 The installer has a responsibility to ensure that all requirements of Health & Safety at Work
Act are observed & implemented as stated on the date of installation.
 Due to the weight of this stove adequate facilities must be available for loading, unloading &
installation.
 Always ensure that there is an adequate air supply into the room containing the stove.
 It is very important that flue ways are regularly swept & checked by an approved person. It is
recommended that sweeping and checking should be done at least twice each year for
approved smokeless fuel use and quarterly each year for wood burning. The installer must
ensure that the chimney is examined for soundness and suitability before the appliance is
installed. Remedial action should be taken if required, seeking expert advice if necessary.
Where the chimney is believed to have previously served an open fire installation it is possible
that the higher flue gas temperatures 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.
 All dampers or restrictors must be removed from the flue.
 This stove must be maintained to ensure safe operation & efficiency.

the product.
1.2 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 "authorized" fuels) have been exempted by an Order made and
signed by the Secretary of State or Minister in the devolved administrations.
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."
To ensure smokeless operation opertate the stove in accordance with these instructions.
(Please see instructions within this manual).
The Windermere 5 SE have been recommended as suitable for use in smoke control areas when
burning wood.
The Windermere 5 SE must be fitted with a permanent stop to prevent closure of the secondary
air control beyond 10.5mm open and the tertiary air control beyond 12.5mm open.
The appliance is only exempt when used in accordance with these instructions.
1.3 HETAS Ltd approval
The Windermere 5 SE appliance has been approved by HETAS Ltd as an intermittent operating
appliance for burning wood logs.

Never use or store aerosol sprays or any other combustible products in the vicinity of the stove
when it is in operation or whenever the stove is hot. The stove will remain hot for some time even
after the fire is extinguished.
When lit, a wood-burning stove gets hot and therefore adequate protection must be provided,
particularly in situations where there is a safety risk to children or the infirm. When using this
stove in situations where children, aged and / or infirm persons are present a fireguard

18
manufactured in accordance with BS 8423:2010 + A1: 2016 must be used and such persons must

It is also recommended that all other people should use a fireguard in accordance with BS
8423:2010 + A1: 2016 at all times when the stove is alight or hot.
3.4 The chimney.
Refer to current National laws, Building Regulations, and any Rules in Force, including British
standard BS EN 15287-1:2007 and BS 8303 and (Approved Document J England & Wales)
The construction of the masonry chimneys, flue block chimneys and connecting flue pipe system
must meet the requirements of the Current National laws, Building Regulations, and any Rules in
Force.
This stove must never be connected to any shared chimney.
An efficient modern stove places heavy demands on the chimney, and you should have the
chimney regularly swept and inspected at least twice a year for smokeless fuel use and quarterly
for wood fuel use by an approved chimney sweep.
The flue or chimney system must be in good condition. It must be inspected and swept by a
competent registered person and passed for use with the appliance before installation. The
National Association of Chimney sweeps (NACS) and for Northern Ireland (NIACS) Northern
Ireland Association of Chimney Sweeps offer a register of approved chimney sweeping and
inspection services who will issue certificates after inspection and sweeping.
Where the chimney is believed to have previously served an open fire installation it is possible that
the higher flue gas temperatures 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 by an approved &
competent chimney sweep.
If it is necessary to fit a register plate it must conform to the Current National laws, Building
Regulations, and any Rules in Force.
The minimum height of the flue or chimney must be 4.5m from the hearth to the top of the flue,
with no horizontal sections and a maximum of 4 bends. Bends must have angles of less than 45
degrees from the vertical. There should be at least 600mm of vertical flue pipe above the appliance
before any bends are introduced. Ensure the connecting flue pipe is kept a suitable distance from
any combustible material and does not form part of the supporting structure of the building.
The installer must ensure the flue pipe diameter is not less than the diameter of the outlet of the
appliance and does not narrow to less than the size of the outlet at any point in the system.
Make provision to remove the appliance without the need to dismantle the chimney.
Any existing flue must be confirmed as suitable for the new intended use as defined in the Current
Building Regulations.
The flue or chimney systems must be inspected and swept by an approved chimney sweep to
confirm the system is structurally sound and free from obstructions.
The flue exit from the building must comply with Current National laws, local building control
rules, Building regulations and any Rules in Force.
Chimney heights and / or separations may need to be increased in particular cases where wind
exposure, surrounding tall buildings, high trees or high ground could have adverse effects on flue
draught
It is highly recommended that an approved and certified flexible flue liner that complies with
Current National laws, Building Regulations and any Rules in Force of the correct internal

