This is used for firing the stove (5)
I believe the answer is:
range
'stove' is the definition.
(synonyms)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for range that I've seen before include "Cooking appliance" , "Compass - scope" , "Tract of grassy land for livestock" , "Chain of mountains" , "Cattle country - mountains - scope - stove" .)
