IMPORTANT OPERATION / MAINTENANCE NOTES
Now that your Stanley Solid Fuel Stove is installed and no doubt you are looking forward to many comforts it
will provide, we would like to give you some tips on how to get the best results from your stove.
1. We would like if you could take some time to read the operating instructions/hints, which we are
confident, will be of great benefit to you.
2. Do not burn fuel with a high moisture content, such as a damp peat or unseasoned timber. This will
only result in a build up of tar in the stove and in the chimney.
3. IMPORTANT: The first few fires should be relatively small to permit the refractory to set properly
and season the stove. During these firings it is recommended to ventilate the room as an
unpleasant (not toxic) odour may be emitted as the paint is completing curement.
4. Inspect the flue-ways of the stove weekly and ensure that there are no blockages. Check flue
ways before lighting especially after a shut down period. Please see chimney cleaning section.
5. Before loading fresh fuel into the firebox, riddle fully to remove all ashes. This will allow better and
cleaner burning. See Re-Fuelling section.
6. Never allow a build up of ashes in the ash pan, as this will cause the grate to burn out prematurely.
Empty the ashpan when refuelling.
7. Avoid slow burning of damp or unseasoned fuel as this will result in tarring flue ways and chim-
ney i.e. peat or timber.
8. Allow adequate air ventilation to ensure plenty of air for combustion.
9. Do not burn rubbish/household plastic.
10. Clean the chimney at least twice a year.
11. Burning soft fuels such as timber and peat will stain the glass. Regular cleaning will prevent
permanent staining. Clean with soapy water when cool.
12. Keep all combustible materials a safe distance away from unit, please see section for clearances
to combustibles.
13. Never use aerosol spray near the appliance when it is in operation.
14. For safety reasons never leave children or the elderly unaccompanied while stove is in use. Use a
fire guard.
15. Avoid contact with the appliance when in use as stove reaches very high operating temperatures.
16. This appliance should be regularly maintained by a competent service engineer.

ing the installation. Failure to do so may result in
damage to persons and property. Consult your local
Municipal office and your insurance representative
to determine what regulations are in force. Save
these instructions for future reference.
Please note that it is a legal requirement under
England & Wales Building Regulations that the
installation of the stove is either carried out under
Local Authority Building Control approval or is
installed by a Competent Person registered with a
Government approved Competent Persons
Scheme. HETAS Ltd operate such a scheme and a
listing of their Registered Competent Persons can
be found on their website at www.hetas.co.uk.
Special care must be taken when installing the stove
such that the requirements of the Health & Safety at
Work Act are met.
Handling
Adequate facilities must be available for loading,
unloading and site handling.
Fire Cement
Some types of fire cement are caustic and should
not be allowed to come into contact with the skin. In
case of contact with the skin wash immediately with
plenty of water.
Asbestos
This stove contains no asbestos. If there is a possi-
bility of disturbing any asbestos in the course of
installation then please seek specialist guidance and
use appropriate protective equipment.
Metal Parts
When installing or servicing this stove care should
be taken to avoid the possibility of personal injury.
“IMPORTANT WARNING”
This stove must not be installed into a chimney that
serves any other heating appliance.
The complete installation must be done in accor-
dance with current Standards and Local Codes. It
should be noted that the requirements and these
publications may be superseded during the life of
this manual.
Please refer to the current standards, BS EN 15287-
1:2007 Design, Installation and Commissioning of

ELECTRICAL CONNECTIONS
The installation of any electrical services during the
installation of this stove must be carried out by a
registered competent electrician and in accordance
with the requirements of the latest issue of BS 7671.

