6” Range Fan 7” Vent Cap

Timothee | Posted in Construction Techniques on

I need to install a range fan with 6” air outlet to a 7” wall vent with a 90 degree elbow and don’t have much room for a reducer. The 7” vent is stuccoed in firmly to the exterior wall or I’d switch it to 6”. Any thoughts? Could I buy a low profile reducer anywhere? Would it be weird to run a 6” duct through to the end of the 7” vent? Thanks for any tips!

    I would run the 6" right through that would keep the manufacturers engineers happy
