Congratulations on the purchase of your new Newbourne stove. Your new purchase will provide you with a
level of pleasure and comfort not previously experienced in your home.

The Newbourne is a heavy duty British designed multifuel stove.  It has been designed for easy installation and
ease  of  use  giving  a  lovely  flame  pattern  when  burning  wood  and  a  wonderful  warm  radiant  and  convection
heat.  The stoves are highly efficient with a clean burn firebox and efficiencies above 80% (Net) when burning
wood  and features  a curved  door, large  glass  window, vermiculite  insulated firebox, convector  top  plate,  bolt
on adjustable feet, ergonomic handle and heavy weight steel construction.

Please read and follow the advice and instructions on the safe and efficient operation of your stove to
ensure it has a long trouble free life and also read and follow the installation instructions before
installing the stove.

PART 1 OPERATING INSTRUCTIONS

A stove compared with an open fire is a very efficient heating appliance and must be installed and used safely
and wisely, it is important to understand the working of such an appliance and to understand the process of
converting the fuel into heat and its efficient transfer from the firebox to the room in order to gain the most from
the stove.

A stove creates an almost perfect environment to burn wood in.  The firebox will run at a very high temperature
ideal to burn the volatiles given off in the burning process and the  precise air controls allow minimal heat loss
into  the  flue.    Newbourne  stoveS  operates  at  an  efficiency  of  73  %

and 76% on a Gross CV basis (78-83%

Net) and is very much more efficient than an open fire avoiding the wasteful draughts normally associated with
that type of appliance

Burning wood is the natural way to store the sun’s energy to then be released in a carbon neutral process to
heat your house when the need is most. On a cold winters night there is nothing to beat the release of heat
and flame in a stove to raise the spirit.

The preparation and burning of wood as a fuel in stoves can be traced back many centuries, however it is a
forgotten or maybe never fully discovered activity in the United Kingdom, we have much to learn from our

Installation and Operating Instructions for Newbourne 35/40/50/60FS Multi Fuel Stoves

Ref: Pevex1022/AH/ver1:May2015

European and Scandinavian neighbours whose colder winters have instinctively led them into a natural wood
burning culture.

Wood for fuel is probably one of the most environmentally friendly energy sources, it is carbon neutral, trees
used for fuel production regenerate very quickly and it is a pleasant and satisfying job preparing the firewood
for the coming winters.

WARNING NOTE

Properly installed, operated and maintained this stove will not emit fumes into the dwelling.  Occasional fumes
from  de-ashing  and  refueling  may  occur.    However,  persistent  fume  emission  is  potentially  dangerous  and
must not be tolerated.  If fume emission persists, then the following immediate action should be taken:

a)  Open doors and windows to ventilate room and then leave the premises.
b)  Let the fire go out.
c)  Check for flue or chimney blockage and clean if required
d)  Do  not  attempt  to  relight  the  fire  until  the  cause  of  the  fume  emission  has  been  identified  and

corrected. If necessary seek expert advice

The most common cause of fume emission is flue way or chimney blockage. For your own safety these must
be kept clean at all times.

Any permanent air vent provided for combustion air must not be blocked off

There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to
emit dangerous fumes into the room.

Your installer should have fitted a CO alarm in the same room as the appliance. If the alarm sounds
unexpectedly then follow procedures a-d as shown above.

CHIMNEY CLEANING

The chimney should be swept at least once a year for smokeless fuels and a minimum of twice a year for wood
and  other  fuels.    It  is  important  that  the  flue  connection  and  chimney  are  swept  prior  to  lighting  up  after  a
prolonged shutdown period.  If the stove is fitted in place of an open fire then the chimney should be swept one
month  after  installation  to  clear  any  soot  falls  which  may  have  occurred  due  to  the  difference  in  combustion
between the stove and the open fire.

In  situations  where  it  is  not  possible  to  sweep  through  the  stove  the  installer  will  have  provided  alternative
means such as a soot door.  After sweeping the chimney, the stove flue outlet and the flue pipe connecting the
stove to the chimney must be cleaned with a flue brush.

