The Clean Air Act 1993 and Smoke Control Areas
DEFRA
EXEMPT
Under the Clean Air Act local authorities
may declare the whole or part of the
district of the authority to be a smoke
control area. It is an offence to emit
smoke from a chimney of a building,
from a furnace or from any fixed boiler if
located in a designated smoke control
area. It is also an offence to acquire an
"unauthorized fuel" for use within a
smoke control area unless it is used in
an "exempt" appliance ("exempted"
from the controls which generally apply
in the smoke control area).
In England appliances are exempted by
publication on a list by the Secretary of
State in accordance with changes made
to sections 20 and 21 of the Clean Air
Act 1993 by section 15 of the
Deregulation Act 2015. Similarly in
Scotland appliances are exempted by
publication on a list by Scottish
Ministers under section 50 of the
Regulatory Reform (Scotland) Act 2014.
In Northern Ireland appliances are
exempted by publication on a list by
the Department of Agriculture,
Environment and Rural Affairs under
Section 16 of the Environmental Better
regulation Act (Northern Ireland) 2016.
In Wales appliances are exempted by
regulations made by Welsh Ministers.
• The Woodpecker range
(WP4/WP4LS/WP5) has
been recommended as
suitable for use in smoke
control areas when
burning wood. As such,
when the secondary
slider is in the closed position it
remains open by 8mm(WP4/WP4LS)
& 10mm(WP5) and is prevented from
closing by a screw.
Further information on the requirements
of the Clean Air Act can be found here:
www.gov.uk/smoke-control-area-rules
Your local authority is responsible for
implementing the Clean Air Act 1993
including designation and supervision of
smoke control areas and you can
contact them for details of Clean Air Act
requirements.
CO Alarms
It is required by building regulations that
whenever a new or replacement
wood/solid fuel or biomass appliance is
installed in a dwelling a carbon monoxide
alarm to BS EN 50292:2002 must be fitted
in the same room as the appliance.
The alarm should be installed according
to the alarm manufacturers instructions
and should not be considered a substitute
for the appliance being installed
incorrectly or regular maintenance of the
appliance or flue system by a competent
person.
Woodpecker range install manual 0720-4 21/07/2020 10:25 Page 6

Installation Instructions
Location of the unit
The appliance must stand on a level,
non-combustible hearth with a minimum
thickness of 12mm.
The Woodpecker range of stoves has
been tested and approved for use with a
superficial hearth, therefore the hearth
temperatures are below 100°C and the
use of a constructional hearth is not
necessary.
The superficial hearth must extend fully
beneath the appliance and extend
150mm to either side and 225mm in
front of the appliance.
The hearth should also incorporate a
clearly defined edge (change of
level/clear demarcation line) to
discourage the placement of
combustible materials within the hearth
area.
The hearth and building construction
must be of a suitable material to comply
with current building and local authority
regulations.
The fabrication of the construction must
have a suitable load bearing capacity for
the appliance and hearth.
If in any doubt, please consult a
competent person for advice before
proceeding.

Ventilation
Requirements
Building Regulations document J states
that purpose provided permanent
ventilation is not required in England
and Wales unless the appliance nominal
rated output is greater than 5kW.
The Woodpecker range of stoves have a
nominal output of 5Kw and therefore do
not require additional ventilation, unless:
• The air permeability of the building is
less than 5.0m³/ (h.m²), then 550mm
of permanent ventilation/Kw of the
nominal output is required as per
Building Regulations document J.
• If the appliance is installed into or
adjacent to, a room containing an
extractor fan then additional testing
and ventilation is required in line with
Approved Document (A.D.) 1.21
If difficulty in starting the fire or any
excessive fuming is experienced,
ventilation may be used in place as
required to eliminate these flue
problems.
If a flue draught stabiliser is fitted then
extra ventilation is required. See
Document J of the Building Regulations
for detailed guidance especially in new
build properties which often require
purpose provided ventilation be added.
Outside direct combustible air
connection
The Woodpecker range of stoves are
supplied with the ability of using a
dedicated 80mm diameter direct
connection duct through a suitable route
to the outside air. It can be connected to
the rear of the stove and should be
fitted at the time of stove installation.
Only the approved kit for ACR stoves
should be used (DA100)
This is designed to supply all the
necessary air(Primary, Secondary and
Tertiary) for safe combustion and
operation of the stove.
Providing there is no depressurisation of
the property by mechanical or other
types of ventilation, the flue, chimney
and ventilation duct are working
correctly, and properly maintained clear
of obstructions or leaks etc.
The kit supplies all the primary,
secondary and tertiary air to the stove
and may be used where mechanical
ventilation and heat recovery (MVHR)
units are used.
Some additional instructions for
installation are provided with the
dedicated kit supplied.
NOTE: in order to register the
installation with HETAS/Building
Control as of 2016 certain extra
testing and certification is required
if using an outside air connection.
Flue Draft
A flue draught at the flue collar of the
appliance with a minimum reading of
2.2mm to a maximum 3.5mm water
gauge (22 to 35 Pascals) is required for
satisfactory appliance performance.
This relates to 12-25 Pascals at the
tapping on EN13240/13229 test rigs
which is often quoted.
The Woodpecker range requires a
minimum of 12Pa within 3 minutes of
ignition (with the stove door closed) for
correct combustion.
The flue draught should be checked
under fire at start up and high output, if
the values fall outside of the stated
parameters then remedial works should
be carried out.
If it greatly exceeds the recommended
maximum, a draught stabiliser must be
fitted in line with building control
document J so that the rate of burning
can be controlled to prevent overfiring.
8
Woodpecker range install manual 0720-4 21/07/2020 10:25 Page 8

