REGULATIONS AND INSTALLATION INSTRUCTIONS
FOR WOODWARM STOVES
All local regulations, including those referring to national and European Standards (BS 6461, Installation of
chimneys and flues for domestic appliances burning solid fuel (including wood and peat) & BS 8303, Code of
practice for installation of domestic heating and cooking appliances burning solid mineral fuel) need to be
complied with when installing this appliance.
Health and Safety at Work
It is the responsibility of the installer to comply with current Health and Safety Regulations, and particular attention
should be given to the following: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.
Handling
This stove is heavy and adequate facilities must be available for all handling operations and its final manoeuvre into
position. In order to lighten the stove, the main door may be removed. The baffle and grate bars can also be removed.
Glass
Care should be taken when handling the door that the glass is not knocked. The door is double glazed.
Fire Cement
Some types of Fire Cement are caustic and should not be allowed to come into contact with the skin. In cases of contact, wash off with plenty of water.
Electrical
If any electrical components are used in the installation they should be installed in accordance with the manufacturers
installation instructions and all wiring must comply with the current I.E.E regulations and the by-laws of the local water
authority.
Air Supply
Building Regulations dictate that an air vent of some type (usually an air brick) must be fitted into an exterior wall to allow sufficient flow of air into the fire. Air Inlet grills must be so positioned that they are not liable to blockage.
This stove should not be fitted in a room where an extractor fan is in use, as this could result in flue reversal and the
emission of flue gases into the room.
A carbon monoxide alarm must be fitted to BS EN 50291:2001
HEARTH
The stove must stand on a fireproof hearth which must be at least 127mm thick and constructed of a noncombustible material. The positioning of the stove and the size of the hearth is governed by Building
Regulations for Class 1 Appliances. These regulations state that the hearth must extend at least 225mm in front and
152mm to the side of the stove. This can be covered with decorative tiles so long as these are also
non-combustible.
SUPER IMPOSED HEARTH
In certain circumstances Building Regulations allow for a super imposed hearth. This must be a minimum 12mm noncombustible material e.g. slate, glass, steel. This stove comes with 72mm minimum leg detail which does not exceed 100°c and therefore is suitable for a Super imposed hearth. With the addition of Woodwarm accessories such as
legs, plinth, pedestal, the hearth temperature is further reduced.
4
STOVE SITE AND MINIMUM CLEARANCES
There must be no combustible material (i.e. plaster board, wooden wall panels, skirting boards, beams etc) within a
specified distance to the rear and sides of the stove, these can be found on table 1 page 3.
The clearance between the stove and any non-combustible surface is recommended as not less than 152mm the side
or rear and 300mm from above.
CHIMNEY AND FLUE
The chimney should be thoroughly swept and examined for soundness. If the chimney is not lined, then we
recommend strongly that before use it is fully lined with a Class 1 Liner and insulated (we recommend no more
than 600mm single skin flue from the appliance). It is not advisable to only partially line a chimney as this will
only create further problems where the lining finishes. If there are even the smallest air breaks in the mortar, the
chimney is not suitable for a wood stove. When hot flue gases rise up the chimney, it will pull cold air through any small
break. This cools the flue gases at that level causing wood tar to precipitate at that point on the chimney wall. Soon
this will accumulate across the chimney and therefore constrict it and stop the fire burning properly. Eventually this will
not only lead to a chimney fire, but will further rot the chimney structure. If the chimney is not lined and was previously
used for an open fire then there is a possibility that the higher temperatures produced by this closed appliance will
loosen deposits. It will be necessary to have the flue swept and inspected by a registered sweep one month after the
initial installation.
In the absence of a chimney one of the following must be used either internally or externally:- a prefabricated block
chimney, a conventionally constructed chimney with a Class 1 liner, or a twin walled insulated flue to BS 4543. The
internal diameter must not be less than that of your particular appliance. Flues must be fitted in accordance with
the manufacturers' instructions and according to local Building Regulations. If there is any doubt over the flue connection or the installation, consult your nearest professional installer, or the Building Inspector at your local council.
Whichever chimney option you choose to use DO NOT FORGET TO POSITION A CLEANING ACCESS
(if applicable) in your flue and chimney that is easily accessible for sweeping. Note: Clay liners can create a cool
upper internal temperature which can lead to condensation problems, especially if the liners are not back insulated. If a
clay liner is already in place we recommend lining with class 1 liner.
For efficient stove working it is important to make sure that there is an adequate draw on the chimney. The chimney
height should not be less than 4.5 metres measured vertically from the outlet of the stove to the top of the chimney. With
a minimum flue draft reading of 0.05mbar (0.02”wg) when warm, increasing to 0.15mbar (0.06”wg) when hot. These
readings should be taken using secondary air and all fire doors closed. The minimum flue size for these stoves varies
according to the model, refer to the specification sheet (table 1 page 3) for the minimum flue diameter. If possible line
the chimney with a flue liner that is at least 25mm (1") larger than that of your particular stove. At no point in the flue
should it be below the minimum flue diameter.
When the stove is to be connected to an existing fireplace, this will need sealing to the flue by a register plate, which can
be mounted horizontally or vertically.
This appliance is unsuitable for use in a shared flue system. If elsewhere in the house another fireplace feeds into
the same chimney this must be sealed, otherwise flue gases or air may either be drawn into or escape from, the other
chimney or fireplace. This would contravene Building Regulations as it is potentially very dangerous.
CHIMNEYS, FLUES, COMBUSTION, AIR SUPPLY AND POSITIONING OF THE STOVE
In addition to these installation instructions, Building Regulations and Local Authority By-Laws regarding flues and
positioning of the appliance. (Building Regulations Document J must be observed).
AIR VENTILATION AND FREE AIR:
The stove requires 550 mm2 of FREE AIR space per KW input in excess of 5kw. Therefore, a 9kw input appliance
requires 2200mm of free air.
9KW - 5KW = 4KW
4KW x 550mm2 = 2200mm2
There must not be a extractor fan fitted in the same room as the stove as this can cause the stove to emit fumes
into the room.

