Your Yeoman retailer provides you with a Two Year Warranty
for your new stove. However, this specifically excludes
naturally wearing parts or ‘consumables’ such glass, firebricks
and rope seal and the use of non-authorized fuel such as
petro-cokes. Furthermore, for the warranty to be valid,
your stove must have been installed in accordance with the
manufacturer’s instructions and the second year’s warranty is
dependent on the appliance being serviced 12 months after
installation by a HETAS or other similarly qualified engineer.
They also provide a Five Year Casting Warranty for the carcass
of all cast iron stoves and the cast iron door of steel stoves.
Again, this excludes naturally wearing cast parts such as grate,
dampers, log retainers and baffles.

HEATING SYSTEM CONTROLS
CONTROLS, GENERAL
1.18 The controls fitted to the system will provide two
functions:
—To control the comfort level in the house.
—To maintain safety in the event of misuse or
mechanical failure.
COMFORT CONTROLS
1.19 A programmable timer switches the pump on when heat
is required and off when it is not.
The timer, when combined with a room thermostat and
/ or thermostatic radiator valves, enhances the comfort
levels in the house.
Some room thermostats combine the function with
the timer and can be programmed to reduce the room
temperature rather than turning the system off. This is
effective in not allowing rooms to become too cold and
speeding up recovery time.
1.20 The hot water cylinder can also be fitted with a
thermostatic valve which turns off the flow when the
cylinder has reached the desired temperature, but the
heat leak radiator will have to be bigger to cope with the
extra load when the tank is isolated.

SAFETY CONTROLS
1.21 A high limit thermostat is fitted to the gravity flow pipe
set at 80˚C. This thermostat should be connected to the
pump so that the pump is turned on if the temperature
exceeds 80˚C. This will prevent accidental boiling in the
gravity circuit.
1.22 It is also recommended to fit a low limit thermostat on
the central heating return set at 45˚C. This thermostat will
turn the pump off if the return temperature falls below
45C. This will prevent corrosion and condensation within
the stove.
NOTE – Further information on solid fuel central heating
systems can be found in the HETAS engineers training
manual.

USER INSTRUCTIONS
WARNING
Properly installed, operated and maintained this
appliance will not emit fumes into the room.
Occasional fumes from de-ashing and refuelling may occur.
Persistent fume emission is potentially dangerous and
must not be tolerated.
If fume emission does persist:
—Open doors and windows to ventilate the room.
—Allow fire to burn out and safely dispose of fuel from the
appliance.
—Check for chimney blockage and clean if required.
—Do not attempt to relight until the cause of the emission
has been identified and corrected. If necessary seek
expert advice.
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.
2.6 Precautions must be taken to ensure that this build up of
condensate does not overflow from the appliance onto
any surrounding fabric of the room e.g. carpets.
NOTE - THIS CONDENSATION IS NORMAL DURING
FILLING AND DOES NOT INDICATE A FAULTY OR
LEAKING STOVE.
NORMAL RUNNING
2.7 During normal running this condensation should be
minimal if the system is fitted with the low limit thermostat
as detailed in 1.22 (above). This low limit thermostat
prevents the system pump from running until the stove has
reached temperature.
SEASONAL USE
2.8 If this appliance is unused for lengthy periods of
time it should be periodically checked to ensure that
condensation is not building up within the stove.
NOTE – THIS CONDENSATION IS NORMAL AND DOES
NOT INDICATE A FAULTY OR LEAKING STOVE.
If the stove is going to be unused for very long periods of
time it is recommended to drain the system.
3. RECOMMENDED FUELS
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 temperature 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.
CONDENSATION
CAUTION WHEN FILLING
2.4 When filling the boiler with water for the first time,
the cold water entering the water jacket can cause
condensation to form on the surfaces of the appliance
(inside and outside).
2.5 In certain conditions this condensation could result in a
considerable amount of water, in some cases enough to fill
the bottom of the appliance. This could be even worse if
the house has recently been re-decorated, wet plastered
or any other work has been undertaken which could result
in high humidity.
3.1 Wood Logs

