Full Running at
optimum efficiency
Wood burns best on a bed of ash (approx. 25mm (1") deep).
Rake the embers evenly over the firebed and open the
Airwash Control fully for a few minutes before re-fuelling.
5.2
Do not refuel when a large amount of flames are in the
firebox as this could cause smoke or flames to spill
into the room.
5.3
Close the doors immediately after refuelling.
5.4
Burn new logs at a high temperature for a few minutes
before adjusting the Airwash Control. Refuel little and often
for clean, efficient burning. More Airwash will increase the
heat output, burn fuel more quickly and will help keep the
glass clean.
Log Guard
— Close the door and follow the instructions for Running
the Appliance.
Small amounts of Primary Air can sometimes help to
maintain a hot fuel bed.
NOTE: It is recommended to run the Stockton with
the doors shut as this will produce the best working
efficiency.
4.7
This appliance is designed to be used with the doors
shut. However it can be operated with the doors fully
open, using the purpose designed sparkguard* from
Stovax, if fitted to a chimney with a better than average
flue pull.
Note: This will reduce the efficiency of the appliance.
Depending on the strength of the flue pull the Secondary
Air Control should be adjusted so that air from the air inlets
ignite unburnt smoke and flames are visible, but not so
strong that flames reach the glass.
5.5
Do not burn large amounts of fuel with the Airwash
Control closed for long periods of time. This reduces the
glass cleaning effect of the Airwash and causes tars and
creosotes to build-up in the appliance and flue system.
5.6
When in use, burning the appliance at a high temperature
for a short period reduces tars and creosotes.
DO NOT OPERATE THE APPLIANCE WITH THE PRIMARY
AIR CONTROL OPEN OR AIRWASH ON BOOST FOR
LONG PERIODS OF TIME AS THIS COULD CAUSE OVERFIRING AND MAY CAUSE PERMANENT DAMAGE.
Please Note: A replacement Drop In front for the appliance
is supplied with the Sparkguard. It is essential to fit this to
ensure safe operation.

Experience establishes settings to suit personal preference.
A bright and clean firebox indicates the appliance is burning
well.
Smoke Control version
5.8
These appliances have been independently tested to PD6434
and have been exempt from the controls that generally apply
in smoke control areas hence are considered suitable for use
in Smoke Control Area when burning wood and ONLY when
fitted with the relevant Smoke Control kit detailed below.
See Section 15 - Optional Extras.
Contact your retailer for more information.
To burn wood and smokeless fuels efficiently in a

5.12 To burn solid fuel efficiently it is best to control the burn rate
using the Primary air control only.
Burning Solid Fuel
Open the Primary Air Control fully to establish a glowing
bed before adding new fuel.
5.14 Add the correct amount of fuel, see Section 3.
5.15 Close the doors immediately after refuelling.
Burn new fuel at a high temperature for a few minutes before
adjusting the Primary Air Control to the desired setting.
Refuel little and often for clean, efficient burning.
When burning solid fuel more primary air will increase the
heat output and burn the fuel more quickly.
A small amount of Airwash can sometimes help to keep the
glass clean but will reduce efficiency.
Always have the Secondary Air Control shut when burning
solid fuel to ensure the maximum efficiency from the appliance.
5.16 Experience establishes settings to suit personal preference.
5.17 Do not burn large amounts of fuel with the Primary Air
Control on a low combustion setting for long periods of
time. This reduces the glass cleaning effect of the Airwash
and causes tars and creosotes to build-up in the appliance
and flue system.
5.18 When in use, burning the appliance at a high temperature
for a short period reduces tars and creosotes.
DO NOT OPERATE THE APPLIANCE WITH THE PRIMARY
AIR CONTROL OPEN OR AIRWASH ON BOOST FOR
LONG PERIODS OF TIME AS THIS COULD CAUSE
OVER-FIRING AND MAY CAUSE PERMANENT DAMAGE.
5.10 To burn wood and smokeless fuels a cast iron multi-fuel kit
must be fitted.
5.19 Only anthracite or smokeless fuels suitable for use in
closed appliances must be burned in this appliance.
5.20 Do not burn bituminous coal, ‘petro-coke’ or other
petroleum based fuels as this invalidates the product
guarantee.
Only for use with recommended fuels,
(see User Instructions, Section 3). 5.11 Allow the fire to become established before adding the solid
fuel, see section 4.
— Set air controls, See Diagram 11.

