IMPORTANT OPERATION / MAINTENANCE NOTES
Now that your Stanley Solid Fuel Stove is installed and no doubt you are looking forward to many comforts
it will provide, we would like to give you some tips on how to get the best results from your stove.
1. We would like if you could take some time to read the operating instructions/hints, which we are
confident, will be of great benefit to you.
2. Do not burn fuel with a high moisture content, such as a damp peat or unseasoned timber. This will
only result in a build up of tar in the stove and in the chimney.
3. IMPORTANT: The first few fires should be relatively small to permit the refractory to set proper
ly and season the stove. During these firings it is recommended to ventilate the room as an
unpleasant (not toxic) odour may be emitted as the paint is completing curement.
4. Inspect the flue-ways of the stove weekly and ensure that there are no blockages. Check flue
ways before lighting especially after a shut down period. Please see chimney cleaning sec
tion.
5. Before loading fresh fuel into the firebox, riddle fully to remove all ashes. This will allow better and
cleaner burning. See Re-Fuelling section.
6. Never allow a build up of ashes in the ash pan, as this will cause the grate to burn out prematurely.
Empty the ashpan when refuelling.
7. Avoid slow burning of damp or unseasoned fuel as this will result in tarring flue ways and chimney
i.e. peat or timber.
8. Allow adequate air ventilation to ensure plenty of air for combustion.
9. Do not burn rubbish/household plastic.
10. Clean the chimney at least twice a year.
11. Burning soft fuels such as timber and peat will stain the glass. Regular cleaning will prevent
permanent staining. Clean with soapy water when cool.
12. Keep all combustible materials a safe distance away from unit, please see section for clearances
to combustibles.
13. Never use aerosol spray near the appliance when it is in operation.
14. For safety reasons never leave children or the elderly unaccompanied while stove is in use. Use a
fire guard.
15. Avoid contact with the appliance when in use as stove reaches very high operating temperatures.
16. This appliance should be regularly maintained by a competent service engineer.

INSTALLATION & OPERATING INSTRUCTIONS
GENERAL
When installing, operating and maintaining your Ard-
more Stove respect basic standards of fire safety.
Read these instructions carefully before commencing
the installation. Failure to do so may result in dam-
age to persons and property. Consult your local Mu-
nicipal office and your insurance representative to
determine what regulations are in force. Save these
instructions for future reference.
Please note that it is a legal requirement under Eng-
land & Wales Building Regulations that the installa-
tion of the stove is either carried out under Local
Authority Building Control approval or is installed by
a Competent Person registered with a Government
approved Competent Persons Scheme. HETAS Ltd
operate such a scheme and a listing of their Regis-
tered Competent Persons can be found on their web-
site at www.hetas.co.uk.
Special care must be taken when installing the stove
such that the requirements of the Health & Safety at
Work Act are met.
Handling
Adequate facilities must be available for loading, un-
loading 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 with the skin wash immediately with plenty
of water.
Asbestos
This stove contains no asbestos. If there is a possi-
bility of disturbing any asbestos in the course of in-
stallation 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.
“IMPORTANT WARNING”
This stove must not be installed into a chimney that
serves any other heating appliance.
The complete installation must be done in accor-
dance with current Standards and Local Codes. It
should be noted that the requirements and these
publications may be superseded during the life of this
manual.
Please refer to the current standards, BS EN 15287-
1:2007 Design, Installation and Commissioning of
chimneys. BS EN 14336:2004: Heating Systems in
Buildings. Installation & Commissioning of Water
Based Heating Systems. BS EN 12828: 2003; Heat-
ing Systems in Buildings. Design of Water Based
Heating Systems. BS EN 12831: 2003; Heating Sys-
tems in Buildings. method for
calculation of the design heat load.
Your Ardmore stove is supplied with the following
items:
• Ashpan
• Operating Tool
• Touch-Up Paint (Enamel Only)
• Glove
• Flue Spigot
• Thermostat Knob
ELECTRICAL CONNECTIONS
The installation of any electrical services during the
installation of this stove must be carried out by a
registered competent electrician and in accordance
with the requirements of the latest issue of BS 7671.
FLUES
Flues should be vertical wherever possible and
where a bend is necessary, it should not make an
angle of more than 45owith the vertical. Horizontal
flue runs should be avoided except in the case of a
back outlet from the appliance, when the length of the
horizontal section should not exceed 150mm.
CHIMNEY
Do not connect to a chimney serving another ap-
pliance.
The stove is a radiant room heater and must be con-
nected to a chimney of the proper size and type.
The chimney must have a cross-sectional area of at
least 30 square inches 19350sq. mm or a diameter
of at least 6” (150mm). The stove is supplied with a
5” flue spigot, the flue installation will require a 5” to
6” increaser which must be fitted within 1 metre of
flue outlet. It is best to connect to a chimney of the
same size, as connection to a larger size may result
in a somewhat less draught.
A flue that has proved to be unsatisfactory, particu-
larly with regard to down draught should not be used
for venting this appliance until it has been examined
and any faults corrected. An existing masonry chim-
ney should be inspected and if necessary repaired
by a competent mason or relined using an approved
lining system.
6