It is possible to sweep through the Newbourne 35FS stove by removing the lower vermiculite baffle and upper
steel baffle to gain access to the flue pipe.  The method of removal is described later in the manual on page 8.

The connecting flue pipe and stove baffle should be checked monthly to clear any fly ash or soot
deposits.

USE OF A FIREGUARD

When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be
used to prevent accidental contact with the stove. The fireguard should be manufactured in accordance with
BS6539.

INSTRUCTIONS FOR USE:

First Firing

The stove has been treated with a heat-resistant coating, which hardens at a temperature of approximately
250

C. This hardening process causes the production of smoke and malodorous fumes, so the room must be

very well ventilated

During the first firing,

which should be carried out using approximately 1 kg of wood, the door must be left

slightly open and must not be closed until the stove is cold. This is to prevent the sealing rope sticking to the
stove.

RECOMMENDED FUELS

The recommended fuels that can be burnt on these stoves is wood logs and smokeless fuels of which we would
recommend ancit which is approved by Hetas.

Correct firing provides optimal heat output and maximum economy. At the same time, correct firing prevents
environmental damage in the form of smoke and malodorous fumes and also reduces the risk of chimney fires.

Installation and Operating Instructions for Newbourne 35/40/50/60FS Multi Fuel Stoves

Ref: Pevex1022/AH/ver1:May2015

Well seasoned woodfuel is essential for correct use.  Make sure your fuel is kept dry.  If the fuel is wet, a large
proportion of the heat will be used to vaporize the water, and this energy will disappear up the chimney.  It is
clearly not only uneconomical to fire with wet fuel but also, as mentioned above, increases the risk of producing
soot,  smoke  and  other  environmentally  damaging  by-products.   When  wood  is  used  as  a  fuel,  it  is  important
that it is  dry, i.e.  wood  with  moisture content  less  than 20%.   Ideally firewood needs seasoning for  at least 2
summers, logs should be stacked in a well ventilated situation, and logs over 100mm diameter should be split.
The stack should be protected from rain but remain well ventilated.

Generally dry wood (<20% moisture content) produces 4.5kW/h per kg; semi dry about 3kW/h per kg and wet
wood  1kW/h  per  kg  demonstrating  that  fewer  drier  logs  are  required  to  produce  the  same  amount  of  heat
output.

FUELS USED IN SMOKE CONTROL AREAS

In a building in a smoke control area you are legally only allowed to use this appliance to burn dry/seasoned
wood logs of the maximum length given above or authorised fuels. If you are unsure if your property is located
in a smoke control area or need further guidance on fuels you should contact your Local Authority.

MIXED FUEL USE

Use of brown coal and smokeless fuel

Uni-logs (brown coal brickettes) may be burned on the stove. Good performance will be obtained using these
brickettes. Approved smokeless solid fuels such as ancit may also be used. Avoid over firing. A mixture of
seasoned wood and smokeless fuel will provide extended burn times with a good flame picture.

USE OF BROWN COAL OR OTHER NON-AUTHORISED FUELS SHOULD NOT BE USED ON THE
APPLIANCE IF LOCATED IN A SMOKE CONTROL AREA UNLESS IT IS PART OF A MANUFACTURED
AUTHORISED FUEL.

It is essential when burning smokeless solid fuels that the ashpan is emptied on a daily basis. Ash must not be
allowed to build up below the grate. Note brown coal and smokeless fuel should also be stored dry and
ventilated.

Use of Petroleum coke, liquid fuels, house coal

and unauthorised fuels

will invalidate the guarantee and

must not be used

as this will cause the stove to “over fire” as well as damaging the internal components.

