I am thinking of taking to molding to the edge of the chimney not around it.
Crown molding around chimney.
The range hood store offers the best range hood crown moldings compatible with zline range hoods.
The molding will be a little over 6.
1 run the horizontal piece 90 off the ceiling.
Crown molding helps your zline hood fit perfectly.
Be sure to measure twice and order the correct extension that matches your hood at the range hood store.
2 wrap the crown around the chimney.
If you have a particularly short ceiling or high ceiling these extensions are for a customized fit.
With various options of design per compatible range hood series you are able to pick your style.
Browse crown molding at the range hood store.
No convenient way to attach that i can think of yet but possible 3 build a thin cornice box around the chimney with 1x4 and install the crown around this provides a nailing surface.
1 just cut the crown so it buts up against the stainless chimney.
I am in the middle of kitchen reno and have a stainless chimney hood exhaust fan being installed between upper cabinets.
The chimney dimensions vary by ceiling height and hood type.
