General Guidance

It is important that your stove is correctly
installed as Parkray Ltd 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 PERSON S SCHEME

Parkray Ltd 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.

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.

HEALTH AND SAFET Y 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.

MODIFICATI ON

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

JINCHW09 Rev A 12/05/14

long periods without first adjusting the controls to
a safe setting. Careful air supply control should be
exercised at all times.

FUME EMISSION

Properly installed, operated and maintained, this
appliance will not emit fumes into the dwelling.
The appliance door(s) must be kept closed at all
times, except for when de-ashing and refueling,
during which occasional fumes may occur.
However, persistent fume emission is potentially
dangerous and must not be tolerated.
If fume emission does persist, then the following
immediate action should be taken:-

1. Open doors and windows to ventilate the

room and then leave the premises.

2. Let the fire go out.

3. Check for flue or chimney blockage and

clean if required.

4. Do not attempt to re-light 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.

Adverse weather – In a small number of
installations, occasional weather conditions (e.g.
wind from a particular direction) may cause
downdraught in the flue and cause 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).

CO ALARM

Your installer should have fitted a CO alarm in the
same room as the appliance. If the alarm sounds
unexpectedly, follow the instructions given under
“Warning Note” above.

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 DIM ENSIONS

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

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.

JINCHW09 Rev A 12/05/14

This appliance will fit into a standard 16” fireplace
opening if the clay fire back is removed.

Any non-combustible walls within 50mm of this
appliance should be at least 200mm thick and
should extend at least 30mm 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 inter-connecting 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. Parkray Ltd 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 gas and electric fires and therefore not
suitable for solid fuel.

HEARTH REQUIREMENTS

A constructional hearth with a minimum thickness
of 120mm should be provided. This constructional
hearth should extend to at least 244mm in front
of the stove and 121mm 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 REQUIREMENTS

The flue serving this appliance must be dry, free
from cracks and obstructions and be in accordance
with relevant standards.
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.

The chimney/flue should have a vertical height of
at least 4.5 meters and should terminate in
accordance with Table 1.

JINCHW09 Rev A 12/05/14

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

Excluding some fire surround installations (see
below) there should be no combustible material
within 200mm of either side of the stove or
275mm above.

No combustible furniture should be placed any
closer than 700mm from the front of the stove.

FIRE SURROUNDS

Please check the suitability of any
fireplace/surround for closed solid fuel appliances
before installation.

Parkray Ltd 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.
