2. Component Identification and Assembly
Your stove comes packed in a protective plywood crate. Carefully remove the straps and lift
off the top and upper crate. Remove any plastic packaging, open the door and remove all the
contents. See List of Components section (above) and check contents carefully.
2.1 To remove the baffle plate, first remove the fuel retainer by lifting it up and out the front of
the stove. Carefully remove the two side liners and the rear liner. Handle & store very carefully to one side where they will not get broken.
2.2 Now the baffle plate can be removed by lifting off its supports and bringing out through the
firebox door opening.
2.3 It is sometimes useful to remove the door at this stage by opening and lifting up to slide the
hinge pins out.
2.4 Screw the air wash control pin into the air wash slider control and secure using the locknut
provided.
2.5 If installing within a smokeless zone, fit the smoke control zone air limiter bracket according
to its instructions.
2.6 Proceed to install the stove according to these instructions and current installation
standards or HETAS requirements. The internal parts of the stove can be re-assembled as
the reverse of the previous removal instructions.

3.0 Installation Instructions
3.1. WARNINGS AND IMPORTANT SAFETY INFORMATION
3.1.1 READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION!
These instructions cover the basic principles to ensure satisfactory installation of the stove, although detail may
need slight modification to suit particular local site conditions. In all cases the installation must comply with
current local regulations including Building Regulations, Local Authority Byelaws and other specifications or
regulations including UK or EU standards referred to as they affect the installation of the stove. Approved
Document J is particularly important for England and Wales and can be downloaded for no cost at:
Also of importance are Approved Documents (A.D.) L1 A and B conservation of fuel and power. The Domestic
Heating Compliance Guide will also be found useful.
In addition to these instructions the requirements of BS 8303 and BS EN 15287 must be fulfilled. The installat ion
is a notifiable building works as defined in the building regulations and that it is a legal requirement under
England and Wales Building Regulations that the installation 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 .
3.1.2 Important Chimney Warning
This stove must notbe installed into a shared chimney that serves any other heating appliance.
3.1.3 Extractor Fan Warning
There must not be an extractor fan fitted in the same room as the stove as this can cause the
stove to emit fumes into the room. If unavoidable the appliance must be checked with
Approved Document A.D. 1.21 and necessary action taken. HETAS can provide guidance of a
pressure test procedure to check safe operation of the stove and flue.
3.1.4 Cleaning and Chimney Sweeping
The appliance, flue & chimney must be cleaned and checked internally and externally
regularly in use and especially after a period of disuse (e.g. after summer). Remove the side
liners and lift down the baffle at least weekly to check for build up of soot or debris on the top
from the flue pipe. Remove the baffle and check the flue spigot and connector is fully clear at
regular intervals. The chimney and flue connector must be swept at least annually, more often
when used with sooty fuels or damp wood. The chimney or flue can usually be swept through
the appliance. A wire centred sweeps brush with guide wheel is recommended. Any loose,
broken or leaking joints or flue ways MUST be repaired immediately.
3.1.5 Fuels
Only use recommended fuels which are seasoned (or kiln dried) wood logs or smokeless
briquetted fuels. The appliance can be damaged by burning petroleum coke, liquid fuels or
general rubbish and this will invalidate your warranty and risk your personal safety. The
appliance must not be used as a rubbish incinerator.
3.1.6 Maintenance
Annual checking and servicing of the appliance and flue by a competent engineer is
recommended.
3FGi.FPi.FXi Issue 12 10/17
3.1.7 Ventilation
Adequate ventilation is ESSENTIAL for the safe and efficient operation of any solid fuel or wood
burning appliance. Ventilation MUST be provided where required by the stove output or flue
under-performance. Keep all ventilation clear and free of blockage, including any direct outside
air connection where used. See VENTILATION in INSTALLATION INFORMATION section.
3.1.8 OVERFIRING WARNING
It is possible to over fire a stove by overloading the firebox with fuel and using too much air –
having the air controls open too wide - during the combustion cycle. This will cause overheating
and potential damage to parts such as the grate, baffle plates, firebox liners and fuel retainers.
IF ANY METAL PART OF THE STOVE GLOWS RED, INCLUDING THE BAFFLE PLATE OR FUEL
RETAINER, IMMEDIATELY REDUCE THE AIR CONTROL SETTINGS UNTIL THE OVERHEATED
PARTS OF THE STOVE COOL AGAIN. Failure to do so will damage the stove and invalidate any
warranty. Parts damaged by overheating, thermal cracking or even melting are NOT covered
by any warranty.
3.2. Health And Safety Precautions
Special care must be taken when installing this stove to meet all requirements of the Health &
Safety at Work act.
3.2.1. Handling
Adequate facilities must be available for unloading and site handling. Stoves are very heavily
built so always ask for assistance when lifting and siting them. See Technical Data for weights.
3.2.2. Fire Cement
Some types of fire cement are caustic and should not be allowed to come into contact with the
skin. In case of skin contact, wash immediately with plenty of water.
3.2.3. Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the course
of installation then please seek specialist guidance and use appropriate protective equipment.
3.2.4. Metal Parts
When installing or servicing this stove, proper care should be taken to avoid the possibility of
personal injury. Injury may be caused by component weight, sharp parts or trapping for
example and these risks should be identified and minimised.
