FAQ

Filling

How do I fill the tank?
Our special fuel is if fact non-flammable. No dangerous situations will occur even if you pour liquid on to a wick while it is still burning. Still – make sure that filling is done after the flame has been extinguished and the wick has cooled down.

Igniting

You can light the wick with a TenderFlame lighter or any other fireplace lighter, even with ordinary matches. Point the lighter to the wick for about 10 seconds. In the beginning the flame is light blue. The flame will rapidly increase and after a few minutes it will reach its full size.

1. Lilly

Max filling volume is 250 ml for Lilly 10 and 150 ml for Lilly 8. Slowly pour the fuel in to the container. Important – do not fill over the brim of the burner (the metal plate on which the wick is fixed). Excess fluid should be poured out (you can pour excess liquid in to your sink) If the unit is over filled, the flame can grow larger than intended. You can easily extinguish the flame by placing a saucer or lid over the flame. Without oxygen the flame dies out.

Crocus

Max filling volume is 200 ml. Slowly pour the fuel into the container. Important – do not fill over the brim of the burner (the metal plate on which the wick is fixed). Excess fluid should be poured out If the unit is over filled, the flame can grow larger than intended. You can easily extinguish the flame by placing a saucer or lid over the flame. Without oxygen the flame dies out.

2. Cafe Alu, Tulip 14 cm og 18 cm

Max filling volume is 300 ml. Slowly pour the fuel into the container. Important – do not over fill the burner (the metal plate on which the wick is fixed). Excess fluid should be poured out If the unit is over filled, the flame can grow larger than
intended.

3. TenderFlame 90

Max filling volume is 500 ml. Slowly pour the fuel into the container at the end of the wick where you find the tank gauge. It is a small red indicator. Make sure the wick is lightly soaked with fuel before you light it. The tank is full when the tank gauge points straight up. Make sure not to overfill.

4. Tenderflame 90DL (with separate filling opening)

Wet the wick with TenderFuel before use. Slowly pour the liquid over the entire wick. Then, fill the tank through the opening. The tank is full when the red mark/pin in the tank gauge is over the top plate. Max filling volume is 500 ml.

5. TenderFlame 180

Max filling volume is 1000 ml. Slowly pour the fuel into the container, over the wick, at the end where you find the tank gauge. It is a small red indicator. The wick should be wet in TenderFuel before you light it. The tank is full when the red tank gauge points upwards. Make sure not to overfill the burner.

6. Tenderflame 180DL (with separate filling opening)

Wet the wick with TenderFuel before use. Slowly pour the liquid over the entire wick. Then, fill the tank through the opening. The tank is full when the red mark/pin in the tank gauge is over the top plate. Max filling volume is 1000 ml. Do not over fill.

Extinguishing

7. Lilly and Crocus Simply blow out the flame – just like a candle.

Café, Rose, Amaryllis, Tulip 14 and 18 cm Place the extinguishing lid over the wick. The flame will die out in a few seconds. Leave the extinguishing lid on the burner until the next time you are going to enjoy it.

8. Tenderflame 90 and 180 burners?

Place the extinguishing lid between the glasses and over the wick. The flame will go out in a few seconds.
Leave the extinguishing lid on the burner until next time you intend to use it. If the flame does not extinguish at the first attempt, just lift it up and then replace it over the wick.

9. Does TenderFuel have any odour?

TenderFuel presents no odour when it burns.

In general terms, everything that burns may have a light smell due to impurities such as soot in the air. The metal and glass as it become hot may also give of some light odour. The big burners may also emit a slight odour the first few times they are used. You may also experience some smell as the wick is ignited and when the flame is being extinguished. TenderFlame will, as a rule, burn without any odour when the combustion
is complete.

The human sense of smell is very acute and we are able to detect odours even in infinitesimal quantities. A new born baby has 25 million cells for detecting odours. The sense of smell becomes weaker with age and vary from person to person. How we react to different odours varies from one person to the next.

Puffing

11. My wick gives of small “puffs”?

Very occationally one can experience small droplets that burst out from the flame followed by some smoke. This can occur if the burner hasn’t been used for some time and there has been liquid left in the tank. The puffing is caused because the liquid absorbs some of the humidity in the air after a while. When this humidity is heated up by the flame it can create small water droplets that puffs and releases vapour as steam.

To avoid this you should always add some new liquid in the tank and soak the wick before use. If the burner hasn’t been used for a while it is better to replace the fuel. This puffing doesn’t present any risk or danger.

12. What is TenderFuel?

Our fuel is 100% safe to use. The fuel is not classified as flammable, due to its high flashpoint – 104 degrees Celsius. The liquid is brought to the top of the wick by capitulary effect and the fuel only burns on top of the wick – not in the tank.

TenderFuel is not classified as toxic. We have undertaken thorough testing and documentation at accredited test laboratories and institutes and at acclaimed universities. Teknologisk Institutt (KIWA TI), Svensk Provning (RISE) and TÜV in Germany. All have reached the same conclusion: TenderFuel is safe to store, transport and burn. TenderFuel presents no risk for humans, animals or nature. At complete combustion the flame burns with no odour and does not emit particles considered to be harmful in any surcumstanse.
