1 Warnings
It is a legal requirement that the installation of all new or replacement,
wood or solid fuel heating appliances obtain Building Control approval from
your local authority. This can be done by using a qualied heating engineer,
aliated to a government approved Competent Persons Scheme such as those
listed on www.gov.uk/building-regulations-competent-person-schemes You can
also consult your local buildings inspector / controller.
All local regulations, including those referring to National and European
standards, need to be complied with when installing the appliance.
This stove should not be installed into a chimney that serves any other heating
appliance.
Any manufacturer’s instructions must not be taken as overriding statutory
requirements.
Arada Ltd will not be responsible for any consequential or incidental loss or
injury however caused.
Any further warnings in this document will be marked out in
a box such as this one. Ignoring the warnings could lead to
damage/injury to persons and/or property.
2 Health and Safety
Before any installation work is undertaken consideration must be given to the
Health and Safety at Work Act 1974. Safe working practices should be followed at
all times.
Please consult health and safety guidelines for advice on handling heavy and/or
large items.
During installation ensure that adequate precautions are taken to avoid
unnecessary risk to yourself or any householder.
BK605 Rev02 1

Cassette Stove Installation Guide
The danger from the caustic nature of re cement, should be avoided by using
these accepted methods: Wear gloves when handling re cement. Wear goggles
when chiselling or looking up chimneys.
This stove contains no asbestos. If there is a possibility of disturbing any
asbestos in the course of the installation then please seek specialist guidance
and use appropriate protective equipment.
3 Installation Requirements
3.1 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.
Hearths and recesses for Cassette stoves 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.
Cassette stoves should be installed into a recess on a non-combustible surface
not less then 125mm thick (conforming to Building Regulations) of suitable load
bearing capacity. Allowances should be made for the expansion and contraction
of materials which are tted up to and near the appliance.
Dimensions of the constructional hearth for all stoves (including any ’hole in
the wall’ type installation) 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.
BK605 Rev02 2

Cassette Stove Installation Guide
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
plastering 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.
When installing the stove into a recess it is important that the front outer
jacket edges sit 5mm proud of the wall surface to enable the trims to clip onto
the re.
3.2 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.
3.3 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.)
BK605 Rev02 3

Cassette Stove Installation Guide
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.
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 300mm2for 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.
For more detailed guidelines on required ventilation sizes please refer
to the Document J Building Regulations (Combustion Appliances) at the
www.planningportal.gov.uk 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.
BK605 Rev02 4

Cassette Stove Installation Guide
4 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 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.
BK605 Rev02 5

Cassette Stove Installation Guide
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.
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.

5 Installing the Stove
To make the stove easier to manoeuvre (thus safer) we recommend you remove
the following parts which can then be retted when the stove is in its nal
position:
•Grate Bars
•Liners
•Door (To help prevent the glass from breaking)
•Operating Tool
•Ash pan
•Throat Plate
5.1 Removing the door.
Open the door so that it is perpendicular to the stove body and then carefully lift
the stove door upwards of its hinges. To replace the door reverse the instructions
above.
5.2 Removing the throat plate and liners
The throat plate rests on both the side liners and tertiary air bar at the rear of
the rebox.
With the re door removed or open push up on the throat plate with the palm
of one hand. With the other, remove the side liners and then lower the throat
plate forward. It is easier to lower one side of the throat plate rst to help remove
it from its position and to allow it to t through the opening of the stove. Once
the throat plate has been removed you can also remove the rear liner(s).
To replace the liners/throat plate follow the steps above in reverse.
5.3 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.
BK605 Rev02 7

Cassette Stove Installation Guide
Figure 1: Bars shown seated on their comb outside the stove.
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.
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.
5.4 Fitting the spigot outlet to the stove
Please refer to the separate sheet (included) which details the installation of
the spigot to the stove body.
5.5 Connecting the spigot outlet to the ue system
The ue pipe must be tted inside the outlet spigot as shown in Figure 2 on
the following page. Failure to do so could result in the spillage of condensation
running down the ue.
BK605 Rev02 8

Cassette Stove Installation Guide
Figure 2: Fitting the ue pipe inside the spigot collar.
Fire cement should be used to create an airtight seal between the ue and
spigot.
5.6 Sealing the stove to the re surround
In order for the stove to operate correctly and at maximum eciency it is
necessary to achieve a good seal between the back face of the stove convector
section, the stove back base sections and the decorative re surround and
recess.
This should be achieved using re cement. Any void surrounding an inset
stove when installed should be lled with re cement in the interest of safety and
eciency.
5.7 Fitting the frame
Please refer to the instructions included with the frame for information on how
to t them.
6 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
BK605 Rev02 9

Cassette Stove Installation Guide
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.
•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 those referred to
at www.gov.uk/building-regulations-competent-person-schemes ), 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.