Flue Requirements
The flue must comply with current
Building Regulations Document J.
The Woodpecker range of stoves have
an internally removable baffle, and
therefore are able to be swept through
the appliance.
The construction of masonry, flue block,
insulated flue systems and flexible flue
liners must comply with the
manufacturers instructions at all times.
The flue must be:
A 150mm flue diameter is
recommended, 125mm may be
used if the appliance still has its
smoke exempt stop in place
In sound condition and provide
sufficient draft (minimum 12Pa
within 3 minutes of ignition) and a
minimum of 22Pa at high output
level
Suitable for use with solid fuel
burning appliances
Be able to clean the entire length of
the flue system without removal of
the appliance
Free from deposits
Well insulated
At least 3.5m in height from flue
collar to termination, with no more
than 4 x 45º bends in any one flue
system and have a maximum
horizontal length of no more than
20% of the overall vertical height
The termination should be sited as
to avoid a negative pressure zone
The flue must not be:
Shared with other appliances
Weight bearing on the appliance
A smaller diameter than the
appliance flue collar size (125mm)
Rear flue installations
The Woodpecker range of stoves is
capable of a rear flue option.
If this is a preferred flueing option, then
careful consideration should be given to
minimising the horizontal length of flue
from the appliance collar to where the
flue-way transitions to vertical.
Building regulation document J states
that a maximum horizontal length of
150mm is permissible, however up to
450mm is acceptable providing that a
flue draft calculation is completed and
approved, by both the manufacture of
the flue components and the appliance
manufacturer in writing.
This documentation must accompany a
successful flue draft test as stated
above and inline with Building
regulations document J.

Clearances to
combustible materials
If using single wall flue pipe, there must
be a clearance of at least 3 times the
diameter of the flue pipe (e.g. 125mm
diameter pipe = 375mm minimum
clearance) from any combustible
materials e.g. wooden beam, this can be
measured using a “line of sight” This
distance may be reduced by using an
appropriate heat shield in line with
Building regulations document J and
maintaining a 12mm air gap between the
shield and the combustible material.
Curtains and soft furnishings should be a
minimum of 1m away from the appliance.
Adequate space should be provided for
servicing the appliance.
Please be mindful of heat transfer to
electronic devices and artwork hung over
the fireplace.
Please remember that this appliance has
been designed to provide heat and if
installed into a recess enough space
should be left around the appliance to
enable the heat produced to rise and
escape from the recess back into the
room.
Clearances to non-
combustible materials
The Woodpecker range of stoves can be
recessed into a suitably sized, non-
combustible fireplace or stood close to
non-combustible materials.
However a permanent free air gap of at
least 50mm is recommended to be left
at each side, 150mm above and at least
50mm at the back of the stove to obtain
reasonable heat output and for access
to the stove for removal, maintenance
and servicing.
A clearance of 150mm to each side will
give a better heat output and facilitate
any remedial works to be undertaken.
For a corner installation the same
guidelines apply but consideration
should be taken to allow the door to fully
open.
To calculate the distance from the glass
to any combustible materials please see
the below combustible material chart.
In accordance with Building Regulations
document J all non-combustible walls
closer than 400mm to the stove should
be at least 75mm thick. Please refer to
Building Regulations document J for all
other stipulations regarding building
structure.
Clearances
Woodpecker range install manual 0720-4 21/07/2020 10:25 Page 10