4.0 Installation Information
4.1. Chimney/flue
The chimney height and the position of the chimney terminal should conform to Building
Regulations. Minimum chimney height is 4.5m and the recommended minimum diameter is
150mm wherever possible for safety margin and performance. The chimney must be swept
before connection to the stove. Check that the chimney is in good condition, dry and free from
cracks and obstructions. The diameter of the flue should not be less than 125mm (spigot
diameter) at any point and not greater than 200mm. If any of these requirements are not met,
the chimney should be lined by a suitable method. The chimney must be swept before
connection to the stove. When using a liner, a 5” 125mm flexible flue liner is permitted be used
on these stoves providing that the users only burns smokeless fuel or seasoned wood logs with
the air limiter fitted in in full accordance with the wood burning instructions. A 6” 150mm liner
is always better where it is possible to use one.
4FGi.FPi.FXi Issue 12 10/17
Where the chimney is believed to have previously served an open fire installation, it is possible
that the higher flue gas temperature from the stove may loosen deposits that were previously
firmly adhered, with the consequent risk of flue blockage. It is therefore recommended that the
chimney be swept a second time within a month of regular use after installation.
If you have any doubts about the suitability of your chimney, consult your local dealer or
chimney specialist. If there is no existing chimney then either a solid fuel compatible
prefabricated block chimney or a twin-walled insulated stainless steel flue to BS 4543 can be
used. These chimneys must be fitted in accordance with the manufacturer’s instructions and
Building Regulations.
4.2. Ventilation
Document J of the Building Regulations states that (except in recently built properties) purpose
provided ventilation is not required in England and Wales unless the appliance nominal rated
output is greater than 5kW. Over 5kW 5.5 cm2 of ventilation (550mm2) is required for every kW
output above 5. For example 6.5 kW requires 8.25 cm2 and 8 kW needs 16.5cm2. In any case, if
difficulty in starting the fire or any excessive fuming is experienced, ventilation must be put in
place as required to eliminate these flue problems. If a flue draught stabiliser is fitted then extra
ventilation is required. See Document J of the Building Regulations for detailed guidance
especially in new build properties where purpose provided ventilation may be required.
4.3. Flue Draught
Typically a flue draught at the flue collar of 2.2mm to a maximum 3.5mm water gauge (22 to 35
Pascals) is required for satisfactory appliance performance. This relates to 12-25 Pascals at the
higher tapping on EN13240/13229 test rigs. The flue draught should be checked under fire at
high output and, if it exceeds the recommended maximum, a draught stabiliser must be fitted
so that the rate of burning can be controlled to prevent over-firing.
4.4. Connection to the Chimney
This appliance is not suitable for use in a shared flue.
Whilst 6” 150mm diameter flue or liner is recommended wherever possible, a suitable 5”
125mm flexible flue liner is permitted be used on these stoves providing that they only burn
smokeless fuel or seasoned wood logs with the air limiter fitted in in full accordance with the
wood burning instructions.
An existing fireplace opening can be bricked up or sealed with a register plate. A short length of
suitable quality rigid flue pipe of a minimum 125mm internal diameter may then be used to
connect the stove to the chimney. This flue pipe should conform to Building Regulations. The
stove must be insulated and properly fitted into the fireplace opening by back filling with 6:1
ratio vermiculite & cement mixture using minimal water through the top of the fireplace or flue
spigot opening. The surface should be finished using 1:1:8 mix of cement, lime and sand. The
connecting pipe is fitted with the spigot pushed up from inside the stove and rotated onto its
keyhole slots to join to the pipe. If the connecting flue pipe enters the vertical flue way at any
other angle except vertically, ensure that the pipe end is no closer (along the axis direction of
the pipe) than 76mm to the side or rear chimney walls.
If necessary a hole must be opened up into the flue way above the fireplace in order to fit the
appliance to the flue correctly. Please consult HETAS for recommended fitting methods if in
doubt. It is essential that all connections between the stove and chimney-flue are sealed and
5FGi.FPi.FXi Issue 12 10/17
made airtight with sealing rope, clamping rings and/or fire cement or heat resisting cement
where required. This includes sealing any holes in the firebox top or the annulus around the flue
spigot to prevent heated convection air being drawn out of the top of the stove or liner
insulation materials from dropping through.
Both the chimney and flue pipe must be accessible for cleaning and if ANY parts of the chimney
cannot be reached through the stove (with baffle removed), a soot door must be fitted in a
suitable position to enable this to be done.
4.5. Fixing
Fix the stove to the back hearth using suitable non-combustible fixings through the base of the
outer firebox. If necessary screw the outer firebox to the back-panel by fixing the top or sides of
the firebox using suitable non-combustible fixings.
4.6. Material Clearances
4.6.1. Safety Distances from Combustible Surfaces:
Model Shelf (4”/100mm) Side surround leg (100mm) Side Full Wall
In addition it is strongly recommended that any furniture or other combustible materials are
kept at least 900mm clear from the front of the stove.
NOTE: Combustible surfaces can be protected from radiant heat from the stove by adding noncombustible heat shielding between the stove and the materials with an air gap behind it. By
doing so, safe distances may be substantially reduced in practice.
4.6.2. COMBUSTIBLE SHELVES AND BEAMS
Due to the fact that combustible shelves, timber fireplaces and beams have potentially
thousands of possible configurations in conjunction with stoves outset or inserted partially or
fully into chambers, it is not possible to give firm guidance on dimensions to these features. As a
guideline, materials that are in ‘line of sight’ to the stove are more likely to overheat due to
direct radiation from the stove body than materials that are not in ‘line of sight’ (e.g. with stove
fully inside a chamber). Materials above the stove are far more likely to overheat than materials
alongside or below. A guideline limiting temperature for solid timber (not surface finishes) is
approximately 80-85 degrees C with a normal ambient room temperature. Temperatures of
combustible materials can be substantially lowered with a simple heat shield constructed of a
non-combustible material (e.g. metal or fireproof board etc.) and a small air gap (6-12mm for
example) between the shield and combustible material.
