING

Your stove can be sealed to the chimney using a short length of

125mm uninsulated pipe in several ways, two of which are shown.

The Luxima is available in two different firebox

configurations:

Through steel or concrete closure plate (with

cleaning door) into old, oversized, chimney.

Steel sealing collar. Hearth fixings also shown.

45º top outlet sleeved

through wall into external

insulated flue. Cleaning

hatches on bends.

(L) Multi-fuel version with grate

and ashpan, can burn wood logs

and the full range of authorised

smokeless fuels.

(R) Wood-only version, burns wood

logs only

Whichever model and method is used it is imperative that: (1) The route for gases from the stove to the chimney terminal is
completely air-tight; even the tiniest gap or crack can spoil the updraught. Seal all joins with fireproof cement and/or heatproof rope.
(2) It is possible to sweep the entire length- access doors may be required. (3) The entire construction is of durable fireproof materials.

(4) Fit a suitable CO alarm!

CHECK THE INSTALLATION !

Make sure that the stove is fully
assembled and sealed. Check
that the inner steel baffle
(shown dark on this cutaway
diagram (right)) is correctly and
securely fitted in place as shown.

Once installed, light the fire,
demonstrate it to the householder
and check that:

1) It burns controllably and does not emit fumes to the room

2) The route for gases from the stove to the chimney terminal is
completely airtight, unobstructed and able to be swept.

3) The entire construction is of durable fireproof materials.

4) The flue presents a draught in use of at least 12Pa

LIVING WITH YOUR STOVE

experience will show which are the best settings for you.

THIS APPLIANCE BECOMES EXTREMELY HOT

AND CAN PRODUCE POISONOUS GASES.

A fire-guard should be used if children or the infirm are

present. The installer is required to EXACTLY follow

these instructions and to completely comply with all

local, national and international standards.

flueways and chimney are completely clear. Empty the ashes.
Place two or three firelighters close together, or screwed-up paper
covered with dry sticks, at the back of the grate and light them.
When they are burning well gently fill the fire with dry fuel, close
the door and set the air control slides to the 'high' (right) position.
When the fire is burning well, move the controls to the lowest
practical setting.

FILLING: Don't fill above the level shown in
the diagram.

CONTROL How fast the fire burns depends
on how much air reaches the fuel. The
stove has two air controls, one below the
window ('primary' 1) and one above
('airwash control 2). Move the top slides to
the right for highest output, to the left for
'low'. The lower control is 'in' for low and
'out' for high. They can get very hot, so
move them only with the handle supplied.

Our tests indicate highest efficiency on
wood with the primary (1) control closed
and the airwash (2) at 2/3 open, but the
precise settings to suit your fuel and chimney can only be found
from experience.

EMPTYING ASHES: Use the tool or glove to open the door and ...
Mutifuel model: Stir the fire with a poker. Use the tool to lift out

the ashpan. Never allow ash to build up so as to touch the
underside of the grate. Wood-only model: Empty excess ash
using a spoon or scoop only when it is so full as to risk spilling
over the firebars. All: Remember to let ash cool before disposing
in plastic sacks or dustbins.

KEEPING THE WINDOW CLEAN Simply operating the stove for a
few minutes at high output will often burn-off any deposits left by
tarry or wet fuel. Severe stains can be removed when cold with a
domestic bleach cleaner. The window is not glass but a
transparent ceramic, it may develop tiny hairline cracks, these are
harmless, and a characteristic of the toughest and most heat­resistant material known. Reduce the risk of staining by using only
very dry fuel.

OPENING THE DOOR This stove is designed to be operated only
with the door closed. Open the door very slowly to minimise fume
emission and prevent hot fuel falling out. Remember that the
whole stove becomes extremely hot.

SUMMER SHUT DOWN: Before a long period of non-use, empty
fuel and ash, remove the throat plate and leave all the air controls
open to allow ventilation to reduce condensation.

FUELS

Do avoid dusty materials like sawdust, they can burn far to
violently.

SMOKE CONTROL: In certain areas special rules apply to reduce
smoke nuisance. Check with your local authority.

WOOD only emits as much carbon to the atmosphere as the tree
took in when growing, so wood is considered the 'carbon neutral'
fuel. When wood is cut down its cells are full of water. Burning
such wet or 'green' wood wastes heat in making steam and
produces flammable, acidic tars which will cling to, and rapidly
damage, your stove and chimney. Split logs will typically take two
years to become reasonably dry, round logs very much longer.
Cracks in the ends, a hollow sound when tapped and bark falling
away are all signs that a log may be ready for use. The fine, white
residue produced when wood burns is not ash, but the remains of
cell walls which can burn if kept hot enough, so don't de-ash the
fire until absolutely necessary when using wood.

For best performance, and always for low smoke emission:

Split logs lengthways for drying

 Use logs no bigger than about

100mm x 250mm

 Ensure logs are absolutely dry

(less than 20% moisture)

 Fill the stove criss-cross, so air

can circulate between logs.

 Fill 'little and often'
 Always have the airwash control (2) at least a little open.