11
To achieve minimum clearances as above, an integrated, insulated appliance connector,
such as the Midtherm HT-S Starter length must be used. When installing such an adaptor
please ensure that a minimum of 10mm gap is left between the top casting and the adaptor
for expansion and maintenance purposes.
If a single walled flue system is used then the Minimum distances to combustibles
increases to:
WP4/WP4LS • Rear Wall: 450mm • Side Wall: 550mm
WP5 • Rear Wall: 450mm • Side Wall: 600mm
WP4 / WP4LS twin wall flue WP4 / WP4LS corner twin wall flue
WP5 twin wall flue WP5 corner twin wall flue

Operating Your Stove
Recommended Fuels
Wood: hardwood such as ash, oak and
beech which have been cut for at least 2
years and stored under shelter. The logs
should have a maximum moisture content
of 20%. Maximum log length 400mm,
maximum width 125mm.
Smokeless solid fuel: below 20%
petroleum based coke (WP5 only).
Prohibited Fuels
Green wood: i.e wood which is less than
2 years old with a moisture content of
above 20%.
Recovered wood: i.e pallets, railway
sleepers etc. These will have been
chemically treated and will pollute the
atmosphere and possibly overheat the
appliance.
Housecoal or Bituminous coal: these
fuels will soot up the airways of the stove
and possibly overheat the appliance.
Petroleum Based Coke: over 20%
content - this will overheat the appliance
and possibly damage the unit.
Liquid fuels
Paraffin fire lighter blocks: these can
cause damage to the glass of your
appliance
Important note
You may also experience fumes and a
haze being given off by the stove during
the first firing and possibly for the next
couple of firings as the paint cures. This is
normal but please ensure that the room is
well ventilated during this period.
In the rare event of a malfunction due to
overheating or a chimney fire, the air slides
should be shut down completely and the
fuel allowed to burn out. In the event of a
chimney fire, once the air control has been
closed completely, dial 999 for assistance.
If the appliance has overheated, the
appliance and flue will need to be
inspected for any damage before it can be
operated again.
Using your appliance for the
first time
• To allow the appliance to bed in, and
fixing glues and paint to fully cure, only
fire the appliance using kindling and just
get hot for at least three fires.
• Before lighting the next small fire please
allow the appliance to return back to
room temperature.
• During these first small fires you may
experience a haze and unpleasant smell
as the paint cures, do not touch the paint
and keep the room well ventilated.
Please note that during the first firing, we
recommend a small fire is lit and that you
slowly increase the temperature to enable
the various parts to expand normally.
Always ensure that the ash drawer is fully closed before operation
of the appliance
Always check with your dealer or
directly with the manufacturer as
using the incorrect fuel may
invalidate your guarantee and
damage your appliance.

Re-fueling
When re-fuelling the stove always
refuel onto a bed of hot embers, fully
open the air control sliders until the new
fuel is well alight, before adjusting the
air control for the desired setting.
If there is insufficient burning material in
the firebed to light a new fuel charge,
excessive smoke emission can occur.
Refuelling must be carried out onto a
sufficient 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 fire bed, add
suitable kindling to prevent excessive
smoke.
Fuel overloading
Never overload the stove - it will work
very well with two medium sized logs.
The amount of fuel specified in this
manual should not be exceeded,
overloading can cause excess smoke
and may cause products of combustion
to spill into the room.
Stove slumbering
The Woodpecker range of stoves has
been designed and tested as an
intermittent wood burning appliance.
Under no circumstances should this
appliance be operated as a slumber
style of stove or for continuous
overnight burning.
This may cause damage to the
appliance and cause excess smoke and
pollutants to enter the atmosphere.
Glass
Never operate the appliance if the glass
panel is broken or cracked. This can
cause the appliance to overfire, which
may damage the appliance and flue
system and may cause a danger to
persons and property. Only use once
the glass is replaced and the sealing
gaskets checked for integrity. Only
replace with a manufacturers approved
glass.
• Note - if the stove is fitted with a
smoke exempt stop it will prevent the
secondary air control lever from fully
closing.
• Care should be taken to ensure that
the logs are not placed where there is
a danger that they may fall onto the
glass or out of the chamber when the
door is opened.
• Never load logs into the appliance that
are oversized or too long for the
combustion chamber, they could press
against the glass and cause damage
when alight. The maximum log length
is 300mm
• Never empty the ashes when the
stove is in operation, always wait until
the stove had burned out and cold.
• NEVER leave the ashes inside the
building, this can cause dangerous
levels of harmful Carbon Monoxide
to form in your home