4.6.3. Distances from NON-combustible materials:
The stove can be recessed in a suitable sized non-combustible fireplace that is just larger than
the outer firebox. To conform to building regulations the fireplace recess walls should be at
least 200mm thick or each rear leaf at least 100mm thick in the case of a cavity wall at the rear.
If these dimensions are not met further protection for any combustible materials must be
provided. The walls of the fireplace recess and the hearth must be made of non-combustible
material.
6FGi.FPi.FXi Issue 12 10/17
4.7. Hearths:
These stoves require a 125mm thick non-combustible constructional hearth beneath them to
protect the building; this can include any solid non-combustible floor. A non-combustible
superimposed hearth forming an apron of at least 225mm at the front of the stove and 150mm
on either side must also be provided. The superimposed hearth must not be less than 12mm
thick and must have a clearly defined edge (change of level) to discourage placing of any
combustible materials on or partially over it. Ensure the hearth is flat & level and the back panel
and surround are at right angles to the hearth.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the existing
construction does not meet this requirement, suitable measures (e.g. load distributing plate)
should be provided to achieve it.
4.8. Commissioning and Handover
CO Alarm: Building Regulations require that whenever a new or replacement fixed solid fuel or
wood/biomass appliance is installed in a dwelling a carbon monoxide alarm must be fitted in
the same room as the appliance. Further guidance is available in BS EN50292:2002 and from the
alarm manufacturer’s instructions. Provision of an alarm must not be considered a substitute
for either installing the appliance correctly or ensuring regular servicing and maintenance of the
appliance and chimney system.
Upon completion of the installation, allow a suitable period of time for any fire cement and
mortar to dry out. A small fire may then be lit and checked to ensure the smoke and fumes are
taken from the stove up the chimney and emitted safely to atmosphere.
Advise the customer not to run the stove at full output for at 3 – 4 days. Explain that stoves can
provide much more or less output than their rated ‘nominal’ heat outputs depending upon
fuels, fuel loads used and how they are operated.
Warn the customer that using excessive air (having the air controls open too wide for too long
with a full fuel load) can over-fire and irreparably damage the stove. Damage caused by over
firing is NOT covered by any warranty.
Left and right firebricks are provided for the FP/FGi5 Wide and FPi8 models for use when
burning smokeless fuels only – see section on solid smokeless fuel burning. They are NOT
required to be fitted for burning wood but MUST be fitted for burning smokeless fuels. Explain
this to the customer and show them how to take them in and out of the firebox.
On completion of the installation and commissioning, check all parts of the appliance are
correctly fitted and ensure that the operating instructions and operating tools (including gloves)
for the stove are left with the customer. You must be sure to advise the customer 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 on what to do should smoke or fumes be emitted into the room from the stove
– see Safety Notes section. The user should be warned that they MUST use a suitable fireguard
in the presence of children, aged and/or infirm persons.

NOTE: Refuelling intervals for testing are chosen according to the standards concerned for performance testing and are
comparative only. They do not relate directly to re-fuelling intervals that can/might/will be achieved on an installed product. Refuelling intervals of 1-1.5h for wood and 3-4+ hours for briquetted smokeless fuels would be more usual. Under normal
conditions on a low air control setting stoves should stay in overnight on suitable briquetted smokeless fuel.
8FGi.FPi.FXi Issue 12 10/17
6.0 Operating Instructions
6.1. Safety Notes for your guidance
6.1.1. FIRES CAN BE DANGEROUS – Always use a fireguard to BS 8423:2002 Fireguards
for use with solid fuel appliances in the presence of children, the elderly or the
infirm.
6.1.2. DO NOT perform modifications to the appliance as this could seriously
compromise safety in operation.
6.1.3. DO NOT OVERFIRE – it is possible to fire the stove beyond its design capacity,
this could buckle parts and damage the stove, so watch for signs of over firing – if
any part of the stove starts to glow red, including baffle plate or fuel retainer, the
fire is in an over fire situation and the controls should be adjusted accordingly.
Never leave the stove unattended for long periods without first adjusting the
controls to a reduced and safe setting – careful air supply control should be
exercised at all times.
6.1.4. WARNING – FUME EMISSION
Properly installed and operated, this appliance will not emit fumes. Occasional fumes from deashing and refuelling may occur which is not normally of serious concern. However,persistent fume emission is potentially dangerous and must not be tolerated.
If fume emission does persist, then the following immediate action should be taken: -
1. Open doors and windows to ventilate room
2. Let the fire out, or remove and safely dispose of fuel from the appliance.
3. Check for flue chimney blockage and clean if required.
4. Do not attempt to re-light the fire until the cause has been identified and corrected.
If necessary, seek professional advice from chimney or stove specialists.
Important! – Do not fit an extractor fan in the same room as this appliance.
6.1.5. IN THE EVENT OF A CHIMNEY FIRE
Raise the alarm to let others in the house know.
Call the Fire Service
Reduce the appliance burning rate by closing all air controls fully.
Move furniture and rugs away from the fireplace and remove any nearby ornaments.
Place a fireguard or spark guard in front of the stove.
