That doesn't appear to be 1-K grade water-clear kerosene! If that's some diesel or home heating fuel/oil mix, I would expect problems with flame level, smell and possibly dangerous fumes, and premature wick failure.
Thank you for your input and concern! All kerosene fuel sold here is of blue color. The kerosene container in the video is sold by Kerosun company itself for the sole use in its heaters. We have used more than 200 liters (about 53 gallons) before the wick started having problems... As mentioned in the manual premature wick failure can be caused if you leave the heater to run out of fuel every time. (although doing that periodically can clean carbon deposits from the wick).
@@varnasfix ...interesting! I've never encountered blue-dyed kerosene, only red-dyed, and not for quite some time. Thankfully, several fuel stations near me sell 1-K grade, water-clear Kerosene.
