Canned Foam Insulation


I hope this is the right place to ask this question.

I have a fireplace. Not brick just sorta like an insert. Condo built around 1985 Maine coast. It was inefficient so I had a Jotul Gas Stove installed. The little thing puts out heat nicely. The company stuffed fiberglass insulation into the fire box of the fireplace and put a black tin cover over the opening. The fireplace is trimmed with regular wood door moulding.

My problem is that I don't think they closed the damper before they stuffed that insulation in there. There is a wicked draft all around that tin (sheet metal I guess you would call it) insert.

Should I use black caulk around
it or can I use that spray foam insulation. The stove is a B-vent stove. The stove is about 2 inches from the insert.
Is that spray foam insulation safe in such a hot area. What about caulking? I don't want a fire.

Can I paint the spray foam once it's dry?

Most of the foam in a can products are not meant to be used in high heat applications. You might be able to find a suitible product at a fireplace type specialty dealer

to answer your other question, cured foam can be painted

Companies like Rutland and Red Devil both make high heat rated products that are typically sold under names like "fireplace caulk". you can probably find it at farm and fleet type stores, hardware stores, and even lowes and depot

I would call back the installation company and have them remedy the issue.
It would help if you knew the exact issue. Speaking to contractors with some understanding of the correct way of installing this unit is better them vague generalizations which can be explained away.
Do you have the installation instructions for this unit?
If not, get them off the internet and check what they did.
