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 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 5WS (WideScreen), WM5 & WM7 have been recommended as suitable for
use in Smoke Control Areas when burning wood logs and with a modified secondary air control to
prevent closure beyond 25% open (WM5WS) or 15% (WM5 & WM7). Authorised solid mineral
fuels can also be used in smoke control areas. A list of Authorised fuels can be found here

Pre-existing chimneys must be in good condition and lined with a minimum 150mm 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 150mm 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.
*Please note 125mm components allowed if stove is DEFRA approved
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.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 6
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 plate is 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 (Woolly Mammoth 5, 5WS and 7 only).
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 secondary air intakes above and beside
the door, an externally controlled riddling grate and door mechanism.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 7
Basic Operation
Your Woolly Mammoth stove comes equipped with 3 Main controls:
Secondary Air Control (A) –This works on a push-pull 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.
Primary Air control (B) –The main air control, used predominantly during start-up/lighting of
your stove. This works on a push-pull slider system
Riddler Control (C) –This is the control for the riddling grate. This works on a push-pull slider
system
Lighting Your Woolly Mammoth Stove
Your new Woolly Mammoth stove is fitted as standard with an adjustable primary air intake
controlled by the slider at the base of the model, an adjustable secondary air intake positioned to
the side at the top of the burner (which also controls the air wash system) and a pre-adjusted
tertiary air intake for complete combustion of all fuels. The air supplied via the primary air intake is
drawn from the front of the stove and the air supplied via the secondary air intake, air wash
system and tertiary air is drawn from the rear of the stove. Air is drawn into the rear of the stove
and heated along the entire depth of the fire box to create an effective air wash system for crystal
clear glass.
1. Check that both the primary and secondary air intakes are in the open position

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 8
2. Build a bed of fuel consisting of crumpled newspaper and a pyramid of kindling
3. Light the newspaper and add larger logs as the kindling starts to burn
4. You may need to leave the stove door open a jar to provide sufficient air at first
5. Once the fire is established, control the burn using the appropriate air intake. Wood
requires an air supply from above for secondary combustion and is controlled by the
secondary air intake whereas coal requires this from below using the primary air intake
6. Allow for a small build-up of ash when burning wood to insulate the fire box sufficiently
or to remove any unwanted ash build up, simply operate the externally controlled
riddling grate.
7. To extinguish the fire, close the primary air intake fully and then the secondary. Do not
completely close all air intakes at once to allow the fuel to efficiently burn out. Once
extinguished, close all air intakes and dampers completely
8. It is advised to light a number of small fires to ‘bed in’ your new stove and ensure the
longevity of the metal construction and any coatings. You must avoid over firing.
Note that the Woolly Mammoth 5WS (WideScreen), WM5 & WM7 have modified secondary air
controls to prevent the complete closure of the air supply. This is implemented to minimise the
potential for smoke emissions.
Spring and Autumn syndrome
Stoves utilise the effect of air current within the flue to both exhaust the products of combustion
and to induce air into the stove. Normally, because the air within the house is warmer than the
outside air the flue is exhausting air from the stove even when it is not operating.
• A hot flue does not “draw” air into a stove, it is the
differences of densities that motivate the lighter gases
upwards.
• The greater the temperature difference between the gases
within the flue and the surrounding air, the greater the
difference in densities and the greater the motivation.
• The taller the flue, the greater the weight of the
equivalent volume of denser air, the greater the motivation.
During the changeable weather conditions of Spring and Autumn the outside temperature can rise
suddenly and become warmer than the temperature within the house.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 9
This causes the air within the flue to reverse its normal flow pattern and air travels down the flue.
The most obvious outcome of this will initially be a smell from the flue and while this is not
harmful it may be unpleasant if the flue has not been swept as often as it should have been.
Because of the warmer outside temperature, the house will feel colder than it is, and the desire to
light the stove and at least match the outside temperature will reveal another problem, the stove
will not light.
If sufficient air is coming down the flue the stove will appear to begin its lighting cycle, but smoke
will emanate from what are normally air inlets and into the room.
The stove may continue to operate in this fashion for a considerable time but because the flue is
operating in reverse there is no possibility of any warm air produced by the stove travelling up the
flue, to warm it, and reverse the flow.
If the house feels colder than the outside temperature, do not light the stove without clarifying
that the air is travelling up, rather than down, the flue.
As mentioned previously, a smell of soot is an indication that the flue is operating in the reverse
but by opening the stove’s door and placing a hand within the stove, it should be possible to
confirm the air flow. Leaving the stove door open for a few minutes may allow enough air through
the flue to warm its fabric sufficiently, to at least stall the air flow, which will make lighting
possible.
If this fails, the practice of directing warm air from a hair dryer into the stove is a solution chosen
by some, who report it to be effective. However, do not attempt this procedure unless the stove is
scrupulously clean and free of all ash, dust and any other debris; the air flow from a hair dryer is
surprisingly powerful.
We would recommend setting the stoves controls to the lighting position, putting two
loosely crumpled pieces of newspaper onto the grate and lighting them. Leaving the main door a
crack open, the thickness of your little finger, and letting the paper burn out. This produces very
little smoke but enough heat to reverse the direction of the flue.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 10
Over Firing
Over firing any stove is dangerous and means the stove is being used beyond its capacity. If the
burner or connections glow red, the appliance is being over fired and will void your warranty.
Under Firing
When fuel is burnt slowly it will produce higher levels of moisture, tar and creosote which will
create condensation and deposits in the chimney. If you are to burn your Woolly Mammoth stove
at a reduced rate, it must be combined with periods of fast burning.
Slow combustion
Should you wish to burn your Woolly Mammoth stove at a slow rate, light the stove in the normal
way to achieve nominal burn. Once optimum flue temperature has been achieved, close the
primary air control and reduce the secondary air control to no more than 25%. This will allow the
fuel to burn slowly whilst still emitting a comfortable heat.
Refuelling onto a low fire bed
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
Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can
cause excess smoke.
Ash Removal
The supplied ash pan must be emptied regularly and never allowed to build up to touch the
underside of the multifuel grate. Some fuels will create more denser deposits than others. Ensure
that you clean the stove on a regular basis.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 11
Fuel Guide
We recommend the use of sustainably sourced British hardwood for Woolly Mammoth
stoves.
Wood fuel naturally has high water content and is not suitable for combustion until seasoned for
approximately two years to achieve a moisture level below 20%. Only then can this be used in your
Woolly Mammoth stove. Wood fuel purchased from an approved source may still require some
drying out to remove surface water before use.
High density hardwood has a slow, steady output producing twice the heat of softwood and is
carbon neutral. For perfect fuel storage, please allow for plenty of air to circulate your wood fuel.
Refuelling Periods and Procedure
The efficient burning of your Woolly Mammoth stove depends on many factors. The type of fuel
you use will define how often you need to refuel the stove. Hard wood will burn longer and
steadier than softer woods, which will burn quickly and produce less heat. We advise the use of
Seasoned Hard Wood in log sizes which do not exceed the maximum log size.
We suggest that you refuel every 45 minutes to 1 hour, dependent on fuel.
Wood fuel with water content greater than 20% (‘green wood’) must not be used for
combustion in a Woolly Mammoth stove. The recommended maximum dimensions of
wood logs are as specified below:
Model
Maximum Length - mm
Maximum Diameter - mm
5
230
175
5WS
375
175
7
475

