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).
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 and 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. Further information
on the requirements of the Clean Air Act can be found at 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.
The Woolly Mammoth 5 mk2, Woolly Mammoth 5 Widescreen mk2 and Woolly Mammoth 8mk 2
have been recommended as suitable for use in smoke control areas when burning wood logs. The
Woolly Mammoth 5 mk2 and Woolly Mammoth 5 Widescreen 5 mk2 must be fitted with a
permanent stop to prevent closure of the secondary air controller beyond 50% open. The Woolly
Mammoth 8 mk2 must be fitted with a permanent stop to prevent closure of the tertiary air
controller beyond 100% open. For full details of how to install the smoke control slide plate see
the dedicated section on page 7. Authorised solid mineral fuels can also be used in smoke control
areas. A list of Authorised fuels can be found at www.smokecontrol.defra.gov.uk/fuels.php.
EcoDesign 2022 and Clear Sky Initiative
In a bid to reduce any potential impact the burning of solid fuels may have on our environment,
the bodies that govern our industry (DEFRA, Stove Industry Alliance and HETAS) have introduced
stricter guidelines concerning reduced particle emissions (PM2.5), lower Carbon Monoxide
emissions and improved efficiency levels through better fuel standards and sustainability, by which
a multitude of appliances manufactured after 1st January 2022 and sold in the UK (and Ireland)
must adhere. These are known as Eco Design 2022 Ready or Clear Skies and your Woolly
Mammoth stove has been tested and approved as exceeding these requirements.

Before Installing Your Woolly Mammoth Stove
Suitable ventilation must be provided for the installation of your Woolly Mammoth stove for safe,
efficient operation and compliance with approved document J of the building regulations. Air
vents must remain open at all times and be free of any obstructions. Extractor fans must not be
present in the same room as a heating appliance. Please refer to the building regulations for
minimum air vent sizes for your stove’s output.
EcoDesign 2022 Ready Woolly Mammoth stoves are Cool Hearth Rated and can be installed on
12mm superimposed or decorative hearths. These must measure a minimum of 840mm x 840mm.
If installed on a constructional hearth in an existing fireplace, this must extend a minimum 150mm
from either side of the stove and a minimum 300mm to the front.
Pre-existing chimneys must be in good condition and lined with a minimum 125mm internal
diameter flexible chimney liner. If a chimney does not exist, a suitable insulated twin wall flue
system must be connected to the appliance again with a minimum 125mm internal diameter. All
flue installations must be undertaken by a registered member of a government approved
competent persons scheme and under building control approval from your local authority. Failure
to do so will void the Mammoth 5 Year warranty PLUS.
Chimney draw must be within specification for this stove to operate. With the chimney warm, this
must be between 1-2mm water gauge. Anything higher requires a draught stabiliser to prevent
over firing.
Upon receipt of your stove, please ensure all insulating fire bricks are in position to the sides and
rear of the fire box and the baffle plates are secured in position as these may have become
misplaced during transit. The outlet collar and blanking plate are supplied with screws for securely
fixing to the top and rear outlets. If you are installing this stove in a Smoke Controlled Zone, you
must install the smoke control slide plate (found in the flue collar box) – for full installation details
of the smoke control slide plate, see the dedicated section on page 7.
Woolly Mammoth Stoves - Issue 7 03/02/21 6
Please check all components of your Woolly Mammoth stove are in good working condition prior
to an initial burn. Your stove has adjustable primary and tertiary air intakes below the door and a
secondary air intake above the door, an externally controlled riddling grate and door mechanism.
Installation Health and Safety 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 – The stove contains no asbestos. If there is a possibility of disturbing 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.
Please refer to BS 8303 Code of Practice for installation of domestic heating and cooking
appliances burning solid mineral fuel.
The chimney must be swept and examined for soundness and suitability before the appliance is
installed. Remedial action should be taken if required, seeking expert advice is necessary. Where
the chimney is believed to have previously served an open fire installation it is possible that the
higher flue gas temperature from a closed appliance may loosen deposits that were previously
firmly adhered, with the consequent risk of flue blockage. It is therefore recommended that the
chimney be swept a second time within a month of regular use after installation.
Ensure all parts are fitted in accordance with the instructions.
On completion of the installation allow a suitable period of time for any fire cement and mortar to
dry out, before lighting the stove. Once the stove is under fire check all seals for soundness and
check that the flue is functioning correctly and that all products of combustion are vented safely
to atmosphere via the chimney terminal.
On completion of the installation and commissioning ensure that the operating instructions for
the stove are left with the customer. Ensure to advise the customer on the correct use of the
appliance and warn them to use only the recommended fuel for the stove.
Advise the user what to do should smoke or fumes be emitted from the stove. The customer
should be warned to use a fireguard to BS 8423:2002 (Replaces BS 6539) in the presence of
Woolly Mammoth Stoves - Issue 7 03/02/21 7
children, aged and/or infirm persons. The installer should check the current issues of British
Standards BS EN 15287-1:2007 design, installation and commissioning of chimneys.
CO Alarm - 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.
Warnings
Properly installed, operated and maintained this stove will not emit fumes into the dwelling.
Occasional fumes from de-ashing and re fuelling 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:
(a) Open doors and windows to ventilate the room and then leave the premises.
(b) Let the fire go out.
(c) Check for flue or chimney blockage and clean if required.
(d) Do not attempt to relight 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 flueway or chimney blockage. For your own safety
these must be kept clean at all times.
Aerosol sprays should not be used near the stove when it is alight.
Please note that parts of the stove become very hot while the stove is running, so should not be
touched with bare hands. A heat proof glove should be used for the operation of the hot stove.
Product End-of-Life/Recycling: To dispose of the stove after the product life has expired, please
observe the following information:
• Dispose of the items correctly i.e. separate the parts to be disposed of in material
groups.
• Always dispose of items in a way that is as sustainable as possible and that is in line with
the current environmental protection, reprocessing/recycling and disposal technology.