Operating at temperatures in excess of 500ºC will cause irreparable damage which is not covered by the
guarantee. B

urning any “contaminated” or treated wood which may have been painted, varnished,

oiled/stained or materials such as MDF or plywood which contain resins/glues should never be used as this will
cause an over-fire situation resulting in damage to the glass and bricks not to mention the toxic gases emitted
into the atmosphere. Also, never burn bituminous house coal which is designed for open fires and not for use
in stoves as this fuel is very volatile and gaseous containing lots of sulphur which will

permanently etch

marks in the glass

as well as potential damage to the bricks, baffles and grate.

Tested  according  to  the  requirements  of  EN13240  and  is  fully  assessed  and  considered  to  meet  UK  smoke
control requirements (see Appendix A).  Note that different fuel consumption results may be  achieved due to
other factors which include the fuel, chimney draught and atmospheric conditions etc.

The nominal output is the output to which the stove has been tested.  In practice, the stove burns with a heat
output range between its minimum and maximum ratings.

LIGHTING AND COMBUSTION

The  primary  air  is  drawn  into  the  stove through  the  air  slider located  on  the lower  part  of the  door;  slide  the
knob  to  the  right  to  allow  air  to  enter  and  slide  it  in  to  the  left  to  shut  off  the  air  supply.    Allowing    20%  of
primary  air  to  enter  is  a  recommended  position  during  normal  operation  of  the  stove  after  the  fire  has
established  in  the  firebox,  allowing  a  preset  bleed  of  air  to  enter.    In  practice  however,  you  may  find  it
necessary  to  reduce/increase  the  air  supply  depending  on  the  fuel  you  are  burning  and  the  draught  of  your
chimney.

The secondary air is regulated with the aid of a slider above the door; sliding it to the right increases the air
supply. The heated secondary air flows down the viewing wind

ow creating an “airwash” to keep the glass

clean and feeding the fire; it is this secondary combustion that completes the burning cycle by turning
unburned volatiles into flame. Finally, any remaining unburnt volatiles are burnt when preheated tertiary air
enters the firebox through the tertiary air diffuser at the rear of the firebox.

As much as half of the heat obtainable from wood is  achieved from secondary and tertiary combustion.  It is
important  that  the  firebox  temperature  is  maintained  at  a  high  level  as  this  also  aids  complete  combustion.
For example, when first lighting a stove it is important to get it really hot before closing the burning rate down.
The firebox temperature should reach 400°C which equates to approximately 250 °C at the flue pipe

The Newbourne stoves are designed and fully tested to burn extremely cleanly with very little smoke discharge
and are exempt for use in smoke control areas throughout the UK when burning dry  wood logs.  To comply,
built-in  permanent  stops  are  fitted  to  the  primary  air  control  so  that  it  cannot  be  closed  completely  and  will
always allow 1cm² of air to enter the firebox whilst the tertiary air allows a permanent 4cm² of air to enter.  A
permanent amount of primary air must therefore enter the firebox to feed the fire producing negligible amounts
of  smoke  and  unburnt  hydrocarbons.

The appliances will only be considered as exempt appliances if

these stops are in place.

When  burning  solid  fuel  it  is  recommended  that  the  secondary  air  slider  is  moved  fully  to  the  left  and  the
primary air slider is opened to allow air to be fed up through the grate and into the fuel.   The primary air slider
can be adjusted once the fuel is established to a position that gives the optimum level of comfort and heat.

LIGHTING THE STOVE

1. Put 2 small logs on a bed of ash spaced
about 6-7cm apart. Place some scrunched

up newspaper/paper with 1-2 firelighters in

between .

2. Neatly stack dry kindling on top of the logs

into approx 3 layers and light the bottom fire

lighters.

3a. Fully open top air slider

3b. And lower air slider and leave
the door slightly ajar to allow air
to enter and the fire to establish.

Installation and Operating Instructions for Newbourne 35/40/50/60FS Multi Fuel Stoves

Ref: Pevex1022/AH/ver1:May2015

Note

: If the fire dies down completely or embers are smoldering then it will be necessary to place some

screwed up paper  or firelighters onto the grate with some kindling or small pieces of wood to reestablish the
fire once again.  Leave the air sliders fully open and allow the fire to build before refueling with larger pieces of
wood and then adjust the sliders for optimum combustion.

