INSTALLATION INSTRUCTIONS
Introduction
READ THESE INSTRUCTIONS CAREFULLY BEFORE STARTING THE INSTALLATION. CLOSE ATTENTION
TO THE DETAILS OF INSTALLATION WILL ENABLE YOU TO GET THE BEST RESULTS FROM YOUR
FIRE.
NOTE: THESE INSTRUCTIONS SHOULD BE RETAINED FOR FUTURE REFERENCE.
There are three essential requirements for a successful installation.
A. Theremustbecorrectlyttedintotherecessandsurround.
B. The chimney must be swept and of correct dimensions, be suitable for use with a wood burning stove and
be terminated clear of any possible wind effects.
C. There must be an adequate supply of air into either the appliance if an external air supply is used, or
adequate air supply into the room if an external air supply is not used.
Dimensions
TheTechnicalSpecicationsonpage5containsallthedimensionalinformationnecessarytoallowtheinstallation
to be properly planned.
Regulations
In the United Kingdom the installation must be in accordance with:-
●The Building Regulations issued by the Department of the Environment or the Building Standards (Scotland)
(Consolidation) Regulations issued by the Scottish Development Department.
●All relevant codes of practice and relevant parts of any local regulations, including those referring to National
and European standards Code of Practice BS8303 for installation of domestic heating and cooking appliances
burning solid mineral fuel.
●The current issue of BS EN 15287-1:2007 for design, installation and commissioning of chimneys must be
followed.
●In your own interest and for safety, in the United Kingdom, it is the law that all solid fuel appliances are
installedbycompetentpersons,aregisteredinstallerorapprovedbyyourlocalbuildingcontrolofcer.The
Heating Equipment Testing and Approval Scheme (HETAS) require its members to work to recognised
standards.
●In other countries the installation must also conform to the national and local regulations in force. This may
include only the use of permitted fuels in some countries.
Health and Safety Precautions
Special care must be taken when installing the stove such that the requirements of the Health and Safety at

Important Points to Note before Starting Installation.
Convection Inlet
Thismustneverberestricted.Therecanbettedonasmallplinthforaestheticreasonsalsothiswillhelp
prevent the ingestion of any ash from the hearth into the air inlet.
Paint
Itisstronglyrecommendedthatthereisprotectedfromcementandplastersplashesduringinstallation,as
thesearedifculttoremovefromthesurfaces.
Modular Construction
Due to the modular construction of the unit, you can for instance:
Fittheueconnector,airsupplypipesandtheouterbox.Therestofthecomponentscanbekeptinsafestorage
whileallroughbuildingandnishingworkisbeingcompleted.Atthenalstage,theengineandnishingframe
canbetted.
This way there is less chance of aesthetic damage, or accidental damage to important components while building
work is in progress.
Fire Cement
Sometypesofrecementarecausticandshouldnotbeallowedtocomeintocontactwiththeskin.Incaseof
contact wash immediately with plenty of water.
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.
Metal Parts
When installing or servicing this stove care should be taken to avoid the possibility of personal injury.
Installation Requirements
Anyunderoorventsoropeningswithin the builders opening should be sealed off.
Thesurfaceofthehearthandreplaceoormustbesufcientlyattoensurethatagoodsealwiththeouter
reboxcanbemadeandtoenablethenishingframetot.Anyexcessiveunevenness(uneventiles,stone,
etc.)shouldberectied.
Thefrontfaceofthereplaceshouldbereasonablyatovertheareacoveredbytheouterreboxtopandside
angesealstoensuregoodsealing.Thesefacesshouldbemadegoodifnecessary.
The appliance must not stand on combustible materials or carpets.
Unpacking
Handling - Adequate facilities must be available for loading, unloading and site handling.
Thereandthefollowingcomponentsarepackedinseveralcartons.Takecarewhenunpackingtheretoavoid
accidental damage. Particular care should be taken with the glass door and the air control mechanism.
Ensure that all the listed items are present before commencing installation.