Use in Smoke Control Zones (WM5 & WM5 WideScreen)
If installing in a smoke control zone you must install the smoke control slider plate to the
secondary air control prior to use for models WM5 and WM5 WideScreen or engage the Smoke
Control Block on the WM8 model. Failure to install this correctly will result in the stove not
complying with regulations for use in a smoke control zone.
For WM5 and WM5 WideScreen models, you will find your smoke control slider plate in the flue
collar box when unpacking your stove. It is a fairly straight forward process to install this onto the
secondary air slider (located centrally above the stove door). Just follow the steps below:
Step One
Step Two
Locate the smoke control slider plate (packed
in the flue collar box) and unscrew the
secondary air control knob.
Notice that one side of the slider has a
stopper that protrudes and a hole in the
centre for the air control.
Step Three
Step Four
Place the central hole in the slider over the air
control with the protruding stopper facing
inwards and to the left of the air control.
Ensure that the air control is set to the right
to allow room for the stopper to sit in the
channel.
Re-screw the knob onto the control. You
have now installed the smoke control slider
plate and your stove is ready for use in a
smoke control zone.

Use in Smoke Control Zones (WM8)
For the WM8 model the procedure to ensure compliance with DEFRA regulations in a smoke
control zone is different. Underneath the (in between the heat shield and the underside of the
stove body) you will see a lever arm which will be in the open position (as in the image below).
To ensure compliance for use in a smoke control zone the install must first pull the tertiary air level
(the right hand bottom level control) all the way forwards and then close the lever arm under the
stove which when fully closed will prevent movement of the tertiary air lever, as shown below:
Woolly Mammoth Stoves - Issue 7 03/02/21 10
Basic Operation
Your Woolly Mammoth stove comes equipped with 4 Main controls:
Primary Air Control (A) – The main air control, used predominantly during start-up/lighting of
your stove. This works on a push-pull slider system
Tertiary Air Control (B) – Your tertiary air control allows you to control the amount of hot air
fired into the burning chamber to re-ignite the smoke for a more complete burn. This works on a
push pull slider
Secondary Air Control (C) – This works on a left to right slider system and controls the flow of
secondary air into the stove. This air allows the stove burn to be controlled at a lower burn rate, as
well as the air wash that keeps the glass clean.
Riddler Control (D) – This is the control for the riddling grate. This works on a push-pull slider
system