FLUES
Flues should be vertical wherever possible and
where a bend is necessary, it should not make an
angle of more than 45owith the vertical. Horizontal
flue runs should be avoided in order to minimise flue
resistance and to make sweeping easier it is recom-
mended to use 2 x 45obends rather than a 90o
bend.
CHIMNEY
Do not connect to a chimney serving another
appliance.
The stove is a radiant room heater and must be con-
nected to a chimney of the proper size and type.
The chimney must have a cross-sectional area of at
least 30 square inches 19350sq. mm or a diameter
of at least 6” (150mm). It is best to connect to a
chimney of the same size, as connection to a larger
size may result in a somewhat less draught.
A flue that has proved to be unsatisfactory, particu-
larly with regard to down draught should not be used
for venting this appliance until it has been examined
and any faults corrected. An existing masonry chim-
ney should be inspected and if necessary repaired
by a competent mason or relined using an approved
lining system.
The stove must be connected to a chimney with a
minimum continuous draught of 0.06” w.g. Poor
draught conditions will result in poor performance.
All register plates, restrictor plates, damper etc.,
which could obstruct the flue at a future date should
be removed before connecting this appliance.
If connecting to an existing chimney with a flue
diameter of more that 8” it is recommend to line the
flue using a suitable stainless steel flue liner.
Where a masonry chimney is not available a propri-
etary type of 6”/150mm - twin wall, fully insulated
pipe may be used.
A chimney / flue termination must be located to min-
imise wind effects, a basic guide is that the distance
from the termination to the roof should be at be at
least 2300mm when measured horizontally and at
least 1000mm when measured vertically, (see
Fig.2). In circumstances where there are adjoining
buildings/ structures/ roof openings there are addi-
tional requirements, please refer to building regula-
tions part J.

Step 10
Measure the distance to the flue outlet of the stove
and compare to the chimney, decide on best orien-
tation of the offset adaptor.
Step 11
Push the offset adaptor into position and make a
seal using approved fire cement between the adap-
tor and the clay liner. The seal should be tapered to
allow any condensation that may occur in the
chimney flow back into the flue. See Fig.7.

stove as shown in Fig.8. Then lift the baffle up into
the top of the stove while maintaining it at an angle.
Twist the baffle so that it is above the support rail.
Then lift the back edge and slide the baffle back to
the rear of the stove so that the tab on the baffle
drops into the corresponding slot on the support rail.
Step 12
Measure and cut the extension pipe at the straight
end to the required dimension using the guide collar
provided.
Step 13
Lay the flue gasket onto the flue spigot and then fit
the extension pipe to the spigot using the grub
screws provided and seal using fire cement.
Step 14

FRONT REMOVAL & FITTING
If necessary the front casting can be removed to
improve access at the side of the product when
making the connections. First remove the screws
fixing the door to the hinges while supporting the
door and ensuring the surface does not get dam-
aged (extra care is needed on enamel finish).
Then remove the 4 front fixing screws (see Fig.10)
which will allow the front casting and the surround-
ing shroud to be removed from the boiler by sliding
it to the left to clear the secondary air control rod and
then pulling it forward, in some circumstances it may
be necessary to unscrew the secondary air control
rod before removing the front.
Make the required connections and replace the front
in reverse order making sure that the front seals fully
to the boiler.
Step 17
Plumb the boiler - See Plumbing Section. Check all
connections for leakage before insulating the boiler

DOWN DRAUGHTS
However well designed constructed and positioned,
the satisfactory performance of the flue can be
adversely affected by down draught caused by near-
by hills, adjacent tall buildings or trees. These can
deflect wind to blow directly down the flue or create
a zone of low pressure over the terminal.
A suitable terminal or cowl will usually effectively
combat direct down blow but no cowl is likely to pre-
vent down draught due to a low pressure zone.
(See Fig.11).
VENTILATION & COMBUSTION AIR REQUIRE-
MENTS
It is imperative that there is sufficient air supply to
the stove in order to support correct combustion.
The air supply to this appliance must comply with
current Building Regulations Part J, Heat Providing
Appliances. If another appliance is fitted in an adja-
cent room it will be necessary to calculate an addi-
tional air supply.
The minimum effective air requirement for this appli-
ance is 66cm2. When calculating combustion air
requirements for this appliance use the following
equation: 550mm2per each kW of rated output
above 5 kW should be provided, where a flue
draught stabiliser is used the total free area shall be
increased by 300mm2for each kW of rated output.
If there is another appliance using air fitted in the
same or adjacent room, it will be necessary to pro-
vide an additional air supply.
Note:
There must not be an extractor fan fitted in the same
room as the stove as this can cause the stove to
emit smoke and fumes into the room.
All materials used in the manufacture of air vents
should be such that the vent is dimensionally stable,
corrosion resistant, and no provision for closure.
The effective free area of any vent should be ascer-
tained before installation. The effect of any grills
should be allowed for when determining the effective
free area of any vent.
Air vents should be positioned so that they are not
liable to blockage.
Air vents direct to the outside of the building should
be located so that any air current produced will not
pass through normally occupied areas of the room.
An air vent outside the building should not be locat-
ed less than the dimensions specified within the
Building Regulations and B.S. 8303: Part 1 from any
part of any flue terminal. These air vents must also
be satisfactorily fire proofed as per Building
Regulations and B.S. 8303: Part 1.
Air vents in internal walls should not communicate
with bedrooms, bedsits, toilets, bathrooms or rooms
containing a shower.
Air vents traversing cavity walls should include a
continuous duct across the cavity. The duct should
be installed in such a manner as not to impair the
weather resistance of the cavity.