Do not overload the firebox by loading above the tertiary air diffuser at the back of the firebox and
ensure that the wood is retained by the log guard. Always ensure that the wood is not tightly stacked
so that air can circulate freely.

Do not leave the door open: Operation with the door open can cause excess smoke. The appliance
must not be operated with the appliance door left open except as directed in the instructions.

Do not leave the airsliders completely open: Operation with the airsliders permanently open can cause
excess smoke. The appliance must not be operated with air controls or dampers left open except as
directed in the instructions.

SAFETY PRECAUTIONS

A risk of blowback can arise if too much dry wood is placed in the stove and burnt with insufficient combustion
air. This may result in the production of gaseous compounds which can ignite if the intake of primary and
secondary air is insufficient and the firebox temperature too low.

To  achieve  optimal  firing  and  the  best  possible  heat  output,  the  primary  and  secondary  air  intakes  must  be
correctly  adjusted.    As  a  general  rule,  the  fire  should  be  regulated  using  the  top  secondary  air  supply,  with
which  smoke  and  gases  are  ignited.    This  produces  a  high  level  of  efficiency  and  also  keeps  the  viewing
window clean because the secondary air ‘washes over’ the glass.

For woodburning it is an advantage always to leave some ash lying in the bottom of the combustion chamber.
Take care when emptying the ash pan, as cinders can continue to burn in the ash for long periods of time.

NOTE

: It is always advisable to leave the top air control open to allow the stove to operate to optimum

combustion.

MAINTENANCE OF MATT BLACK PAINT FINISH

The surface of the stove has been treated with heat-resistant paint.  The stove can be cleaned with a
soft brush after it has cooled down.  Any damage to the surface in the form of chips or scratches can
be  repaired  using  touch-up paint,  which  is  available  in  spray  cans.    If  the  stove  has  become  grey  in
colour  due  to  overheating,  touch-up  paint  of  this  kind  can  be  used  to  repaint  the  stove  entirely.
Alternatively  the  stove  can  be  maintained  with  a  traditional  type  of  stove  polish  of  which  there  are
several proprietary makes available

Do not use an aerosol spray anywhere near the stove when it is either

alight or still hot

– allow it to cool down before respraying.

MAINTENANCE OF THE STOVE GLASS

Incorrect  firing,  for  example  using  wet  wood,  or  slow  burning  can  result  in  the  viewing  window  becoming
covered  in  soot.    This  soot  can  be  easily  and  effectively  removed  by  using  a  damp  cloth,  proprietary  stove
glass cleaner or ash on a  soft cloth, when the glass is cold.  Burning contaminated, incorrect or fuels high in
Sulphur/pet coke may cause permanent damage to the glass (as described on page 3) which is not covered by
any warranty.

6.  Place  2/3  logs  on
the  ash  bed  ensuring
that  the  wood  is  not
stacked  too  closely
and  with  the  air
sliders  fully  open.
The  wood  will  ignite
in

2/3

minutes.

Gradually shut the
primary

air

and

adjust the secondary
air

for

optimum

combustion.

5.  After  about
40/50  minutes
and  when  the
last  flames  go
out  a  red  hot
ember

bed

will be left
and

further

wood can be
added.

4. With the door slightly
open

the

fire

will

quickly build warming
the stove and chimney.
After about 5/10 minutes
the door can be shut and
the

stove

can

controlled  by  the  air
sliders.  Shut  the primary
air slider and control the
burning  rate  with  the
secondary  air  to  give
optimal combustion.

OPERATIONAL PROBLEMS

In the event of smoke or malodorous fumes being produced, you must first check to see whether the chimney
is blocked.  The chimney must, of course, always provide the minimum draught necessary (12 Pa) to ensure
that  it  is  possible  to  regulate  the  fire.    However,  the  chimney  draught  may  also  be  affected  by  weather
conditions.  Both wind and temperature can affect the performance of a chimney.

