1. Introduction
Thank you for purchasing one of our replace stoves and congratulations on becoming the
owners of a prestigious quality appliance by Docherty.
Our replace stoves can function as additional heating to augment the atmosphere of your
home or recreational building or as the main source of environmentally-friendly heating with
high heat output, clean operation and perfect combustion. All replace heaters produced by
our company are tested in accordance with EN 13240/2002+A2/2005 or EN 13229/2002.
Please read through the manual and technical sheet thoroughly. The user is obliged to get
properly acquainted with proper installation and operation of this device with regards to its
safe operation. Please retain the manual and technical sheet as a reference guide so that you
can brush up all the information necessary for the correct operation of your replace stove
before each heating season.
We only provide a warranty on our products if all the instructions listed in this operation
manual are adhered to.
2. Technical description
Fireplace stoves are intended for installation into various interiors (apartments, recreation
buildings, restaurants). Docherty stoves are manufactured from quality construction
materials – cast metal, CORTEN steel and quality construction and steel ttings, with stressed
parts made of HARDOX steel. The surface of steel constructions is protected by a refractory
opaque paint. Refractory paints are not anti-corrosive.
The combustion chamber is lined with chamotte re bricks, which when in service are not
connected by any paste material to prevent damage by heat dilatation.
The combustion chamber can be rmly closed by doors with special heat-resistant glass. The
glass not only increases the aesthetics of the ickering ames, but also facilitates pleasant
heat radiation. The glass also prevents the sparks from the burning wood and smoke from
entering the room. The oor of the combustion chamber is equipped with a removable cast
iron grate. Usually, a barrier is created in front of the grate to prevent the fuel falling and
sliding onto the doors (front window). Stoves with a grate include an ashpan under the grate.
The stove can be ued top or rear.
The stove has an inner and outer casing, the area between the casings is used for convection
air heating. The upper part of the outer casing includes vents for the heated air. The outer
casing may include ceramics or stone to highlight the design and improve the heat accumulation
properties of the replace stove.
Fireplace stoves equipped with a separate intake of primary and secondary combustion air
include the appropriate control elements. The primary air is taken to the burning fuel (usually
through the ashpan and grate) and is used for primary combustion. The secondary air
supports combustion of residual combustible gases in the exhaust, increasing the output of
the appliance and signicantly reduces the amount of pollutants escaping into the atmosphere.
The secondary air is mostly taken to the area above the burning fuel. Its presence causes the
hot air and gases to roll around the inner side of the front glass. This process simultaneously
prevents the blackening of the front glass.
The secondary air also participates in the primary combustion process when the primary air
intake is partially or completely sealed. Keep the primary air intake fully open at the beginning
of the combustion process, when the chimney draught is still weak.

4
After the chimney heats up, you can partially or even completely close the primary air intake,
based on the target output of the replace stove. It is also possible to reduce the fuelling or
limit the chimney draught by attaching a draught stabiliser. This is recommended especially
for a chimney draft around and above 20Pa. The replace and ashpan covers must always be
closed except for starting operation, adding fuel and removing solid combustion remnants to
prevent exhausts entering the room. Some replace stoves are equipped with a heat
accumulation exchanger, improving the eciency of the replace stoves and maximally
utilizing the fuel energy.
Some replace stoves are manufactured with a central air intake (CAI). This allows air to ow
into the combustion chamber in the replace stove from the exterior OR adjoining room,
halls, technical rooms etc. Fireplace stoves with a CAI are not dependant on the amount of air
in the heated area.
Thus, they not only contribute to a pleasant atmosphere in your home, but also reduce energy
expenses (since heated air already in the room is not consumed).
Fireplace stoves with CAI are very suitable for installation into low-energy houses. It is also
possible to equip the heating system of some replace stoves with CAI with electronic
combustion regulation to increase comfort. This can additionally increase the combustion
process and stoking intervals, increase operation safety and prevent uneconomic heating
and over-heating of replace stoves (the shutter of the central air intake is controlled by a
control unit and servomotor in relation to the current combustion phase and output exhaust
temperature).
In all cases when using the direct air connection the installer is required to install and com-
mission the appliance inline with current Building Regulations, manufacturer’s instructions
and any commissioning guidelines for a direct air kit, (example: the HETAS Direct Air Supply
guidelines TN010, TN011, TN012. Details are also going to be included in the next revised
standard of BS 8303). Details are available on request.
Warning: The replace stoves are not manufactured to provide continual heating and are
intended for periodic interrupted operation, mostly due to the need to empty the ashpan
when the ash has cooled down.
