Fires can be fueled by [[activate|activating]] the fuel and then selecting ''Burn'' on the fire's right-click menu. Alternatively, leaving the fuel inside the fire till the fuel decays from fire damage also works.
Burn time is dependent on the [[QL]] of the container and the total [[weight]] of the fuel being added. As a guide, 20 30 kg is the maximum effective amount of fuel. Any more fuel added above that amount will still be accepted and burned, but will not add to the burn time.
:* [[Birch]] wood is 2x more effective than non-birch wood (1kg of birch = 2kg of fuel)
Examine a [[fire container]] to check how much fuel is remaining.