In cases where the wood burns too quickly, this may be due to excessive chimney draught.  You should also
check to make sure that the door seal is intact.  If the stove produces too little heat, this may be due to the fact
that you are firing with wet wood.  A large proportion of the heat output will be used to dry the wood, resulting
in both uneconomical heating and an increased risk of soot and tar deposits forming in the chimney.

STANDING DOWN AT THE END OF THE SEASON

At the end of the burning season the stove should be prepared for the stand down period, this is to prevent
corrosion both in the stove and flue system.

The stove should be cleared of all ash, the baffle and flue ways cleared of soot and fly ash and the chimney
swept.

All air vents should be in the open position and it is recommended that the door is left ajar to ventilate the
chimney.

This is the ideal time to check for parts that may need replacing and to lubricate door hinges and catches.
Also it is recommended that all screws holding the glass in place are removed and replaced with a high
temperature lubricant.

PART II INSTALLATION INSTRUCTIONS

(for UK excluding Scotland where local Building

regulations must be conformed to).

It  is  essential  that  the  installation  is  carried  out  by  an  experienced  and  competent  installer  who  is  HETAS
registered  (see  www.hetas.co.uk)  and  with  reference  to  BS  8303,  Code  of  Practice  for  installation  of
domestic  heating  and  cooking  appliances  burning  solid  mineral  fuel.    Under  England  &  Wales  Building
Regulations  it  is  a  legal  requirement  that  the  stove  is  either  installed  by  a  competent  person,  which  is  an
installer who is HETAS Registered, or that the installation is carried out under Local authority building control
approval.

CO ALARMS

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  on  the  installation  of  the  carbon  monoxide  alarm  is  available  in  BS  EN  50292:2002  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.

When installing or servicing this stove care should be taken to avoid the possibility of personal injury

ASSESSING THE REQUIREMENTS FOR THE INSTALLATION OF A STOVE

Your supplier or Hetas registered installer will be able to advise you on the individual requirements that are
needed to install a stove safely.

It is most important that the stove is the correct size. This means that the output should match the heat
requirements of the room. Also to be considered is the fuel choice and the provision of suitable and
convenient storage with easy access to the stove.

Having  decided  on  the  ideal  appliance  then  the  installation  should  be  fully  assessed.  The  chimney
requirements should be carefully assessed.  Hearth requirements should be carefully specified, remember the
building  regulations  lay  out  the  minimum  requirements.  The  chances  of  damaging  a  floor  or  carpet  will  be
much reduced if the depth of a hearth is extended beyond the minimum.  Any combustible materials should be
at least 500mm distance from the sides and back and 800mm clear of the door and should never be allowed to
exceed 80 °C.  For further advice on chimney and hearth also see details below.

Assess also the fireplace surround if any is to be used, it is essential that combustible materials are not used
close to the stove and flue pipe. This requirement may vary depending on the construction of a stove but is
advised to keep combustible materials at least 500mm or preferably 1 metre away from the stove or flue pipe.

THE FOLLOWING ITEMS ARE INCLUDED WITH THE STOVE

A pair of leather gloves for operation of door handle and refueling the stove, an ashpan and handle .

HEARTH

The fireplace and hearth should conform to at least the minimum requirements laid out in the Building
Regulations Approved Document J. The hearth should be able to accommodate the weight of the stove and
its chimney if the chimney is not independently supported

Stoves must stand on a non-combustible hearth that must extend at least 300mm in front and 150mm to either
side and rear if the flue outlet is from the top.

DIMENSIONS AND CLEARANCES

No Combustible materials should be used in the construction of a fireplace or within the chimney or used in the
installation of a stove, flue or chimney.

Care should also be taken in the construction of hearths or fireplaces to ensure that suitable provision is taken
to allow for expansion and contraction of the construction materials.

