Kneel awkwardly, installing new pet shelter (6)
I believe the answer is:
kennel
'pet shelter' is the definition.
(eg a dog kennel)
'kneel awkwardly installing new' is the wordplay.
'awkwardly' is an anagram indicator.
'installing' indicates putting letters inside (I've seen this in other clues).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'kneel' is an anagram of 'kenel'.
'kenel' placed around 'n' is 'KENNEL'.
(Other definitions for kennel that I've seen before include "housing for boxer, say" , "Dog shelter" , "Dog's shelter" , "Canine home" , "Doghouse" .)