11
Joints between air vents and outside walls should be
sealed to prevent the ingress of moisture. Existing
air vents should be of the correct size and unob-
structed for the appliance in use.
If there is an extraction fan fitted in adjacent rooms
where this appliance is fitted, additional air vents
may be required to alleviate the possibility of
spillage of products of combustion from the appli-
ance/flue while the fan is in operation. Refer to B.S.
8303 Part 1.
Where such an installation exists, a test for spillage
should be made with the fan or fans and other appli-
ances using air in operation at full rate, (i.e.extrac-
tion fans, tumble dryers) with all external doors and
windows closed.
If spillage occurs following the above operation, an
additional air vent of sufficient size to prevent this
occurrence should be installed.
Especially Airtight Properties:-
If the stove is being fitted in a property where the
design air permeability is less than 5m3/ (h.m2)
(normally newer properties built from 2006), then a
permanent ventilation must be fitted to provide
550mm2of ventilation for each kW of rated output.
If a draught stabiliser is also fitted then the require-
ment is 850mm2per kW of rated output.
EXTERNAL DUCTED AIR
An outside air kit complete with primary air supply
can be ducted from outside and is available to order
for connection to the stove.
It is recommended to bring the air supply for the
stove into the house using a 4” plastic pipe. Where
the pipe meets the outside wall make sure a vent
cover is fitted properly to ensure no rodents can
enter via the vent pipe.
The vent pipe should be located to prevent the
ingress of moisture and in a location where it will not
get blocked with leaves or any other debris. As wind
effects can create suction and pressure zones of
opposite sides of the dwelling it is recommended to
run the air vent from opposite poles (North, South,
East & West) of the dwelling and tee off for the air
supply to the stove. This should negate the effect
of suction and pressure zones. See Fig. 12
‘HETAS product approval covers this appliance
when installed in accordance with the manufactur-
er’s instructions and relevant standards. As there is
currently no standard for Ducted Combustion Air
Supply this does not fall within the remit for HETAS
product approval. Responsibility for the specification
of this and for appropriate manufacturer’s instruc-
tions is carried by the appliance manufacturer, as
allowed for under the Building Regulations.’
Note: When Installing
outside air pipe adhere
to ‘Clearance to
Combustible’ Section.

HEAT RECOVERY VENTILATION
Where a stove is to be installed in a dwelling with
Heat Recovery Ventilation (HRV) a number of pre-
cautionary measures must be undertaken:
Where the product is to be installed with a
Mechanical ventilation, the stove must be connected
to an external air supply, The ductwork for the exter-
nal air supply must be no longer than 6 metres and
the air inlet terminal to the ductwork must have a
cross sectional area of at least 80cm2.
LOCATION
There are several conditions to be considered in
selecting a location for your Cara + Insert Stove.
a. Position in the area to be heated, central
locations are usually best.
b. Allowances for proper clearances to
combustibles.
c. Allowances for proper clearances for mainte-
nance work.
Clearances to Combustibles
This appliance must be installed in a recess, the
recess should not contain any combustible material.
Wood battens and plaster board should not be used
within the clearance to combustibles. The minimum
clearance to combustibles required is as follows:
To the Top 200mm (8”)
To the Front 550mm (22”)
From the Sides 150mm (6”)
To Combustible Flooring 350mm (14”)
Fig 13
Fig 14
If the mantlepiece protrudes further than 100mm
from the fireplace, then it will be necessary to have
further clearance to the top of the stove. The dis-
tance the mantle protrudes past the 100mm should
be added to the clearance.
For example, if the mantle protrudes 200mm, the
clearance to the mantle should be 300mm. (See
Figs 13 & 14).
12

