DEFRA Stove Installation and User Guide
2 Installation
2.1 Hearths and Recesses
The stove should be installed on a surface with adequate load bearing
capacity. If the existing construction does not meet this prerequisite,
suitable measures (e.g. load distributing plate) should be taken to achieve
it. Please pay particular attention when examining existing building work
for suitability to meet the following requirements.
When installing an inset stove, hearths should have a suciently at
surface to allow a good seal to the stove body to be created during its
installation. Stonework, uneven bricks etc., may need further work to
ensure that this can be achieved. Any voids behind an inset stove should
be lled with vermiculite or similar.
The stove should be installed on a non-combustible surface not less
then 125mm thick (conforming to Building Regulations unless otherwise
specied) of suitable load bearing capacity and heat resistance. Allowances
should be made for the expansion and contraction of any materials which
are tted up to and near the appliance.
Dimensions of the constructional hearth for all stoves should project at
least 500mm forward of the front of the appliance and 150mm at the sides.
The surface of the hearth should be free of combustible materials. The
superimposed hearth for all installations should project at least 225mm
forward from the front of the appliance and 150mm either side of the
edge of the appliance.
In most buildings with solid concrete or stone oors, the requirement will
be met by the oor itself, but mark the hearth to ensure oor coverings
are kept well away or use dierent levels to mark the hearth perimeter.
Please be aware that hot air can cause staining above the re in a similar
fashion to walls above radiators. To help prevent this and cracking we
recommend that any plaster above the re should be tted with reinforcing
expanding mesh for at least 220mm above, and the full width of the re.
You should also use a suitably heat resistant plaster which should be
BK575 Rev02 2

DEFRA Stove Installation and User Guide
allowed sucient time to fully dry before using the stove or cracking is
likely to occur.
2.2 Combustible Materials
Please view the product sheet which accompanied your stove for specic
minimum distances to combustible measurements.
Ideally, adjacent walls should be of suitable non-combustible
construction, preferably brickwork.
In large replaces take care that any supporting beam is protected by
a 13mm sheet of heat resistant re board spaced 12mm o the surface
with strips of non-combustible material. Make sure that there is a gap
between an un-insulated ue system and any combustible material. This
gap must be at least 3X the outside diameter of the ue pipe, or 1.5X
the ue diameter to non combustible surfaces. Please consult the ue
manufacturers specication for insulated ues.
2.3 Air for Combustion
All stoves require ventilation to burn safely and correctly. There are a
number of requirements that need to be met when installing a stove, for
example, allowing for the permeability of the house (air permeability is the
general seepage of air into the house via air vents, doors and windows
etc.)
There must always be a permanent means of providing air for
combustion into the room in which the stove is installed. Air starvation
will result in poor ue draw and may cause smoke to leak into the room.
For all installations it is recommended that a permanent vent with a
total free area of at least 550mm2for every kW above 5kW should be
connected directly to the outside air. Installations in properties built after
2008 should have their vent increased by a further 330mm2for each of
the the rst 5kW. Alternatively this air can be supplied through an external
wall of an adjacent room, which itself has to be connected to the room the
appliance is installed by a permanent vent of the same size.
BK575 Rev02 3

DEFRA Stove Installation and User Guide
Note: If the appliance is tted with a draught stabiliser (or if one is tted
to the ue pipe or chimney in the same room as the appliance) then the
permanent air entry opening (or openings) should be increased by 300mm2
for each kW of rated output up to 5kW and an additional 850mm2for each
kW output over 5kW.
If there is more than one appliance in the property then each appliance
must be supplied with adequate combustion air so that all appliances can
be lit simultaneously.
The positioning of any air vent must be so that it cannot be liable to
blockage or obstruction. Ideally it should also be positioned where it is
unlikely to cause a cold draught. It should not be positioned in the replace
recess.
The tting of an extractor fan in the same room as the
stove, or an adjacent room is not permitted. A spillage test
will be required to determine how any extractor fans may
aect the required size of ventilation requirements.
For more detailed guidelines on required ventilation sizes please refer
to the HETAS Guide which can be found on the HETAS website.
If you plan to use an external air supply on a suitable stove, and have
bought the appropriate Arada External Air Supply Kit, please refer to the
instructions included with the kit on how to install it.
The accompanying stove technical product sheet states whether or not
your appliance is compatible with a Direct Air Supply Kit.
2.4 Fitting the ue outlet
The ue outlet spigot may be tted onto the stove, but will not be fully
tightened.
The ue outlet assembly can be orientated for top or rear ue exit as
shown in gure 1 and 2 on the following page.
BK575 Rev02 4

