Installation and Operating Instructions

General Guidance

It is important that your stove is correctly installed as
Cleanburn Stoves cannot accept responsibility for any
fault arising through incorrect use or installation.
These instructions cover the basic principles to
ensure satisfactory installation of the stove, although
detail may need slight modification to suit particular
local site conditions.

The installation must comply with current Building
Regulations, national and European standards, Local
Authority byelaws and other specifications or
regulations as they affect the installation of the stove.
The Building Regulations requirements may also be
met by adopting the relevant recommendations in
the current issues of British Standards BS 8303 and BS
EN 15287-1.

COMPETENT PERSONS SCHEME

Cleanburn Stoves recommend that this stove is
installed by a member of an accredited competent
persons scheme e.g. HETAS.
If the installer is not a member of a competent
persons scheme, it is a legal requirement to notify
your local building control body in advance of any
work starting.

HEALTH AND SAFETY PRECAUTIONS

Special care must be taken when installing the stove
such that the requirements of the Health and Safety
at Work Act are met.

HANDLING

Adequate facilities must be available for loading,
unloading and site handling.

FIRE CEMENT

Some types of fire 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.

MODIFICATION

No unauthorized modification of this appliance
should be carried out.

Safety

WARNING – This appliance will be hot when in
operation and due care should be taken. The supplied
gloves may be used to open the door and operate the
air controls.

AEROSOLS

Do not use an aerosol spray on or near the stove
when it is alight.

FIREGUARDS

Always use a fireguard in the presence of children,
the elderly or the infirm. The fireguard should be
manufactured in accordance with BS8423 –
Fireguards for use with solid fuel appliances.

DO NOT OVER-FIRE

It is possible to fire the stove beyond its design
capacity. This could damage the stove so watch for
signs of over-firing. If any part of the stove starts to
glow red, the stove is in an over-fire situation and the
controls should be adjusted accordingly. Never leave
the stove unattended for long periods without first
adjusting the controls to a safe setting. Careful air
supply control should be exercised at all times.

FUME EM ISSION

Properly installed and operated, this appliance will
not emit fumes. Occasional fumes from de-ashing
and refueling may occur. Persistent fume emission
must not be tolerated.

This appliance should not be operated with the
doors open

If fume emission does persist then the following
action should be taken immediately;

 Open Doors and windows to ventilate room.
 Let the fire out, or eject and safely dispose of fuel

from the appliance.

 Check for flue/chimney blockage and clean if

required.

 Do not attempt to relight the fire until the cause

has been identified and corrected.

 If necessary seek professional advice.

ADVERSE WEATHER
In a small number of installations, occasional local
weather conditions (e.g. wind from a particular
direction) may cause downdraught in the flue and the
stove to emit fumes. In these circumstances the stove
should not be used. A professional flue installer will
be able to advise on solutions to this problem (e.g.
anti-downdraught cowl).

DO NOT FIT AN EXTRACTOR FAN IN THE SAME
ROOM AS THIS APPLIANCE.

IN THE EVENT OF A CHIMNEY FIRE -

 Raise the alarm
 Call the Fire Brigade
 Close appliance air controls
 Move furniture, ornaments etc away
 Place a fireguard in front of stove
 Check the chimney breast for signs of excessive

heat.

If the wall is becoming excessively hot, move
furniture away. Ensure the Fire Brigade can gain
access to your roof space in order to check for fire
spread.

Installation

APPLIANCE DIMENSIONS

FLUE OUTLET POSITION

The flue outlet angle is 30°. The effective centre
dimension is shown below.

AIR SUPPLY

The room or space containing this appliance should
have purpose provided ventilation (where necessary)
in accordance with Building Regulations.

Due consideration should be given to air
requirements for any other appliance in the same
room or space.

Any air opening must be kept clear from blockage or
obstruction.

APPLIANCE OPENING

FLUE CONNECTION - All inset installations must have a

‘Throat Forming Lintel’, if a ‘Builders Opening Lintel

is present then this will have to be modified for
these units to be fitted.

This stove must be fitted on a hearth or base with
adequate load-bearing capacity.
The opening into which this stove is fitted should be
constructed wholly from non-combustible materials.
The dimensions of the opening should be at least
those shown in the diagram.