3. Safety regulations
Special care must be taken when installing the stove such that the requirements of the
Health and Safety at Work Act are met.
A supply of sucient amount of combustion air and room ventilation air must be ensured
when the replace stoves are in operation, especially with another heat device running
simultaneously. The regulation grate for combustion, ventilation and heating air must not be
obstructed.
When stoking fuel, always open the door very slowly. You will prevent smoke and ash from
escaping into the room. The replace stoves require casual attendance and inspection.
Flammable fuels must not be used for stoking or heating! In addition, burning plastic material
of any kind, wood materials with various chemical bonding agents (chipboards, etc) or
unsorted domestic waste with remaining plastics is prohibited.
Make sure to prevent children from handling the replace stoves during heating. The stove
may only be operated by an adult person! A reguard to BS 8423:2010 should be tted in the
presence of children, aged and/or inrm persons. During heating all handles and knobs must
be operated using a pair of tongs, hook or by a hand protected by a glove due to the risk of
burns. Objects made from ammable materials that could be set on re must not be stored
on the replace stoves during operation and while hot.

5
Please pay special attention when handling the ashpan and when removing hot ash due
to danger of burns! The hot ash must not get in contact with ammable objects -e.g. when
throwing in communal waste containers.
When the replace stove is used only seasonally and with unfavourable draught or weather
conditions, special attention must be paid when putting the stove into operation. When the
replace stove is not in operation for a longer period of time, the ueways must be checked
for obstructions before further operation.
Handling
Adequate facilities must be available for loading, unloading and site handling. This appliance
is heavy and must be handled with care.
Fire Cement
Some types of re 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
This stove contains no asbestos. If there is a possibility of disturbing any 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.
3.1 Safe distance:
3.1.1 Safe distance of replace stoves from ammable materials
200mm to sides
200mm to rear
800mm in front of the centre point of door assembly
Any storage area built into the appliance must not be used to store any combustible materials.
The installation must comply with current Building Regulations, National and European
Standards, Local Authority byelaws and other specications or regulations as they aect the
installation of the stove. The most stringent clearances to combustibles should be applied.
3.1.2 Safe distance of chimneys from ammable materials and building constructions
Follow Building Regulations and Manufacturers instructions for the type of chimney, the
most stringent clearances should be applied.
3.2 Floor protection
Unless the replace stove is installed on a 100% non-ammable oor with a superimposed
hearth or change in level reference Building Regulations Document J section 2.22 – 2.30, it is
necessary to place the stove on a non-ammable insulation mat, e.g. metal plate, ceramics,
hardened glass, stone (at least 12mm thick) and be capable of supporting the weight of the
appliance. The hearth should extend 150mm to sides and rear of the appliance and 300mm
in front of the appliance.
Items made of ammable materials may not be placed on top of the hearth or at a less-than-
safe distance from the replace stoves.
Minimal distances:

3.3 Chimney re prevention measures:
Ordinary operation, especially with humid fuel, leads to the settling of ash and tar in the
chimney. Neglecting regular checking and cleaning of the chimney in accordance with Building
Regulations increases the danger of re. We recommend that the chimney should be swept
twice a year.
In case of ash or tar catching re in the chimney, please follow this procedure:
• do not under any circumstances extinguish the re with water as it would create an
abnormal amount of steam and subsequently rip the chimney open
• if possible, the combustion chamber should be covered with dry sand, which will extinguish
the re
• close all intakes of air for combustion; if possible, cover the chimney. However, the smoke
must not accumulate back in the house
• contact your nearest re ghting brigade to assess the situation and the necessity to
report it as a re ghting emergency
• do not leave the house until the chimney is burned up; regularly check the chimney
temperature and the course of combustion
• contact a chimney service engineer before starting a new re in the stove to assess the
state of the chimney and also contact the manufacturer of the replace stove for inspection.
4. Installation
The installation must comply with current Building Regulations, National and European
Standards, Local Authority byelaws and other specications or regulations as they aect the
installation of the stove. The Building Regulations requirements may also be met by adopting the
relevant recommendations in the current issues of British Standards BS 8303 and BS EN15287-1
The appliance must be tted by an approved installer or inspected and signed o by a Building
Control ocer.
Note: It is a requirement where a new or replacement xed solid fuel appliance is installed in a
dwelling that a sealed carbon monoxide alarm to standard BS 50291:2001 is tted in the room
where the appliance is tted and xed as described in Building Regulations Document J section
2.34 – 2.36.
4.1 General
The replace stoves must be installed on a oor with an adequate bearing capacity. If the
existing arrangement does not meet this basic requirement, necessary steps must be taken
(e.g. using a hearth for distributing the load). Make sure that there is enough space and
provision for cleaning and servicing the replace stove, connecting ue pipes and the chimney.
