PRODUCTION NUMBER

IN 1830 Charles Portway built a stove to heat his ironmongery shop at Halstead in Essex. It was so good that his neighbours
started asking for them. Mr Portway had done something completely new designed his stoves right from the start to give out
the maximum heat from the minimum fuel, so that he is known as "The Founding Father of Energy Efficiency". The stoves
that bear his name are still made in Britain by the direct successors of the company he established.
Building regulations are available at www.soliftec.com
INST LLING 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.
SBESTOS: 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 weight- consider
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
150mm diameter, 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
baffle removed, fit hatches to provide access if needed.
YOUR FIREPL CE: Stoves become VERY hot, the setting must be
made entirely of durable fireproof materials. Thin (<50mm) stone slabs
risk cracking unless cut into sections to allow for expansion and
backed with a heat resistant concrete. Even beyond the safety
clearance items can still become very hot - take great care in siting
wax, paper etc. Inset convector stoves deliver very hot air into the
room, so that the 350mm clearance above to combustible materials
must be strictly observed.
FRONT HE RTH: To guard against fallen embers and protect against
fire we recommend a solid non-combustible hearth, which may simply
be an area of solid flooring, extending at least 300mm in front of the
appliance, no matter at what height the stove is fitted.
IR SUPPLY: Your stove needs air to breathe - there must be a
permanent fresh air supply to the stove, provided either by:
(1) AIR SUPPLY FROM OUTSIDE THE BUILDING:
Remove the rear air port and fit connector and 75mm flexi air supply
tube direct to outside. Make sure the inlet can't be blocked by snow,
rodents, etc.
(2) AIR SUPPLY IN THE ROOM:
Remove the front air port. There should be an air supply from outside
the building into the room in which the stove is installed equal to about
550mm² for each kW of output. This can often be provided by air
leaking around door frames etc. (it is commonly accepted that this
alone may suffice for appliances <c.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.
FITTING
The stove must be fixed down to the solid hearth through the two points under the base insulation panels. It may be connected to the chimney
flue in many different ways, three of which are shown here. If required, the lower frame bar ('LFB') may be removed.
◄ 'FREE INSET' or 'CASSETTE'
METHOD (3):
The stove is fitted inside a hollow chimney
breast which is ventilated to the room at
high and low levels, creating extra hot air
circulation. The stove flue is connected to
the chimney using up to 1.5m of
uninsulated flue pipe.
CONVECTION
This Portway stove is not just a
'firefront' or a simple 'inset stove',
but a genuine hot-air convector
fire. It has a very precisely
shaped, sealed chamber,
behind, above and underneath
the fire to collect heat and
naturally force a stream of
extremely hot air into the room,
to evenly heat every corner.
'FIREPLACE SEAL' METHOD (4): ►
Fix the stove and, through the flue outlet,
fill any gap behind with vermiculite
granules topped with mortar. Carefully
check that the fire has an absolutely
airtight seal against the fireplace.
'CHIMNEY SEAL' METHOD (5): ►
Remove the round connector. Fit the flue
pipe, or flexible liner with a 150mm
adaptor, into the chimney and seal its
loose end to the round connector with fire
cement. Fix the stove. Bolt the connector
and pipe back in place from inside. Check
that the pipe forms a clear route from stove
to chimney terminal with no leaks into the
masonry space.
Whichever 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 CO alarm!

fire-guard should be used if children or the infirm are
present. The installer is required to EX CTLY follow
these instructions and to completely comply with all
local, national and international standards.
(1) AIR FROM OUTSIDE (LEFT) remove rear blank and fit to 75mm alloy
flexi tube. (2) AIR FROM ROOM (RIGHT) remove front air port.

