(for transportation) and is regulated by various standards around the world. You must familiarise
yourself and comply with these regulations in order to safely and legally store, handle, decant and
use this fuel.
III. Use only approved Bioethanol fuel that contains 85%-95% Alcohol. Poor quality of fuel may
lead to undesirable results: reduction in reliability, incomplete and inecient combustion, smoke
and odours, residues inside the burner.
IV. Alchemy Ltd is not liable for any damage caused by using the incorrect type of fuel.
2.5 HOT SURFACE HAZARD
I. Due to high surface temperatures, keep children, pets, clothing and furniture away from the

3. Installation
INSTALLATION PARAMETERS
The oor must be level and the Burner positioned on a at surface; this can be perfected with
the adjustable feet. The Burner must only be placed on a non combustible surface and must be
installed in accordance with the outlined safety requirements and clearances.
The basket/ burner must be open and have free air on the front and sides in accordance with the
minimum opening sizes in g.1 and g.2. notably the minimum chamber dimensions are 750mm
wide x 750mm high x 350mm deep.
Ventilation must be around the burner to alleviate any heat build-up on the appliance and its
controls. Excessive heat build-up may cause the appliance to overheat and shut o.
Ensure the enclosure around the appliance is made from non-combustible materials. Any stud
work introduced must be non-combustible materials. Any voids within the breast are recommended
to be ventilated to prevent heat build-up with continuous use.
The Hearth must be within 1mm+/- of levelness to ensure even ame spread across the burner.
3.1 BURNER CLEARANCE
3.1.1 COMBUSTIBLE MATERIALS
• Do not place any kind of combustible materials near the replace, within 1000mm.
• Wood or plastic shelves should be at least at a distance of 1000mm from the replace.
• Non-Combustibles such as stone, metal or ceramics.
• Other non-combustibles such as glass.
Non-Combustible material: A material that does not react to heat.
• Any material which when tested to BS 476-11:1982 (2007) does not ame nor cause any rise
in temperature on the centre (specimen).
• Products classied as non-combustible in tests following the procedures in BS 476-4:1970
(2007).
• Any material classied as class A1 in accordance with BS EN 13501-1:2002 Fire classication

3.3 VENTILATION
It is recommended that you keep a good ventilation of the area in order to ensure a healthy level
of oxygen, please see table below:
Alchemy FB18 Free air under burner (cm²) Minimum Room Size (m³)
50 25
To calculate the room size, measure the Height, length and width and multiply all measurements.
e.g. (L) 6.6m x (W) 3.8m x (H) 2.4m = 60.192m3
Bioethanol combustion releases carbon dioxide (CO2) and water (H2O). The combustion requires
oxygen, therefore the area where the replace is positioned, should have adequate ventilation
with air bricks/vents or any other means, to allow enough fresh air to ensure one room volume
change of air per hour.
While in operation this appliance emits heat, water vapour (H2O) and Carbon Dioxide (CO2),
therefore it is necessary to provide ventilation to the room of the appliance from an external space
as per Document F building regulations.
3.4 LEVELLING THE BURNER
When installing the Bioethanol Fire, level the complete re unit by using the tted adjustable legs.
If the ame does not run along the whole burner side to side while the setting is on high ame,
then it will be necessary to level the burner by adjusting the levelling grub screws.
• A 4mm hex screwdriver or long allen key and a spirit level is required for adjustment of grub
screws.
• If no ame or weaker ames on the left side: Turn the screws of the legs on the right hand side
clockwise from inside the box (to raise the right hand side). Re-ignite the appliance and check
again.
• If no ame or weaker ames on the right side: Turn the screw on the left hand side clockwise
from inside the box (to raise the left hand side). Re-ignite the appliance and check again.
• Repeat the procedure described above until the ames are reasonably level.

