TECHNICAL DATA:

GENERAL INFORMATION:
Before installation of your Pierce Stove these instructions should be read carefully to fully understand the
controls of your new stove. Keep these instructions for future reference.
Due care should be taken when unpacking and installing a Pierce Stove as not to cause damage to your new
stove or its surroundings. Check all components are present and functioning before installation occurs.
INSTALLATION REQUIREMENTS
Installation must always be completed in accordance with current building regulations by a competent
qualified person. Incorrectly installed stoves can cause serious accidents such as chimney fires or
damage to insulation materials in partition walls and or roofs and ceilings. The installation of the stove
to current building regulations is the sole responsibility of the home owner.
CHIMNEY REQUIRMENTS
Do not install a Pierce Stove into a chimney that serves any other heating appliance. The chimney height
must be a minimum of 4.5 meters vertically from the floor on which the stove is installed to the top of the
flue terminal in order for the stove to perform satisfactorily. The chimney should not have an excessive cross
sectional area and should be in good condition without any cracks or blockages. The advice of an expert
should be sought in relation to having the chimney lined, if deemed necessary by an expert a suitable lining
for a solid fuel stove must be used. The internal diameter of any chimney or flue liner used must not be less
than 125mm. Any flue liner and or adaptors used must be fitted strictly to the manufacturer’s installation
instructions. The flue should be checked and swept before connection to the stove. There may be a need to
fit a draught stabilizer if an excessive draft exists, advice should be sought from an expert on the draft
conditions. The chimney should be swept twice per year, any flue liner used should be cleaned in accordance
with manufacturer’s instructions.
AIR SUPPLY VENTILATION
When installing a stove it is recommended that a permanent air vent be fitted if not already in position. The
vent should have an effective area of 550mm2 per kW of rated output above 5kW. In some instillation
conditions under 5kW output stoves will have sufficient air for combustion from natural draughts from doors
and windows. In newer properties designed to be almost airtight it may be necessary to have a vent fitted for
a stove under 5kW rated output. It is recommended to seek expert advice on the air supply/ventilation for
your installation to achieve the best performance from your Pierce Stove. If an air vent is fitted it must not be
obstructed for any reason when the stove is in use. An extractor fan should not be fitted in the same room as
your stove as fumes may emit into the room. It is recommended to fit a Carbon Monoxide alarm for your
safety where you have a stove Installed; this is not mandatory in the republic of Ireland at present but is
mandatory in the UK.
EXTERNAL SURFACE CLEANING
Cleaning on the matt finish stove is recommended with a brush attachment on a vacuum cleaner.
Cleaning on an Enamel finish stove is recommended with mild soapy water and a soft cloth.
Strong abrasive utensils or strong detergents should never be used, always clean the stove after cooling.

DISTANCE TO COMBUSTIBLES
Pierce stoves operate at high temperatures and for safe operation of your Pierce Stove there are minimum
distances to combustible materials, including wood and Plaster board, that must be adhered to at all times.
These distances are as follows (see below diagram also)
100mm to either side of the stove
200mm to the back of the stove
460mm from the flue pipe of the stove
The stove should also be installed on a solid non combustible base.
GLASS CLEANING
When there is sufficient heat generated from the fire the air wash system should keep the glass clean. Over
time the glass may require cleaning, it is recommended to clean with a liquid detergent and soft cloth taking
care not to scratch the glass.
ON COMPLETION OF INSTALLITION
Allow enough time for any fire cement and or mortar used in the installation to dry out according to the
manufactures instructions.
A small fire may then be lit to check the installation of the stove.
Wait at least 24 hours before running the stove at full output.
Please note;
When this stove is properly installed it will not emit any fumes into the room. On occasion
when using the riddling grate or refueling the stove a small amount of fumes might escape
into the room. Constant fume emission is dangerous. If there is persistent fume emission into
the room open the windows and doors and let the fire go out. Check the chimney flue for any
blockages and have them cleaned if necessary. Do not relight the stove until the cause of the
fume emission has been ascertained and corrected, get expert advice if necessary.

