Flue can let out gas (10)

I believe the answer is:

flatulence

'gas' is the definition.
(thesaurus)

'flue can let out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'flue'+'can'+'let'='fluecanlet'
'fluecanlet' anagrammed gives 'FLATULENCE'.

(Other definitions for flatulence that I've seen before include "Intestinal gases" , "windiness" .)

I've seen this clue in The Telegraph.