Feel the chimneybreast for sign of excessive heat.
Do not relight the fire until the chimney and flue ways have been examined by a
professional.
If the wall is becoming hot, move the furniture away. Ensure that the Fire Service can gain
access to your roof space in order to check this area for signs of fire spread.
6.1.6. CO ALARMS
Your installer should have fitted a CO alarm in the same room as the appliance. If the alarm
sounds unexpectedly, follow the instructions given under “Warning Note” below.
WARNING If the CO Alarm sounds unexpectedly:-
1. Open Doors and windows to ventilate the room and then leave the premises.
2. Let the fire go out.
9FGi.FPi.FXi Issue 12 10/17
6.1.7.Warnings:
This appliance is not designed for open operation and therefore should not be operated with
the doors open.
This stove is designed to burn wood and smokeless fuels cleanly with high efficiency. However,
for this product to work properly it must be used correctly. If used correctly this stove will burn
with the very useful feature of clean glass.
It is essential that the stove has an adequate air supply for combustion and ventilation. DO NOT
block any ventilators provided. The primary, secondary and tertiary air inlets and any room
ventilation must be kept clear of obstruction.
Warning! This appliance will be very hot when in operation and due care should be taken when
operating the controls. A tool and pair of quality leather gloves are provided to assist safe
operation.
Do not use an aerosol spray on or near the stove when it is alight.
6.2. The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare the whole or part of the district of the
authority to be a smoke control area. It is an offence to emit smoke from a chimney of a
building, from a furnace or from any fixed boiler if located in a designated smoke control area. It
is also an offence to acquire an "unauthorised fuel" for use within a smoke control area unless it
is used in an "exempt" appliance ("exempted" from the controls which generally apply in the
smoke control area).
In England appliances are exempted by publication on a list by the Secretary of State in
accordance with changes made to sections 20 and 21 of the Clean Air Act 1993 by section 15 of
the Deregulation Act 2015. Similarly in Scotland appliances are exempted by publication on a list
by Scottish Ministers under section 50 of the Regulatory Reform (Scotland) Act 2014. In
Northern Ireland appliances are exempted by publication on a list by the Department of
Agriculture, Environment and Rural Affairs under Section 16 of the Environmental Better
regulation Act (Northern Ireland) 2016. In Wales these are authorised by regulations made by
Welsh Ministers.
The Fireline FGi/FXi/FP5, FGi/FXi/FPi 5W and FGi/FXi/FPi 8 stoves have been recommended as
suitable for use in smoke control areas when burning wood logs. This is conditional upon fitting
the supplied secondary air control limiters and following the wood burning instructions
precisely. Suitable Authorised fuels can also be used in the appliances in Smoke Control Areas
(see Authorised fuels for use in Smoke Control Areas here
https://smokecontrol.defra.gov.uk/fuels.php ).
Further information on the requirements of the Clean Air Act can be found here:
https://www.gov.uk/smoke-control-area-rules . Your local authority is responsible for
implementing the Clean Air Act 1993 including designation and supervision of smoke control
areas and you can contact them for details of Clean Air Act requirements.
10FGi.FPi.FXi Issue 12 10/17
6.3. Air Controls
Keep air controls and inlets/outlets clean and free from ash or debris at all times. Keep
ventilator air inlet grilles (if fitted) clean and clear at all times.
Do not leave air controls fully open unless monitoring the fire as over firing damage (typically
buckling of components) can result which is not covered by any warranty.
Air Control Operation
6.3.1. Primary air - under grate
The tab lever with a hole in it just below the main glass window controls the primary air supply
to the under grate area. The open position for the primary air slider should only be used for
smokeless fuel operations when it will control the burning rate and heat output. Take care not
to open it too far for too long as this can cause over-firing. Unless boosting a low fire bed or
your flue draught is very low it is not necessary to use primary air at all for wood burning – keep
it closed.
6.3.2. Secondary Air - Air Wash
All Charlton & Jenrick stoves are provided with a sophisticated “airwash” system to assist in
keeping the fire as visible as possible and reducing (not eliminating) cleaning intervals. This
secondary air supply to the stove is controlled through the slider above the door. The Clean Air
Act air restrictor bracket will deliberately prevent full closure of this control. Set the secondary
air wash control only about 4mm open for briquetted smokeless fuels, opening it further will
just reduce efficiency. It may be opened almost fully (depending upon flue draught) for wood
burning if a high burn rate/heat output required. The closed position of the air wash control
should only be used if absolutely necessary for very slow burning and when burning wood will
cause the glass to become blackened, the chimney to gradually become tarred and smoke to be
emitted from the stove. This is not recommended.
6.3.3.Wood burning:
Move the air wash slider fully to the right (open) for maximum air to start or revive a wood fire.
Returning the lever towards the centre position will reduce the air supply progressively to
reduce the burn rate. The nominal burn rate is usually achieved when the stove is fully warmed
up (2-3 loads of logs) and burning dry hardwood logs by having the lever very approximately 1215mm from the closed position. This is only a rough guide as flue and fuel conditions will vary
the required position. The maximum position will supply a boost of air to get new fuel burning
quickly in order to minimise smoke. Do not leave on maximum setting unless monitoring the fire
to ensure over firing damage does not occur. The fire will automatically be supplied with the
correct mix of tertiary air for complete combustion. NOTE: It is not normally necessary to open
the primary air at all once the stove is warmed up when burning wood unless the flue draught
or wood moisture are out of specification. Doing so may over fire the stove.