INSTALLING THE STOVE
Warning: — Use packing to avoid damage to underside Air Controls when moving on trucks!
Ensure that the Air Controls move freely before final positioning and installing
Always leave Air Controls open to shake out any loose material when moving stove
( If jammed, spin off the 6no domed nuts and clear obstruction )
Remember to leave sufficient clearance in front of the stove for the fire door to open fully. Place stove on
chosen level hearth and remove any packaging materials. The shrink polythene can be used as a cover for the
stove whilst installation is in progress as fire cement will mark the stove paint surface if left.
There is normally a piece of cardboard , for protection, behind the door glass. All other pieces of board in the
stove are the fire boards. Turn the handle and open the fire door then carefully remove it by lifting up and off its
hinge pins (retaining these) and place it safely out of the way. From the front of the stove you can now
remove the operating tool, baffle, fire boards, the grate bars and ashpan if necessary.
The ashpan can be used for holding the grate bars if you need to remove them, which can be done easily by
rotating them fully open then lifting each one out of the grate link bar, outwards and upwards.
The flue spigot supplied with the Woodwarm is 127mm and is interchangeable with the blanking plate. There is a
rope seal on both the blanking plate and the flue spigot to ensure an gas tight seal. Locate the blanking plate and
the flue spigot in their chosen apertures and then tighten the screws and nuts to ensure a good seal.
Fire cement and/or a length of fireproof rope should be used to seal the joint of the flue pipe into the flue spigot.
This should also be applied to the joint between two flue pipes and where the flue pipe joins your chosen register
plate.
Stainless Steel self-tapping screws or nuts and set screws should be used to reinforce the above joints where applicable.
Carefully remove any excess fire cement immediately to ensure no marking of the stove finish.
Replace the door by aligning it over the hinges and working the door downwards whilst at the same time, gently
swinging it. Warning: Use a second person to take the weight, as the door is heavy.
INTERNAL FIRE BOARDS
These stoves are for both wood and solid fuel and the interior of the fire chamber of all of them is lined with
30mm Mica based fire resistant board . There are three pieces, one at the rear under the baffle and flue outlet
and one on either side of the stove. Fig3 These fire boards are ready cut to size and shape and may be packed
loose to prevent damage. They are very fragile so handle with care, especially when loading with fuel. They have
a relatively short life, especially when burning coal, so do inspect them regularly and replace if they begin to deteriorate by showing signs of breaking up or wearing thin. The fire board is important for efficient combustion and is
not covered by any warranty as it is considered a consumable product.
The replacement sizes are provided under Stove Fire boards on table 1 page 3.
BAFFLE
The smoke baffle sits on the rear board as shown in Fig.4 and 5. Ensure baffle seats squarely on rear board
LOGGUARD AND SOLID FUEL INFILL’S (Gem / Blaze only)
Install these as per Fig. 6a to Fig. 7c
COMMISSIONING
On completion of the installation and after allowing a suitable period of time for any fire cement or mortar joints to
dry out, the stove should be cleaned using a soft dry cloth. Check joints and seals. The stove can then be lit and
checked to ensure that smoke is taken from the appliance up the chimney and emitted safely.
The customer should be advised on the use of the appliance.
On completion of the installation and commissioning please leave these operating instructions with the
customer.
HETAS LTD APPROVAL
These appliances have been approved by HETAS Ltd and Defra as an intermittent operating appliance for burning
the fuels listed on page 13.

