4. BURNING WOOD
(Wood and multi-fuel stoves)
2. USING THE STOVE FOR THE FIRST TIME
2.1 When new, it is best to burn the fire at a low output for
the first few days of use. This will allow the construction to
settle and all fixing glues and paint to fully cure.
2.2 Avoid touching the paint during the first period of use.
2.3 During this time the stove may give off some unpleasant
odours, and we recommend that you keep the room well
ventilated during this period to avoid a build-up of fumes.
3. RECOMMENDED FUELS
3.1 Wood: Burn only seasoned timber, with a moisture content
of less than 20% with a recommended cut length of
300mm. In most cases, this would require drying cut wood
for 12 to 18 months before use. Poor quality timber could
cause low combustion efficiency, produce large amounts of
harmful condensation, which could reduce the effectiveness
of the airwash system, and ultimately the life of the stove.
3.2 Do not burn construction timber, painted, impregnated
/ treated wood, manufactured board products or pallet
wood.
For more details on using wood see Section 9 Burning
Performance, page 7.
3.2 Solid fuel: Burn only anthracite or a manufactured
briquetted smokeless fuels, listed as suitable for use with
closed heating stoves. Do not burn bituminous coal,
‘petro-coke’ or other petroleum based fuels, as this will
invalidate the product guarantee.
4.1 Open the Airwash control fully and open the Primary/
Thermostat* air control (multifuel versions only) to
approximately 25% open.
4.2 Place some pieces of firelighter or dry crumpled paper on
the grate and cover with some small pieces of dry kindling
wood. Light the paper or firelighters.
4.3 To avoid the build-up of condensation on the door glass
it is advisable to leave the door slightly open as the fire
establishes, and the glass warms.
4.4 As the fire becomes established add a few larger pieces
of wood and fully close the door. Do not initially add too
many logs as this may smother the fire. Do not leave the
stove with the door open as this could over-fire the stove
and cause permanent damage.
4.5 As the fire becomes established close the Primary/
Thermostat* air control (multifuel versions only) and control
the burn rate using the Airwash control only.
4.6 To burn wood efficiently it is best to allow a bed of ash to
build-up on the grate, or the base of the stove, and control
the combustion using the Airwash control only.
4.7 Before re-fuelling the stove it is advisable to first rake the
embers evenly over the firebed then open the Airwash
control fully for a few minutes, to establish a glowing bed
before adding new logs.
4.8 Allow the new logs to burn at high output for a few minutes
before adjusting the burn rate with the Airwash control,
to the desired setting. It is best to refuel little and often to
maintain clean and efficient burning.

OPERATING INSTRUCTIONS
4.9 The ideal control settings to suit the particular installation
and personal preferences will be established by experience
in using the stove.
4.10 Do not load fuel higher than the log guard. It is not
recommended to load large amounts of logs and burn with
the Airwash control on low settings for long periods of
time. This will reduce the effectiveness of the glass cleaning
effect of the airwash and will cause a large build-up of tars
and creosotes in the stove and flue system.
4.11 We would recommend that the stove be burnt at high
output for at least 30 minutes each day when it is in use.
This will help reduce the build-up of tars and creosotes
within the stove and flue system.
4.12 Do not burn construction timber, painted, impregnated /
treated wood or manufactured board products.
* The optional Thermostatic Primary air control will adjust
the air flow to the fire to maintain a constant temperature.
5. BURNING SOLID FUEL
(Multi-fuel stoves only)
5.1 Open the Airwash control to approximately 50% and
Primary/Thermostat* air control fully.
fuel. Allow the new fuel to burn at high output for a few
minutes before adjusting the burn rate with the Primary/
Thermostat* air control to the desired setting. It is best
to refuel little and often to maintain clean and efficient
burning.
5.9 The ideal control settings to suit the particular installation
and personal preferences will be established by experience
in using the stove. It is not recommmended to load large
amounts of fuel and burn with the Primary/Thermostat*
Air Control on low settings for long periods of time as this
will reduce the effectiveness off the glass cleaning effect of
the airwash. Also this will help reduce the build-up of tar
and creosotes within the stove and flue system.
5.10 We would recommend that the stove be burnt at high
output for at least 30 minutes each day when it is in use.
This will help reduce the build-up of tars and creosotes
within the stove and flue system.
5.11 Burn only anthracite or manufactured smokeless fuels,
suitable for use in closed appliances.
5.12 Do not burn bituminous coal, ‘petro-coke’ or other
petroleum based fuels, as this will invalidate the product
guarantee.
* The optional Thermostatic Primary air control will adjust
the air flow to the fire to maintain a constant temperature.
5.2 Place some pieces of firelighter or dry crumpled paper on
the grate and cover with some small pieces of dry kindling
wood. Light the paper or firelighters.
5.3 To avoid the build-up of condensation on the door glass
it is advisable to leave the door slightly open as the fire
establishes, and the glass warms.