Chimneys and Flues
Theueandchimneymustbeinspectedbeforeinstallationtoensurethatitissuitablefortheappliancebeing
tted.ChimneyanduesystemsmustmeettherequirementsoftheBuildingRegulationsDocumentJ.
Soundness of Flue
Theuemustbesoundandfreefromcracksandobstructions.Newuesshouldbelined.
All ues should be swept clean prior to installation and inspected for soundness and freedom from
blockages.
Anyuelinermustcomplywiththetestrequirementsforuelinersforusewithburningsolidmineralfuels.

Flue Size / Dimensions
Whetherthechimneyisoldorisnewlybuilt,itsdimensionsmustbeadequatetosupportthesizeofretobe
installed.Thelargerthere,thegreaterthesizeofueandthetallerthechimneyrequired.Whenspecifyingue
liners, ensure that the important internal dimensions are stated.
Theminimumheightofanyuemustbe4.5mmeasuredfromthetopoftheretothetopoftheue.Seethe
TechnicalSpecicationsonpage5forrecommendeduesizeandminimumchimneyheight.
Theuemustnotbeusedforanyotherapplianceorapplication.
Use of Existing Chimneys
Thesemustbesweptandinspectedfordimensionsandsoundnessbeforestartingtoinstallthere.Existingue
liners should be inspected and replaced if required.
Termination
It is important to terminate the top of the ue in such a way that it will allow free passage of combustion
products to the atmosphere without being subjected to turbulent air or high pressure zones that could cause a
downdraught.
Building regulations stipulate minimum clearance above windows and ventilation openings.
Potsshouldbesimple,opentoppedandwiththesameinternaldiameterastheue.Unconventionalpotsor
terminals must be so designed that will operate satisfactorily in all wind directions. Take steps to prevent birds
nesting in the terminal. Thatch roofs need specialist advice. Please contact your chimney supplier.
Flue Outlet
Flow from the outlet must be totally free from any obstruction.
Bends
Theidealueisstraightandvertical.Newchimneysmustnotdeviatemorethan45ºfromthevertical,butitis
desirablethatthedeviationsdonotexceed30º.Bendsgreaterthan30ºshouldbeavoidedwherepossible.In
olderchimneysbendsexceeding45ºmaybefoundandwilldegradeueperformance.
Sweeping
Thechimneycanbesweptthroughthere.Thereisprovidedwithremovablebafeboardstofacilitatechimney
sweepingandfortheremovalofsootfromtheunit.Theremustbeinstalledinsuchawaythatthiscanbe
carried out.
Flue Adaptor with Liner
Allresneedsometypeofadaptortoconnecttotheue.TheJetmasterueadaptorsuppliedmaybeattached
tothebaseoftheuelinerrstthenpushedupwhiletheouterreboxandinnerreboxareslidintoplace.
Afterthereisinstalledthen,workingfromtheinsideitshouldbepossibletopulltheadaptortogetherwithliner
downwardsintotherecessatthetopofthere.Ensurethatthegasketisttedbetweentheadaptorand
inner box as shown in photo.Onceithasseatedcorrectlythenthe3boltsmustbescrewedintothenutxings
to hold it in place.
TheJetmasterreisnotastructuralunit;althoughveryrobustitisnotdesignedtotaketheweightoftheue.
Therefore a structural lintel will need to be provided for clay liners or in the case of pre fabricated stainless steel
chimneythechimneymanufacturesrecommendedxingbracketsormethodmustbeused.
9

Flue Adaptor with Existing Flue
Ifthe existingue is tobe usedand theadaptor joined directlyto theue then theopening willneed tobe
preparedhighenoughtoallowtheouterboxadaptorandanyuepipetobeslidinplaceandwithsufcient

Donotinstallthisunitdirectlyontowoodenorcarpetoors.
Allowancesmustbemadeforexpansionandcontractionwhenttingmaterialsupagainsttherewhichmay