FIRE DOOR - ALL MODELS
Check when refitting the fire door that the rope seal on the inner face of the door is making an even contact with the
stove body when the door is closed. Your Fireview stove is supplied with a heat resistant glove to operate the door handle e.t.c., when hot. Turn handle to clockwise to open and turn anti-clockwise to lock.
The door catches can be adjusted but ensure that the lock nuts are tight and the catches are pulling evenly and positioned pointing straight down( Fig. 8c) .
This appliance must only be used with the door closed

GLASS PANELS
There are two panels of glass in each door. They are made of a heat resistant ceramic product which will not
break with the heat of the fire. However, it is important to maintain the movement of the glass within the door as,
if the glass is restricted, it is likely to crack with the expansion or contraction of the cast door. To achieve this it
has heat resistant fibre glass ladder rope around the edges and this should be replaced if it is showing signs of
deterioration.
CLEANING
The glass can be cleaned when hot without damage to the panel although care must be taken not to burn your
fingers etc., also care must be taken with aerosol cleaners and cleaning cloths. We recommend the proprietary
stove glass cleaners. When solid fuel is being burnt any sooty deposits on the glass can be cleaned simply by
wiping with a dry cloth.
If the stove glass becomes dirty this is either due to the closing of the airwash before the fuel is up to temperature
and/or wood fuel is too wet. If a routine is established of hard burning on secondary air only for 20 minutes at
each end of the day this will assist in keeping your glass clean.
REPLACEMENT
Carefully lift the fire door from its hinge pins and lay it down - preferably on a soft substance - being aware of the
door fastening catch. The outer glass panel (furthest from the fire) is mounted on fibre glass ladder rope which
should surround all the edges (Fig. 9). Caution is required when replacing this glass panel as the ladder rope
has a tendency to slip out of position as the glass is fitted. The second or inner panel then fits directly on top of
the outer followed by the top and bottom steel glass retainer and the whole held together by the 4 x (M4 x 10mm)
machine screws. It is recommended to apply some heat resistant copper grease or graphite grease to the screws
and DO NOT OVER TIGHTEN THEM as the glass panels will crack.
The stove requires both of these glass panels in place to achieve a clean burn state as they act in a similar way
to double glazing in a domestic window.