DEFRA Stove Installation and User Guide
Figure 1: Fitting the ue outlet for a rear ue conguration.
Figure 2: Fitting the ue outlet for a top ue conguration.
The outlet pipe ange is pre tted with a gasket rope seal. Additional
re cement may be added if required.
The ue pipe assembly is secured in place with four M5 bolts (supplied).
Tighten bolts diagonally and evenly to ensure full compression of the gasket
but do not over tighten.
Place appliance on the hearth and make sure that it is level and does
not rock.
Connect the chimney ensuring all joints are sealed with re cement.
Note : The ue pipe must be tted inside the outlet spigot. Failure to
do so could result in the spillage of condensation running down the ue,
(see gure 3 on the next page)
BK575 Rev02 5

DEFRA Stove Installation and User Guide
Figure 3: Fitting the ue pipe inside the spigot.
2.5 Firebox liner panels
Arada DEFRA stove uses rebox liner panels at both sides of the stove.
The throat plate is not supported by these liners, however the throat plate
must be installed before the liners can be tted, and the liners removed
before the throat plate can be removed.
To remove / tting the liners:
•Open the re door.
•Remove the wood burning tray
•Remove the lower side liners, carefully allowing the upper side liners
to slide down to the landing plate
2.6 Fitting the throat plate
This must be carried out with the wood burning tray and side liners
removed.
All images below are cut-away for clarity
BK575 Rev02 6

DEFRA Stove Installation and User Guide
•Insert throat plate assembly into the re box and manoeuvre so that
the throat plate drops into the landing plate cut- outs.
•Raise the throat plate assembly vertically out of the landing slots
ensuring the front edge remains behind the front edge of the air
wash lip, see g 4.
•Hook the throat plate "T" cut-out onto the support hanger and push
back to slide onto the secondary air tube; the wood tray will hold
the bottom edge into the correct position.
Figure 4: Throat plate support and secondary air pipe.
2.7 Assembling the grate bars
In a multi fuel stove the grate comprises of a series of cast iron grate
bars, seated on a pair of combs. All bars in the grate are identical.
In stoves with a riddling grate system the bars should be seated with
every other bar rotated 180 degrees, so the ends marked ’H’ and ’L’
alternate on each comb. When assembling the grate, t bars to the low
sections of the comb rst by seating the ends marked ’L’ onto the low part
of the comb, whilst the ends marked ’H’ should then be seated on the high
sections.
BK575 Rev02 7

DEFRA Stove Installation and User Guide
Figure 5: Bars shown seated on their comb outside the stove.
In stoves with non-riddling grate systems the grate is assembled with
the ends of the bars marked ’H’ sitting on the front comb, and the ends
marked ’L’ sitting on the rear comb.
3 Flue and Chimneys
The stove must be connected to a suitable and ecient ue so that
products of combustion (fumes) from the stove are expelled to the outside
air. Please remember that chimney draught is dependent on four main
factors :
•Flue gas temperature
•Flue height
•Flue size
•Flue terminal
To ensure a good up draught it is important that the ue gases are kept
warm and that the ue size suits the stove. The termination of the outlet
at the top of the ue also needs to comply with Building Regulations. The
BK575 Rev02 8

