The Clean Air Act 1993 and Smoke Control Areas
DEFRA
APPROVED
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
"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).
The Secretary of State for Environment,
Food and Rural Affairs has powers
under the Act to authorise smokeless
fuels or exempt appliances for use in
smoke control areas in England. In
Scotland and Wales this power rests
with Ministers in the devolved
administrations for those countries.
Separate legislation, the Clean Air
(Northern Ireland) Order 1981, applies in
Northern Ireland. Therefore it is a
requirement that fuels burnt or obtained
for use in smoke control areas have
been "authorised" in Regulations and
that appliances used to burn solid fuel
in those areas (other than "authorised"
fuels) have been exempted by an Order
made and signed by the Secretary of
State or Minister in the devolved
administrations.
• The Oakdale
(FB1MF) 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 25mm 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:
http://smokecontrol.defra.gov.uk
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.
Installation Instructions

Oakdale FB1 A5 0414-1 28/04/2014 08:39 Page 4

Operating your stove
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.
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.
The appliance should not be operated in
mild weather with smokeless fuel. Under
certain weather circumstances e.g. fog
the chimney will not draw sufficiently
and could cause asphyxiation. Either
await better weather conditions or burn
wood only.
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
slides have 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.
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
300mm, maximum width 125mm.
Smokeless Fuels: below 20%
Petroleum coke content such as
Anthracite, Phurnacite, Ancit suitable for
use use with a closed heating appliance.
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.
Always check with your dealer or directly with the manufacturer as
using the incorrect fuel may invalidate your guarantee and damage
your appliance.
Assembly of the unit

Operating your stove
Instructions for use with
wood
• Pull the secondary air slider (marked
with a double hole) fully forward and
open the primary air slider (marked
with a single hole) fully by pulling the
lever forward.
• Pull the tertiary air slider (Marked with
no holes located under the body of the
appliance) out by approximately 50%
• Lay firelighters or rolled up
newspapers 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 firelighters
using a long taper and push the door
closed but do not engage the locking
handle fully.
• When the fire is burning fiercely, after a
couple of minutes add more logs and
close the door.
• When the fire has become established,
close the primary air (marked with a
single hole) down by pushing the lever
inwards.
• The burning rate can be altered by
moving the secondary air slider
(marked with a double hole) - 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 not placed higher than
the log guard allows. This stove
features a split log guard to allow
differing loads to be managed, only
alter the log guard when the appliance
is fully cold.
Instructions for use with
smokeless fuel
• Pull the secondary air slider (marked
with a double hole) under the ashlip
and open the primary air slider
(marked with a single hole) fully by
pulling the lever forward.
• Make sure that the tertiary slider
(Marked with no holes located under
the body of the appliance) is fully
pushed in.
• Lay firelighters or rolled up
newspapers on the grate and add a
small amount of kindling wood to the
top. Place a small quantity of
smokeless fuel on top.
• Light the newspaper or firelighters
using a long taper and push the door
closed but do not engage the locking
handle fully.
Operating your stove
• When the fire is burning fiercely, after a
couple of minutes add more
smokeless fuel and close the door.
• When the fire has become established,
close the secondary air (marked with a
double hole) down by pushing the
lever inwards.
• The burning rate can be altered by
moving the primary air slide (marked
with a single hole) - pull forward to
fully open and push inward to close
down.
• Care should be taken to ensure that
the firebox is not overfilled with
smokeless fuel - it should be no
higher than the log guard. This stove
features a split log guard to allow
differing loads to be managed.
Re-fueling
When refueling the stove always refuel
onto a bed of hot embers, fully open
the secondary and primary air controls
until the new fuel is well alight, before
adjusting the air controls 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.
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.
• 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. 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 refueling.
It should not be operated as an open
fire.
Typical refueling intervals for wood is
1 hour and smokeless fuel is 2 hours.
Daily Maintenance
The ashpan should be checked and
emptied regularly.
• You should never allow the ashes in
the pan to build up to the level of
the grate.
If they are allowed to build up, the grate
will become sandwiched between the
ash below it and above it. This will
overheat the grate and cause distortion
and premature wear.

Maintenance
Troubleshooting
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 grate should be cleaned regularly
and the ashpan 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 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.
• 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 difficult 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
fire and once established use split logs
• Not enough primary air Open air control
• Insufficient draft Check the flue 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 flue
Smokes while burning • Insufficient draught Check the flue is not obstructed
Low heat output • Poor quality wood Use seasoned Hardwood (this has a
Higher calorific value)
Problem Probable Cause Action Recommend
Commissioning Check List