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 for use in
an “exempt” appliance (“exempted from the controls which generally apply in the smoke control area).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power
rests with Ministers in the devolved administrations for those countries. Separate legislation, the Clean Air
(Northern Ireland) Order1981, applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have been authorised in Regulations and that appliances used to burn
solid fuel in those areas (other than “authorised” fuels) have been exempted by an Order made and signed by
the Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act can be found here:
http://smokecontrol.defra.gov.uk/
Your local 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.
RECOMMENDED FUELS
The FireWren, Gem and Blaze appliances when modified to fix the secondary air rotating plate 5mm
open in it’s fully closed position, have been recommended as suitable for use in smoke controlled
areas when burning Smokeless fuel or dry wood.
Dry wood means that it has not more than 20% moisture content. If these operating instructions are followed correctly no significant smoke will be produced. Burning wet ( >20% moisture content ) wood and operating the stove in an irresponsible manner may produce smoke which is illegal in smoke controlled areas.
Wood to be used as a fuel should be logged, chopped and stored in a sheltered but airy site for an absolute
minimum of 12 months and preferably 24 months. Wood naturally dries at the rate of 1" per year so a 12"
round will take 6 years to dry to the centre. Do not be tempted to stack wet wood on or around the stove
believing this will dry the sap out of the wood. A 12" log takes approx 8 weeks in a kiln to dry to 18% moisture
and doing so carries a high Fire risk Freshly cut green wood - i.e. wood that still has sap in it - is dangerous
to burn. It will cause a chimney to choke with wood tar in a few weeks with a grave risk of a chimney fire resulting. In any case, burning sap wet wood is pointless. It produces far less heat, maybe as little as 10% of that
of dry wood. Wood burns best on a bed of ash so do be careful to retain some when de-ashing.
Do not burn treated wood and assume that any bought in wood is wet unless its history is known.
Tar is caused by burning wet wood. It is brown/black in colour and may be liquid. It has an offensive smell. On
the sides of the stove, flue and chimney it resembles a black sticky 'chewing gum' and can eventually block the
flue ways. When it ignites, it can cause a chimney fire and be highly dangerous.
Please note that HETAS Ltd Appliance Approval only covers the use of the above fuels on these appliances.
HETAS Ltd Approval does not cover the use of other fuels either alone or mixed with the recommended fuels
listed above, nor does it cover instructions for the use of other fuels.
Never spray aerosols near the stove when it is alight as an explosion could occur if flammable vapours or gases
come into contact with naked flames.
13
OPERATING INSTRUCTIONS
Before lighting check with the installer that the work and checks described in the previous pages of this booklet have
been carried out correctly and that the chimney is sound, has been swept and is free from any obstructions.
HOW CLEAN BURN WORKS
These stoves use Secondary Air, which passes through long preheated air inlet ducts and exits as an 'Air Curtain’,
down over the glass, keeping most of the normal tar deposits from condensing on the glass. The movement of this air
also promotes a 'Rolling Action' that mixes and re-burns harmful deposits to give a
'Clean Burn' .
LIGHTING
Open both Primary and Secondary air controls (Fig.17), by turning each fully clockwise.
The stove can be lit using paper, dry kindling, and/or fire lighters. Place the paper and kindling or fire-lighters on the
grate and cover with wood or a 50mm layer of solid fuel (Never overload the firebox). Light the fire and close the
stove door.
Wait until the fuel is well alight then load fuel and adjust the air controls to suit as described on the opposite page.
PAINT CURE DURING INITIAL LIGHTING
Note The paint used for finishing the stove will emit fumes as it "cures" during initial firings. Also when at temperature
prior to curing, the paint will be very soft and can mark easily. Ensure good ventilation by opening doors and windows and avoid marking the paint surface.
It is best to avoid opening the stove door during

Secondary Air Control
(Airwash Air)
RUNNING - SAFELY, CLEANLY, EFFICIENTLY
WOOD FUEL (less than 20% moisture)
When the fire is well established, (the stove body has reached a temperature of 250-280oC (450-500o F) on a
Stove thermometer), close the primary air control. The stove may now be run on the secondary air control . ( Fig.17)
SOLID FUEL (must be smokless fuel in a smoke control zone)
When the fire is well established (the stove body has reached a temperature of 250-280oC (450-500o F) on a Stove
thermometer), use minimal secondary air to aid glass cleaning and run with primary air to burn the fuel.
Warning : Excessive air will cause over firing and damage of the stove. Check for the effects of your air settings
before leaving the appliance unattended. ( this won’t be apparent until 5-10 minutes after altering)
When refuelling the stove, first open the secondary air control to increase the draw of the fire and allow the chimney
to warm up, this will draw any smoke/fumes up the chimney when you open the main door. To maintain the hot air
flow from the front of the stove to the rear, drag any un-burnt fuel to the front and add new fuel to the rear.
For recommended refuelling intervals see table 1.
EXTENDED BURNING PERIODS
When burning wood, if longer burning times are required use dry large logs of a hard wood rather than small ones,
remembering to keep a bed of ash above the grate bars.
Some fuels need more air than others to tick over, some experimentation will be necessary to find the right
setting.
THINGS TO AVOID - THE DONT’S

Loading the stove up and immediately closing any air controls before a good burn is established, as
this causes excessive smoking, inefficient burning of fuel and can result in the alarming detonation of
gases.