DEFRA Stove Installation and User Guide
minimum eective height of the ue must be at least 4.5 metres from the
top of the stove to the top of the ue outlet. When warm the ue draught
should be between 0.1 to 0.2 mb.
The draw of a chimney / ue can vary in dierent weather conditions
and the customer should be made aware of this.
Failure to correct an over-drawing ue will invalidate the warranty.
A chimney may comply with regulations but could still be subject to down
draught and similar problems. A chimney terminating above the ridge level
is generally less likely to suer such problems.
If a new chimney is being provided it should fully comply with the relevant
Building Regulations that specify the requirements for solid fuel burning
installations. Suitable types of chimney include the following :
•Masonry Chimney : Built with clay or concrete liners, or a chimney
block system meeting Building Regulations. These types of chimneys
should be installed in accordance with the Building Regulations and
BS EN 15287-1:2007.
•Factory Made Insulated Chimney : Complying with BS 4543:Part 2
(often called Class 1 prefabricated metal chimney). These types of
chimneys should be installed in accordance with Building Regulations
and BS EN 15287-1:2007.
Due to the gradual introduction of European Chimney Standards
chimneys will be specied according to their performance designation as
dened in BS EN 1443 that covers the General Requirements for chimneys.
The minimum performance designation required for use with solid fuel
burning stoves is T450 N2 S D3.
The ue and chimney installation must be carefully checked by a
competent person before tting the stove to ensure it is suitable and will
work safely.
BK575 Rev02 9

DEFRA Stove Installation and User Guide
If the chimney is old (i.e: built of brick or stone without a liner) or being
opened up for reuse additional checks and smoke testing as described in
Appendix E of the Approved Document J 2010 Edition should also be carried
out to ensure the ue and chimney are in good operating condition.
Check the existing ue is in good condition with suitable access for
collection and removal of debris.
It is also important that suitable ue pipe (recommended at least
600mm in length) complying with the Building Regulations is used to
connect the stove to the ue in the chimney. Suitable access should be
provided into the ue for regular inspection and sweeping of the ue ways.
The installer should comply with Building Regulations requirements in
respect of providing a Notice Plate giving details on the chimney, ue lining,
hearth and replace installation.
Chimneys should be as straight as possible. Horizontal runs should be
avoided except where the rear outlet of the appliance is used, in which case
the horizontal section should not exceed 150mm in length. If necessary
a combination of 45 ◦and 90 ◦bends can be used as long as the sum of
their angles is not greater then 180 ◦in total. i.e four 45 ◦bends, or two
45 ◦and a 90 ◦bend.
If the stove appears to be working hard but produces very little output
to the room it is likely that excess draw is present in the chimney, and that
heat is being sucked out of the appliance and up the chimney. If this is
the case we recommend the tting of a draught stabiliser in preference to
a ue damper, in the interest of safety and eciency.
4 Commissioning the stove
Before handing over the installation to the customer it is a requirement
under Document J (of the Building Regulations for England and Wales) that
the appliance is lit and the functioning of the chimney system is checked
for satisfactory operation.
•Be sure that the chimney is operating and all smoke and fumes are
vented to the atmosphere through the chimney terminal.
BK575 Rev02 10

DEFRA Stove Installation and User Guide
•Check all joints and seals.
•Clean the outside of the cold appliance with a lint free cloth or shoe
brush to prevent any stains becoming burnt on.
•Check the ue draught which should read 10 - 20pa, or 0.1 - 0.2 mbar.
Consult a suitably qualied person who will have the knowledge and
equipment to perform a test.
•For a registered competent persons scheme, such as HETAS, please
complete a Certicate of Compliance, which is used for checking and
reporting the installation as imposed by the Government. Otherwise
please ensure the installation is approved by your local building
control ocer.
•Ensure a Carbon Monoxide alarm is tted. This must be between
1m to 3m from the appliance, and approximately 150mm below the
ceiling level.
•A reguard conforming to BS 8423:2002 should be used in the
presence of children or inrm people.
•A notice plate should be provided containing information on the
performance characteristics of the hearth, replace, ue or chimney.
•Explain the following to the customer:
How to operate the riddling mechanism and air control lever.
The importance of an adequate air supply to the room.
The importance of regularly having the chimney swept /
inspected.
That a protective glove should be used when operating the
stove.
How changes in the weather can eect the performance of the
stove.
Using the correct fuels.
5 Before using your stove
Arada stoves are designed to be operated with the re door(s) closed at
all times, apart from refuelling (when alight) or cleaning (when cold).
BK575 Rev02 11