5.22 If there is still burning fuel in the firebox, Stovax do not
recommend shutting down the air controls completely
unless there is a chimney fire in progress (see section 9
for advice). Closing the controls during the burning process
will cause poor combustion and could lead to a build up of
gasses that could ignite dangerously.
5.23 Always have enough air entering the stove to maintain
some flame within the firebox.
5.24 If it is necessary to shut down the appliance then run on
a high setting until all of the fuel has been burnt before
closing the air controls.
User Instructions/Care & Maintenance
6. Extended Burning
6.1
It is possible to get the appliance to burn for extended
periods of time. In order to do this:
— De-ash prior to final refuelling.
7.3
Open the door.
Using gloves, carefully remove ashpan using tool supplied,
see Diagram 13. Ensure the tool is fully engaged before
operation. Practise this technique before hand with a cold
ashpan.
— Burn new fuel at a high temperature for a few minutes before adjusting the Primary Air Control.
Warning: Ash can remain hot long after appliance has
been in use.
13
— Set air controls to low combustion settings.
This will gradually blacken the glass but it will clear when operated at a high temperature for a short period.
7. Ash Removal
Do not allow ash to build up as it may cause damage
and adversely effect the performance of the appliance.
Warning: Ash can remain hot long after appliance has
been in use.
7.1

Care & Maintenance
9. Chimney Fire
9.1
If a chimney fire occurs:
— Shut all air controls immediately.
— Evacuate the building.
— Call the fire brigade.
— Do not re-enter the building until it is confirmed safe.
9.2
Do not use the appliance after a chimney fire until:
a) It has been inspected by a registered installer*, confirming the appliance is safe to use.
b) The chimney system has been inspected and swept by a
chimney sweep, confirming the system is structurally sound
and free from obstruction*.
c) It is repaired as required before re-use. Use only genuine Stovax replacement parts to keep your appliance in safe,
efficient working order.
10. General Cleaning
10.1 Clean and inspect the appliance regularly, especially in
periods of heavy use. Regular cleaning and maintenance
will help give many years of safe use.
11. Cleaning Glass
11.1 Keep the glass clean with correct use of the Airwash system
and good quality fuel. Use the boost setting to clear any
build up.
11.2 Sometimes additional cleaning may be required.
Before undertaking this operation allow appliance to cool
fully. Do not clean hot glass.
11.3 On appliances with printed glass do not use cleaning
agents that have a high alkaline or acidic content, for
example Stovax Gel Cleaner, these are aggressive
cleaning agents designed to be used with heavily
stained clear glass. On printed glass surfaces, use
Stovax Glass Cleaner (Stovax No.4103) which is better
formulated for this application.
11.4 Before applying a cleaning agent remove any dust and
loose soot with a damp cloth.
11.5 Use an appropriate glass cleaner. Apply the cleaning fluid to
a cloth before rubbing onto the glass.
Apply carefully and do not apply excessively. Try to prevent
any run off which could soak into the rope seals around the
edge of the glass.
Soot can also contain acidic particles that can cause
corrosive damage to printed glass.
11.6 Remove dirt with a moist cloth and buff dry.
Remove the ash completely.
(See User Instructions, Section 7).
11.7 Some types of wood and solid fuel can cause a white
residue to form on the glass.
If this occurs it should be cleaned off at least once a
week during periods of heavy usage.
If the liquid cleaning agents recommended do not
remove this residue use a dry cleaning pad which will
help remove these white marks.
10.4 Check internal components for damage and for obvious
build up of soot, ash or debris above the flue baffle(s) (these
can be found in the upper part of the firebox). Use a torch if
necessary.
11.8 Before relighting the appliance ensure the glass is fully dried.
If the rope seal has absorbed excess cleaning agent it
is advisable to replace the rope as soon as possible to
preserve the printed finish of the glass.
10.2 Allow appliance to cool thoroughly to avoid risk of
burns.
10.3 Clean regularly, according to level of use.
10.5 If there are any signs of a build up of debris above the flue
baffle(s) either:
— Arrange for the chimney to be swept (see Care &
Maintenance Instructions, Section 12).
— Remove the baffles and clear the debris
(see Pre-Installation Instructions, Section 4).
10.6 To refresh painted finishes a touch up spray is available.
Contact your Stovax retailer quoting the serial number found
on the appliance date badge.
Do not use aerosol sprays near an operating appliance.
Do not use abrasive cleaner or cleaning pads.
10.7 Check that the door shuts properly and creates an effective
seal. Leaking door seals prevent the appliance working
properly.
*Registered on the Competent Persons Scheme (GB
only) see page 35/ INFO (Republic of Ireland).
10
12. Chimney Sweeping
12.1 To maintain safe and efficient use of the appliance, the
chimney/flue must be inspected and swept at least once a
year by a qualified chimney sweep*.
If the appliance is used continuously throughout the year,
or it is used to burn wood, more frequent sweeping is
recommended.
The best time to have the chimney swept is at the start of
the heating season.
12.2 The chimney, any connecting flue pipe and the appliance
flue ways, if incorporated, must be regularly cleaned.
12.3 Ensure adequate access for cleaning where it is not
possible to sweep through the chimney.
12.4 If the chimney is believed to have previously served an open
fire it must be swept a second time within a month of regular
use after installation.