The stove must be connected to a chimney with a
minimum continuous draught of 0.06 w.g. Poor
draught conditions will result in poor performance.
All register plates, restricter plates, damper etc.,
which could obstruct the flue at a future date should
be removed before connecting this appliance.
If connecting to an existing chimney with a flue diam-
eter of more that 8” it is recommend to line the flue
using a suitable stainless steel flue liner.
Where a masonry chimney is not available a propri-
etary type of 6”/150mm - twin wall, fully insulated pipe
may be used. The pipe must terminate at a point not
lower than the main ridge of adjacent outside obstruc-
tions. With such installation, access to the chimney
must be provided for cleaning purposes.
A chimney / flue termination must be located to min-
imise wind effects, a basic guide is that the distance
from the termination to the roof should be at be at
least 2300mm when measured horizontally and at
least 1000mm when measured vertically, (see Fig.1).
In circumstances where there are adjoining buildings/
structures/ roof openings there are additional require-
ments, please refer to building regulations part J.

FLUE EXIT (TOP & REAR)
The stove is designed to allow the chimney be
cleaned through the stove. If the chimney cannot be
cleaned through the stove it is necessary to provide
a soot box/access door in the flue for cleaning. See
Fig.2 for recommended locations. Fit it to the stove
as shown in Fig.2.
The stove is supplied with a hob blanking plate and
a flue blanking plate. The flue blanking plate can be
altered for use with both top outlet and rear outlet.
The hob blanking plate is for use when the stove is
fitted on rear outlet only. Make sure the flue blanking
plate is sealed correctly. See Figs 3 & 4

DOWN DRAUGHTS
However well designed constructed and positioned,
the satisfactory performance of the flue can be ad-
versely affected by down draught caused by nearby
hills, adjacent tall buildings or trees. These can de-
flect wind to blow directly down the flue or create a
zone of low pressure over the terminal.
A suitable terminal or cowl will usually effectively
combat direct down blow but no cowl is likely to pre-
vent down draught due to a low pressure zone. (See
Fig.5)
VENTILATION & COMBUSTION AIR REQUIRE-
MENTS
It is imperative that there is sufficient air supply to the
stove in order to support correct combustion. The air
supply to this appliance must comply with current
Building Regulations Part J, Heat Providing Appli-
ances. If another appliance is fitted in an adjacent
room it will be necessary to calculate an additional
air supply.
The minimum effective air requirement for this appli-
ance is 71.5cm². When calculating combustion air re-
quirements for this appliance use the following
equation:
550mm² per each kw of rated output above 5kw
should be provided, where a flue draught stabiliser is
used the total free area shall be increased by 300mm²
for each kw of rated output.
NOTE:
There must not be an extractor fan fitted in the
same room as the stove as this can cause the
stove to emit smoke and fumes into the room.
All materials used in the manufacture of air vents
should be such that the vent is dimensionally stable,
corrosion resistant, and no provision for closure.
The effective free area of any vent should be ascer-
tained before installation. The effect of any grills
should be allowed for when determining the effective
free area of any vent.
Air vents should be positioned so that they are not li-
able to blockage.
Air vents direct to the outside of the building should
be located so that any air current produced will not
pass through normally occupied areas of the room.
An air vent outside the building should not be located
less than the dimensions specified within the Building
Regulations and B.S. 8303: Part 1 from any part of
any flue terminal. These air vents must also be satis-
factorily fire proofed as per Building Regulations and
B.S. 8303: Part 1.
Air vents in internal walls should not communicate
with bedrooms, bedsits, toilets, bathrooms or rooms
containing a shower. Air vents traversing cavity walls
should include a continuous duct across the cavity.
The duct should be installed in such a manner as not
to impair the weather resistance of the cavity.
Joints between air vents and outside walls should be
sealed to prevent the ingress of moisture. Existing air
vents should be of the correct size and unobstructed
for the appliance in use.

If there is an extraction fan fitted in adjacent rooms
where this appliance is fitted, additional air vents may
be required to alleviate the possibility of spillage of
products of combustion from the appliance/flue while
the fan is in operation. Refer to B.S. 8303 Part 1.
Where such an installation exists, a test for spillage
should be made with the fan or fans and other appli-
ances using air in operation at full rate, (i.e.extraction
fans, tumble dryers) with all external doors and win-
dows closed.
If spillage occurs following the above operation, an
additional air vent of sufficient size to prevent this oc-
currence should be installed.
Especially Airtight Properties:-
If the stove is being fitted in a property where the de-
sign air permeability is less than 5m3/ (h.m2) (nor-
mally newer properties built from 2006), then a
permanent ventilation must be fitted to provide
550mm2of ventilation for each kW of rated output. If
a draught stabiliser is also fitted then the requirement
is 850mm2per kW of rated output.
EXTERNAL DUCTED AIR
An outside air kit complete with primary air supply
can be ducted from outside and is available to order
for connection to the stove.
It is recommended to bring the air supply for the stove
into the house using a 4” plastic pipe. Where the pipe
meets the outside wall make sure a vent cover is fit-
ted properly to ensure no rodents can enter via the
vent pipe.
The vent pipe should be located to prevent the
ingress of moisture and in a location where it will not
get blocked with leaves or any other debris. As wind