6.3.4. Smokeless coal fuel burning:
Move the air wash control slider fully to the right side and open the primary air slider below the
glass panel fully for starting or reviving a coal fire. Returning the slider towards the closed
position will reduce the air supply progressively as the fire warms up. Do not leave any control
at maximum setting unless monitoring the fire to ensure over firing damage does not occur
NOTE: It is not necessary to open the secondary air slider more than 3-4mm once the stove is
warmed up when burning smokeless coals. Opening any further will keep the glass slightly
cleaner but will reduce thermal efficiency.
11FGi.FPi.FXi Issue 12 10/17
6.3.5. Tertiary Air
This appliance is also fitted with a draught controlled tertiary air system that burns otherwise
uncombusted gasses thereby improving efficiency, increasing heat output and decreasing
unwanted emissions. The Tertiary air supply to the stove is controlled automatically by the
draught in the flue and firebox. At certain stages of burning you will notice “jets” of flame
emerging near the air holes to the rear of the firebox. This is not always visible depending upon
the fuels used and burn cycle stage so there is nothing untoward if it cannot be seen.
6.4. Multifuel Grate
Your stove is fitted with a multifuel grate. A build up of wood ash when burning wood will not
harm the grate and indeed wood is said to burn well on a bed of ash but excessive wood ash
build up is not recommended. Smokeless fuel ash must be regularly removed and NOT allowed
to build up under the grate.
The tab lever with a hole in it just below the main glass window controls the primary air supply
to the under grate area for burning briquetted smokeless fuels only. The primary air supply will
normally be around 50% open (100% open for 8kW version) for nominal output at average flue
draughts but will vary from one installation to another.
The primary air control must be closed when burning wood under normal circumstances.
Opening the primary air control too wide can over-fire the stove and permanently damage it if
left in operation. Any such over-firing damage is NOT covered by any warranty.
6.5. Ashpan
The ash pan assembly has seals around it that must be well maintained for correct burning of
wood with the primary air supply closed. If air leaks that may develop due to seal wear or
damage are not corrected then wood burning may become difficult to control. Check and
maintain the sealing of this area very carefully.
It is essential that you empty the stainless steel ash pan regularly when burning coal type fuels.
Use the flat end of tool to lift the ash pan out of the stove. DO NOT allow coal ash to build up
underneath the bed as this may cause damage to the grate.
6.6. Cleaning
Glass: Despite the advanced air wash system provided, the glass will still need cleaning from
time to time depending on the fuel quality and burning rates used. Never clean glass when the
stove is hot. Always use stove glass cleaner or ceramic hob cleaner, which is available from your
stove retailer or supermarket. As an alternative, use a wet cloth with some of the wood ash if
burning wood but be very careful to use very clean ash so as not to scratch the glass. DO NOT
use coal ash to clean the glass.
Outer body: The outer body simply needs to be dusted or wiped with a clean dry cloth from
time to time. DO NOT use wet cloths as it can spread plaster, cement, fire cement or fire board
dust and subsequently cause the paint to turn grey with heat where it has been wiped. DO NOT
use any kind of furniture polish or cleaning agent other than your stove suppliers recommended
paint.
Inner firebox: Brush the inside of the firebox clean from time to time to check the integrity of
the plates and liners etc. See Maintenance Guide section for instructions on how to remove
parts of the stove. It is not normally necessary to paint inside the firebox due to the high
temperatures that mean that the paint does not have much effect before being burnt off. Steel
and ceramic firebox liners are very resilient firebox materials and will give reliable service
without major cleaning or work on the firebox. The ceramic firebox linings may require
replacement occasionally depending upon fuels and the type of usage experienced. Firebox
12FGi.FPi.FXi Issue 12 10/17
linings are able to continue in service with cracks or repairs by fire cement, as long as the steel
underneath is not exposed to the fire. Firebox linings are not covered by warranty, as they are a
wearing consumable part.
Baffle: It is essential to check the top of the baffle for build up of soot and ash regularly when in
use and after a long period of disuse. From time to time remove the baffle if necessary to
ensure that the flue way entrance is completely clear. Baffle plates will require replacement
from time to time and are a wearing consumable part.
Air Supply: It is essential to check any air supply ventilator in the property is fully clear and open
if installed.
6.7. Fuels
The appliance is fitted with a versatile multifuel grate and has been tested and approved
burning dry, well-seasoned logs (<20% moisture) or briquetted Maxibrite smokeless fuel. These
are the recommended fuels. For other fuels please contact the manufacturer for advice.
The side firebricks supplied must be used for burning smokeless briquetted fuels on FPi5W and
FPi8 models. The side firebricks are NOT required for wood burning.
Note: Warning!- Petroleum coke fuels or household waste must not be burnt on this
appliance.
Should any difficulties arise over fuel quality or suitability, consult your local approved fuel
merchant.
6.8. Important Information for Wood Burning
With a full load of wood and burning near nominal output the stove will typically need to be
refuelled approximately every 45 min to 1.5 hours but this is entirely dependent on fuel quality.
One or two large logs will generally burn longer and cleaner than a number of smaller ones.
Wood can usually be stacked higher in the stove than solid mineral fuel but care must be taken
that logs do not touch the baffle or the glass panel. Do not stack logs above the level of the rear
firebox liner brick at the back of the stove.
Wood burns most efficiently with the primary air controls closed and the secondary (air wash) controls open. Carefully adjusting the secondary air controls and fuel load will then control the
burn rate of the stove. Typical air wash openings of 3-6mm are common for nominal outputs
depending on fuel quality and draught from the chimney which will differ in each installation.
