We recommend that you store the paraffin in the original container, preferably in a cool, dark space and away from any heat source. Under these conditions, the fuel can be kept for about 1 year without any problem. Always read the instructions on the label before use. When transporting the jerry can, make sure that the cap is properly closed and that the seal ring is intact. We also recommend that you completely burn off any fuel remaining in the heater at the end of the cold season. Once the heater has been extinguished and has cooled completely, it is best stored in a dust-free environment. At the start of the cold season it is best to begin with fresh fuel and read the user manual’s instructions about starting up your heater again.