4.2 Chimney connection
Before installing the appliance the chimney construction should be checked to conrm that
it will be suitable for the installed replace stove nominal output as far as design, ventilation
requirements and eective height are concerned. A suitable chimney (minimum prole,
chimney draft, tightness, etc.) is a basic condition for the proper functioning of the replace
stoves. Chimney values are included in the attached technical sheet. The connecting ue pipe
should not be smaller than the cross sectional area of the appliance ue gas outlet.
A draught regulator should be installed for chimneys with too strong a ue draught. Such a
draught can cause problems during operation, e.g. intensive burning, high fuel consumption
can also lead to permanent damage of the replace stove. Too weaker draught leads to glass
blackening or to smoke escaping into the room when opening the door and stoking fuel.

7
PLEASE NOTE: SOME APPLIANCES ARE FITTED WITH A SMOKE SHUTTER/DAMPER FITTED
WITHIN THE NECK OF THE APPLIANCE, IF USED TO CONTROL EXCESSIVE FLUE DRAUGHT THE
POSITION TO ACHIEVE THE CORRECT FLUE DRAUGHT SHOULD BE NOTED AND NOT EXCEEDED
WHEN IN NORMAL OPERATION AS THIS WILL RESULT IN PERMANENT DAMAGE TO THE
APPLIANCE.
The minimum eective height of the chimney for exhaust gas from the stove is 5m.
5. Operation manual
5.1 Fuel
It is only allowed to burn wood and wood briquettes in replace stoves. To reach the nominal
parameters of the heater, we recommend using dry logs with a diameter of 5-8 cm and
length of 20-30 cm and with a humidity below 20%. Kindling/chopped pieces of wood should
be used only when starting the re.
Recommended humidity can be obtained by storing the chopped logs for at least two years
in a ventilated shelter. A hand held moisture meter is a way of conrming the moisture
content they are simple and easy to use.
The replace stove should be heated to a nominal output stated in the technical sheet, i.e.
the burning of a given amount of allowed fuel per 1 hour. Long-term excessive output could
damage the replace stove.
Never use ammable uids, coke, coal or any of the following types of waste as fuel:
chipboards, plastics, plastic bags, soaked wood or wood-shavings, saw-dust or pellets!
!!!Burning of the above mentioned material not only highly pollutes our environment but also
damages the replace stove and the chimney!!!
5.2 Starting the replace stove for the rst time
Before the rst use all remaining stickers and transit xings must be removed, all accessories
must be taken out of the ashpan or burning chamber. Check that the bae plates are tted
and located correctly, that the air controls are operating correctly, chamotte re bricks and
grate are set correctly (as they might have slipped from their correct positions during transport
or installation). Correct any defects you might nd, otherwise the proper functioning of the
stove is endangered.
After siting the replace stove and connecting it to the chimney start heating slowly and
continue for at least one hour. Leave the stove and ashpan doors open (approx 1-2mm)
before and during the rst heating in order to prevent the sealing material to mix/stick with
the paint. The replace surface is covered with heat-resistant paint. During the rst heating,
after becoming temporarily soft, the paint will eventually become hardened. During the soft
phase the paint surface is more vulnerable to being damaged by a hand or other object.
During the rst heating the replace stove should be “heated up” with a small ame, burning
only a small amount of fuel with a lower temperature. All materials must get used to the heat
load. You will prevent cracks in the chamotte bricks, damage of the paint or deformation of
the insert materials by a careful rst heating. Hardening of the paint on the replace stove
might be accompanied by a temporary smell, which will disappear after a while.
Make sure the room is properly well ventilated when curing the paint. Furthermore, ensure
that no small animals or birds are present in the room containing paint fumes. We also
recommend turning o aquarium air intakes during the rst heating.

5.3 Kindling and ring
Fireplace stoves with grate - rst put crumpled paper into the chamber and then lay chopped
wood in it.
You can also use an appropriate suitable re-lighter to start the re. After starting re, let
it burn freely with all air regulation elements open. It is forbidden to use ammable liquid
(oil, petroleum, etc.) for starting re! After the re begins to burn and the draught is strong
enough, bigger logs or wood briquettes might be added without the danger of smoke.
Continue stoking the amount of fuel determined based on the nominal output of the stove.
Warning: Fireplace doors must always be closed, with the exception of the rst heating,
stoking fuel and removing ash. When the replace stove is not in operation for a longer
period of time, it is necessary to check that the ue pipes, chimney and combustion chamber
are clear.