HOT IR DISTRIBUTION
Hot air can be distributed
from the stove to other
rooms using the
Convented Hot Air Duct
kit available as an extra.
The 125mm alloy
ventilation tube is
connected to one or
other of the opened vents
located to left and right of
the central flue outlet on
the top back of the stove,
using the connectors
provided.
Where this is used, the
following must be VERY
STRICTLY observed:
●Joins throughout the hot-air duct must be completely and
permanently sealed, using, for instance, a solid aluminium duct-
tape.
●The hot-air duct must be entirely and permanently separated from
the flue. Smoke and waste gas must never be able to contact even
the outside of the hot air duct.
●The hot-air duct must rise continuously - no falls and no horizontal
lengths.
●The hot-air duct, and its outlet grille must be entirely unrestricted.
●The entire duct system and its surroundings, must be capable of
withstanding temperatures up to 350°C.
●There must be a route for the heated air to return to the front of the
stove. An open doorway or floor vent. Without a clear circulating
route - it just won't work!
●Fit a CO alarm in the room hot air is being circulated to, as well as in
the room with the stove.
CHECK THE INST LL TION !
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
5) Fit CO alarms!
LIVING WITH YOUR STOVE
Every fuel, chimney and condition of use is different. Only experience
will show which are the best settings for you.
PREP RING THE FIRE FOR USE Make sure the flue is clear and that
the liner set is correctly installed (see diagram on back page). The
smaller inner liner set can be fixed in place for a firebox creating about
5kW heat output, or removed to give a larger fuel space suitable for
creating about 7kW heat output.
LIGHTING If lighting after a period of non-use, do check that the
flueways and chimney are completely clear.
Don't remove ash unnecessarily! The Portway Panoramic is a true flat-
bed woodburner. It will burn best if a layer of ash is maintained.
(1) Fully open the air control - ie. move to the right. Place two or three
firelighters close together, or screwed-up paper, cover with thin, dry
sticks, at the front of the stove and light them. To get the fire going
quickly, it may be helpful to keep the door just a tiny fraction open
When they are burning well, use a poker to distribute the hot embers
and gently add just two or three dry logs, close the door. Once the logs
are burning well, set the air control to the lowest practical setting.
FILLING: Filling too full will waste fuel, create smoke and reduce
efficiency. Just adding one log every hour or so is all that is needed.
Don't fill above the level shown in the diagram.
CONTROL How fast the fire burns depends on how much air reaches
the fuel. There is only one control. Slide to the right for higher output,
to the left for lower.
EMPTYING SHES The white powder deposited as wood burns is not
ash but cellulose, which this appliance is designed to burn away,
leaving only a slight residue of brownish, gritty, true ash. Help the fire
work best by maintaining a bed of ash and cellulose - it is only
necessary to remove a little if it is actually at risk of overflowing,
normally just once every few weeks.
Remember to let residues cool before disposing in plastic sacks or
dustbins.
KEEPING THE WINDOW CLE N Reduce the risk of staining by using
only very dry fuel. 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 plain water and a coarse
scourer. 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 heat-resistant material known.
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 – use a glove when touching hot parts.
SUMMER SHUT DOWN: Before a long period of non-use, empty fuel
and ash and leave all the air controls open to allow ventilation to
reduce condensation.
FUEL
This appliance is designed to burn dry wood logs only.
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.
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.

Air circulating route

●Fill 'little and often' - one log every 30 to 0 minutes is usually all
that is needed.
●When first lighting, or reviving a fire from embers, use only very
small, thin, dry, sticks.
JOINERY W STE Dry wood offcuts will burn well, but don't expect
softwood waste to burn as cleanly or for as long as hardwood logs.
PROBLEMS?
Problems like those listed here are usually due to some difficulty with
the installation, chimney or fuel, so please check back through this
leaflet carefully. If necessary seek specialist advice.
SMOKE FROM THE CHIMNEY A little smoke will be emitted when
the fire is first lit. Once hot, barely any smoke should be visible, though
steam may be seen if damp fuel is used. Use only VERY dry wood.
D M GED 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.
HE T 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 may cause excessive fuel use and damaging overheating.
CONDENS TION 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 control to the lowest practical setting.
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 slight 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 the
inset appliances fully seal against the fireplace?
BLOCKED BAFFLE: Has soot and ash collected on the baffle above
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.
The answer is to fit an outside air vent, as near to the fire as possible,
facing into the usual wind direction.
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- Draught in use MUST be 12Pa.
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.
M INTEN NCE
MONTHLY- With the fire cold, carefully check that the flue is clear and
unblocked, that there is no build-up of deposits behind the baffle and
that the door seals are sound.
NNU LLY- SWEEP THE CHIMNEY The entire length of the chimney
from stove to outlet should be swept annually.
NEW P RTS Your stove has been extensively tested for safety -
please don't try to modify it and always obtain genuine spare parts.
SURF CE FINISH Wipe the stove body with a slightly damp cloth
when cool. Don't 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 very dry,
fuel.
