I need some help quickly with a few general zero-clr fireplace questions:
Is a stone or precast concrete cap supported over a chimney considered a "decorative shroud" and as such would it not be allowed with a listed fireplace/chimney system? Can that type of look only be used with masonry fireplaces?
What do most people do to cap the top of the chimney especially covering manufactured stone veneer? Hearth/cap stones, mortar bed, fabricated sheet metal? How do you spec all these?
Firestops are required at floor/ceiling penetrations. Is this required if the chimney is mounted exterior of the building envelope entirely?
What is the proper way to handle insulation (Western Washington) for a fireplace contained completely within the building envelope (i.e. centered in a room as a focal piece) and externally mounted?
All help is greatly appreciated.