USER INSTRUCTIONS
5. RUNNING THE APPLIANCE
BURNING WOOD:
5.1 This appliance gives out its heat in two ways:
—Directly into the room in which it is fitted through
convection and radiation.
—Hot water to heat radiators and domestic hot water.
The output to hot water varies depending on how
quickly the fuel is being burnt. Fore more detail see the
graph on page 13.
5.2 Only for use with recommended fuels, see Section 3 for
full details.
—Close the Primary Air control and use the Airwash to
control the burn rate when the appliance is at optimum
operating temperature (see Diagrams 7 & 8).
7
—Rake the embers evenly over the firebed and open the
Airwash control fully for a few minutes before
re-fuelling.
Do not refuel when a large amount of flames are
present in the firebox as this could cause smoke or
flames to spill into the room.
Close the doors immediately after refuelling.
5.3 Burn new logs at a high temperature for a few minutes
before adjusting the Airwash control. Refuel little and
often for clean, efficient burning.
Do not load above the log guard or base of baffle.
5.4 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.
5.5 When in use, running the appliance at a high temperature
for a short period reduces tars and creosotes.
5.6 Experience establishes settings to suit personal preference.
Do not burn construction timber, painted,
impregnated / treated wood, manufactured board
products or pallet wood.
5.6 BURNING SOLID FUEL
To burn smokeless fuels a cast iron multi-fuel grate must
be fitted.
Only for use with recommended fuels (see User
Instructions, Section 3).
5.7 Set air controls as shown in Diagram 9.

USER INSTRUCTIONS
5.8 De-ash the firebed before re-fuelling (see User
Instructions, Section 7).
Open the Primary Air Control fully to establish a glowing
bed before adding new fuel.
Burn new fuel at a high temperature (see Diagram 7) for a
few minutes before adjusting the Primary Air Control to
the desired setting.
Refuel little and often for clean, efficient burning.
5.9 Experience establishes settings to suit personal preference.
5.10 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.
5.11 When in use, burning the appliance at a high temperature
for a short period reduces tars and creosotes.
5.12 Only anthracite or smokeless fuels suitable for use in
closed appliances must be burned in this appliance.
5.13 Do not burn bituminous coal, ‘petro-coke’ or other
petroleum based fuels as this invalidates the product
guarantee.
5.14 Do not load fuel above the log guard and the base of
the baffle at the back of the firebox (see Diagram 5).
REFUELLING
5.15 De-ash the fire bed before refuelling, see Ash Removal
—Open the Primary air control fully to establish a
glowing bed before adding new fuel.
—Do not refuel when a large amount of flame is
present in the firebox as this could cause smoke or
flames to spill into the room.
—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.
5.16 Do not re-fuel the stove above the level of the log guard
or the base of the baffle.
THERMOSTAT OPERATION
6. BURNING TIPS
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 and fungal growths.
Symptoms related to wet wood:
—Difficulty starting and keeping a fire burning well.
—Smoke and small flames.
—Dirty glass.
—Rapid creosote build-up in the chimney.
—Low heat output.
—Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney.
Burn at a high temperature for a short period each day
to avoid large build-ups of tars and creosote within the
appliance and the flue system.
Use Stovax Protector chimney cleaner to reduce this
problem.
6.2 Fuel Quality (Solid Fuel)
Use recommended solid fuels approved for use with closed
appliances.
Symptoms related to unsuitable fuels include:
—Difficulty starting and keeping a fire burning well.
—Smoke and small flames.
—Dirty glass and/or fire bricks.
—Short life span for Grate and Baffle.
—Permanent staining of glass.
6.3 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.
6.4 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.
5.17 This appliance can be fitted with a thermostat kit to
control the temperature of the boiler. See the instructions
included in the kit for operation details.
In the U.K.
* Registered on the Competent Persons Scheme (GB only)
see page 35 / INFO (Republic of Ireland).
** This should be done by a HETAS registered chimney
sweep, see page 35, who will issue you with a certificate.

USER INSTRUCTIONS
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, 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
all affect the performance of the flue draught.
Other factors effecting the flue draught include:
—Trees or other buildings nearby causing turbulence.
—Outside temperature.
—Outside weather conditions.
—Incorrect additional ventilation to building.
—Blocked flue / chimney.
For advice on the correction of persistent flue problems

USER INSTRUCTIONS
11. CHIMNEY FIRE
11.1 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.
11.2 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 Yeoman replacement parts to keep your appliance
in safe, efficient working order.
12. GENERAL CLEANING
12.1 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 7).
Check the internal components for damage. Do not use
the appliance if any parts are broken or damaged. Replace
damaged parts with genuine Yeoman 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:
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.
13. CLEANING GLASS

—Use a soft cloth and Stovax Glass Cleaner.
13.2 Before re-lighting the appliance dry the glass fully.
13.3 Do not use abrasive cleaner or cleaning pads.
14. CHIMNEY SWEEPING
14.1 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 or smokeless fuel, more frequent
sweeping is recommended.
The best time to have the chimney swept is at the start of
the heating season.
The above applies even if burning smokeless fuels.
14.2 The chimney, any connecting flue pipe and the appliance
flue ways, if incorporated, must be regularly cleaned.
14.3 Ensure adequate access for cleaning where it is not possible
to sweep through the chimney.
14.4 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.
—Arrange for the chimney to be swept (see User
Instructions, Section 14).
—Remove the baffle and clear the debris (see Installation
Instructions, Section 3).