Do not refuel onto a low or cool bed of embers as excessive smoke emission can occur. Refuelling
must be carried out onto a sufficient quantity of glowing embers and ash that a new fuel charge will
ignite in a reasonable period. Do not exceed the maximum amount of fuel specified. If there are too few
embers in the fire bed, add suitable kindling to prevent excessive smoking.

Do not allow ash residue to build up below or above the grate to such an extent that air cannot enter
the fire through the inlet holes beside the ash pan and travel up through the grate bars (Primary Air)
Too much ash underneath the grate bars, can cause them to jam or overheat and distort.

Do not allow ash residue or fuel to build up against the logguard to such an extent that air cannot enter
the fire through the logguard from the Airwash down over the glass.

Emptying hot ash and embers into the Ashpan can cause it to distort . Ensure that hot ash and embers
are not emptied into plastic bin liners or other flammable containers. Allow these to cool prior to disposal.

Leaving the room before ensuring that the new refuel is well alight.

Do not operate the stove with the door open as this can cause excessive smoking.

Do not leave the operating tool attached to the stove when the stove is in use as it will get very hot.
When the stove is in use the body will be too hot to touch by hand. Children and infirm people should
be prevented from touching it accidently, by using a suitable fire guard. This should be manufactured
to BS 6539.

Combustible materials should never be left on or near the stove when it is alight. Linen, wool, wood
and many other materials can spontaneously ignite if they become too hot. They do not have to come
in direct contact with flames.
Operation with the air controls or dampers open, can cause excess smoke. The appliance must not be
operated with the air controls, dampers or door left open except as directed in the instructions.

15
OPERATION OF GRATE
Your stove is fitted with a multi-fuel grate (Fig. 11a and 11b) which will enable you to burn wood or solid fuel equally
effectively. It consists of a grate lever operating handle (shown in yellow), grate bars (shown in blue) and the grate link
bar (shown in pink). Once fuel is loaded on the grate the grate will remain where it has been
positioned). The grate is left with the bars closed for wood and slightly open for solid fuel,
GRATE INFILLS
When burning solid fuel, the Grate Infill's can be used to enhance operation by allowing more combustion air
to reach fuel at the sides and also to direct waste toward the grate itself.
DE-ASHING
Using the tool provided (shown in yellow) the grate is gently and NOT FORCEFULLY rotated clockwise to open and
rocked open and shut in order to de-ash. Once de-ashing is completed return the grate to the closed position .
Using a small movement will dislodge all but the largest clinkers through to the ashpan.
Too much riddling/poking can result in unburnt fuel being emptied into the ash pan and should be avoided. Any
clinkers should be regularly removed from the fire bed. The ashpan should be emptied regularly before it becomes too
full. Use the operating tool to handle the ashpan, taking care not to spill the ashes as there may well be hot embers
still glowing in the pan.
If the grate bars will not rotate easily DO NOT FORCE them but investigate the possible cause, i.e. clinker or nails
blocking movement or too much ash in ashpan and in the bottom of stove, and remedy as soon as
possible.
“Tippy” ash caddies are available from your local stockist greatly assist in the removal of ashes from the house.
Fig. 11a
Closed
Open
Fig. 11b
To ensure that the stove will not ‘overfire’ whilst the door is open, we would strongly recommend that deashing is only undertaken when either the fuel load is almost exhausted, the stove is out or in a very low
state.
16
DAILY ROUTINE , MAINTENANCE AND SERVICING
Daily - run the stove hot for a time using the procedure as explained on pages 14 and 15, along with a surface
mounted thermometer to ensure optimum temperature is reached. This will assist in cleaning any marginal deposits
of tar from the door glass, stove, flue and chimney internally. Check on the amount of ash in the ashpan and empty
if necessary.
Weekly - check seals, be they rope or fire cement, for air tightness. LUBRICATE the fire door catch if needed with
a high temperature or graphite based lubricant.
Ensure that the ash pit is clear of ash all the way to the rear, by removing the ashpan (Fig. 7c ) and checking. Also
clear any clinker or nails from the grate bars and grate bars, link bars and supports.
Twice yearly - check the condition of the fire boards and seals and replace if deteriorated. Remove and clean
over the baffle and clear flue ways, more often if burning solid fuel. A visit from the chimney sweep will remove the
small amount of ash dust which forms in the chimney if the above instructions are adhered to.
The names and addresses of your local Approved Chimney Sweeps can be obtained from either of the following:Guild of Master Sweeps or The National Association of Chimney Sweeps (see page 21 for contact details).
If the stove is to be left unlit for any period of time ensure the air vents are left open and the controls and
door catches are well lubricated with a high temperature/graphite based lubricant or other rust preventative.
Maintain the paint surface solely with a soft dry cloth and nothing more. The paint used is a durable heat proof
paint. It is, as a consequence, porous and is not waterproof. Before re-lighting the stove after a long period out of
use, check that all flue ways are clear of obstructions.