COMBUSTIBLE MATERIALS
Protection of Heat
Ason allheat producingappliances theuse of ammable wall coveringsand combustiblematerials directly
aboveortothesidesoftheremayleadtoarehazard.Pleasebearthisinmindwheninstallingtheappliance
or decorating.
Fire Surrounds and Shelves
If in doubt always consult the building regulations regarding the proximity of combustible materials.
Somere surroundsrequirethe reto be setforward from thechimney breastorto beraisedfor aesthetic
reasons.Ensurethattheserequirementsaretakenintoaccountwhenpositioningthere.Takethisintoaccount
whenformingtherecessandfrontnishedfaceofthereplaceforthere.Surroundsshouldbesuitablefor
usewithasolidfuelre.
Use the table below to achieve the minimum distances to combustible surrounds.
Model Min Height from frame of

In certain cases further protection may be required to guard against heat on combustible materials, such as
increasing the shelf height or shielding with a non combustible material.
Thisisbecauseofthevariabilityoftheheatproducedfromasolidfuelre.
It is dependent on the quality of fuel used and the refuelling frequency.
Pictures and TV’s
Duetotheextremetemperaturesthatcanbeachievedabovethere,alwaysensurethatanyTV’s,paintings
or other combustible items that may be near do not become excessively hot. For TV’s always consult the
manufacturer’s instructions to see if exposure to heat will cause damage.
Plastering
Hotaircancausestainingabovethereinthesamemannerasonthewallabovearadiator.
Thisoftenshowsmoreonlightercolourednishedsurfaces.
11

Theareadirectlyabovetherewillbecomeveryhot.Thereforetoreducetheriskofcrackingweadvisethe
following:
Whenplasteringabovethere,treinforcingmesh(expandedmetallathing)foratleast225mmabovethere
andforthefullwidthofthere.Thismeshcanbecontinueddownthesidesofthere.
Use a high temperature or other heat resistant plaster.
AIR SUPPLY
Allresrequireasupplyofairtosupportcombustionandtoallowthechimneytodrawcorrectly.
Airstarvationwillresultinpooruedrawandsmokinessintheroom.
All installations will require a permanent dedicatedairsupplyforthereofatleast5.5cm2per kW of rated
heat output over 5kW.ThesizeofairsupplyductorductsrecommendedforeachreisshownintheTechnical
Specicationsonpage5.
Anairsupplymayberequiredinhomeswhichhavehighlevelsofairtightnessevenifthereoutputis
5kW or less.
The Building Regulations Document J and L must be taken into account when providing ventilation for
there.
Newly constructed houses, especially those using double-glazing and employing modern draught control
techniques, will need careful planning of air entry.
Extractorsorfanswhenoperatedinthesameroomoradjoiningroomoftheremaycauseproblems.
If there is a fan or extractor tted in the property then allowance for additional air may be required. See
commissioning section.
If there is more than one appliance in the property then each appliance must be supplied with adequate
combustion air and ventilation so that all the appliances can operate simultaneously.
Air Supplied from Room
Bringairintotheroomclosetothere.Theidealpositionisjusttothesidesofthereplaceopeningasshown.
Itcanbesplitandbroughtupintwopositionsifrequired,oneeachsideofthereplaceopening.
Careful positioning of the vents is essential so that they are not liable to become blocked and cause cold
draughts.
Wherepossible,drawairfromtwowallsatrightanglesandducttoamixingchamberbeneaththeoorbefore
itenterstheroom.Thiswillreducetheinuenceofstrongwindsonthesupplyofair.Whereanexistingoor
is solid, vents may have to be provided through the walls in a manner, which achieves conditions as close as
possible to the above, perhaps, by the use of ducting or of false skirting.
Wherethereisasuspendedooroverawellventilatedunderoorspace,itmaybesufcientjusttosetventilation
openingsthroughtheoorboardsadjacenttothechimneybreast.Olderhouseswiththepossibilityofdraughts
enteringarounddoorsandwindowswillstillprotfromtheprovisionofaseparateairsupplyas,properlyplaced,
this will stop or reduce cold draughts.
DONOTsetaventilationgrilleinthehearthimmediatelyinfrontofthere.Thecoldairenteringtheroomwill
formacold‘curtain’infrontofthereandmaydestroytheconvectionofwarmairaroundtheroom.
DONOTplaceanairsupplyinletacrosstheroomfromthere.Thedraughtofcoldaircrossingtheroomwill
scourtheroomofwarmairandtheoverallheatingeffectoftherewillbereduced.
DO NOT set a ventilation grille in a position where they may become liable to blockage.
Wheretheoorissolid,ventsneedtobeprovidedthroughthewallsinamanner,whichachievesconditionsas
close as possible to the above, perhaps, by use of ducting or false skirting.
When bringing in the air supply consideration should be given to any regulations that would effect the position of
any ducting or ventilation grilles.

