The Clean Air Act 1993 and Smoke Control Areas
SMOKE
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 oence to emit
smoke from a chimney of a building,
from a furnace or from any xed boiler if
located in a designated smoke control
area. It is also an oence to acquire an
"unauthorised 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 Aairs under Section 16 of
the Environmental Better regulation Act
(Northern Ireland) 2016.
In Wales appliances are exempted by
regulations made by Welsh Ministers.
• Wychwood
(WYC1WB) has been
recommended as
suitable for use in
smoke control areas
when burning wood,
as such, when the secondary air
slider is in the closed position it
remains open by 8mm and the
tertiary air control should be fully
open 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 tted
in the same room as the appliance.
The alarm should be installed according
to the alarms manufacturers instructions
and should not be considered a substitute
for the appliance being installed correctly
and regular maintenance of the appliance
and ue system by a competent person.

Installation Instructions
Location of the unit
Clearances to non-
combustible materials
There is a recommended minimum
clearance of 150mm at each side of the
appliance. A clearance of 150mm is
required at the back of stove (if the rear
wall has a thickness of 200mm or more
this measurement can be reduced to
50mm) a recommended clearance of
300mm is required above the appliance
for servicing purposes.
Clearances to combustible
materials
If using an insulated ue with an
integrated appliance connector, such as
the Midtherm HT-S Starter length, the
minimum distance to combustibles is
250mm at the rear and 200mm to the
sides of the appliance. If using a single
walled ue pipe there must be a
minimum clearance of 450mm
clearance at the rear and a 550mm
clearance to the sides of the appliance.
There must be a minimum clearance of
375mm above the appliance to any
combustible materials e.g. wooden
beam.
Curtains and soft furnishings should be
a minimum of 1m away from the
appliance.
Adequate space should be provided for
servicing the appliance.
We do not recommend that televisions
or artwork are positioned above the
appliance.
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.
Hearth Requirements
The appliance must stand on a level
reproof hearth with a minimum
thickness of 12mm. The hearth
temperature created by this stove is
below 100˚C. The hearth must protrude
at least 225mm in front of the appliance
and 150mm either side of the appliance.
The appliance shall be installed on a
oor with an adequate load bearing
capacity. If an existing construction
doesn’t meet with prerequisite, suitable
measures (e.g. load distributing plate)
shall be taken to achieve it.
Flue Requirements
The chimney must comply with current
Building Regulations. Provision must be
made to provide access for cleaning the
appliance, the ue gas connector and
the chimney ue.
The ue must be:
In sound condition and provide
sucient draft (minimum 12pa at start up)
Suitable for use with solid fuel burning
appliances
Be able to clean the entire length of the

Installation Instructions
Location of the unit
To reduce the rear distance to combustible material, the optional manufacturers heat sheild
(Part No - 9900-2370) may be tted to the rear of the appliance. If using an insulted ue with
an intregrated appliance connector, along with the optional rear heat shield, the distances
are:
100mm at the rear of the appliance
250mm at the side of the appliance to combustible materials
Optional Rear Heat Shield
Installation of Heat Sheild
Align the heat shield with the rear of the appliance.
Remove the 3 exsisting bolts from the back of the
unit and ax the heat sheild to the back of the stove
using the 3 M5 x 55 bolts and 20mm spacers
provided.
The spacers must be used to provide a 20mm gap
between the rear of the appliance and the inner face
of the sheild.
Refractory Internal 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 consider replacing 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
 When the panel starts to crumble and fall apart
To prevent the issue from happening and to prolong the life of your internal panels, the
homeowner should “burn in” the refractory panels in the new appliance by building small
kindling res to begin with and then gradually working up to a larger re. When adding more
fuel to the re, 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.

Assembly of the unit
• Remove the upper secondary steel
bae and internal vermiculite bae
(for further instruction please see
under maintenance heading).
• Remove the rear metal cut out plate
from the back of the stove
• Remove the rear blanking plate
• Remove the ue spigot from the top
exit by removing the securing bolts
and rope seal
• Ret the rope seal and ue spigot to
the rear exit and secure with the bolts
• Ret the blanking plate to the top exit
using the rope seal and retaining bolts
This appliance is equipped with a pre-tted manufacturers smoke exempt stop. Under
no circumstances should it be tampered with or removed unless expressly authorised
by a competent person and the appliance is not installed in a smoke exempt area.
If the appliance is to be installed in a non smoke exempt area you can remove the
restricting screw on the secondary air control (on right hand side under the ash lip)
to allow full movement of the secondary air slider.
The appliance is supplied pre-assembled with the ue spigot in the top exit position.
If you intend to install the appliance using a rear ue connection, the blanking plate should be
swapped over as follows:

