Crossword Genius

I will avoid various coal-fires out of doors (8)

Ross

I believe the answer is:

alfresco

'out of doors' is the definition.
(synonyms)

I can't explain the rest of the clue.

(Other definitions for alfresco that I've seen before include "Outside" , "Outdoors, meal perhaps" , "In the open air" , "where it's cool" , "out of the house" .)

I've seen this clue in The Times.