instructions.
Dampers left open
Operation with the air controls or
appliance dampers open can cause
excess heat within the appliance. The
appliance must not be operated with air
controls, appliance dampers or door left
open except as directed in the
instructions.
Never leave the stove
unattended until the new
fuel is well alight.
Persistent fume emission is
dangerous and must be
investigated.
If fume emission persists, open doors
and windows to ventilate the room and
let the fire die out. Have the chimney
inspected for blockages and clean if
required. Do not relight the fire until the
cause has been found. We recommend
that you seek professional advice.
This appliance has been designed to be
burned with the door closed at all times
other than when refuelling.
It should not be operated as an open
fire.
• Typical refuelling intervals for wood is
1 hour.
• Typical refuelling time for Smokeless
fuel is 1.5 hours.

Maintenance
Daily Maintenance
• The grate should be cleaned regularly
and the ash pan emptied daily.
Never allow the ash in the ashpan to
overfill allowing ash to be in contact
with the underside of the grate.
This will overheat the grate and cause
premature wear and distortion.
• The glass can be cleaned using a soft
damp cloth or a stove glass cleaner
(ACR Glassbright cleaner is available
from your local ACR stockist).
• Do not clean the glass of your stove
with abrasive cleaners or scratch pads
as this may damage the surface of the
glass causing it to weaken.
• Never allow the door gasket to
become wet when cleaning the glass,
this will deteriorate the gasket
prematurely.
Periodic Maintenance
• The chimney should be swept at least
once a year together with the flue pipe
connection. Care should be taken to
ensure that there is not a build up of
soot on the baffle and in the airways of
the appliance.
• If the appliance has not been operated
for long periods, the flue should be
inspected and swept before use to
ensure there are no blockages within
the flue.
• The internal vermiculite panels of the
appliance should be checked regularly
for soundness. If any wear and tear is
found, we recommend these parts are
replaced immediately.
• Check the rope door seals are intact
and are not worn. These should be
replaced on an annual basis to ensure
the correct operation of this appliance.
• Is advisable as part on the periodic
maintenance of your appliance to
lubricate the moving parts of your
stove i.e. handle, air control, door
hinges with a suitable high
temperature dry lubricant (i.e. micro-
fine graphite powder) this will ensure
the correct operation of your
appliance.
• It may be necessary to adjust to
tension of the door closing mechanism
during the lifetime of the appliance as
the sealing rope will compress over
time, this is achieved by the adjusting
the bracket on the body of the stove
to the required tension.
Summer
• When the stove is not going to be
used for long periods e.g. the summer
months, we recommend that you keep
the air slides fully open and the door
slightly ajar if possible. This will help to
prevent condensation which may in
turn lead to internal corrosion of
component parts.
We recommend that the appliance is serviced
annually by a competent engineer to ensure it’s
continued safe operation.

Refractory internal panels
Woodpecker WP4 Refractory panels:
During the normal operation of your
ACR stove, the refractory panels
will experience heating and cooling.
Sometimes minor hairline cracks
can occur. All ACR stoves have a
steel or cast iron structure behind
the panels and therefore even if the
cracks get larger, the stove will still
operate safely.
It is advisable to replace the internal
panels when:
• The cracks are greater than 3mm.
• The surface of the refractory panel
has eroded more than 25% of it's
original thickness, or
• When the panel starts to crumble
and fall apart in chunks.
To prevent the issue from
happening and prolong the life of
your internal panels, the
homeowner should "burn in" the
refractory panels in the new
appliance by building small kindling
fires to begin with and then
gradually working up to a larger fire.
When adding more fuel to the fire,
caution should be used to prevent
excessive mechanical damage to
the panels.
ACR Heat Products bears no
responsibility for the loss or
damage of any kind to the internal
panels during or after installation or
during the normal operation of the
appliance.
Use only replacement parts
recommended by the
manufacturer.