THE APPLIANCE
Tar coming from flue joints
Strong pungent smell after the appliance is lit
Glass blackening
The flue system has two main functions:
FLUES
- To safely remove the smoke, fumes and combustion gases from the building.
- To provide a sufficient amount of flue draught (suction) in the appliance to ensure the fire keeps burning.
The flue draught is caused by rising hot gases when the appliance is lit.
Tar and creosote are a major cause of chimney fires. If the appliance experiences problems with tar build up consult a chimney
sweep before continued use of the appliance.
For advice on the correction of persistent flue problems consult a qualified heating engineer before continuing to use the
appliance.

Clearances to flue outlet
The weather surface is the building external surface, such as its roof tiles or external walls.
A flat roof has a pitch less than 10°.
The clearance given for A or B, as appropriate, will also apply.
A vertical flue fixed to an outside wall should be treated as equivalent to an inside flue emerging at the nearest edge of the roof.

2. Flue or Chimney
2.1
The flue or chimney system must be in good condition.
It must be inspected by a competent person and passed for
use with the appliance before installation.
Products of combustion entering the room can cause
serious health risks.
2.2
The following must be checked:
— The construction of the masonry chimneys, flue block chimneys and connecting flue pipe system must meet the
requirements of the Building Regulations†.
— A flexible flue liner system can be used if certified for use with solid fuel systems and installation complies with manufacturer’s instructions and Building Regulations.
The flue liner must be replaced when an appliance is replaced, unless proven to be recently installed and in good condition.
2.3
Do not connect to systems containing large voids or spaces
over 230mm square.
2.4
Suitable access must be provided to enable the collection
and removal of debris.
2.5
The flue must be swept and inspected when the appliance
is installed.
Flue Draught
The flue draught must be checked with all windows and
doors closed and any extraction fans in this, or adjoining
rooms, running at maximum speed (see Installation
Checklist for ventilation requirements).
Twin Wall Flue System
If this appliance is to be used in conjunction with a twin
wall flue system then Stovax recommend the use of
their Professional XQ range. Details of this product are
available from your Stovax retailer.
— If it is necessary to fit a register plate it must conform to
the Building Regulations†.
— The minimum height of the flue or chimney must be 4.5m
from the hearth to the top of the flue, with no horizontal
sections and a maximum of 4 bends. Bends must have
angles of less than 45 degrees from the vertical.
In the U.K:
—There should be at least 600mm of vertical flue pipe
above the appliance before any bends are introduced.
**This should be done by a NACS registered (UK
— Ensure the connecting flue pipe is kept a suitable distance from any combustible material and does not form
part of the supporting structure of the building.
† Building Regulations Document J
— The installer must ensure the flue pipe diameter is not
less than the diameter of the outlet of the appliance and
does not narrow to less than the size of the outlet at any
point in the system.
— Make provision to remove the appliance without the need
to dismantle the chimney.
Flue Plate:
Where a hearth, fireplace, flue or chimney is
provided or extended (including cases where a
flue is provided as part of refurbishment work),
information essential to the correct appliance and
use of these should be permanently posted in the
building, to meet Requirement J4 of the Building
Regulations (England and Wales), F3.12 (Scotland).
— Any existing flue must be confirmed as suitable
for the new intended use as defined in the Building Regulations.
— The flue or chimney systems must be inspected and swept to confirm the system is structurally sound and free from obstructions.
— If the chimney is believed to have previously served an
open fire it must be swept a second time within a month of
regular use after installation to clear any soot falls that may
have occurred due to difference in combustion levels.
— The flue exit from the building must comply with local building control rules†.
—Chimney heights and/or separations may need to
be increased in particular cases where wind exposure,
surrounding tall buildings, high trees or high ground could
have adverse effects on flue draught.
— Do not connect or share the flue or chimney system with
another heating appliance.

