Put a Trigger in the fire. Give it a RepeatTriggerTime of 1 second. Make the Trigger set off a SpecialEvent actor that you have put somewhere in your map. The SpecialEvent actor's state should be "DamageInstigator." You should also specify an amount of damage to cause in the SpecialEvent's properties. For a little extra effect, you could even set the DamageType to 'burning.'
Where do I find the actor state?
