The Clean Air Act 1993 and Smoke Control Areas
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 Dean Stoves, Dartmoor W5 SE has been recommended as suitable for use in smoke control
areas when burning wood logs.
When using the Dartmoor W5 SE in a smoke control areas the Smoke control kit must be fitted to the
stove.
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
Safety Note
Warning- The external parts of the appliance will get very hot to the touch and due care will be needed
when operating.
All stoves before being operated must be checked that the installation complies with all local, national
and European standards.

2
Before the stove is first used or when fitting other appliances into the room, please check that adequate
air vents are in place to cover the requirements of such appliances.
Extractor fans. When operating an extractor fan in the same room or space as the appliance the
extractor fan could cause the stove not to function properly and pull dangerous fumes into the room.
This must be checked by a trained qualified engineer before using the stove.
Wood & Suitable fuels
Dry wood, 18% moisture content or below must be used or the stove and flue will tar up and the
door won’t stay clean.
Wood is best seasoned by splitting it into a log and drying it out for 2 years in a covered area so the air
can pass through to dry it out. Peat can also be used but must be dry.
When used as a Multi Fuel use only smokeless fuels recommended for enclosed appliances.
Please Note: Appliances should not be used as general incinerators or with non-recommended fuels.
At no time should liquid accelerants I.e.: Paraffin, Petrol, BBQ lighting liquid Etc be used.
Door Operation & controls
The door handle can become very hot so use the glove provided. A tool is provided to control the spin
wheel and air wash lever.
Controlling the stove
Primary air controls –A spin wheel on the door
The primary air control is a spin wheel on the door
This control is used for lighting the fire or boosting
the fire
This is the main control when burning Solid Fuel.
Secondary air- B control leaver is situated on the
right hand side near the top of the stove.
This lever controls the air wash and is used as the
main air control, when burning wood, once the fire is
established
Control lever B works as follows:-
For maximum air flow into the stove push the lever down to open and up to close.
The stove is at its maximum efficiency when the lever is approximately two thirds the way down.
Maximum Log Length
Maximum Log Diameter
400mm
100mm

3
Dampers Left Open
Operation with the air controls or appliance dampers open can cause excess smoke. The appliance
must not be operated with the air controls, appliance dampers or door left open except as directed in
the instructions.
Lighting the Stove with Wood
Lay a fire of sticks and paper. Firelighters can be used if necessary. Check the secondary air lever is
fully open and the primary air spin wheel is partially open. Light the fire and as the fire catches the
paper you may then fully open the primary air.
When the fire has fully established and the logs are burning well shut the primary air spin wheel in the
door and control the fire with the secondary air wash lever (if you are unable to sustain the fire with
secondary control it is very likely that your logs have a high moisture content).
When refuelling the fire, to ensure clean burning, the primary air control should be opened for a
couple of minutes so that flames are established on the newly fuelled logs. The primary air should be
closed once these flames are fully established and the logs have become blackened.
After refuelling, it is recommended that you do not leave the appliance unattended until it is certain
that the logs are burning well with a sustained flame.
The appliance works best by refuelling with two medium sized logs. Typically, the logs should burn
well for about 1 hour.
Please Note: For long periods of burning you will need to use seasoned hard wood. Longer periods of
burning may cause the door glass to blacken, but this can be cleared when you get the fire back up to
temperature and providing the secondary air control is kept slightly open the glass should then stay
clear.
When loading the fire be careful not to leave logs projecting over the log retainer as you may crack the
glass when closing the door.
When the stove is use in the winter season we suggest 25mm (1”) of ash is left in the bottom when
cleaning, as a wood fire burns more efficiently on a bed of ash.
De-ashing the stove is achieved by removing the log retainer and shovelling the ash out into a non-
flammable container, or we suggest using an ash clean attachment which can be plugged into your
vacuum cleaner.
Please note:
If there is insufficient burning material in the fire bed 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
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause
excess smoke.