CHIMNEY FIRES
If the chimney is thoroughly and regularly swept, chimney fires should not occur. However, if a chimney fire does
occur turn the air control setting to the minimum, and tightly close the doors of the stove. This should cause the
chimney fire to go out in which case the control should be kept at the minimum setting until the fire in the stove
has gone out. The chimney and flue ways should then be cleaned. If the chimney fire does not go out when the
above action is taken then the fire brigade should be called immediately.
After a chimney fire the chimney should be carefully examined for any damage. Expert advice should be sought if
necessary.
FAULT FINDING
A) Stove smokes on lighting or when fire door is opened
Flue ways blocked - sweep chimney and flue.
Baffle incorrectly fitted.
Adverse wind conditions, or down draught - check height and diameter of chimney.
Flue not connected (or not sealed) to appliance or chimney .
B) Stove burns fuel too fast
Air controls open.
If the above are closed then excess air may be entering from elsewhere.
Check if door glass and ash pit door rope seals are damaged or not seating.
Check all flue connections are airtight. Check if flue blanking plate is airtight.
Go through installation procedures and cautionary notes.
Chimney draw too fast - fit flue stabiliser.
C) Door glass sooting up
Allow stove to reach body temperature before closing air wash.
Primary air inlet open, whilst Secondary air control is shut.
Use bottom air as choke only - i.e. minimal use.
Fuel load too close to the door.
FUME EMISSION
WARNING NOTE: WHEN PROPERLY INSTALLED AND OPERATED THIS APPLIANCE WILL NOT EMIT
FUMES OR SMOKE TO THE ROOM. OCCASIONAL FUMES FROM DE-ASHING AND RE-FUELLING MAY
OCCUR. PERSISTENT FUME OR SMOKE EMISSION TO THE ROOM MUST NOT BE TOLERATED.
IF EMISSION DOES PERSIST THEN THE FOLLOWING IMMEDIATE ACTION MUST BE TAKEN.
A
OPEN ALL DOORS AND WINDOWS TO VENTILATE THE ROOM
B
LET THE FUEL OUT AND SAFELY DISPOSE OF FUEL FROM THE APPLIANCE
C
CHECK FOR FLUE OR CHIMNEY BLOCKAGE AND CLEAN IF NECESSARY
D
DO NOT ATTEMPT TO RELIGHT THE FIRE UNTIL THE CAUSE OF THE FUMES HAS BEEN
IDENTIFIED, IF NECESSARY SEEK PROFESSIONAL ADVICE

IMPORTANT—READ THIS
MAXIMUM OPERATING TEMPERATURE
The stove body is designed to run up to a maximum temperature not exceeding 650F or 350C, beyond
which damage can occur. We recommend the use of a stove thermometer available from your dealer.
There are 3 possible causes for stoves over-heating :1.
Air controls, in particular the Primary ( under grate air), left too far open for too long. You will hear
the stove drawing too hard and the fuel bed will become White hot as will the surrounding metal of
the stove. Do not leave the stove unattended with air controls too far open.
2.
The fire door has been left open or the rope seal is worn, damaged or missing. This should be replaced if necessary or can be pulled out, adjusted and easily re-placed.
3.
Excessive chimney draw (the minimum flue draft for nominal heat output is:- not exceeding 0.15
mbar (0.06" water gauge)). If it is high use remedial action; either the fitting of a flue stabiliser to
the flue as close to the appliance as is aesthetically possible, the fitting of a flue damper in the chimney, or a chimney cowl. (Ask your dealer or contact us for details).
Chipboard and other composite wood-type materials contain corrosive additives, as do sulphurous coal
products especially when mixed with wet wood, these may etch and permanently damage the surface of the
glass.