 When first lighting, or reviving a fire from embers, use only very

small, thin, dry, sticks.

JOINERY WASTE Dry wood offcuts will burn well, but don't expect
softwood waste to burn as cleanly or for as long as hardwood logs.

OTHER FUELS With the multi-fuel grate and ashpan fitted, this
stove can burn a wide range of other fuels, including the full range
of authorised smokeless fuels, as recommended by your fuel
supplier and permitted in your region.

HOUSEHOLD WASTES Some plastics give off toxic fumes when
burned and remember that batteries and aerosols explode! The
stove is not an incinerator, so only ever use the recommended
fuels and NEVER use liquid fuels in any form.

DO NOT USE Don't use non-authorised 'smokeless fuels' or
'petcoke' - these are often made with dangerous high-suphur oil
waste and will rapidly damage your stove. Don't use cheap, raw
bituminous coal, sometimes sold as 'Polish Coal'.

PROBLEMS?

Problems like those listed here are usually due to some difficulty
with the installation, chimney or fuels, so please check back
through this leaflet carefully. If necessary seek specialist advice.

SMOKE FROM THE CHIMNEY It is quite normal for a little smoke
to be emitted from the chimney when the fire is cold. Use only
VERY dry wood or smokeless fuels.

DAMAGED LINERS The Portway stove gets very, very hot inside,
it is quite usual for the replaceable liners to crack or craze. They
need only be replaced when they have almost completely
disintegrated. Help them last longer by using only very dry fuel.

POOR HEAT OUTPUT: A stove can heat a typical room of about
12m³ volume for each kW of output, so a 5kW model can heat up
to (12 x 5) 63m³, a room of about 5m square. The actual size
depends on the insulation and air-change ratio of the room. To
attempt to heat a larger room will result in excessive fuel
consumption and damaging overheating.

LACK OF CONTROLLABILITY Wood and some other fuels may
burn excessively until the gases in them have been used up. You
can reduce this effect by making sure that the fire is set to 'low' for
a while before refuelling and checking that the door seals fully.
Adjust the heat output by how much fuel you put on, as well as by
using the controls.

CONDENSATION onto cool surfaces inside the stove can be
severe if fuel is in any way damp. Use only very dry fuel.

OVER-FIRING: It is possible to leave the fire too long with the
controls set too high leading to 'over firing', seen as glowing metal
parts, excessive chimney temperature and risk of parts failing or
chimney fires. Always set controls to the lowest practical setting. A
chimney thermometer, from your local stove shop, can help.

SMOKE COMING INTO ROOM Fumes are poisonous- smoke
emission must NEVER be tolerated, causes might be:

NEW STOVE: There is often a smell and sometimes visible fumes
as the paint cures. This normally stops after an hour or so.

INADEQUATE SEALS: Are all flue pipes and connectors
absolutely gas-tight? Even the tiniest crack or gap can spoil the
draught. Does an inset appliances fully seal against the fireplace?

BLOCKED THROAT PLATE: Has soot and ash collected on the
'throat plate' above the inner back part of the firebox?

UNSUITABLE, BLOCKED OR UN-SWEPT CHIMNEY: The first
requirement for correct operation is a sound chimney. Check the
requirements earlier in this document and in any case of doubt
engage a professional sweep or chimney engineer.

POOR AIR SUPPLY: Lack of air to the fire is a common cause of
smoking and poor performance. Air supply problems may be
worse in certain wind conditions (often incorrectly ascribed to
'downdraught', which is in fact very rare), where air can be sucked
out of the room.

DOWNDRAUGHT: Wind can blow down a chimney if there is
something higher nearby such as a tree, hill or high building.
Fitting an anti-downdraught cowl to the chimney top can cure this.
Types which cannot be swept through are not recommended.

POOR CHIMNEY DRAUGHT- Chimney draught in use MUST be
at least 12Pa.

3

CHIMNEY FIRE: In the rare event of deposits inside the chimney

igniting (roaring sound + dense smoke and sparks from the
chimney) immediately close the door, shut all air controls and call
the fire brigade. Prevent fires by using very dry fuel and having
your chimney swept regularly.

MAINTENANCE

MONTHLY- With the fire cold, remove, clean and refit the throat

(or 'baffle') plate below the flue outlet. Check that the flue is clear
and unblocked, and that the door seals are sound.

ANNUALLY- SWEEP THE CHIMNEY The entire length of the
chimney from stove to outlet should be swept annually, more often
if smoky fuels are used.

NEW PARTS Your stove has been extensively tested for safety ­please don't try to modify it and always obtain genuine spare parts.

SURFACE FINISH Wipe the stove body with a slightly damp cloth
when cool. NEVER use aerosol spray or wax near the hot fire –
they can ignite. Painted steel parts can be refurbished using
special spray paint.

Your stove generates VERY high temperatures. Eventually the
internal parts will require replacement . Help parts to last by:

 Using only recommend, very dry, fuels.
 Cleaning the throat plate regularly.
 Avoiding 'over-firing'