5.4 As the fire becomes established add pieces of solid fuel and
fully close the door. Do not initially add too much fuel as
this may smother the fire. Do not leave the stove with the
door open as this could over-fire the stove and cause
permanent damage.
5.5 As the fire becomes established reduce the Airwash air
control to approximately 25% and control the burn rate
using the Primary/Thermostat* air control only.
5.6 To burn solid fuel efficiently it is best to control the
combustion using the Primary/Thermostat* air control
only.
5.7 Before re-fuelling the stove it is advisable to de-ash the
firebed, using the riddling grate system. This is completed as
follows:-
Fixed Grate
Use a suitable poker.
Riddling Grate
Move the Riddling Lever (Top right at the back) from side to
side, using the removable tool provided.
6. OVER-FIRING
6.1 Do not use the appliance at maximum output for prolonged
periods of time, or over-fill the firebox with fuel, as this
could result in over-firing. If the connecting fluepipe,
appliance flue collar or top plate glow red with heat the
appliance is being over-fired and the air controls should be
closed to reduce the output.
6.2 Do not load fuel higher than the log guard at the front of
the stove.
6.3 If a chimney fire occurs shut all air controls immediately to
close the appliance down, and evacuate all persons from
the building before calling the fire brigade. Do not re-enter
the building until it is confirmed safe to do so.
6.4 Following a chimney fire do not use the appliance until
it is inspected, by a HETAS (GB only)/INFO (Eire only)
registered installer, to confirm that the appliance is safe
to use, or make any repairs required before re-use. Only
genuine Stovax replacement parts are to be used to keep
your appliance in safe and efficient working order.
6.5 After any chimney fire it is recommended that the chimney
system be inspected and swept by a NACS registered
(UK only) chimney sweep, to confirm that the system is
structurally sound and free from any obstructions before
re-use.
5.8 Open the Primary/Thermostat* air control fully for a few
minutes, to establish a glowing bed before adding new
6
OPERATING INSTRUCTIONS
7. ASH REMOVAL (Multi-fuel stoves)
7.1 The burning of any fuel will produce ash, which will have
to be removed after a period of use. This time will depend
on the fuel used. Before removing the ash from the stove it
is advisable to let the fire burn down to a low level, or even
go out completely. The ashpan can then be removed using
gloved hands, after opening the main firedoors.
7.2 As heat can remain in the ash for a long period after use
care must be taken when removing and carrying the full
ashpan. We suggest that the ashpan be carried using gloved
hands, or the ash is placed directly in to a Stovax Ash
Caddy (Stovax Part No. 4227).
7.3 Do not place ash in a bin made from plastic or any other
combustible material.
8. ASH REMOVAL (Wood-burning stoves)
8.1 When burning wood the amount of ash will be smaller and
may only need removal once every week. To do this, allow
the fire to burn out and cool. Open the main door, then
after removing the log retainer scoop out the ash with a
suitable shovel. It is best to leave a layer of ash in the stove
to form a bed for the new fire.
8.2 Do not place ash in a bin made from plastic or any other
combustible material.
9.2 Fuel Quality (Solid Fuel)
Use only recommended solid fuels, which are approved for
use with closed appliances. Symptoms of poor performance
related to unsuitable fuels include:
• Difficulty getting a fire going and keeping it burning well
• Smoky fires with little flame
• Dirty glass
• Dirty firebricks
• Short life span for grate, baffles and internal firebricks
• Permanent staining of glass
9.3 Backpuffing
This is caused by a lack of combustion air entering the
firebox causing combustion gases to build up in the firebox
and periodically ignite as small explosions, causing smoke to
puff out of the appliance air inlets and other openings. The
problem will often occur if the air controls are shut soon
after adding new fuel to a very hot fire. To stop backpuffing
occurring open the air controls to increase the combustion
air and increase the burning rate.
9.4 Flue Draught
The chimney has two main functions, which are, to safely
remove the smoke, gases and fumes from the house, and to
provide a sufficient amount of draught (suction) in the stove
to ensure that the fire is kept burning. Draught is caused by
the rising hot air in the chimney when the stove is lit.
Symptoms of poor performance related to flue draught
include:
9. BURNING PERFORMANCE
9.1 Fuel Quality (Wood)
Use only seasoned wood with a moisture content of
less than 20%. Well seasoned logs should have the bark
beginning to lift and peel away, along with deep cracks
radiating from the centre of the log. Logs should feel lighter
than fresh cut wood of a similar size and sound hollow
when struck against each other. Logs should not feel damp
to the touch, have any visible moisture oozing from them or
moss and fungal growths on them.
Symptoms of poor performance related to wet woods
include:
• Difficulty getting a fire going and keeping it burning well,
• Smoky fires with little flame,
• Dirty glass,
• Dirty firebricks,
• Rapid creosote build-up in the chimney,
• Low heat output,
• Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney.
