INTRODUCTION & SAFETY
F2 Fires Limited and Paul Agnew Designs have created this stove to exceed our customers’ expectations.
Functionality, design and high quality are the main priorities for our entire range of superior appliances and
related products. It is our extensive experience and knowledge that ensures your home will be warm and cosy
for many years to come. Sitting in the light and warmth of the fire, you will understand that we simply Create
Atmosphere.
This manual is for the 5kw Ellipse Stove , which is designed to be used as a Freestanding stove. Throughout this
manual we will refer to this model as the ‘appliance’. To further appreciate your new appliance, please read the
following carefully:
This appliance is designed for intermittent use and is tested and manufactured as a closed stove for burning
wood to EN13240 A2:2004. F2 Fires recommends that this appliance is installed by a HETAS registered
installation engineer or a competent person only and failure to comply will invalidate your warranty.
SAFETY - INSTALLATION
Installation of your appliance must comply with all local building regulations, including those referring to UK
National and European Standards. We advise prior to any installation that a full site survey is conducted by a
qualified installation engineer, recognised within an industry standard such as NACS or HETAS to check the
suitability of your chimney and appliance beforehand.
Within the UK, Document J of the Building Regulations contains further information regarding the installation of
solid fuel appliances. This can be viewed by searching for ‘Planning Approved Document J’ online at www.gov.uk
within the United Kingdom. You should also check the relevant planning and building regulations in your own
country and local areas as they may differ from UK National regulations.
SAFETY - VENTILATION
In order for smoke to be drawn up the chimney, the correct amount of ventilation is required. A chimney requires
air movement to work correctly, which is not possible if there is an inadequate source of air. Prior to installation,
you should ensure that your appliance has the correct conditions in order to operate as intended.
This appliance requires fixed ventilation supplying a minimum of 550mm2 of free air.
Other heating appliances that also require air for combustion should not be used in the same room as this
appliance, unless adequate additional ventilation is provided.
For combustion and the evacuation of dangerous flue gases,this appliance requires a supply of air. Without
adequate air supply, the appliance will not operate correctly and smoke may escape back out into your house.
Any air inlet grilles should be positioned so that they are not liable to becoming blocked. Ongoing maintenance
of the air inlet systems is essential to ensure the continued safe operation of this appliance.
An air extraction device should not be used in the same room as this appliance, unless adequate additional
ventilation is provided. Extractor fans when operating in the same room or space as the appliance may cause
problems with the extraction of dangerous flue gases.

capacity
of
your
floor
up to
100 KG
Before installing the appliance, you must ensure that the
load bearing capacity of the floor is equal to the weight of
the appliance, as well as any flue pipes and connections.
The
weight of the appliance is 80Kg approximately when empty.
Remember to also account for the additional weight once the
appliance
contains the internal components and fuel.

CONSIDERATIONS
Test the chimney thoroughly
We recommend that a smoke test is carried out to check for gas tightness within your flue and chimney drafts.
Lining and insulating your chimney before installation is highly recommended. Ensure there is adequate access
to the chimney to allow for sweeping on a regular basis.
Consider additional ventilation
We strongly recommend that you consider ventilation requirements before installation of your appliance. If your
appliance smokes or does not burn very keenly, but improves noticeably when you open a window, this is a
sign that you need to install additional ventilation. See ‘Ventilation’ in Introduction and Safety section for more
information (Page 2).
Suitability
Make sure that the area in which the appliance is to be fitted is suitable for this appliance. Walls adjacent to
the appliance should be of a suitable non-combustible construction material, preferably brick as this appliance
can reach external temperatures of up to and above 300°C. Check adequate precautions are taken to prevent
touching hot appliances. Always use adequate heat proof protection, such as the supplied glove when operating
the metal handle as it will become hot during use and for some time afterwards.
Air Damper
It is recommended that chimneys with a strong updraft be fitted with a flue damper or draught stabiliser to
allow the chimney draught to regulate properly. No damper should close the flueway completely - no less than
20% of the total chimney or flue pipe should remain open at all times.
INSTALLATION & TESTING
Adjustment points on the appliance
The door handle has a sophisticated adjustment system, however,
it comprises of only 4 parts and can be adjusted very simply from
the outside. Over time, the door rope will flatten and the seal will
start to let air into the appliance. This allows unwanted air into the
combustion box and increases the speed of the burn. This will affect
the controllability of the appliance and at this point you should
adjust the handle.
Insert the supplied Allen key into the hole in the side of door
containing the set-screw. Turn it anti-clockwise to slacken the
set-screw until the door handle becomes loose. Once loose, turn
the handle the correct way as shown in the drawing. On
completion, slowly re-tighten the set-screw until the handle is
set and the door shuts tightly again.

