INTRODUCTION

Cassee Stove Installaon Guide — BK605 Rev 04 5
Hearths and Recesses
The stove should be installed on a surface with
adequate load bearing capacity. If the exisng
construcon does not meet this prerequisite, suitable
measures (e.g. load distribung plate) should be taken
to achieve it. Please pay parcular aenon when
examining exisng building work for suitability to
meet the following requirements.
Hearths and recesses for Cassee stoves should have
a suciently at surface to allow a good seal to the
stove body to be created during its installaon.
Stonework, uneven bricks etc. may need further work
to ensure that this can be achieved.
Cassee stoves should be installed into a recess on a
non-combusble surface not less then 125mm thick
(conforming to Building Regulaons) of suitable load
bearing capacity. Allowances should be made for the
expansion and contracon of materials which are
ed up to and near the appliance.
Dimensions of the construconal hearth for all stoves
(including any ’hole in the wall’ type installaon)
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 combusble materials.
The superimposed hearth for all installaons 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
in a similar fashion to walls above radiators.
To help prevent this and cracking we recommend that
any plaster above the re should be ed 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.
Combusble Materials
Please view the product sheet which accompanied
your stove for specic minimum distances to
combusble measurements.
Ideally, adjacent walls should be of suitable non-
combusble construcon, preferably brickwork.
In large replaces take care that any supporng beam
is protected by a 13mm sheet of heat resistant re
board spaced 12mm o the surface with strips of non-
combusble material. Make sure that there is a gap
between an un-insulated ue system and any
combusble material. This gap must be at least 3X the
outside diameter of the ue pipe, or 1.5X the ue
diameter to non-combusble surfaces.
Please consult the ue manufacturers specicaon for
insulated ues.
INSTALLATION REQUIREMENTS

6Cassee Stove Installaon Guide — BK605 Rev 04
Air For Combuson
All stoves require venlaon 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 combuson into the room in which
the stove is installed. Air starvaon will result in poor
ue draw and may cause smoke to leak into the room.
For all installaons it is recommended that a
permanent vent with a total free area of at least
550mm2 for every kW above 5kW should be
connected directly to the outside air. Installaons in
properes built aer 2008 should have their vent
increased by a further 330mm2 for each of the rst
5kW. Alternavely 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 ed with a draught stabiliser
(or if one is ed 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 addional 850mm2 for each kW output over 5kW.
If there is more than one appliance in the property
then each appliance must be supplied with adequate
combuson air so that all appliances can be lit
simultaneously.
The posioning of any air vent must be so that it
cannot be liable to blockage or obstrucon. Ideally it
should also be posioned where it is unlikely to cause
a cold draught. It should not be posioned in the
replace recess.
For more detailed guidelines on required venlaon
sizes please refer to the Document J Building
Regulaons (Combuson Appliances) at the
www.planningportal.gov.uk website.
If you plan to use an external air supply on appliance,
all I Series cassee stoves are factory ed with an air
supply adaptor located on the base of the appliance
that will accept a exible pipe of a diameter 102mm
externally, see Fig. 1 and 4 for details.
The air duct ed must be of a minimum diameter of
100mm, non combusble and ducted to the outside in
a manner that will not eect the performance of the
stove.
No sharp bends and a maximum duct length of 10
metres is permissible.
Where the duct terminates on an external wall ensure
that there is no risk of blockage with leaves or
accidental placement of items, ensure there is no risk
of ingress of moisture or access for rodents.
Avoid ng the air inlet pipe through a wall that may
be unduly eected by prevailing winds that may cause
a sucon on the pipe bringing combuson products
back down the ue.
In extreme cases the placement of the terminal on the
external wall may pose problems and remedial acon
may be required to relocate the terminal or provide
two terminals on apposite walls to balance the wind
eect.
Where the stove is connected to outside air and there
is NO draught stabiliser ed, there is no requirement
for a addional air vent, provided a successful ‘smoke
draw test’ has been carried out as part of
commissioning.
INSTALLATION REQUIREMENTS

Cassee Stove Installaon Guide — BK605 Rev 04 7
NOTE : If a requirement of the installaon, a draught
stabiliser IS ed, then a permanent air vent will be
required and should be increased by 300mm2 for each
kW of rated output up to 5kW and an addional
850mm2 for each kW output over 5kW. Please refer to
Building Regulaons Part J (BS 8303 Part 1).
For further informaon on detailed guidelines on
required venlaon sizes, please refer to the
Document J or your local building control department.
Flues and Chimneys
The stove must be connected to a suitable and
ecient ue so that products of combuson (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 terminaon of the outlet at the top of
the ue also needs to comply with Building
Regulaons. The minimum eecve 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 0.2mb.
The draw of a chimney / ue can vary in dierent
weather condions 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 regulaons but could sll
be subject to down draught and similar problems. A
chimney terminang 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 Regulaons that
specify the requirements for solid fuel burning
installaons.
Suitable types of chimney include the following :