4
Lighting the stove with Solid Fuel and Multi-fuel kit fitted
Lay a fire of sticks and paper, establish fire and then add the appropriate smokeless fuel, use the
primary air control as the main control. When using a mixture of wood and coal balance the primary
and secondary control to achieve the desired flame picture.
When using solid fuel in this stove you must only use fuels recommended for enclosed appliances, Oil
derivative fuels must not be used as this will shorten the life of the grate.
The Ash pan will need emptying once a day.
When burning solid fuel the stove will work at its best using the primary air control only (door Spin
wheel), it is unlikely you will need to use the secondary air control which will only need to be opened
slightly to keep the glass clear.
In the summer or when the stove is not being used for a long period of time, clear all the ash out and
leave primary and secondary air vents open to prevent condensation.
Please Note:
On lighting the stove for the first time from new the paint on the stove will cure and give off a metallic
smell. It is advisable to ventilate the room i.e. open the windows. This will subside fairly quickly
after the stove has been burning hot for at least 2 hours.
The appliances have been assessed and are suitable for intermittent burning.
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.
Pre-Season Check:
The chimney needs to be swept at least once a year.
The chimney must be checked at this stage for blockages before lighting i.e.: bird’s nests
This is probably the time to have the chimney swept before the beginning of the seasons.
Before lighting at the beginning of the season or after prolonged shutdown periods, check the door
seals are in good condition; the steel insulating plates are in good condition and baffle plate is in
position.
If the stove has been used for a long period of time we suggest the chimney be swept twice a year.
Air vents
Check periodically that the exterior ventilation grill is clear.
Servicing
All servicing must to be carried out by a qualified competent engineer on a regular basis.
No unauthorised modifications of the appliance should be carried out.
Use only replacement parts recommended by the manufacturer.
Notes
Down draughts
In adverse weather conditions a down draught may occur and will make the stove smoke, if this should
happen shut all the stove air controls.
If this occurs on a regular basis call in your engineer.
It is possible a chimney cowl could cure this problem.

5
Refuelling
When refuelling the fire, to ensure clean burning, the primary air control should be opened for a
couple of minutes so that flames are established on the newly fuelled logs. The primary air should
then be closed and the secondary air adjusted to create the desired flame pattern once these flames are
established and the logs have become blackened.
After refuelling, it is recommended that you do not leave the appliance unattended until it is certain
that the logs are burning well with a sustained flame.
Do not load the fuel above the log retainer.
Faultfinding
If the stove starts emitting fumes into the room:-
(1) Check there is no blockage or restriction in the flue.
(2) Check the external air vent is not blocked.
(3) Check the baffle plate has not dislodged itself from the stove.
(4) Call an engineer.
If the stove does not perform properly this could be due to unseasoned wood or too much ash in the
firebox.
In the case of the stove malfunctioning shut all vents, open the windows and let the residual fuel in
stove burn out.
In the event of a chimney fire
•Call the fire brigade
•Raise the alarm to let others in the house know
•Close down all the air controls of the stove, but be careful they could be very hot
•Move furniture, rugs and other objects away from the stove
•Check the chimney breast in other rooms for signs of excessive heat and move objects away if
necessary
•At all times consider the safety of yourself and others in taking the above action
Fitting Instructions for The Dean Forge Dartmoor W5
Stove
These fitting and operating instructions cover the Dartmoor W5 Stove.
Introduction
The Dean Forge range of stoves has been continuously updated for the last 37 years. These stoves
have a robust fully welded carcass with a cast iron door. This stove has sacrificial insulated steel
plates, incorporating an air wash system with 3 outlet options- Top, Rear or Vertical Back box outlets
of 125mm (5”).
Unpacking Stove
Check all the fire bricks and baffle plate are in place and have not moved or been damaged in transit.
Inside the stove packed with these instructions will be gauntlet and a universal air vent- ash pan tool.

6
Before lighting the stove you must check that the installation has been carried out as per instructions
and complies with current building regulations.
Health and Safety Precautions
All work must be carried out to the required Health and Safety at Work Act 1974.
There must not be an extractor fan fitted in the room.
There must be an air vent for all stoves of 5 kilowatt and over or meet current building regulations.
Stoves must be fitted to BS8303, BS6461 PT1-2 1984 building regulations.
All local regulations, including those referring to national and European standards need to be complied
with when installing the appliance.
Flue Connections and Outlets
Dartmoor W5 stoves have the option of taking the flue from the top or the back or using a vertical
back box. Horizontal flue from back of stove should not exceed 150mm.
All flue connections must be sealed with fire cement. Doors in the register plate must be present or a
soot box fitted in the back or side of the fireplace to enable access to clean the chimney when the stove
is installed without a liner.
If the chimney has been lined and cannot be swept through the stove an access door on the first length
of flue must be installed for cleaning access.
The Dartmoor W5 model requires a 125mm (5”) first length of flue then stepping up into a minimum
of 150mm (6”) liner. When using this stove with the smoke exempt air stop fitted the flue liner can be
reduced to 125mm (5”). We strongly advise a minimum diameter of 150mm (6”) flue liner be fitted
when possible. The installation of a flue liner is recommended.
N.B
All stoves must but installed by a suitably qualified person, such as a HETAS engineer or with the
supervision of building control.
As with all stoves fireguards must be installed when young children are present.