Adjustment points on the appliance
This is a free standing appliance and as such once the flue is in
position the appliance should be secure. However, if the floor
surface is uneven, additional fixings are supplied to allow the
adjustment of the four feet. Always ensure the appliance is level
and secure after adjustments are made.
Flue connections
This appliance has a top and rear outlet. The top outlet is the
most common for flue connections. The rear outlet has the same
connections but the blanking plate will need to be removed first
before it can be used. The minimum flue draught required for
nominal heat output is 12 Pascal’s.
At nominal heat output, the flue gas temperature will be in the
region of 242°C. The appliance should never be connected to a
shared flue. Seal the flue connections with fire cement or a high
temperature rope seal. The flue blanking plate should be positioned
over whichever outlet is not being used.
A register plate can be used to seal off the throat of the fireplace
and has a hole for a flue pipe. It also provides access for sweeping
and, if required, has a connection for a bracket to support the flue. A
5” (128mm) flue pipe is required from the appliance to the register
plate.
Testing points
This appliance has a flue test point which has various functions:
●
Helping to ensure correct installation and aiding the installer
to set up the Ellipse with the flue-pull in order to match the
manufacturer’s recommendations. See Flue Requirements.
●
For measuring the flue-pull during servicing to check for soot
or tar buildup in the chimney.
The test point is situated discreetly at the rear right hand side of
the appliance. The M8 screw can be removed and a flue test meter
can be placed in the hole in order to measure the flue-pull. On
completion, always ensure the M8 screw is re-fitted.

OPERATION
Before lighting the appliance
Before lighting the appliance for the first time, please ensure all
firebrick linings and other internal components are in position and
that all packaging has been removed.
When lighting your appliance for the first time, it should not be
stoked excessively as the materials must be given time to adapt to
the effects of heat. Your appliance has been painted with specialist
HT paint and oven cured during the manufacturing process.
However, upon initial lighting of the appliance, further curing may
occur and a slight smell may be evident. We recommend that
windows and doors are left open during this time, which will allow
the smell to dissipate.
Step 1 Place rolled up crumpled newspaper at the back of the
appliance. Next, place a small amount of tinder/kindling on top of
the newspaper followed by a few larger pieces of wood. Light the
newspaper and close the door. NEVER USE FLAMMABLE LIQUIDS
Step 2 Open the front air control fully using the glove provided.
Step 3 Allow the fire to burn until all the pieces of wood are alight and
burning. The side air intake can be used if additional air is needed.
Larger pieces of wood can now be added. Be careful not to add so
much wood that it is in danger of overflowing the fuel bar.
Step 4 Once the fire is established, the air controls can be reduced in
order to maintain a steady burn rate.
REMEMBER:
You should never run the appliance with the door open.

Lighting
HOT SURFACES DURING OPERATION
All parts of the appliance will become hot during use. Always use the glove
provided to operate any element on the appliance, especially the air control and
the door handle. Once lit, ensure that adequate precautions are taken to ensure
that others, including children, pets and combustibles cannot come into contact
with any of the appliances hot surfaces.

STEP

STEP 2
STEP 3
STEP 4

First stage
The fire is usually smokiest just after lighting due to the coldness of the wood and appliance, which can take heat
away from the flames. During this stage, ensure that the air inlet is fully open to increase the flame
temperature and initial heat. Heat will escape straight into the flue system, however, this is a necessary part of
starting an efficient fire.
Initial heat
The additional heat at the first stage will prime the chimney, producing a strong draft. It will also help to keep
the chimney or flue clean by loosening anything deposited during a previous fire. The hot initial burn also drives
moisture from the firewood and gives an ignition source for the smoke that is released from the wood.
Adding fuel
When adding fuel, only make small, gradual changes. Do not add too much fuel at once. Adding fuel gradually
will help to maintain a steady optimum temperature and burning rate so that the appliance burns efficiently
and cleanly.
Adding too much fuel will also dramatically reduce the temperature inside the firebox. After adding large
pieces of fuel, it is recommended that you increase the air opening slightly, so that the new fuel begins to burn
and the appliance returns to optimum operational temperature. This also applies to the air control. Adjusting it
gradually will help maintain a steady combustion rate. In most instances, you will arrive at the best combustion
air settings yourself as the height and diameter of the chimney, as well as the quality of the firewood are
decisive factors in determining your appliance’s efficiency.
Small hot fires are more efficient than large slumbering ones. Most of the energy in burning wood is released
as a bright flame. The turbulence in the flames creates good mixing between the combustion air and the gases
that are released from the wood as it heats up. The heat of the fire ignites and burns these gases. In contrast, the
dense smoke from a slow, smoldering fire is potential heat energy that can escape up the chimney and either
cling to the chimney flue or pollute the atmosphere.
To gain the most heat from each burn, the fuel should be flaming throughout the burn cycle until it is reduced
to ash. Should any regular slow-burning occur, it is always good practice to burn a hot fire at regular intervals to
keep the chimney clean and dry. When refueling, always place the fuel towards the back of the appliance where
it will burn at a higher temperature.
Types of fuel
Wood needs to be well seasoned before it is burnt. For the best performance, you should use kiln dried wood or
seasoned wood with no more than 20% moisture content. As a general guide, wood should be cut to length,
split and then stacked under cover outside with sides open to the air, for at least 12 months. You can tell that wood
is ready for burning when radial cracks appear at the end of the logs. It is then good practice to store the wood in a
log basket inside your property for a few days prior to its use. The internal width of the firebox of the Ellipse is
330mm, therefore firewood should be no longer than this.
DO NOT burn unseasoned wood in your appliance. DO NOT burn particle board, lacquered, painted or treated
wood, plastics, rubber or liquid fuels. Should the appliance burn any of these materials, the warranty will
become void. This appliance should not be used as an incinerator.

