IMPORTANT NOTICE
Your new Bosca Wood Burning appliance is perhaps the
most advanced design of modern stoves. Owning such a
appliance shows appreciation for exceptional quality.
If your appliance is installed correctly, it will give you many
years of excellent service for which it was designed. This
appliance must be installed by a HETAS registered installer
(GB only).
Please read your manual thoroughly, it’s purpose is to
familiarise you with your stove, and give guidelines for it’s
installation, operation and maintenance. If after reading
this manual you need further information, please do not

WARNING
All types of heating appliance can be potentially dangerous.
Correct installation and operating procedures must be
observed when fitting this stove. Some parts of your
appliance are protected on their surface with heat proof
paint. When the appliance is first used it is normal for it to
emit some light smoke, with an unpleasant smell. Though
unpleasant, this is nontoxic and is produced only whilst the
paint fully cures. We recommend that you ventilate the
room until this disappears.

INSTALLATION INSTRUCTIONS
3. COMMISSIONING
3.1 Before lighting the Bosca stove, check the following items:
a) Fit of internal parts (firegrate, firebricks, baffles, and fuel
retainer).
b) Door alignment, seals and catch operation.
c) Operation of air controls.
3.2 If there are any problems with the fit or operation of any of
these items, this should be corrected before continuing
with the commissioning of the Bosca stove.
3.3 Carry out a final smoke draw test, by first warming the flue
with a blowlamp, or similar, for about 10 minutes. Then
place a smoke pellet on the centre of the grate, with the air
controls open, and close the door. Smoke should now be
drawn up the flue and be seen to exit from the flue
terminal. This test should be completed with all doors and
windows in the room where the appliance is fitted closed.
Should this test fail, the suitability of the flue system and
ventilation should be re-checked.
3.4 Light the appliance and gently allow the temperature to
increase slowly to operating levels. Check that no
combustion products are entering the room. When the
appliance has reached a steady operating condition open
the main firedoor and carry out a spillage test with a smoke
match or pellet around the door opening.
3.5 If excessive spillage does occur, allow the appliance to cool
and re-check the suitability of the flue system and
ventilation.
3.6 Explain the safe operation of the appliance and the use of
the controls to the user, along with the need to only use
suitable fuels. Also explain the cleaning and routine
maintenance requirements.
3.7 Explain the requirements to use a suitable fireguard when
children, elderly or infirm persons may be near the
appliance.
3.8 Record Retailer/supplier details and installer details in
user instructions on page 4.

4.3 Light the paper or firelighters and close the upper door of
the appliance.
All open flued appliances can be affected by temporary
atmospheric conditions which may allow fumes to enter
the house. Because of this it is recommended that an
electronic carbon monoxide detector conforming to
BSEN50291 be fitted and maintained.
4.4 Open the Ashpan door for approximately 3 minutes or until
the kindling is lit.
2. USING THE Appliance FOR
THE FIRST TIME
2.1
To allow the appliance to settle and fixing glues and paint
to fully cure operate the appliance at a low output for first
few days.
2.2
Do not touch the paint during the first period of use.
2.3
During this time the appliance may give off some
unpleasant odours. Keep the room well ventilated to avoid
a build-up of fumes

operating INSTRUCTIONS
4.12 Do not burn painted or impregnated wood,
manufactured board products, pallet wood or scrap
timber.
4.5 Open the upper door to load larger pieces of firewood,
placing the smaller logs on the lit kindling. Allow space
between the stacked logs for the air to circulate. Logs
stacked too tightly together will starve the fire of oxygen.
5. Refuelling

4.9 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 Primary Air control only.
4.10 It is not recommended to load large amounts of logs and
burn with the Primary Air control on low settings for long
periods of time as this will reduce the effectiveness of the
glass cleaning effect of the Primary Air. Also this will cause
large a build-up of tars and creosotes in the appliance and
flue system.
5.5
4.11 We would recommend that the appliance 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 appliance and flue system.

6. BURNING WOOD
6.1
Fuel Quality (Wood)
Use wood with a moisture content of less than 20%.
Seasoned logs have the bark beginning to lift and peel away
and cracks radiating from the centre. They feel lighter than
fresh cut wood of a similar size and sound hollow when
struck against each other. Logs should not feel damp or
have moss or fungal growths.
Symptoms related to wet wood:
—Difficulty starting and keeping a fire burning well.
—Smoke and small flames.
—Dirty glass and/or Firebricks.
—Rapid creosote build-up in the chimney.
—Low heat output.
—Short burn times, excessive fuel consumption and blue/
6.5
Weather conditions
The weather conditions outside the building can effect the
burning performance of the appliance. These could include:
Windy days
Smoky appliance
Burn at a high temperature for a short period each day to
avoid large build-ups of tars and creosotes within the
appliance and the flue system.
Buildings/obstacles
cause turbulent air
around chimney
Calm days
Oversized chimney
Smoky appliance
Damp / Rainy days