175
Any moisture must evaporate before the wood fuel will produce heat and during this process the
wet wood will create excessive tar and creosote deposits, damaging both your stove and chimney
system and increasing the risk of a chimney fire.
The Woolly Mammoth 6 and 7XL are wood burning only and the Woolly mammoth 5, 5WS and 7
are suitable for use with wood, coal and solid fuels.
Note that only the Woolly Mammoth 5, 5WS & 7 multifuel stoves have been recommended for
use in Smoke Control Areas when burning wood logs. Woolly Mammoth 5, 5WS and 7 multifuel

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 12
stoves can be used in Smoke Control Areas when burning Authorised solid fuels. A list of
Authorised fuels is available here http://smokecontrol.defra.gov.uk/fuels.php
Please refer to the Solid Fuel Association and Hetas for approved fuel suppliers.
Never burn plastics, household waste or treated timber in your Woolly Mammoth. The use of any
fuel other than that recommended in this user manual will void the Mammoth 5 Year warranty
PLUS
At nominal output, refuelling is required approximately every 1.5hrs. When refuelling, open air
intakes to establish a hot bed of fuel and allow to burn at maximum output for a few minutes
before adjusting air intakes. If there is not a sufficient hot bed of embers when refuelling, smoke
may be emitted from the appliance. Use smaller logs or kindling to reduce this. Do not over load
the fire box. Fuel load should not rise above the insulating fire bricks and/or touch the baffle plate.
Operation with the door open can cause excessive smoke. Operation with the air controls or
appliance dampers open can cause excessive smoke. The appliance must not be operated with air
controls, appliance dampers or door left open except as directed in this user manual.
Maintenance
Your new Woolly Mammoth stove must be regularly maintained.
The grate should be cleaned after use and free of heavy build-up of ashes to prevent this from
burning out, especially with the use of anthracite coals.
The stove, connectors and chimney should be swept regularly, recommended three times a year
by HETAS.
Please check fire bricks regularly. These will crack due to the heat of the stove but this will not
affect operation or heat output. Replacement bricks can be purchased when they crumble or
disintegrate.
Allow the stove to cool before cleaning surfaces with a soft brush or lint free cloth.
Heat resistant coatings are available to renew the finish.
Remove and clean the baffle plate once a month to remove tar and sooty deposits.
Sooty deposits will be removed from the glass through the application of high heat (air wash) and
can also be cleaned when cool with a suitable glass cleaner.
Only replace stove glass with toughened Woolly Mammoth heat resistant glass. Wet logs, pokers
and slamming will damage the glass.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 13
Where a chimney has previously served an open fire, a second sweeping is recommended within a
month of using your Woolly mammoth stove as the higher temperatures may dislodge previously
embedded soot and tar deposits.
When not in use (through the summer months), it is advisable to ensure the stove is clear of all
ash and fuel and air in takes are left open to prevent condensation build up.
Do not modify your Woolly Mammoth stove and ensure chimneys are clear before every heating
season.
Rope seals will require checking and potentially replacing annually. That is why your brand-new
Woolly Mammoth stove has come supplied with 5yrs worth of rope seals. Please use a suitable
heat resistant adhesive.
Check all moveable parts regularly.
Replacement Parts and Accessories
In addition to our market leading 5yr Mammoth warranty PLUS, for complete peace of mind and
to ensure the ongoing enjoyment of your Woolly Mammoth stove, official replacement Woolly
Mammoth stove components are readily available through our approved dealers. Please contact
your local Woolly Mammoth supplier.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 14
Trouble Shooting
The most common assumption amongst stove users is a fault with the stove. This is incredibly
unlikely due to the limited mechanical nature of a wood burner. Stoves are not designed to be air
tight and the effective lighting of a fire, control and draw is dictated by the chimney system which
can easily over or under draw due to many factors.
Fire Won’t Light
Is there sufficient ventilation in the room to supply air to the stove? A permanently open-air brick
must be installed with your Woolly Mammoth stove and extractor fans must not be present. Are
