Fireplace Mantel Surround and Building Codes


Hey everyone hoping you can help me understand the building code for fireplace mantel surrounds. This is what I'm looking to order for my fireplace:



I want to make sure it meets building and fire code.

The way I read the code is that there needs to be at least 6" clearance from the firebox opening to the surround, and if less than 12", then it cannot project more than 1/8" for every 1" of clearance. So in other words if my surround projected 1" from the brick face then I'd need to have a clearance of 8".

Seems straightforward but I've seen websites and forums that say that's only for above the firebox - not the sides. The sides only need to be 6".

So can anyone clarify for me if there is any difference between the clearance above the firebox versus the sides?

The surround I want is pretty standard and has a projection of 1.5" which would mean that my clearance needs to be 12" which is double what most people have.

I assume/hope I'm not reading the code correctly.

Thanks!

I just spoke to the fire chief in my town and he confirmed my interpretation of the code. So basically I need to be 12" from the firebox on top AND sides. Doesn't that seem like a huge amount of space though? I've never seen a fireplace with that much space...

It's been years since I looked up the specs--but I have always used 12"(above) --and it never looked odd---

12" above i'm sure looks fine. i'm just worried about 12" on the sides. the place i'm buying the mantel from tells me the most common clearance on the sides is 6-8" which seems about right to me - but against code apparently!

my town in NJ uses the standard international residential code. so do people just ignore the code when installing these things?

thanks. i'm guessing this was a factory-made fireplace you bought? there are different rules in the building code for those. my fireplace is original to the house.

Yes....double sided. But I would have thought it would be much the same for you.

Re: Fireplace Mantel Surround and Building Codes


You dont necessarily have to be 12 inches from the firebox. Though 12 inches really is not that much, but it ultimately depends on how far the mantel will stick out from the wall. Your manual should have a specs or a diagram on how deep the mantel can be vs the clearance from the firebox. Sides of the firebox clearances are usually about 8 inches, but again it depends on how far you fireplace surround will stick out from the wall.

Re: Fireplace Mantel Surround and Building Codes


I just finished building a mantel and had to go through all of this stuff as well. So its all still pretty fresh in my brain.