To help avoid large build-ups of tars and creosote within
the stove and the flue system, it is recommended to burn
at high output for at least 30 minutes each day. The use of
Stovax Protector chimney cleaner will also help to reduce
this problem.
• Excessive fuel consumption (high flue draught)
• Poor burning control, overheating (high flue draught)
• Wind noise from air controls (high flue draught)
• Difficulty getting a fire going and keeping it burning well
(low flue draught)
• Low heat output (low flue draught)
• Smoke entering room when doors opened (low flue
draught)
The construction, position, size and height of the chimney
are all factors that affect the performance of the flue
draught.
Other factors that can effect the flue draught include:
• Trees or other buildings nearby causing turbulence
• High and gusty winds
• Outside temperature
• Outside weather conditions
• Incorrect additional ventilation to building
• Blocked flue / chimney
For advice on the correction of persistent flue problems
consult a qualified solid fuel heating engineer before
continuing to use the stove.
9.5 Weather conditions
The weather conditions outside the building could have an
effect on the burning performance of the stove. These could
include:
7
OPERATING INSTRUCTIONS
Windy days - Smoking from the appliance. This could
be caused by turbulent airflow around chimney terminal,
possibly caused by the position of other buildings or
obstacles nearby. This problem is, also, sometimes
associated with oversize chimneys, which may even have
downdraught problems on calm days. If smoking is a
common problem on windy days make a note of the wind
strength and direction before consulting your appliance
installer, who will advise you on possible solutions to the
problem, after visiting the installation.
Damp / Rainy days – These sometimes result in problems
when lighting and maintaining the fire, due to the lower
flue temperatures and smaller difference between indoor
and outdoor temperatures reducing the flue draught. Also,
rain water running down the inside of the chimney reducing
the flue temperatures. To help with this problem care must
be taken to use good quality kindling wood, when starting
the fire, and running the stove at a higher heat setting than
normal for a period after start-up to fully heat the chimney.
It could be possible to fit a rain cowl to the chimney to
reduce this problem. Your appliance installer should advise
you on possible solutions.
If the stove emits smoke into the room continuously close
the air controls and allow the stove to go out, and ventilate
the room to clear the fumes.
Do not re-light the appliance until the cause of the
problem is identified and rectified.
10.2 Stove glass cracking:
Please ensure when replacing the glass in your stove that
you do not over tighten the screws on the glass clips as this
will cause stress in the glass and with the intense heating
and cooling of burning your stove it may well cause the
glass to crack.
10.3 Stove is producing tar:
You can recognise this from the following traits:
Very strong pungent smell shortly after the stove is lit and
as the stove heats up, glass blackening and, possibly, can be
seen as a thick, brown and sticky material oozing from your
stove pipe joints.
This is caused by burning damp wood and burning your
stove at too low a temperature. To resolve this only use well
seasoned wood and ensure your stove is operating in the
ideal temperature range. Tar is a major cause of chimney
fires - if you experience problems with tar build up, please
consult a chimney sweep before continued use of your
stove.
Ideal working temperature range is 130°C and 240°C
(270°F – 465°F). If you fail to close down your primary air
control once the stove has heated up to this range you may
cause your stove to overfire and the temperature to exceed
the ideal range. Overfiring can cause permanent damage to
your stove and will invalidate your warranty.
10. TROUBLESHOOTING
10.1 Stove glass blackening:
This occurs as a result of four possible causes:
1. Incorrect use of airwash – See the detailed operating
instructions Sections 4 and 5 page 5 and 6 which show the
correct use of the combustion air controls.
2. Burning unseasoned wood – See page 7 (section 9.1) for
more information on how to identify when your wood is
ready for burning. Properly seasoned logs will have been
kept for a minimum of a year but are best burnt at 2 years.
3. The stove being burned at too low a temperature - A
good working temperature is 300-500° F (120 – 250° C).
A stove pipe thermometer will help identify this problem.
(Stovax part no 3046). Burning your wood stove with
the airwash control fully open for a period of around
20 minutes ought to cure this. This might be caused by
damping your stove down overnight.
4. Problems with your flue – in particular insufficient air
pull. If your flue is not doing its job efficiently this can
cause blackening of the glass. A flue which is too short,
experiences a downdraft, needs lining or has too many
bends can promote blackening. If you suspect your flue may
be contributing to the blackening of your stove glass you
should contact the installer or a flue specialist.
11. SEASONAL USE
11.1 If the stove is not to be used during the warmer periods of
the year it is recommended to clean and service the stove,
see Maintenance and Servicing section, page 18.
11.2 The air controls should be set in the 50% open position to
keep the appliance ventilated, and stop the build-up of any
moisture inside.
11.3 Before re-lighting the stove remove the baffles, clear any
debris that may have accumulated, and check the flue is
clear of any blockages.
Heavy tar deposits should be removed using Stovax Glass
Cleaner (Stovax Part. 4103 See section 2 page 18).