Air Supplied from External Source
The primary air can be taken from an external source from outside the building.
There is a knockout circular hole on the back of the outer box that will allow a 63mm exibleairpipetobe
pushed through the back of the outer box and over an adaptor sleeve and then over the air chamber pipe
attachedtotheinnerrebox.Anairkitisavailableasanoptionalextratodothis.
Withthisinplacetheexiblepipecanbefedthroughthewalloroortoanexternalairsource.Anopengrille
maybeattachedtotheendoftheexiblepipetostopdebrisfromblockingthepipe.Ensurethatthegrilledoes

Tertiary Air Tubes
Therearetwotertiaryairtubeslocatedatthetopoftheinnerreboxtobringairintothere.Oneislargeand
one is small. Each tube is held in its position by a swing cam catch attached with a single 8mm bolt to the left
handinnersideoftherebox.Thecamcatchhasalocatoratitsendthatlocatesinaholeattheendofthe
tube. When the cam catch locator is positioned in the tube hole the bolt is tightened to hold it in this position thus
trapping the tube. This ensures that the tube will not slide out and it keeps the tube with its tertiary air ports in the
correct position within the stove.
Abovethetwotubesare2setsofbafeboards.Thetwolowerbafesareloose,justrestingonthetubesand

Firstremovethefronttertiaryairtubeclosesttothedoorofthere.
To remove the tube, slacken the 8mm bolt using a 13mm spanner. Once the bolt is slack then the cam catch can
be rotated slightly so that the locator comes away from the tube hole releasing the tube.
There is no need to remove the 8mm bolt completely. It is easier for reassembly to just leave it loose.
8mm bolt holding cam latch Cam latch
Once this has been carried out then the tube can be slid across so that one end is released from the side
chamber to drop down allowing space to pull it out of the other side of the chamber.
Nextslideforwardthelowerbafesoverthereartubeanddroptheirfrontedgedownandremovethemfromthe

Oncethishasbeencarriedoutthentheupperbafecanberemoved.
Theupperbafeisheldinplacebetweenarecessedbracketinthebackpanelandabracketatthetopfrontthat
supportsit.Thebackoftheupperboardtsinarecessattherearofthestove.Thustheboardistrapped/rests
between the front bracket and the rear of the box.
Upperbafeboardandlocationbrackets
Toremovetheupperbafepulltheboardforwardoutoftherearrecessandlowertheboarddown.
This is achieved by lifting the front of the board up and at the same time pulling forward so that the rear of the
board “tongue” disengages from the recess bracket in the back panel. Then drop the rear of the board down,
17

lowering the front to clear the front bracket.
Note:Notoolsarenecessarytoremovetheupperbafe.
Replacement is the reverse procedure.
Removing and Replacing Ash Pan
Remove the ash pan by sliding it out from under the grid.
Fittheashpanbyslidinginunderthecastbottomgrid.Ensureitisttedthecorrectwayaroundwiththehandle
towards the front as shown below.
Bottom Grate Removal and Replacement
The bottom grate can be removed by lifting up at the back edge and lifting out.
The grate may need tilting sideways to clear the stove opening when removing.
Toret,reversetheprocedurebyinsertingthefrontedgeinrstandgentlyloweringthebackedge.
Internal Board Removal and Replacement (Rear and Sides)
The internal boards need to be taken out in the following sequence:-
IMPORTANT First remove the Ash Pan then the Bottom Grate followed by the Rear boards and then the Side
boards.
Although the boards are durable care should be taken not to break them during handling.
The position of the boards must be noted so that they can be replaced back in the same positions and order.
Notealsothatsomeoftheboardscanonlybettedonewayaroundorarehanded.
18