FLOOR PROTECTION
It is recommended that the appliance is installed on
a solid, level, concrete base of non combustible
hearth conforming to the current Building
Regulations must extend 350mm in front of the unit
and 350mm from the sides of the front edge. This
will provide protection from sparks and embers
which may fall out when stoking on refuelling.
PLUMBING
PIPE THERMOSTAT
The fitting of a pipe thermostat to the flow pipe is
essential in order to activate the water circulation
pump when the water reaches the selected tem-
perature.
When the water temperature falls below the select-
ed temperature the pipe thermostat will cut off the
water circulation pump in order to allow the boiler
to recover.
Fig 15
REGULATIONS
The plumbing must be in accordance with all rele-
vant regulations and practices. It must include a
gravity circuit with expansion pipe, open to the
atmosphere. The central heating will normally be
pump-driven as with other types of boilers.
GRAVITY CIRCUIT
The gravity circuit consists of the domestic hot water
tank of 135 litres indirect cylinder, fixed in an upright
position, recommended for hot water storage and it
should be connected to the boiler by 28mm diame-
ter flow and return piping. The pipes should not
exceed 7.8 meters (25ft) in length and cylinder and
pipework should be fully lagged. The shorter the run
of pipe work the more effective the water heating.
There must be no gate valves on this circuit and it
must have an expansion pipe exhausting to atmos-
phere. Cylinder and pipe work should be lagged to
minimise heat loss.
Fig. 16 illustrates the basic principal of water heat-
ing systems and must not be regarded as a work-
ing drawing.
13
Fig.16

14
INJECTOR TEE
Where the gravity and central heating circuits join
together to return to the stove we recommend the
use of an injector tee connection, situated as close
to the unit as possible. This type of tee encourages
a stable flow of hot water through both circuits and
helps to prevent priority being given to the stronger
flow, which is most commonly the pumped central
heating circuit. This way, there will be no shortage
of hot water to the taps when the heating is on.
Where the appliance is to be interlinked with anoth-
er boiler it will be necessary to use a double feed
indirect cylinder in accordance with BS 1566. (See
Fig 17 for an illustration)
WATER CIRCUIT TEMPERATURE
The return water temperature should be maintained
at not less than 40°C so as to avoid condensation on
the boiler and return piping. Fitting a pipe thermo-
stat to the flow pipe of the gravity circuit and wiring it
into the pump control will ensure rapid circulation of
the hot water.
In some circumstances it may be possible to over-
heat the appliance and the water inside will boil.
This will be evident by the sound of a knocking noise
coming from the appliance and pipes around the
house. If this occurs close off all air controls and
manually start the central heating pump if fitted.
One radiator on the heating circuit should be uncon-
trolled to act as a heat leak in the event that the
appliance overheats and has nowhere to discharge
a build up of hot water should the heating circuit be
satisfied. Be aware that steam and boiling water will
be expended from any open vent from the heating
system probably in the roof space at the expansion
tank.
In the unlikely event that the appliance is not oper-
ating in freezing conditions the water must be
drained from the boiler to prevent frost damage.