the air intakes open and free from blockages? Is an approved fuel being used in line with the
guide in this user manual? Has the chimney been swept? Does the flue draw fall between the
required levels?
Fuel Burns Quickly
Over firing occurs when too much air is being drawn into the stove due to the chimney system
over drawing. Do the doors close correctly? Are rope seals intact? Are the glass retaining clips
loose? Is the correct fuel being used? It is not unusual to require a draught stabilizer to reduce the
draw on a stove due to excessive flue draught.
Blow Back
If the doors are closed prematurely or intakes are not open enough after refuelling, small
explosions can force air through the seals of the stove.
Smoke Leaks From The Stove
If the chimney system has been installed in line with current building regulations by a registered
installer, this will always provide the required draw to remove all harmful gases and smoke from
the fire box. If smoke is emitted from the stove, please refer to your chimney installer. Is the
system at least 4.5m? Make sure there are no horizontal runs greater than 150mm. Is the chimney
blocked? Are there strong winds pushing the smoke back down the chimney? Is the flue diameter
correctly sized? Are air vents open?
Glass Blackens Quickly
The air wash system fitted as standard in a Woolly Mammoth stove utilises the most effective
system of warming the air along the entire length of the fire box before jetting it down behind the
glass. Increasing the heat and opening the secondary air intake will clear the glass.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 15
The Stove or Door Has Warped
This is due to over firing of the stove beyond its capacity. You must start with small fires over the
course of a few days to ‘bed in’ the stove before taking it to maximum output.
No Heat is Being Emitted
Hot air rises and will be lost up the chimney if this is not suitably capped off with a Chimney
Closure Plate (Register Plate) and sealed with a heat resistant cement or silicone. Is your chimney
over drawing and burning through fuel too quickly? Does your wood fuel have less than 20%
moisture content? Is the baffle plate sited correctly? Open the stove door and listen for wind up
the chimney. If this is the case, install a draught stabiliser or damper to prevent this.
Protection Against Fire Risk
When choosing where to site your Woolly Mammoth stove, it is imperative that you adhere to the
minimum distances to combustible materials as quoted in this manual. During prolonged use of
the stove, the radial area will always be of an elevated temperature to the rest of the room.
Whilst the minimum distances are more than sufficient to fixed items, care should be taken to
ensure that items such as curtains, small soft furnishings such as padded foot stools etc are not
likely to be placed in this area.
Another risk factor to consider is the storage of logs around the stove area. If piled close to the
sides of the stove, heat will build up during the prolonged use of the burner. Over time, this will
cause the core of the logs to heat which could cause them to start smouldering. If this goes
unnoticed, it can lead to ignition of the logs.
If unsure, or in need of advice, please do not hesitate to contact either your installer or Woolly
Mammoth directly.
Chimney Fire Prevention
Causes
The biggest cause of chimney fires is a build-up of deposits such as wood tar or coal soot. As
these build up over time, the risk of chimney fire becomes greater. The deposits will release
combustible volatiles as they heat up from the fire below. Eventually, these may ignite if the
temperature reaches ignition point.

Woolly Mammoth Stoves 2016/GB Issue 5 20/10/17 16
The easiest and most effective way to stop this happening is regular cleaning of the flue/chimney.
This should be done in ratio to the fire usage. We recommend flue sweeping at least once a year.
How To Spot A Chimney Fire
The first sign of a chimney fire is a roaring noise. This is coupled with excess smoke pouring from
the chimney pot. If you see flames coming from the chimney, this will point to the whole flue
being alight.
If you discover a chimney fire, please take the following action:
1. Call the fire brigade –999/112
2. Ensure all air vents and flue dampers are shut to reduce the chimney fire's oxygen
supply
3. Move flammable materials, furniture, ornaments away from the fireplace
4. Feel the chimney breast throughout the house - if it is getting hot then move furniture
away from it
5. Do not pour water on the fire if you have a stove
6. Ensure the Fire Brigade can access the loft space
Ultimately, ensure that you are safe from harm.