When installing a Newbourne stove in a fireplace recess, sufficient space must be provided on either side,
behind and above to allow for heat convection and for access for maintenance of stove, flue pipe and chimney:

CLEARANCES FROM COMBUSTIBLES

when installing in a freestanding situation:



Recommended minimum clearance from front to combustible materials 800mm

It is deemed safe to install a Newbourne stove on a combustible floor provided it is covered by a non-
combustible hearth plate of at least 12mm thickness and extends at least 300mm in front and 150mm to either
side.

Note:

un-insulated flue pipe must be installed to local building regulations (we recommend that not more than a

1 metre length of plain un-insulated pipe is used before connection to a chimney system and that no
combustible materials are within 500mm of the flue pipe).

Baffle plate removal

The Newbourne stoves are fitted with a twin baffle system to improve efficiency and lower CO with the lower
one made from vermiculite and the upper one made from steel. Removal of the steel baffle allows immediate
access into the flue system for sweeping.

1. Removal of lower vermiculite baffle

2. Removal of upper steel baffle

Ref: Pevex1022/AH/ver1:May2015

CHIMNEY IMPORTANT WARNING

This stove must not be installed into a chimney that serves any other heating appliance.   The chimney must
be  a  minimum  height  of  4.5 metres  overall  height  and  be  in  accordance  with Building  Regulations  Approved
Document J and reference should be made to British Standard BS EN 15287-1:2007 design, installation and
commissioning of chimneys.  Any chimney, either masonry or a prefabricated stainless steel system must be
constructed and installed according to building regulations.  It is recommended that the minimum diameter of
the  flue  liner  be  150mm.    For  new  masonry  chimneys  we  recommend  pumice  cement  liners.    A  chimney
draught of at least .06” (12Pa or 1.5mm) is recommended.  If it is found that there is excessive draught in the
chimney then a draught stabiliser should be fitted.

Provision must be made for easy sweeping of the chimney. A soot door can be built into a masonry chimney
and flue pipe is available with cleaning doors.

Any bend in the chimney or connecting fluepipe should not exceed 45º and 90º bends should not be
used.

THE CHIMNEY CONNECTION.

The flue pipe for connecting the appliance to the chimney must be installed according to Building Regulations
Approved Document J and its diameter must be not less than the diameter of the outlet of the appliance. The
fluepipe must be adequately sealed to both the stove and the chimney to avoid any leakage.

We recommend also that no more than 1metre of plain un-insulated flue pipe be used to connect to the
chimney.

ALL CHIMNEYS SHOULD BE SWEPT AND INSPECTED BEFORE INSTALLATION OF ANY APPLIANCE

For relining existing chimneys 316 or 904 grade stainless  steel liners or pumice cement liners in accordance
with  Building  Regulations  Approved  Document  J  should  be  used.    Liners  should  be  suitably  insulated.  We
recommended  that  any  chimney  relining  is  carried  out  by  an  experienced  and  competent  installer  who  is
HETAS  registered  (see  www.hetas.co.uk).  The  HETAS  Guide  to  Approved  Products  and  Services  lists
Chimneys and lining systems suitable for use with solid fuel.

SWEEPING THROUGH NEWBOURNE.

When installed with a top flue outlet it is possible to sweep through the Newbourne Stoves. Remove the
baffles as described above, and access can be gained to the flue pipe.

VENTILATION

Purpose made ventilation is not required on the Newbourne 35 and 40FS for houses built before 2008.
Houses built after 2008 where the air leakage rate is less than than 5m3/hour/m

then a ventilator equivalent to

550mm

per kW output will be required

eg 4kW x 550mm = 2200mm

COMMISSIONING

The installer should carry out the following checks and ensure that the stove is fully functional. We strongly
recommend that a first firing is included in the commissioning process

1.  Check all flue pipe connections
2.  Check door latch mechanism

Appendix A

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).

Installation and Operating Instructions for Newbourne 35/40/50/60FS Multi Fuel Stoves

Ref: Pevex1022/AH/ver1:May2015

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) Order 1981, 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.

The

Newbourne Range

have been recommended as suitable for use in smoke control areas when burning

wood logs.

Your local authority is responsible for implementing the Clean Air Act 1993 including designation and