Always make sure that flames are visible above the wood rapidly after re-fuelling for cleanest
burning. Burning without flames above the fuel will create unnecessary smoke and poor heat
output. After re-fuelling open the air wash control fully to the right side for 3 minutes or until
the logs are fully blackened to achieve full flames above the fuel. Move the door ajar for a
short time if necessary to establish the flames.
Wood burns well on a bed of ash and it is therefore only necessary to remove surplus ash from
the stove occasionally.
Burn only dry, well-seasoned wood, which should have been cut, split and stacked - under cover
from rain - for at least 12-24 months with free air movement around the sides of the stack to
enable it to dry out. A good burn-ready alternative is kiln dried wood logs. Burning wet or
unseasoned wood will create tar deposits in the stove and chimney and will not produce a
satisfactory heat output. Wood that is not properly dry (‘dry’ is considered to be less than 20%
internal moisture content) uses up energy from the burn process to evaporate the water
inside the wood thus creating very poor conditions for combustion. The main cause of burning
13FGi.FPi.FXi Issue 12 10/17
problems with wood stoves is due to excessively damp wood. Wood can appear perfectly dry on
the outside but still contain 40-50% water on the inside. A moisture meter can be purchased
from stove and equipment suppliers if you wish to check your wood source is correct. Split a log
and check the inside as well as the outside.
The ash pan assembly has seals around it that must be well maintained for correct burning of
wood with the primary air supply closed. If air leaks that may develop due to seal wear or
damage are not corrected then wood burning may become difficult to control. Check and
maintain the sealing of this area very carefully.
6.8.1.Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke
emission can occur. Refuelling must be carried out onto a sufficient quantity of glowing embers
and ash so that the new fuel charge will ignite in a reasonable period. If there are too few
embers in the fire bed, add suitable kindling and firelighter if necessary to prevent excessive
smoke.
6.8.2.Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can
cause excess smoke. Never load fuel above the back firebrick firebox liner or allow it to touch
the glass. All models max log diameter = approx. 150mm. Max length = 300mm for 5, 395mm
for 5 Wide and 540mm for 8 models. One log is acceptable ONLY if loading onto a hot, well
established fire bed.
6.8.3.Operation with door left open
Operation with the door open can cause excess smoke and spillage into the room. The
appliance must not be operated with the appliance door left open.
6.8.4. Primary Air left open
Operation with the primary air controls left open can create excess smoke and over-fire the
stove if left open when burning wood. The appliance must not be operated on wood with
primary air controls or door left open. Leaving the door ajar when hot can also cause over firing
and smoke emissions.
6.9. Information on Smokeless Fuel (Maxibrite) burning
The side firebricks supplied must be used for burning smokeless Maxibrite, briquetted fuels on
FPi5W and FPi8 models see diagram below. Briquetted smokeless coal type fuels require very
different burning conditions to log burning and the stove controls allow for this. Set the
secondary airwash control at about 4mm maximum open (wider will reduce efficiency) and set
the primary air control as required to adjust the burn rate. Once the initial charge of fuel is
glowing well with full primary air, re-fuel with a deep bed using these types of fuel but do not go
above the rear firebox lining board or put excessive fuel on top of the side firebricks on the
FPi5W and FPi8. Maxibrite and other smokeless briquetted fuels can burn with very little
primary air and stay in for many hours to be revived after an overnight burn for example. NEVER
use household coal, petroleum (pet) coke or any grade of smoky coals.
14FGi.FPi.FXi Issue 12 10/17
6.10. Lighting the stove
We recommend that you have two or three small fires
before you operate your stove to its maximum heat
output. This is to allow the paint to cure in steadily and
to give a long service life of the paint finish. During this
curing in process you may notice an unpleasant smell
whilst the finishes finally cure. It is non-toxic, but for
your comfort we would suggest that during this period
you leave all doors and windows open.
First, open the secondary air wash slider control fully. Load the
firebox with some fully dry small or split logs in a crossed
pattern. Make sure the grate is well covered and no big gaps
are present.
Next add plenty of starting fuel, i.e. paper, dry kindling sticks
and a firelighter ON TOP of the 4 logs. A crib lattice pattern
tends to work well. If using Maxibrite, place a layer of
Maxibrite into the firebox on the base as well and omit the
large logs but use plenty of kindling with briquettes all around
so that the charcoal from the wood ignites the Maxibrite well.
Light the firelighter(s), leaving the air controls fully open the
door slightly ajar for 5-10 minutes to enhance initial starting
and reduce smoke emission – DO NOT leave the stove
unattended if you find it necessary to leave the door ajar.
The kindling will burn and set light to the logs by radiation and
breaking down to charcoal gradually and with fewer emissions
than the traditional logs on top methods.
Allow the fuel to reach a steady burn and usually the initial fuel can be left to burn down to
nearly charcoal without much further attention. Next build the fire up carefully by adding a
couple of small split logs or a relatively small
amount of Maxibrite briquettes at a time. Do
not overload the fire bed with more than two
or three small logs at a time.
Once you have a good fire bed established
across the grate, further fuel can be added step
by step as required. A good indication of a well
established smokeless fuel fire is the
widespread coverage of grey ash on the black
fuel pieces. Don’t be tempted to overload the
fire bed with fuel all at once or close down the
air controls too much until the fire is really well established for some time. Once the ignition
period is well under way, gradually reduce the air controls then fully close the primary air if
burning wood and use the controls to establish the burning intensity you require.