Operating your stove
Please note that during the rst ring,
we recommend a small re is lit and
that you slowly increase the
temperature to enable the various
parts to expand normally.
You may also experience fumes and a
haze being given o by the stove during
the rst ring and possibly for the next
couple of rings 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 re, the air
slides should be shut down completely
and the fuel allowed to burn out. In the
event of a chimney re, once the air
slides have been closed completely, dial
999 for assistance. If the appliance has
overheated, the appliance and ue will
need to be inspected for any damage
before it can be operated again.
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
350mm, maximum width 150mm.
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% - this will overheat the
appliance and possibly damage
the unit.
Liquid fuels .
Paran re lighter blocks :
these can cause damage to the
glass of your appliance.
Always check with your dealer or directly with the manufacturer as using the
incorrect fuel may invalidate your guarantee and damage
your appliance.
Prohibited Fuels

Recovered wood: i.e pallets, railway
sleepers, painted/treated wood etc.
These will have been chemically
treated and will pollute the atmosphere
and possibly overheat the appliance.
Petroleum Based Coke : over 20% -
this will overheat the appliance and
possibly damage the unit and craze the
glass. Slumbering the stove with this
fuel would also damage the ue liner.

should any solid fuel be used.

Operating your stove
Instructions for use with wood
• Pull the secondary air slider (on the
right) fully forward and open the
start up air slider (in the middle) fully
by pulling the lever forward.
• The tertiary air slider should be pulled
50% open (under the ashlip) at all
times when burning wood.
• Lay relighters or rolled up news-
papers on the grate and add a small
amount of kindling wood to the top.
Place 1 or 2 small logs on the top.
• Light the newspaper or relighters
using a long taper and push the door
closed but do not engage the locking
handle fully.
• When the re is burning ercely, after a
maximum of 5 minutes, add more logs
and close the door.
• When the re has become established,
close the start up air (in the middle)
down by pushing the lever inwards.
• The burning rate can be altered by
moving the secondary air slider (on the
right) - push the lever inwards to close
down and pull outwards to increase
the burn rate.
• Care should be taken to ensure that
the logs are places securely behind
the log guard.
• Secondary - right
• Start up - Boost Air
• Tertiary - left

Re-fueling
When refueling the stove always refuel
onto a bed of hot embers , fully open
the secondary and boost air controls
until the new fuel is well alight, before
adjusting the air controls for the desired
setting.
If there is insucient burning material in
the rebed to light a new fuel charge,
excessive smoke emission can occur.
Refuelling must be carried out onto a
sucient 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 re 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 specied in this
manual should not be exceeded,
overloading can cause excess smoke.
Daily Maintenance
Operating your stove
Operation with door left open
Operation with the door open can cause
excess smoke. The appliance must not
be operated with the appliance door left
open except as directed in the
instructions.
Air controls left open
Operation with the air controls or
appliance dampers open fully can cause
damage to the appliance. The appliance
must not be operated with air controls,
appliance dampers or door left open
except as directed in the instructions.
Operation with the air controls or
appliance dampers open can cause
excess smoke.
• 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 re die. Have the chimney
inspected for blockages and clean if
required. Do not relight the re 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 refueling.
It should not be operated as an open
re.
Typical refueling intervals for wood is
1 hour.
The ashpit should be checked and emptied
regulary.
Never allow the ash to build up to such a
level that it spills out onto the ashlip and
prevents the door from closing correctly.
Never empty the ashpit when the appliance
is alight.
Always dispose of the ashes safely and in a
responsible manner.
Never leave that ash inside the property.

Maintenance
Troubleshooting
The chimney should be swept at least
once a year together with the ue pipe
connection. Care should be taken to
ensure that there is not a build up of
soot on the bae and in the airways of
the appliance.
If the appliance has not been operated
for long periods, the ue should be
inspected and swept before use to
ensure there are no blockages within the
ue.
The Ashpit should be cleaned regularly
to avoid a build up.
• The internal vermiculite panels of the
appliance should be checked regularly
for soundness. If any excess 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.
• The glass can be cleaned using a soft
damp cloth or a ceramic glass cleaner
(available from your local stockist)
Use only replacement parts
recommended by the manufacturer.
We recommend that the appliance is serviced annually by a competent
engineer to ensure it’s continued safe operation.
Fire dicult to • Green wood / wet wood Use hardwood logs with a maximum
start / goes out moisture content of 20%
• Logs are too large Use kindling and small logs to start the
re and once established use split logs
• Not enough primary air Open air control
• Insucient draft Check the ue is not obstructed
Fire burns too quickly • Too much draft Reduce the air control
• Excessive draft Install a draft stabiliser
Smokes on initial • Flue is cold Burn paper and kindling to increase
lighting heat in ue
Smokes while burning • Insucient draught Check the ue is not obstructed
Low heat output • Poor quality wood Use seasoned Hardwood (this has a
Higher caloric value)
Problem Probable Cause Action Recommend

Commissioning Check List
