Empty fireplaces getting in the way (11)
I believe the answer is:
meaningless
'empty' is the definition.
(similar in meaning)
'fireplaces getting in the way' is the wordplay.
'fireplaces' becomes 'ingles' (I've seen this in another clue).
'getting in' is an insertion indicator.
'the way' becomes 'means' (synonyms).
'ingles' going into 'means' is 'MEANINGLESS'.
(Other definitions for meaningless that I've seen before include "Empty" , "not at all significant" , "Without significance" , "having no worthwhile quality" , "Futile" .)