15FGi.FPi.FXi Issue 12 10/17
6.11. Re-fuelling
When burning Maxibrite the fire will begin to die down with a significant amount of white ash
showing amongst the fuel. Gently run a poker through the fire bed to remove most of the ash
into the ashpan. Empty the ashpan if it is nearly full and then re-fuel with a good load of
briquettes. The fuel load should initially be level with the top of the fuel retainer and not above
the rear firebox liner. Whilst approval test cycles are 1 or 2 hours, a stove burning Maxibrite
may be kept in overnight easily under normal conditions.
When burning wood, the fire will die down as the fuel is consumed. When the flames disappear
and the remainder is breaking down into glowing embers it is an appropriate time to consider
re-fuelling. Generally unless the firebox and firebed has cooled down and it is being revived up
to working temperature then it’snot appropriate to re-fuel when the logs are still flaming
fiercely. NOTE: If the flames disappear and there are still lumps of solid wood left this indicates
excessive internal moisture in the wood, too low a firebox temperature (running too cool), too
small a fuel load or insufficient air supply/flue draught.
NOTE: To eliminate unwanted smoke emission, after loading new logs on to the fire, open the
air wash control up fully for 3 - 5 minutes or until the logs are well blackened all over to boost
the fire and get flames issuing from the top of the fuel as soon as possible. Move the door ajar
for a time if necessary to establish flames. When flames are well established, reduce the air
wash to the running setting required. Burning without flames above the fuel will create unnecessary smoke. Do not load fuel above the rear firebrick at the back of the firebox.
Loading 1 or 2 medium-large sized logs weighing 1-2kg DRY will produce a good output with
reasonable burn time. Small logs will burn up quicker producing a high output and more
emissions for a short time, and a large log will take longer to burn and produce less output and
less emissions over a given time. These appliances are approved for intermittent operation on
wood (typically 0.75 to 1.5 hour burn cycles) although longer burn times can be achieved by
fully loading the firebox, getting the fuel burning well and then shutting the air controls right
down (see below). This will produce a long but smoky/tarry burn (not recommended). The fire
will then need reviving by first opening the air controls and then using small pieces of wood and
plenty of air to get flames issuing from the wood again. The glass will get dirty if closing the air
wash control past the point where flames above the logs disappear – this is quite normal. Never
load fuel above the rear firebrick or allow it to spill onto the glass.
6.12. Shutting Down
The stove will normally shut down by itself as the fuel is consumed so there is no need to close
the air control towards the end of the burn. In order to shut down the stove for other reasons,
close the primary air controls (if open), then close the secondary air control. If the controls are
left in this position, the fire will eventually go out but it will also cause the glass to blacken/grey
out as the fire dies down. If you want to revive the fire it is recommended that the secondary air
controls are opened fully first followed by the primary air control until revived.
Warning! - The stove will remain very hot for a considerable time after the fire has died down
or been extinguished.
6.13. Shut down for prolonged periods
If the stove is to be left unused for a prolonged period of time then it should be given a
thorough clean to remove ash and unburned fuel residues. To enable a good flow of air through
the appliance to reduce condensation and subsequent corrosion damage, leave the air controls
fully open. It is important that the flue connection, any appliance baffles or throat plates and
the chimney are swept prior to lighting up after a prolonged shutdown period.
16FGi.FPi.FXi Issue 12 10/17
6.14. User Maintenance
See also the Cleaning section above and Maintenance Guide Section below for further
information.
Inspect the inside of the firebox and above the baffle plate every week during use.
Where the chimney is believed to have previously served an open fire installation, it is possible
that the higher flue gas temperature from the stove may loosen deposits that were previously
firmly adhered, with the consequent risk of flue blockage. It is therefore recommended that the
chimney be swept a second time within a month of regular use after installation. See chimney
cleaning section.
Warnings and Important Information. Inspect the inside of the stove and the flue ways and
ensure they are 100% clear after a period of disuse (e.g. summer).
Only use manufacturers recommended replacement parts on the appliance.
Check all rope seals and glass gasket seals for completeness, wear and that there are no gaps
between the ends etc. Any gaps must be eliminated and ropes must be re-adhered to their
grooves with suitable rope seal cement where required. Worn or missing rope or glass gasket
seals will affect appliance operation, control and emissions output and can lead to
overheating damage.
Check all air intakes and outlets within the stove for cleanliness and remove any ash or debris
build up by suitable means.
Check outside air ventilators and stove air inlets are clean and unobstructed.
Only use manufacturers recommended replacement parts on the appliance.

7.0 Maintenance Guide
7.1 Removing Door. Open the door to approximately 30 degrees and lift away to
disengage the hinge pins. Note that it is not necessary to remove the door to
clean or remove items from inside the firebox.
7.2Removing Fuel retainer bars: The fuel retainer bars also retain the side firebrick
liners. Lift bar assembly up until it can be rotated and removed from the firebox.
7.3Removing Firebox Liners: Gently move either side firebrick forwards and slightly
towards the centre of the grate to release them from the rear liner. There is a
mitre joint at the rear which retains both when in position and when disengaged
frees all components. NOTE: Make sure the rear firebrick does not fall forwards
and break as the side liners are released!
7.4 Removing Baffle Plate: Slide the baffle plate slightly towards the front of the
stove and lower it off the rear support then the front pins. Rotate the baffle
slightly and remove through the front of the stove. The upper baffle plate can
now be removed by unscrewing the stainless steel securing screws and lifting
away. The flue can now be swept through the stove.