CHIMNEY FIRE
It is unlikely you will ever experience a chimney fire if your stove is installed and operated correctly as per the
operation instructions. In the unlikely event of a chimney fire close the primary air and secondary air controls
immediately, evacuate the building and call the Fire Service. Do not re-enter the building until you have
been advised by the Fire service that it is safe to do so. Ensure the stove is not used again until the chimney
has been swept and the stove, chimney and flue have been inspected by a qualified competent person.
IMPORTANT INFORMATION
1. This appliance should not be used as an Incinerator.
2. Non recommended fuels, including liquid fuels should not be used.
3. This appliance, especially surfaces, will be hot to touch when in operation and
due care should be taken. It is recommended to use an appropriate fire guard
when children the aged or infirm are present.
4. No unauthorized modifications should be made to this appliance.
5. Only recommended replacement parts from the manufacturer should be used
for this appliance.
OUTSIDE AIR COMPATABLE
This stove is equipped with an outside air connection on the bottom rear of the stove. The connection can be
connected to a 75mm flexi pipe and connected directly to the outdoors through an underground pipe or
through a wall at the rear of the stove depending on where the stove is positioned in the building. This
allows for the primary air for the stove to be drawn directly from outside instead of from the room. It Is
recommended if used to adhere to the safe distance to combustibles when fitting the pipe and also to fit an
anti vermin cowling to the outside of the pipe.

ELECTRICAL INSTALLATION
The installation of all electrical connections for example the circulation pump, pump thermostat and any
motorized valves must be installed in compliance with local and European building regulations by a
competent qualified person.
PLUMBING INSTALLATION
The plumbing installation must be completed in compliance with all local and European building regulations
by a qualified competent person. When installed the system should not rely completely on a gravity fed
circuit to the domestic hot water tank but should also incorporate a circulation pump for a pumped radiator
circuit. It is recommended to incorporate a heat loss radiator into the gravity fed circuit so in the event of a
power cut or pump failure the hot water generated can dissipate through this radiator along with the
domestic hot water tank. this appliance must be connect to an open vented system without any manual or
automatic valves which could close the flow route from the stove to the systems open vent. Any motorized
valves fitted elsewhere to the system must revert to the open position in the event of power failure to allow
heat to be safely dissipated through the gravity circulation system. See below diagram of a basic heating
system, this diagram is for guidance purposes only.

FAULT FINDING INSTRUCTIONS

OPERATING INSTRUCTIONS:
PRIMARY AIR THERMOSTAT CONTROL
The primary air thermostat control is positioned to the right hand side of the top back of the stove (see
above diagram). When the control is turned fully counter clockwise it is in the fully closed position and when
it is turned fully clockwise it is in the fully open position. The control is numbered from 0 - 4 for you
convenience, 0 being fully closed and 4 fully open. When the stove is in use this control can get hot and it is
advised to use the glove provided with your stove when adjusting. Primary air is normally used more when
burning mineral fuels such as coal.
AIRWASH SECONDARY AIR CONTROL
The airwash/secondary air control is positioned underneath the door to the top front of the stove (see
diagram above). This controls the intake of airwash/secondary air into your stove, slide to the right for the
maximum amount of air and to the left for the minimum amount of air. Over time you will find the best
setting for your installation and type of fuel used. When the stove is in use this control can get hot and it is
advised to use the glove provided with your stove when adjusting. Airwash air is normally used more when
burning wood logs.
RE-FUELLING RIDDLING CONTROL
The riddling control is positioned to the front left side of the stove (see diagram above). Before refueling the
stove riddle the fire by rotating the control back and forward to release all the dead ash to the ashpan
compartment below. When adding more fuel do not over fill the fire box as this can cause damage by over
firing the stove, the fuel should not be filled higher than the front fire fence. After fueling close the door and
adjust the primary air thermostat control to the required setting.
Never let the ash pan become over full as this will cause damage to the grate. Be sure to
empty the ashpan before lighting the stove. Ensure the ash has cooled completely before
removing the ashpan and disposing of the ash.

LIGHTING THE STOVE
First make sure the inside of the stove has been adequately cleaned and that all dead ash has been removed
also ensure the ashpan has been emptied and the ashpan compartment is clear of any dead ash. Open the
primary air to its maximum setting. Place some firelighters or papers on the centre of the grate and light, add
some kindling as required, as the fire establishes itself add your selected fuel and close the door. Adjust the
primary air setting as required.
FUELS
The stove has been tested using smokeless fuel (Ancit) and wood logs. Other fuels are available and may give
similar results. Wood logs up to 43cm long can be used. All fuels should be kept as dry as possible before Use.