How to light and sustain a fire

MAINTENANCE
Any maintenance of the appliance should only be carried out when the appliance is COLD . Daily maintenance
should be limited to vacuum cleaning the appliance externally or brushing down with a soft brush. Never use
spirits to clean the appliance as this may damage the paint. Regularly check the flue exit from the appliance to
make sure there is no buildup of deposits that may restrict the exit of the flue gases.
The appliance must not be modified in any way. Any changes will invalidate your warranty. Any
replacement parts must be official F2 Fires appliance parts.
The removal of ashes
The ashes should only be removed when the fire is out and has been left to cool completely. The log retaining bar
can be removed for easier access by lifting it up. Wood burns well on a thin layer of ash and leaving this behind
when cleaning will provide protection for the base, insulating bricks and prolonging their life.
Chimney sweeping
The chimney should be swept a minimum of once per year. This must be carried out by a registered and
competent person. If the appliance is used more regularly, the chimney should be swept accordingly. Your
appliance should also be given a visual inspection every time the chimney is swept. These checks should include
the rope seals, door handle, firebricks and baffle. Any buildup of soot and ashes within the appliance should be
removed.
Fire bricks
The fire bricks are manufactured from vermiculite. Vermiculite is a non-combustible fire resistant board with
excellent thermal insulation properties and is safe to handle. As vermiculite is a porous material, it may over time
become worn or damaged. Please handle with care, especially when re-fueling the appliance. The insulation
only needs replacing once it has deteriorated to an extent that it is no longer protecting the steel body of the
appliance from the flames. Cracks in the vermiculite are normal and will not interfere with the efficiency of the
appliance. The vermiculite insulation is not covered by the manufacturer’s warranty.
Glass
If the glass is blackened by soot over time, it can be easily cleaned using one of the many specialist appliance
glass cleaning products available. We recommend wiping the glass after each fire to prevent any buildup of
deposits. This is best done using a paper towel or newspaper to avoid scratching the glass. Using a piece of
newspaper to wipe the inside of the window glass before lighting the appliance each time will also help to
prevent the gradual buildup of deposits and make future cleaning much easier. Glass is not covered by the
manufacturer’s warranty.
Surface
The high temperature paint finish should require no further treatment. However, any damage or wear on small
areas of the paint finish may be remedied using our high temperature aerosol paints. Please read the instructions
on the aerosol carefully before applying.
NEVER attempt any kind of maintenance when the stove is hot or warm.

Problem solving

OPERATIONAL ISSUES
Running Temperature
Thermometers are available that attach to the flue pipe directly above the appliance and aid in running the
appliance at the correct temperature.
150°C-300°C
Perfect. The flue gases should be within this temperature range for the safest and most efficient operation of
your appliance.
Below 150°C
Too low. This will cause the condensation of wood gases and the buildup of tar in the chimney. It can also dirty
the glass and result in the inefficient burning of fuel.
Above 300°C
Too hot. Heat will be wasted up the chimney. Excess heat may damage the appliance or ignite the existing
accumulation of tar, which can result in a chimney fire.
Overheating
Should the appliance be allowed to get too hot and overheat, you should close the air control fully using the
glove. Keep the fire door closed and allow the fire to burn down and the temperature to drop before allowing
air back in.
12
Chimney Fire
In the event of a chimney fire always dial 999 and ask for the
Fire Service. Fully close all air controls and keep the appliance
door closed. Move any combustibles away from the appliance
and chimney. Check any other rooms that the chimney passes
through and move any combustibles away from the chimney
breast. Before using the appliance again after a chimney fire,
the chimney should be thoroughly cleaned and inspected by a
qualified person to ensure further damage has not occurred.