DEFRA Stove Installation and User Guide
Never leave the appliance unattended for an extended length of time
with the door(s) open.
Prior to lighting the stove for the rst time, please check with the
installer that:
•Installation and all building work is complete. (Refer to the installation
guide.)
•The chimney is sound, has been swept and is free from obstruction.
•Building Regulations and any local by-laws have been followed during
installation.
•All rebox liner panels and throat plate are in place.
•The chimney draw has been checked and is within specication
(between 0.1mb to 0.2mb, or 10-20 pascals). This ensures your stove
will operate predictably and eciently.
•A Carbon Monoxide detector is correctly installed in the same room
as the appliance.
Ensure that you have read and understood these instructions before
lighting the re.
Our YouTube channel www.youtube.com/user/aradastoves features a
collection of videos designed to help you get the best from your Arada
stove.
Always wear suitable protective re gloves when refuelling your stove,
such as the Arada glove supplied with your stove.
We recommend that you light a small re for the rst few days of use
to cure the paint and allow the castings to relax. During this process the
paint surface may smoke briey, and you may smell a slight odour for an
hour or so. The vapour is harmless and should not be confused with fume
emissions, however, it is advisable to keep the area well ventilated until
the vapour disperses.
BK575 Rev02 12

DEFRA Stove Installation and User Guide
You may hear your stove produce clicking or ticking noises whilst it
heats up or cools down. This is completely normal and is produced by the
expansion and contraction of the steel components in your stove when its
temperature changes.
5.1 Warning - Fume / Smoke emissions
Warning: Properly installed, with a suitable ue or chimney,
operated and maintained correctly, this appliance will not
emit fumes into the dwelling.
Occasional fumes when de-ashing and refuelling may occur.
However, persistent fume emission is potentially dangerous
and must be investigated by a HETAS registered installer.
Stop using the appliance if you smell fumes or see
smoke escaping.
If fume emission does persist, the following immediate
actions should be taken:
•Open doors and windows to ventilate room.
•Let the re die or extinguish and safely dispose of
fuel from the appliance.
•Check for ue or chimney blockage, and clean if
required.
Seek expert advice from your HETAS registered installer. Do
not attempt to re-light the re until the cause of the fume
emission has been identied and corrected.
5.1.1 Refuelling on to a low re bed
If there is insucient burning material in the rebed to light a new fuel
charge, excessive smoke emission can occur. Refuelling must be carried
out onto a sucient quantity of glowing embers and ash that the new fuel
charge will ignite in a reasonable period. If there are too few embers in the
BK575 Rev02 13

DEFRA Stove Installation and User Guide
re bed, add suitable kindling to prevent excessive smoke
6 Advice on fuel types
6.1 Wood
As a natural and renewable fuel, wood is the rst choice for burning,
however burning wood requires a little eort and planning.
Any type of wood is suitable (though hardwood is preferable) provided it
is well seasoned and has a moisture content below 20%. This usually
implies that the timber has been suitably stored to allow moisture to
evaporate for at least 9 months in the case of soft wood, and at least
24 months in the case of hard wood. We recommend that for general
burning, wood should be split into logs of no more than 100mm (4 inches)
diameter.
If, when burning wood, you see signs of sticky tar inside the appliance
or chimney, your wood is ‘green’or too wet and requires further seasoning.
An electronic moisture meter can be obtained in order to determine the
moisture content of your wood fuel.
Paper will burn successfully. Burn dry paper only or chimney damage
will occur.
Wet wood must not be used as this will greatly contribute
to the creation of tar and creosote which may, in extreme
cases, run down the chimney in liquid form. This will
seriously damage both the chimney and the appliance and
increase the risk of a chimney re.
6.2 Clean burning of wood
In order to burn wood cleanly, in accordance with the DEFRA exception
certicate applicable to this stove, it is important that the Ignition and
Re-fuelling instructions are followed carefully.
BK575 Rev02 14

DEFRA Stove Installation and User Guide
7 Air controls
Our DEFRA stoves have one air inlet control for easy operation.
The air inlet provides air through the base of the stove, via the control
slider located under the base of the door.
The air passes from the base of the stove, through a sealed airway,
around the back and top of the re box providing a very hot air ow over
the re bed.
Secondary air also enters the re box through a pre-set bleed at the
rear of the stove, and is heated and distributed through the throat plate
arrangement.
The air control is fully adjustable but has two main settings in normal
use.