WARNING: DO NOT OBSTRUCT PRIMARY AIR SUPPLY TO THE STOVE
Note: Dimensions stated are in millimetres unless otherwise stated and may be subject to a slight +/- variation.
COMMISSIONING AND HANDOVER
On completion of the installation allow a suitable
period of time for any fire cement and mortar to dry
out, when a small fire may be lit and checked to
ensure the smoke and fumes are taken from the
stove up the chimney and emitted safely to the
atmosphere. Do not run at full output for at least
24 hours.
Ensure that the operating instructions for the stove
are left with the customer. Ensure to advise the cus-
tomer on the correct use of the appliance with the
fuels likely to be used on the stove and warn them to
use only the recommended fuels for the stove.
Advise the user what to do should smoke or fumes
be emitted from the stove. The customer should be
warned to use a fireguard to BS 8423:2010 in the
presence of children, aged and/or infirm persons.
OPERATION
Check that all dampers and catches are operating
correctly and ensure that all flue connections are
thoroughly sealed.
15
AIR CONTROLS
The stove has two independent air controls:
1. The thermostat knob (see fig. 20) which
controls the primary air. Rotate clockwise to
open and anticlockwise to close.
2. The secondary air control which is located
on the LHS. Pull to open and push to
close (see fig. 21).

In the event where a stove is fitted to a central heat-
ing system which is undersized in relation to the
nominal heat output to boiler then the stove will
operate satisfactorily but will be unable to achieve
the nominal heat output to room as the thermostat-
ic damper will shut off the air supply to prevent an
overheat situation in the boiler.
For example:- Where a stove provides 2kW to the
room and 8kW to the boiler and if the thermostatic
damper shuts down the air supply to provide 4kW to
the boiler, then the heat to room will decrease pro-
portionally to 1kW.
RECOMMENDED FUELS
All fuels should be stored under cover and kept
as dry as possible prior to use.
This appliance has been tested using seasoned
wood logs and manufactured briquetted smokeless
fuel (Ancit) for closed appliances, sized between
20g and 140g. Other fuels are commercially avail-
able and may give similar results. Wood logs up to
380mm long are suitable. All fuels should be stored
under cover and kept as dry as possible prior to use.
Do not use fuels with a Petro-coke ingredient as this
may cause the grate to overheat, causing damage.
Reduced outputs will result when fuels of lower
calorific values are used. Never use gasoline or
gasoline type lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or freshen up a fire in
this heater. Keep all such liquid well away from the
heater at all times. Operate the stove only with the
fuelling door closed except for re-fuelling.
This stove has obtained HETAS Ltd approval for
burning natural and manufactured smokeless fuels
only as detailed in recommended fuels below.
HETAS Approval does not cover the use of other
fuels either alone or mixed with the recommended
fuels listed, nor does it cover instructions for the use
of other fuels.
NOTE:-
The controls may become hot when the stove is in
operation, use tools or glove provided to adjust the
controller when the stove is hot.
A boiler model stove will provide heat into the boiler
and also to the room in which it is situated. The heat
to room is in a fixed relationship with the heat to the
boiler.
The heat to the boiler is controlled by the air supply
to the stove which is required to have a thermosta-
tic damper for safety reasons. When the tempera-
ture of the water in the boiler exceeds 55 ˚C the ther-
mostatic damper will begin to shut off the air supply,
should the water temperature continue to rise the
thermostatic damper will continue to close and if the
water temperature reaches 85˚C the thermostatic
damper closes the primary air supply fully.

LIGHTING
Before lighting the stove check with the installer that
the installation work and commissioning checks
described previously have been carried out correct-
ly and that the chimney has been swept clean, is
sound and free from any obstructions. As part of the
stoves commissioning and handover the installer
should demonstrate how to operate the stove cor-
rectly.
LIGHTING THE STOVE
1. Open the firebox door and remove all debris
from the grate and ashpan.
2. Open the primary air control by turning it clock
wise fully (see Fig. 21).
3. Set the secondary air slider to the required posi-
tion depending on the fuel being burned i.e.
open when burning wood and closed when
burning coal/ anthracite (see Figure 22).
4. Place pieces of paper & kindling on the top of
the grate and add a small quantity of fuel. Light
the fire and close the firebox door.
5. When a good fire is established, open the fire
door and load the fuel as required.
6. Adjust the primary air control & the secondary
air slider as required depending on the fuel type
being used & the heat output as required (see
table below). Both controls should be adjusted
in conjunction with each other to get the appro-
priate burn rate with exact settings on each con-
trol depending on the draught conditions of the
chimney to which the unit is connected.