19
diameter be used to line the chimney, the liner must be approved for use with Multi Fuel burning.
Flue liner installation must comply with Current National laws, Building Regulations, and any
Rules in force, also refer to the flue liner manufacturer’s instructions. The flue liner must be
replaced when an appliance is replaced, unless proven to be recently installed and in good
condition.
The cross-sectional area of the chimney (at its narrowest point) must comply with Current
National and Local Building Regulations and any rules in force. Generally, the area needed for a
wood-burning stove installation should measure at least 150 mm internal diameter. Please refer to
Current National laws, Building Regulations, and any Rules in Force.
Important note: The Windermere 5 SE has been tested for smoke exemption so a minimum
internal flue diameter of 125mm can normally be used. *(This must be confirmed with HETAS or
Local Authority Building Control and all Current National laws, Building regulations and any
Rules in Force).
An over-sized chimney is generally hard to keep warm and results in poor draft. In cases where
there is an oversized masonry chimney, it is highly recommended that the chimney be lined using
an appropriate and approved chimney lining system with the correct internal diameter as stated
above.
With respect to the chimney termination, all chimneys must terminate in accordance with Current
National and Local Building Regulations.
Note: Current National and Local Regulations also apply with regard to the placement of
chimneys and flues in connection with thatched roofs.
The chimney or flue system must be equipped with access doors for inspection and cleaning. The
size of the cleaning door in the chimney must at least equal to that of the cross-sectional area of
the chimney. In the event that a chimney fire occurs resulting from faulty operation or prolonged
use of damp wood fuel, if safely possible close the air vents of the stove completely, evacuate all
persons from the building and contact your local fire department immediately.
3.4.1 Stove Pipe connection.
Refer to: Current National laws, Building Regulations, and any Rules in Force including BS 8303
and BS EN 15287-1:2007 and (Approved Document J England & Wales)
There are two stove flue exits enabling either top or rear venting depending on installation
requirements.
Check that the flue collar adaptor and flue blanking plate rope seals are not damaged and in correct
position. See figures 3.0, 3.1 & 3.2
Top flue exit position.
If using the stove top flue exit, un-screw and remove the 3 flange bolts supplied from the stove top
flue exit position.
Check that the flue collar adaptor rope seal is not damaged and in correct position.
Align the flue collar adaptor to the stove top flue exit position ensuring the 3 flange bolt hole
positions align with the 3 threaded holes to the stove top flue exit position.
Screw each bolt through each flue collar adaptor flange into the threaded holes within the stove
top, evenly tighten the 3 bolts so the flue collar adaptor is securely fastened to the top of the stove.

20
Rear flue exit position.
If using the rear flue exit position, remove the steel heat shield to the rear of stove by un-fastening
the 4 securing nuts, this will expose the rear flue blanking plate.
Un-fasten the 3 bolts securing the blanking plate and remove.
Check the flue blanking plate rope seal is in correct position and un-damaged.
Securely bolt the blanking plate to the stove top flue position as described above.
Securely bolt the flue collar adaptor to the stove rear exit flue position as described above.
Securely fasten the heat shield to the rear of stove using the 4 nuts supplied.
A suitably gauged metal rigid stove flue pipe of the correct size complying with Current National
laws, Building Regulations, and any Rules in Force (not supplied), is connected to the flue collar.
The joint between the stove collar and rigid stove pipe must be fully sealed using suitable stove
rope / fire cement. When the rigid stove flue pipe is fully inserted into the stove flue collar drill
two suitably sized holes in a suitable position 180 apart through the stove flue collar and rigid
stove pipe and use either corrosion proof self-tapping screws or bolts, nut and washers of suitable
size to ensure the rigid stove pipe is unable to be pulled out of the stove collar. Ensure the
self-tapping screw or bolt nut and washers do not obstruct the stove collar flue way and ensure the
screws or bolts and locating holes are airtight.
The chimney or flue way that the stove pipe is connected must be at least 125mm internal
diameter. (ii) rectangular or square flues having the same internal cross-sectional area and a
minimum dimension of 100mm for straight flues or 125mm for flues with bends or offsets. Refer
to Current National laws, Building Regulations, any Rules in Force including BS 8303 and BS EN
15287-1: (This must be confirmed with HETAS or Local Authority Building Control and all
National laws, Building regulations and any Rules in Force).