Ventilation - Technical Appendix
3. Ventilation
3.1
Many older buildings are sufficiently ventilated by natural
leakage of air to provide suitable air supply for an appliance
of 5kW output or less.
Modern building techniques have reduced the amount of air
that leaks in or out of a house. A modern construction with
an air tightness of less than 5m3 per hour per m2 requires
an air vent for ALL solid fuel appliances including those with
a rated heat output of less than 5kW.
NOTE: The air leakage of a modern house is tested at the
completion of construction and a certificate issued confirming
this.
3.2
This appliance requires a constant supply of air to maintain
proper combustion and effective flue performance.
3.3
An inadequate air supply can result in poor combustion and
smoke entering the room which is potentially dangerous.
3.4
This supply of air can come from either:
— Purpose provided ventilation.
4.1
— Some Stovax appliances can also be fitted with an
optional outdoor air kit which allows air to be drawn in from
the outside.
3.5
4. Minimum Dimensions - Hearth
The amount of air required must comply with local building
regulations and the rules in force.
The appliance must stand on a non-combustible
constructional hearth which is at least 125mm thick with the
minimum dimensions as shown in diagram.
As this appliance can be installed in an elevated setting it is
recommended to increase the 225mm hearth depth to safely
contain any falling logs or embers. The higher the appliance
is installed the deeper the hearth should be to protect the
floor.
3.6
If spillage is detected during commissioning then there may
be insufficient natural ventilation and an additional air supply
will be necessary.
4.2
The building must have a suitable load-bearing capacity for
the hearth and appliance. Consult a structural engineer for
advice before proceeding.
3.7
Permanent air vents should be non-adjustable and
positioned where they are unlikely to be become blocked.
4.3
3.8
If vents open into adjoining rooms or spaces there must be
an air vent of at least the same size direct to the outside.
When fitting into an existing hearth check that the appliance
complies with current construction regulations and is at least
the minimum sizes shown.
4.4
3.9
Site the vents where cold draught is unlikely to cause
discomfort. This can be avoided by placing vents near
ceilings or close to the appliance (See diagram).
If there is no existing fireplace or chimney it is possible to
construct a suitable non-combustible housing and hearth
setting. The flue must be installed in accordance with all
local and national regulations and current rules in force.
4.5
Check if adding a new chimney to your property requires
planning permission.
4.6
Some houses are built using a timber frame construction
with high levels of thermal insulation. Isolate the appliance
from combustible materials, and provide sufficient ventilation
to maintain the heating efficiency.
3.10 Extractor fans or cooker hoods must not be placed in the
same room or space as this can cause the appliance to emit
fumes into the room.
3.11 Increase air supply provisions where a room contains
multiple appliances.
3.12 If any checks reveal problems do not proceed with the
fitting of the appliance until they have been rectified.
34
Technical Appendix
5. Fitting Appliances On A Boat
5.1
If an appliance is to be fitted in a boat it must be done in
accordance with the latest edition of BS 8511 (Code of
Practice for the Installation of Solid Fuel Heating Appliances
on Boats). The Code covers the design, installation
and operation of solid fuel heating appliances that are
suitable for fitting into inland waterway boats, and gives
guidance on product selection, design considerations,
installation requirements, inspection and testing, as well as
maintenance and safe use tips.
5.2
Consideration should also be given to the requirements
of the Boat Safety Scheme (BSS) to ensure the boat's
insurance remains valid.
5.3
The appliance should only be installed by a competent
person with experience of the latest edition of BS 8511 and
the Boat Safety Scheme (BSS).
5.4
Secure the product to a suitably constructed noncombustible hearth.
5.5
All open flued appliances can be affected by temporary
atmospheric conditions which may allow fumes to enter the
boat. An electronic carbon monoxide detector conforming
to the latest edition of BSEN50292 must be fitted and
maintained.
5.6
Failure to safely install the appliance could endanger the
boat and persons on board.
