The stove is not intended to be a heater, but rather a decorative "cozy fireplace".
It is thus not subject to furnace regulations, even if - as in every kind of combustion - heat is produced as a by-product.
There must be adequate ventilation in the room it is used in!
The same caution must be exercised as when using candles, lighters, or matches.
Detailed safety measures and instructions are included with each article or can be requested in writing.