chimney
Lighting and
burning problems
6.3
Flue Draught
The chimney has two main functions:
1) To safely remove the smoke, gases and fumes from the
house.
2) To provide a sufficient amount of draught (suction) in the
appliance ensuring the fire keeps burning.
Draught is caused by the rising hot air in the chimney when
the appliance is lit.
Symptoms of poor performance related to flue draught
include:
—Excessive fuel consumption (high flue draught).
—Poor burning control and/or 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 are opened (low flue
draught).
For advice on the correction of persistent flue problems
consult a qualified heating engineer before continuing to
use the appliance.
Effect
Air inlets puffing smoke
Combustion gases can build up in the firebox and ignite as
small explosions, causing smoke to puff out of the air inlets
and other openings. This occurs if the air controls are shut
soon after adding new fuel to a very hot fire. Stop by
opening the air controls to increase combustion air and
burning rate.
Problem
6.2
Other factors effecting the flue draught include:
Weather Conditions
Use Stovax Protector chimney cleaner to reduce this
problem.
—Nearby trees or buildings causing turbulence.
—Outside temperature.
—Outside weather conditions.
—Incorrect additional ventilation to building.
—Blocked flue or chimney.
grey smoke from the chimney.
The construction, position, size and height of the chimney
all affect the performance of the flue draught.
20
—Use good quality kindling wood to start the fire.
—Burn initially at a high temperature for a short period.
—Fit a rain cowl to the chimney.
—Close the air controls and allow the appliance to go out.
—Ventilate the room to clear the fumes.
Do not re-light the appliance until the problem is solved.
To reduce these problems:
Your installer should advise you on possible solutions.
If the appliance emits smoke into the room continuously:
operating INSTRUCTIONS
6. 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.
6.1
Open Doors.
—Do not re-enter the building until it is confirmed safe.
8.2
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 Bosca replacement parts to keep your appliance in
safe, efficient working order.
9. GENERAL CLEANING
9.1
Clean and inspect the appliance regularly, especially in
periods of heavy use. Regular cleaning and maintenance
will help give many years of safe use.
Allow appliance to cool thoroughly to avoid risk of burns.
Clean regularly, according to level of use.
Remove the ash completely (see User Instructions, Section

baffles and log guard). Do not use the appliance if any parts
are broken or damaged. Replace damaged parts with
genuine Stovax replacement parts to keep the appliance in
safe, efficient working order.
Check 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.
If there are any signs of a build up of debris above the flue
baffle(s) either:
Leave a layer of ash to start the new fire on. Wood burns
best on a bed of ash (approx. 1" deep).
Remove ash with a small shovel and place into a Stovax Ash
Caddy (Stovax Part No. 4227) or other suitable container.
Do not place hot ash in any container made from plastic or
any other combustible material.
De-ash at least once a week.
—Arrange for the chimney to be swept
—Remove the baffles and clear the debris (see Installation
7. OVER FIRING
7.1
7.2
Instructions, Section 2).
Do not over-fill with fuel or run at high temperatures for
long periods or over-firing can occur. If the flue pipe, flue
collar or top plate glow red the appliance is over-firing.
Close the air controls to reduce the temperature.
Wipe dry with a soft clean cloth be fore relighting. Always
dry appliance to avoid rust.
Do not use abrasive cleaner or cleaning pads.
Over-firing can cause permanent damage to the
appliance.
Check that the door shuts properly and creates an effective
seal. Leaking door seals prevent the appliance working
properly.
Do not use aerosol sprays near an operating appliance.

10.2 Before re-lighting the appliance dry the glass fully.
10.3 Do not use abrasive cleaner or cleaning pads.
11. CHIMNEY SWEEPING
11.1 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.
13. SEASONAL USE
13.1 Clean and service the appliance if it is not used during the
warmer periods of the year, as detailed in the Maintenance
and Servicing section.
13.2 Set the air control to 50% to keep the appliance ventilated
and stop the build-up of any moisture inside.

flue ways, if incorporated, must be regularly cleaned.
13.3 Before re-lighting the appliance:
11.3 Ensure adequate access for cleaning where it is not possible
to sweep through the chimney.
11.4 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.
—Remove the baffle(s).
—Clear any debris that may have accumulated.
—Check the flue is clear of any blockages.
14. TROUBLESHOOTING
14.1 Appliance glass blackening
This has four possible causes:
22
1.
Incorrect use of Air Control
See Instructions, Sections 1, 4 and 5 for the correct use of
the air controls.
2.
Burning unseasoned wood
See Instructions, Section 3 to identify when wood is ready
for burning.
3.
Appliance operated at too low a temperature
An appliance pipe thermometer can identify this problem
(Stovax part no 3046). The ideal working temperature
range is 130°C - 250°C (270°F - 480°F). Failing to close
down the Primary Air Control once the appliance has
heated up to this range may cause the appliance to exceed
operating INSTRUCTIONS
4.
the ideal temperature range and to over-fire. Over-firing can
cause permanent damage to the appliance and invalidates
your warranty. Burn with the Air Control fully open for
approximately 20 minutes to cure this.
The problem may be caused by damping down the
appliance during periods of extended burning.
Problems with the flue, in particular insufficient air pull. If
the flue is not working efficiently the glass can blacken. A
flue which has too much downdraft may be too short,
needs lining, or has too many bends. This can also cause
blackening of the appliance glass. Contact the installer or a
flue specialist for advice.
14.2 Glass cracking
Do not over tighten the screws on the glass clips when
replacing the glass. This causes stress and the intense
temperature changes can cause the glass to crack. For
replacement glass contact your local Bosca Retailer.
14.3 Appliance is producing tar
This can be identified by:
—A very strong pungent smell shortly after the appliance is
—Glass blackening.
—Thick, brown, sticky tar oozing from the pipe joints.
lit and heats up.
This is caused by burning damp wood and running the
appliance at too low a temperature.
Use well seasoned wood and operate the appliance within
the ideal temperature range.
Tar is 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.
14.6 In the unlikely event of a problem that cannot be solved
by these tips contact your installer or Retailer for help.