 Masonry Chimney: Built with clay or concrete
liners, or a chimney block system meeng
Building Regulaons. These types of chimneys
should be installed in accordance with the
Building Regulaons and BS EN 15287-2:2008
 Factory Made Insulated Chimney: Complying
with BS 4543:Part 2 (oen called Class 1
prefabricated metal chimney). These types of
chimneys should be installed in accordance with
Building Regulaons and BS EN 15287-2:2008.
Due to the gradual introducon of European Chimney
Standards chimneys will be specied according to
their performance designaon as dened in BS EN
1443 that covers the General Requirements for
chimneys. The minimum performance designaon
required for use with solid fuel burning stoves is T450
N2 S D3.
The ue and chimney installaon must be carefully
checked by a competent person before ng 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
addional checks and smoke tesng as described in
Appendix E of the Approved Document J 2010 Edion
should also be carried out to ensure the ue and
chimney are in good operang condion.
Check the exisng ue is in good condion with
suitable access for collecon and removal of debris.
It is also important that suitable ue pipe
(recommended at least 600mm in length) complying
with the Building Regulaons is used to connect the
stove to the ue in the chimney. Suitable access
should be provided into the ue for regular inspecon
and sweeping of the ue ways. The installer should
comply with Building Regulaons requirements in
respect of providing a Noce Plate giving details on
the chimney, ue lining, hearth and replace
installaon.
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 secon should not exceed 150mm in
length. If necessary a combinaon of 45° and 90°
bends can be used as long as the sum of their angles is
not greater than 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 lile output to the room, it is likely that excess
draw is present in the ue and that heat is being
sucked out of the appliance via the chimney.
To remedy this problem, we recommend ng of a
draught stabiliser in preference to a ue damper, in
the interest of safety and eciency, together with
insulang around the exterior of the appliance, this
will ensure heat loss into the fabric of the building is
kept to a minimum.
FLUES AND CHIMNEYS

Cassee Stove Installaon Guide — BK605 Rev 04 9
Installing The Stove
To make the stove easier to manoeuvre (and safer) we
recommend you remove the following parts which can
then be reed when the stove is in its nal posion:
 Grate Bars
 Liners
 Door (To help prevent the glass from breaking)
 Operang Tool
 Ash pan
 Throat Plate
Removing The Door
Open the door so that it is perpendicular to the stove
body and then carefully li the stove door upwards,
o  its hinges.
To replace the door reverse the instrucons above.
Removing The Throat Plate
And Liners
The throat plate rests on liners and (in some models) a
terary air bar.
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
posion 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.
Assembling The Grate Bars
In a mul 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 idencal.
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
secons of the comb rst by seang the ends marked
’L’ onto the low part of the comb, whilst the ends
marked ’H’ should then be seated on the high
secons.
In stoves with non-riddling grate systems the grate is
assembled with the ends of the bars marked ’H’ sing
on the front comb, and the ends marked ’L’ sing on
the rear comb.
Fig. 2: Bars shown seated on their comb outside the stove.
INSTALLING THE STOVE

10 Cassee Stove Installaon Guide — BK605 Rev 04
Connecng The Spigot Outlet To
The Flue System
The flue spigot outlet is inbuilt into the top section of
the appliance. The flue pipe must be fitted inside the
outlet spigot as shown in Figure 3. Failure to do so,
could result in the spillage of condensation running
down the outside of the flue.
Fire cement should be used to create an airtight seal
between the flue and spigot.
Sealing The Stove To The Fire
Surround
In order for the stove to operate correctly and at
maximum efficiency 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 fire surround and hearth.
This should be achieved using fire cement. Any void
surrounding an inset stove when installed should be
filled with fire cement, vermiculite or similar in the
interest of safety and efficiency .
Combustion Air Connection
If the installation requires the combustion air to be
take from the exterior of the building (Direct air), as
described earlier in this manual (page , then the
connection for this supply, is located on the base of
the appliance.
The connection hole is central to the appliance and is
90mm inboard from the rear of the appliance, as fig. 4
below.

INSTALLING THE STOVE
Sealing The Stove To The Fire
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
(rear body secon), the stove back base secons and
the decorave re surround and hearth.
This should be achieved using re cement. Any void
surrounding an inset stove when installed should be
lled with re cement, vermiculite or similar, in the
interests of safety and eciency.
Fing The Surround Trim
Please refer to the instrucons supplied with the
decorave trim, on the informaon on how to install
them.
Commissioning The Stove
Before handing over the installaon to the customer,
it is a requirement under Document J (of the Building
Regulaons for England & Wales) that the appliance is
lit and the funconing of the chimney system is
checked for sasfactory operaon.
 Be sure that the chimney is operang and all
smoke and fumes are vented to the
atmosphere through the chimney / ue
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—
20 pa, or 0.1 to 0.2 mbar.