This appliance will fit into a standard 16” fireplace

opening if the clay fireback is removed.

Any non-combustible walls within 50mm of this
appliance should be at least 200mm thick and
should extend at least 300mm above the top of the
appliance and at least 1.2 metres above the hearth.
Any walls more than 50mm from the appliance may
be reduced to a thickness of 75mm. Ensure the inter­connecting flue pipe also has adequate clearances to
combustible materials.

The walls surrounding the stove will become hot and
should therefore be finished in a heat resistant
plaster.

Do not hang pictures, plasma screen televisions or
ornaments above the stove, as these could be
damaged and could potentially create a fire hazard.

Please check the suitability of any
fireplace/surround for closed solid fuel appliances
before installation. Cleanburn Stoves cannot be held
responsible for any fault arising through incorrect
use or installation. Fire surround back panels
suitable for solid fuel are usually in three sections
and slabbed. Many fire surrounds are suitable only
for use with gas and electric fires and therefore not
suitable for solid fuel.

HEARTH REQUIREMENT S

A constructional hearth with a minimum thickness of
125mm should be provided. This constructional
hearth should extend to at least 300mm in front of
the stove and 150mm at the sides.

The constructional hearth should be made of solid
non-combustible material and can include any solid

non-combustible floor. The boundary of the hearth
must be clearly marked. This can be done by adding a
super-imposed hearth on top of the constructional
hearth – e.g. a slate slab on top of a solid concrete
floor.

FLUE REQUIREME NTS

The flue serving this appliance must be dry,
free from cracks and obstructions and be in
accordance with the designations shown in
Table 1.
The diameter of the flue should not be less
than 150mm and not more than 200mm.
If these requirements are not met the chimney
should be lined by a suitable method.
If there is no existing chimney then either a
prefabricated block chimney in accordance
with Building Regulations Approved Document
J or a twin-walled insulated stainless steel flue
to BS EN 1856 can be used. These chimneys
must be fitted in accordance with the

manufacturer’s instructions and Building

Regulations.

Table 1 – Minimum Flue Designations

The chimney/flue should have a vertical height
of at least 4.5 metres and should terminate in
accordance with Table 2.

If the chimney is believed to have previously
served an open fire installation, it is possible
that the higher flue gas temperature from the
stove may loosen deposits that were previously
firmly adhered, with the consequent risk of
flue blockage. It is therefore recommended
that the chimney is swept a second time within
a month of regular use after installation.

If you have any doubts about the suitability of
your chimney, consult your local
dealer/stockist.
Both the chimney and flue pipe must be
accessible for cleaning and if ANY part of the
chimney cannot be reached through the stove
(with baffle removed), a soot door must be
fitted in a suitable position.

FLUE DRAUGHT

If the draught exceeds the recommended
maximum, a draught stabiliser must be fitted
so that the rate of burning can be controlled
and to prevent over firing.

If the reading is less than the recommended
minimum then the performance of the
appliance will be compromised.

The flue draught should be checked under fire
at high output.

Minimum Draught – 1.2mm Water Gauge
Maximum Draught – 2.5mm Water Gauge

CLEARANCES TO COMBUSTIBLE MATERIALS
There should be no combustible materials for a
distance of 250mm either side of the stove or 325mm
above. No combustible furniture should be placed
any closer than 900mm from the front of the stove.

REMOVING INTERNAL COM PONENTS

All internal components must be removed prior to
fitting the stove. This will make handling the stove
easier; allow access to fixings and the flue outlet; as
well as protect the internal components from
damage during the installation process.

1. Open the door(s) and remove the ash pan.

2. Remove the fuel retainers by turning them

towards you until the pins at the ends of them
align with the cut-outs in the fuel retainer
supports and sliding them out.

3. Remove the fuel retainer supports by lifting them

free from the slots in the catch bar and swinging
the bottom ends out of the stove.

4. Slide the side bricks out.

5. Remove the rear bricks.

6. Remove the lower rear brick support using the

finger hole provided to lift it from its slots.

7. Cut the cable ties and remove the baffle by rolling

it up over the baffle supports and out of the stove.

8. Remove the grate bars, starting with the high

bars.

9. Remove the firebox side plates.