In general, the heating up and cooling of the replace appliance is accompanied by a specic
sound; this is normal, it is the expansion and contraction of heated components.
5.4 Stoking fuel
In order to prevent smoke escaping into the room when stoking fuel, please follow the
following procedure: Approximately 5 or 10 seconds before opening the replace doors open
the air intake regulators and then only slightly open the stoking doors, wait for few seconds
for the exhaust gas to get sucked into the chimney and only then fully open the door. When
opening the stoking door, special attention must be paid to the danger of hot re-brands
falling out. After stocking fuel, close the door again. After the fuel starts burning (with clear
re), return the regulator back to its original position. The amount of stoked fuel should
correspond to an hourly consumption value for the concrete replace stove (see the technical
sheet).
Overheating can permanently damage the replace stove construction.
Warning: To prevent exhaust gas escaping into the room during stoking add fuel after its
burning down on the glowing base of the re.
5.5 Operation during the transition period
The chimney draft (sucking exhaust gas from the replace stove) might be weaker during the
transition period, i.e. when the outside temperature is higher than 15°C, during rainy and
humid days or during gust airs.
During this period the replace stove should be operated with the minimum possible fuel so
that the re, as well as the chimney draft could be improved by opening the air intakes.
Tip: During this period a so-called atmospheric plug can be created in the chimney mouth
due to the draft conditions. The plug can cause smoke escaping into the room when lighting
fuel. We recommend letting a piece of paper burn down preferably in the upper part of the
combustion chamber before lighting the kindling. This seemingly negligible smoke is enough
to break through the atmospheric plug. Afterwards you can freely light paper (or an appropriate
suitable re-lighter) and be sure that even a humid chimney is clear.
5.6 Ash removal
Make sure that the ashpan is cleaned when being half full in order to prevent the ash reaching
too close to the grate and thus damaging it. At the same time the ash would block the intake
of air required for burning. Removing ash from the ashpan should be carried out when the
replace stove is cold and preferably ready for the next heating. A vacuum cleaner designed for
cleaning ash with a lter for small lth can be also used for cleaning the cold ashpan.

9
Store the ash in closed non-ammable containers.
Warning: Make sure that the ash does not contain any glowing remains of wood that could
cause re in the waste container.
Be careful when removing hot ash!
5.7 Cleaning the glass
The cleanliness of the window is inuenced not only by the using of suitable fuel, providing
sucient air intake and chimney draft but also by the method of operating the replace
stove. In this respect we recommend stoking only one layer of fuel and distributing the fuel
as evenly as possible and as far from the glass as possible. This also applies for briquettes
(the distance between them should be 5 to 10 mm). If the glass becomes dirty, try increasing
the burning intensity by opening the air intake and the glass will clean itself.
Sooty windows can be cleaned in cold state using newspapers or wet cloth dipped in wood
ash. Usually also liquid cleaning agents are used for cleaning the stove window. But these
may in some cases, depending on the composition of the cleaning agent and its interaction
with combustion residues (ash particles, etc.), harm the gaskets and/or the glass-ceramics
and/or the decoration colour of the replace viewing panel.
The producer is not responsible for damages, which are caused by attack in using of chemical
agents.
6. Cleaning and maintenance
Your replace stove is a high-quality product and no signicant defects will appear during
normal operation. The replace stove and exhaust pipes should be checked thoroughly
before and after the heating season.
Clean the replace stove only after it cools o!
6.1 Cleaning the replace stoves / disassembly of chamotte
All sediments in ue pipes and combustion space must be removed during cleaning.
Remove all fallen-o parts of the chamotte lining. The integrity of the chamotte lining must
be monitored also during the heating season. Spaces between individual chamotte ttings
serve as a heat dilatation preventing cracking of the ttings and must not be lled by lling
material as was usual with older types of solid fuel heaters. Cracked chamotte ttings are still
functional until they fall out! The bae plate should be removed during cleaning (this enables
easier access to the space above them). The replace stove cleaning (with the exception of
glass) should be done without water cleaner, i.e. using only vacuum cleaner or steel brushes.
Any modications of the replace stove are unacceptable.
Use only spare parts approved by the manufacturer. Disassembly of chamotte (see the
Chamotte chamber). From time to time the friction areas of the door hinge and the closing
mechanism should be oiled using carbonic fat or grease designed for high temperatures.
Close the replace stove controls when not in operation.
6.2 Cleaning the chimney
Each user of a solid fuel heater is obliged to ensure regular maintenance and cleaning of
the chimney in accordance with Building Regulations. The frequency may alter with use but
we recommend a minimum of twice a year when burning wood with the correct moisture
content.