7.5Removing the grate: Remove the fuel retainer, firebrick liners and baffle as
above. Lift out the grate castings from the stove firebox.
7.6Changing the ceramic glass panel: From time to time the ceramic glass panel or
its gasket seals will need to be changed. Note that ONLY ceramic stove glass in
the same thickness can safely be used. This is easiest to accomplish with the door
removed from the stove and placed face down on a cushioned surface such as
cardboard or a folded dust sheet. Firstly clean the inside surfaces of the door and
remove the M5 stainless screws that secure the stainless steel glass clips to the
door. The glass panel can then be carefully removed. Take the opportunity to
clean the glass panel thoroughly if it is to be re-used. Remove all traces of seal
from the door casting and clean the surfaces ready for new seals. There is a small
woven seal beneath the glass panel instead of gasket paper strips. Fit new seals
into place forming a continuous glass seal all around the panel seating area. Line
up carefully leaving NO GAPS. Replace the glass panel into position followed by
the clips and screws. A strip of gasket material between each metal clip and the
glass can extend glass panel life by spreading compression forces evenly. Tighten
the four screws in turn to gradually compress the new gaskets and seal the new
panel into position.
7.7Adjusting door: Adjustment can be made to the hinges. Hinges have a limited
amount of adjustment which is achieved by slackening the mounting screws and
re-positioning before re-tightening the screws. To obtain greater seal clamping
force adjustment the hinge blocks can be shimmed by using metal packing under
them to create the correct spacing for the seals in use.
7.8Replacing door seals: Rope seals are fixed in place with stove seal adhesive. This
is sometimes ceramic in formulation or high temperature silicone such as Heat
Mate which is more flexible. NEVER use ordinary glazing or sanitary silicone
adhesives as they cannot withstand the temperature. Simply pull away old seals,
scrape off excess old adhesives. Apply new adhesive continuously onto the
mounting face and apply the new rope evenly all around. NOTE: Ensure NO gaps
at the meeting ends of any continuous loops or butt joints and that the rope sits
properly into corners. Close the stove door and leave to dry for several hours
before firing. Seals can be tested by trapping a strip of paper and closing the door
18FGi.FPi.FXi Issue 12 10/17
on it. If the paper is trapped then the seal is working. If the paper pulls out them
something is wrong and further examination is needed to find the cause.
7.9Re-painting: All painted solid fuel stoves will require some re-painting from time
to time due to heat cycling, wear and tear and corrosion caused by moisture,
condensation or products of combustion and ash. The stove can simply be repainted by using stove spray paint or high temperature coatings after rubbing
down with wire wool or similar abrasive to remove all loose debris from the
surfaces.
7.10Re-assembly: This is the reverse of the dismantling procedure – again taking
particular care not to drop the firebox liners onto the cast iron grate as reassembly takes place.

9.0 Frequently Asked Questions
1 Do stoves require a chimney or a liner? All of our stoves require a suitable chimney or
professionally installed flue system. A liner may or may not be required depending on flue
conditions and only your installer can confirm. Our stoves do not mandatorily require a liner.
2 How do I clean the chimney? You will require a chimney sweep to clean the chimney. It is
essential to provide a dedicated chimney cleaning access door when installing the flue of the
stove in some situations. In many situations the chimney can be swept through the firebox.
3 Who should install my stove? Charlton & Jenrick want you to enjoy the maximum
performance from your appliance. To ensure this, it is essential that they are installed correctly.
We strongly recommend that your stove is installed by a suitably qualified installer e.g HETAS.
4 How do I regulate the heat output? Each stove has various air controls, which will allow you
to easily regulate the heat output. Output can also be varied by log size and quantity fired.
5 What warranty do I get? Charlton & Jenrick will replace, free of charge, any part that fails
(under normal operating conditions) within 12 months of purchase. Consumables such as glass,
firebox lining boards or stove rope and adhesives are not guaranteed. We do not accept
consequential or incidental liability claims from any product failure. A call out charge will apply
if our engineer attends any stove problem that is not related to product failure.
6 Where can I get spare parts? Your local stove retailer will be pleased to supply spare parts
and to provide any other information you require. Alternatively contact Charlton & Jenrick.
7 Can the doors be left open while burning? For safety and heat efficiency the doors should
remain closed. These stoves are not designed or approved for doors open operation.
8 Why is the stove smoking when lit? A flue with lack of draught problems is almost certainly
the cause of a smoking stove. Also check adequate ventilation is present – if opening a window
or door stops the smoking then lack of ventilation is the probable main cause. A qualified fitter
should complete both a smoke pressure and flow test prior to fitting the stove to ascertain the
integrity of the flue.
9 Why should I “Run in” my stove? To begin, light a series of small fires over a period of a few
days to allow the paint finish to cure. The stove is finished with a highly heat resistant paint. The
finish can be renovated with stove paint available from your stove retailer. If the stove is not
“run in” correctly, this may cause the paint to discolour and flake.
10 What is Over Firing? Over firing is overheating your stove by having the fire burning too
fiercely. Your stove should never be used in a manner to cause over firing. Over firing can be
caused by over loading the stove with fuel or leaving air controls fully open or operating the
stove with leaking or defective door rope seals. If any part of stove glows red hot then your
stove is over firing and your air control should be adjusted to reduce airflow to stove
immediately. Over firing can cause permanent damage to the appliance, which is not covered
by warranty.