Rear Board Removal and Replacement
Removetherearverticalboardbygentlypullingthetopedgeoutrst,thenslideforward.
Replacement is the reverse procedure.
The rear board will need to be tilted/twisted sideways to clear the stove opening in a similar manner to the bottom
grate.
Side Board Removal and Replacement
Theleftandrightsideboardscanberemovedbygentlypullingoneedgeoutrstthen,slidetheboardstowards
the centre of the stove.
Replacement is the reverse procedure.
Toreplacetheboardsofferoneedgeinrstandthenpushtheboardgentlyback.
Note:Theyshouldbepushedbackatagainstthesteelbodyofthere.
Note:Someoftheboardswillonlytonewayaroundandiftheyareforcedwillbreak.
FlueAdaptorRemoval(Ifttedtore)
With the internal components removed it is now possible to get to the ue adaptor bolts.These should be
removedandtheadaptorcarefullyremovedfromthetopofthere.Takecarenottodamagetheadaptorseal.
Ifsomeoftheinternalboardsarestillinsituthencareshouldbetakenwhenremovingandreplacingtheue
adaptor bolts so that none of the internal parts become damaged.
Inner Firebox “Engine” Removal
Finallywiththeadaptorremovedtheinnerreboxenginecanberemoved.
Toremovetheinnerrebox,liftslightlyatthefronttodisengagethe2tagsthatlocatetheinnerboxintotheouter

FITTING THE FIREBOX
Due to the modular construction of the unit, you can for instance:
Fittheueadaptor,airsupplypipeandtheouterbox.Therestofthecomponentscanbekeptinsafestorage
whileallroughbuildingandnishingworkisbeingcompleted.Atthenalstage,theengineandnishingframe
canbetted.
This way there is less chance of aesthetic damage, or accidental damage to important components while building
work is in progress.
Flue Adaptor Connection to Flexi Flue
Theueadaptorcannowbeattachedtothebaseoftheuelineroruelineradaptor.Someadaptionmaybe
necessarytotheexistingueorlinertoenableittottotheadaptorsupplied.Thiscanthenbepushedupwhile
theouterreboxandinnerreboxareslidintoplace.Afterthereisinstalledthen,workingfromtheinsideit
should be possible to pull the adaptor together with the liner downwards into the recess at the top of the inner
rebox.Ensure theadaptor seal supplied is in place and then pull down the adaptor. Once it has seated
correctlythenthe3boltsmustbescrewedintothenutxingstoholditinplace.
Flue Adaptor Connection to Rigid Flue
Ifanexistingrigidornewueistobeusedandissuitablethentheadaptorwillneedtobejoineddirectlytothe
ue.Someadaptionmaybenecessarytotheexistingueorlinertoenableittottotheadaptorsupplied.The
openingwillneedtobepreparedhighenoughtoallowtheouterboxadaptorandanyuepipetobeslidinplace
andwithsufcientroomtoworktoenableconnectionbetweenreandueliners.
Thismayinvolvebreakingintothefrontofthechimneybreasttocreatesufcientspaceandttingtheouterand
inner box at the same time.
Outer Firebox Fitting
The box can be sealed to the opening using the insulation supplied, or similar insulating material.
Place the outer rebox in front of the prepared opening. Wrap the sides and back of the re with the bre
insulation and hold this in place with tape. Two layers of white ceramic insulation should be placed across
thetopoftheouterreboxrelievingaroundtheueadaptor.This is to allow for expansion and contraction
and to protect the wall above from excess heat.
Slidetheouterreboxintopositioninthepreparedrecess,takingcarenottosnagtheinsulationonthesides/
top of the opening.