Coal Adjust for Desired Heat Output Fully Closed
Turf/ Wood Fully Closed Slightly Open
WARNING: DO NOT LEAVE BOTH AIR CONTROLS FULLY OPEN AS THIS CAN CAUSE THE STOVE TO
OVERHEAT, DAMAGING THE INTERNAL COMPONENTS.
RE-FUELLING
When refuelling with manufactured smokeless fuel
riddle the fire by connecting the grate operating tool
onto the rocker connection located at the bottom
front of the stove. Then gently pull and push the
rocker arm until all dead ash has fallen through into
the ashpan. Before opening the door, open the pri-
mary air by turning the knob clockwise, as this will
help to eliminate any smoke or fly ash resident in the
combustion chamber. Add fuel to fire, taking care
not to overfill higher than the front firebars. Close fire
door and re-set control knob to required setting. Do
not operate this appliance with the fire door open.
(See Fig.22)
When burning wood the requirement to riddle the
fire is much less. Do not riddle the fire with the pri-
mary air open but fully open the secondary air con-
trol instead. Remember to reset the controls after
refuelling.

REMEMBER COAL GASES ARE TOXIC
SLOW BURNING
To achieve slow burning when burning wood close
the secondary air slide and open a few millimetres.
Slow burning will cause the window glass to blacken
and should not be used for a long period as it will
leave sooty deposits in the flueways. Opening the
air slide will increase the heat output and will clear
the glass.
To obtain slow burning when burning coal, close the
secondary air fully and partially open the primary air
control.
DE-ASHING
Never allow the ashpan to over fill as it will cause
damage to the grate. Empty the ashpan before
lighting. Always ensure that ashes have thoroughly
cooled before removing the ashpan. Open the fire
door and remove ashpan using the operating tool.
Close the fire door. When the ash is disposed of,
replace the empty ashpan. Do not leave the fire
unattended with the fire door open, even for a
minute.
DISPOSAL OF ASHES
Your stove is provided with a stainless steel ashpan.
This ashpan should be emptied every day.
If ashes are allowed to build to grate level you could
damage the firebars by overheating. We recom-
mend that you remove ashes after you have riddled
the fire when the stove is thoroughly cooled.
Ashes should be placed in a metal or other non-
combustible container with a tight fitting lid. The
closed container of ashes should be placed on a
non-combustible material, pending final disposal. If
ashes are buried in soil, or otherwise dumped they
should be retained in the closed container until they
are thoroughly cooled.
Open the firedoor and remove the ashpan using the
tool provided, see Fig 23. Close the firedoor. When
the ash is disposed of replace the ashpan.

MONTHLY MAINTENANCE
Cleaning Stove Flue Pathways
It is recommended that the flue pathways in the
stove are cleaned on a monthly basis (or less
depending on the soot build-up created by the fuel
being used) and the chimney cleaned annually. To
access the chimney pathways, use the following
procedure:
1. The bottom baffle should be removed from
the stove through the fire door opening and
cleaned thoroughly. For ease of removing
the baffle from the firebox, remove the fire
bars. Remove the bottom baffle by lifting up
the front of the baffle and sliding it forward
(see Fig. 24).
2. When it is clear of the support rib, lift one
side of the baffle which will allow the oppo-
site side to drop down into the centre of the
stove (see Fig. 25). Remove the baffle from
the stove by holding it at an angle allowing
for it to pass through the opening on the front
casting.

GRATE REMOVAL & CLEANING
Over time fuel deposits, clinker & ash can lodge
between the grate and grate support which can
cause difficulties when moving the grate during de-
ashing. To help reduce this occurrence, it is recom-
mended that the grate is cleaned on a monthly basis
when undertaking the general cleaning of the flue
pathways using the following procedure:
1. The grates are removed, by removing the
ashpan and then lifting the grate up from
underneath on the RHS to release it from
the grate linkage (see Fig. 26). Replace
the ashpan and clean all ash from the grate
insert & underside of the grate.
2. When replacing the grate, the grate linkage
will need to be lifted and for ease of fit, the
front grate should be replaced first. When
both grates have been fitted, pull the grate
pull rod to check that the grate is riddling.
