[1] If the fire simply burns on a bed of ash, it is a wood-only fuelled appliance, and cannot be used for coal or peat.
Multi-fuel stoves have been common in the northern United Kingdom, Ireland, and continental Europe since the 19th century.
In smoke control areas, stoves must burn smokeless fuel or have their design approved by DEFRA.
They are lightweight and burn liquid fuel such as white gas, kerosene, or even automobile petrol, depending upon the stove model.
Liquid fuel is mixed with air (vaporized) and channeled through an opening called the "jet" toward the burner.
Some designs require "priming" before use, by pumping the stove several times to release air and fuel through the jet.