Once the glow plug reaches required
temperature and reached by the fuel,
the ame will ignite.
17
4.3 OUT OF FUEL NOTIFICATION AND REFUELLING
When the tank is empty or does not have sucient amount of
bioethanol, a beep and message will appear on the display
screen. You will not be able to ll up the Fuel Tank while ame
is on, because removing top cover will trigger the safety
switch and will extinguish the ames. Following Fuelling
the Fire safety information (see page 8), the fuel tank can
be relled. Fuel level can be monitored by watching oating
orange ball rise through the fuel tank window as it is being
done.
IMPORTANT - when orange ball reaches window do not add
more fuel. It is recommended that provided funnel is used
lling up the tank to avoid spillage into the rebox.
In order to light the Bio Fire the top access panel must be
replaced in its position covering the fuel tank side.
18
5. Safety Systems
The Alchemy Bioethanol range incorporates several safety systems to ensure a complete peace
of mind.
5.1 LEAK DETECTION SENSOR
The Bio Fires have a leak detection sensor
located underneath the burner on the lowest part
of the sump as per image showing the sensor
location. Thus, if there is a leak the re will turn
o itself. A strong beep will sound by the safety
system on appliance.
5.2 OVERFLOW DETECTION SENSOR
The Bio Fires have a leak detection sensor
located underneath the burner on the lowest part
of the sump as per image showing the sensor
location. Thus, if there is a leak the re will turn
o itself. A strong beep will sound by the safety
system on appliance.
5.3 BIOETHANOL FUELLING DETECTION
SWITCH
You will not be able to ll up the Fuel Tank while
the ame is on due to the safety Micro-switch.
Removing top access panel will trigger the switch
and extinguish the ames. A message ‘Lid Open’
will appear on your handset. In order to light the
Bio Fire you must replace the top access panel
in its position covering the fuel tank side.
19
Turn the appliance OFF and isolate the mains supply. Ensure the appliance is fully cold before
attempting to start servicing the appliance. No liability can be accepted by Alchemy Ltd for injury
caused by burning or scolding by a hot appliance.
A suggested procedure for servicing is listed below.
A. Lay out dust sheet on ooring, mask o any special replace materials.
B. Carefully remove the log plate with logs (if purchased with optional Log Plate).
C. Use a Vacuum cleaner to clean the top of the burner and metal top plate.
D. Remove metal top plate and wipe with a dust cloth.
E. Check fuel system inside the rebox for any damage or leaks.
F. Replace metal top plate or log plate.
G. Check the safe operation of the appliance.
6.1 CLEANING THE CERAMICS
Remove the ceramic top plate as detailed above.
Gently clean the ceramics in the open air, using a soft brush and a vacuum cleaner. Where
necessary replace damaged components only with genuine supplier specied parts. Seal any
scrap ceramics in plastic bags and dispose at proper refuse sites. When using a vacuum cleaner,
it is recommended that one with a HEPA ltering system is used.
Re-t the Fire bed arrangement and check the safe operation of the appliance.
It is recommended that the pump top is replaced biannually as part of the service (see

a. There may be waste burning that should not be in the Burner.
b. You are using the wrong fuel (it is essential that you ONLY use Bioethanol).
c. You have placed something around/above the ame that has not been approved or
recommended.
d. If the Burner is empty (the ame is dying) or you have just turned the re OFF, this is normal.
Like extinguishing candles.
e. The quality of Bioethanol you are using is not good enough.
SOLUTION
Turn the Burner OFF and wait until it cools down. Clean/service the Burner and remove objects/
waste. Contact your local distributor for fuel brand recommendation.
a. You have not put enough fuel in the Burner.
b. You have not used the right fuel (it is imperative that you ONLY use Bioethanol).
c. The Burner opening is obstructed, there needs to be adequate ventilation for the ame to start.
d. The Bioethanol is cold and takes time to ignite.
SOLUTION
Check -Stop Code – in the DEVICE menu on the handset for further guidance. Check fuel level by
inspection through the fuel tank window, check type of fuel used. Repeat starting procedure until
the Burner warms up and remains ignited.
Use the isolation switch to prevent the re turning ON. Keep people away from the area. Wipe
up spilt liquid thoroughly using a dry cloth, wipe again with a cloth dampened with water. Avoid
breathing vapours. Ventilate enclosed space by opening windows and doors. If fuel got spilled on
hands, wash thoroughly. ONLY ignite when the area is completely dry and you are certain that all
spilt fuel has been removed. Please refer to MSDS for Bioethanol.
This is likely to be caused by a strong draught blowing on the ame. Locate and remove the
source of the draught (it may be that you have a window/door open or fan operating that is directly
pushing air towards the re). If you cannot remove the source of the draught and the ame is too
volatile, turn the re OFF. You will need to rethink the positioning of your unit before operating
again or install a re screen to minimise the draught eect. Contact your distributor.
