The SF-xxx-x bio-ethanol burner series from ENJOYABLE WARMTH is a
premium burner that will fit into your design perfectly. Its safety features
are unrivaled. Using bio-ethanol as a fuel means it’s suitable in any place –
no need for exhaust systems, gas pipelines or constructive adjustments to
your building.
The burner combines ease-of-use (operate it using a smartphone app, an
infrared remote control, or buttons on the heater itself; have it filled
automatically by the filler system) with safety (the filler system
automatically stops when the tank is full – no spilling; the burner includes
multiple safety sensors) and design (it can be installed anywhere – nicely
build it in at the place you like; it provides nice yellow flames).
Being CE-tested and certified, you can trust on its safe operation.
1.2. How it works
Bio-ethanol is (almost) pure alcohol, made out
of (waste of) natural products like e.g. sugar
cane. When bio-ethanol burns, its rest products
are carbon-dioxide (CO2) and water (H2O). We
(humans) also breath out carbon-dioxide. There
is no risk of carbon-monoxide, as with gas
burners, which is toxic and dangerous.
In order to get a nice yellow flame, the bio-ethanol is dispersed into the
burner with computerized precision. The fuel tank is separate from the
burner, ensuring safe operation. One of the potentially dangerous
Page 4 / 49 Version 1.0
Owner’s manual SF-xxx-x series bio-ethanol burner
operations with other bio-ethanol burners is spilling during filling. The SFxxx-x series has got an automated filler system, which ensures no fuel is
spilled, and the tank is not over-filled.
Since there are no toxic waste products, the burner can be installed
anywhere, without requiring an exhaust system. And because it can be
easily filled by means of a jerry can, it also doesn’t require a gas line either.
This gives you optimal flexibility for placing the burner.
Since any fuel uses oxygen to burn, the bio-ethanol burner also uses
oxygen. If the room would be fully closed, this would mean the oxygen
would be used up. Therefore, some ventilation needs to be in place: either
through a window, through a mechanical ventilation system or by other
means. In the unlikely case that not enough oxygen can be provided, the
burner will shut itself down because it has got a built-in CO2 safety sensor.
1.3. Where to use
The SF-xxx-x bio-ethanol burner can be placed anywhere where there is
electricity (to power the fuel pump and its control unit). It needs to be
installed in a dry place, with at least 20cm free space to each side, and
50cm free space above the burner. When using it outside, make sure the
burner cannot get wet, and that the power remains connected at all times.
1.4. Features
The SF-xxx-x bio-ethanol burner is available in lengths from 61cm up to
210cm (with custom sizes and more lengths available as customization
option). Its features are listed below:
Nice design: can be included in any design you like

2. Installation
2.1. Operating conditions
The burner can be operated within the following restrictions:
The environment should be dry (no bathroom, no outdoor usage
unless properly protected against moisture).
Enough fresh air should be available (in very well isolated houses:
ensure ventilation is sufficient).
Avoid heavy airflow (e.g. because of fans) in the room where the
burner is positioned.
The burner will produce heat, but should not be used as the
primary heating system for a building.
Make sure the size of the burner fits the size of the room (see § 1.5
Available models).
2.2. Safety precautions
The following safety precautions should be taken into account:
Use liquid ethanol only.
Keep the burner out of reach of children and pets.
Do not place any items on top of or inside the burner.
Do not leave the burner unattended while burning.
Do not touch the burner while it’s still hot.
Flammable materials, such as curtains and decorations should stay
clear of the fireplace for at least 1 meter.
It’s extremely dangerous to use bio-ethanol car fuel or any other
fuel not developed for bio-ethanol burners.
Page 7 / 49 Version 1.0
Owner’s manual SF-xxx-x series bio-ethanol burner
Refilling the burner is best done with the hose and automatic
filling system. If manually filling, always use a funnel.
Never fill the unit while it’s burning or it’s still hot – allow at least
30 minutes after shutting down the burner for the fuel tray to cool
down.
Spilled ethanol must be removed with an absorbent tissue and
cleaned with water in order to prevent ignition outside the burner
reservoir.
Do not smoke while filling the burner.
Always have a fire extinguisher in the proximity of the fireplace.
Store any fuel containers away from the burner and any other heat
source.
Never try to blow out the flame in order to put it out – this
provides additional oxygen and will only increase the flame.
Do not modify the burner in any way.
2.3. Installation requirements
The bio-ethanol burner should be installed in an environment that meets
the following characteristics:
The burner should be placed horizontally – make sure it is properly
leveled.
Do not install the burner in a bathroom or sleeping room.
Insert the burner into fireproof materials only.
2.4. Mounting options
The burner can be inserted into any non-flammable material, such as
stone, steel or sheet materials specifically developed for high
Page 8 / 49 Version 1.0

temperatures. The burner can also be inserted into a fire frame which can
be ordered as accessory:
2.4.1. Cut-out sizes
When designing your own fireplace, you need to have a groove for the
burner to be inserted into:
The sizes for the cut-outs are listed below. Note: some minor variation
may exist, so always use the actual burner to create the cut-outs.

3. Operation instructions
3.1. Filling the fuel tank
WARNING! Make sure that the burner has cooled down before filling the
fuel tank – allow at least 30 minutes after operation before
filling the fuel tank!
WARNING! Always fill the fuel tank; never pour fuel directly into the
burner element.
Use the filling hose to fill the fuel tank. Put 1 side
into the jerry can with bio-ethanol, and the other
side onto the nozzle on the burner. Then, press the
fill button.
The fill button will pump the fuel from the jerry can into the fuel chamber.
It will automatically stop when the fuel chamber is full. Then, disconnect
the filling hose.
If you fill using the manual fuel inlet, ensure you do not spill any fuel. In
case fuel is spilled, clean it according to the instructions in § 2.2 (Safety
precautions). When the alarm buzzer sounds, stop fueling immediately.
