take it off. you will never be happy. maybe you can run a thin wire behind it to loosen it. if it hasn't completely set yet, it should come off. it will ruin the wall before the wood so be prepared to patch. I have the same type of mantle and the bottom of it sits at 41" (which is fine because the FP is inoperable).

but even lowering yours 7" would help.

However, maybe w/whatever stone or tile you've chosen, it won't look quite that bad. Not sure since I can't really get perspective. what's the stone you've chosen?

the way it is now, it's prob going to look like this picture when done (this mantle is thinner, but you get the idea w/the space )

Lower it. I don't think that code even applies with this kind of fireplace.

Yes, even these have clearance requirements found in the installation instructions that must be followed per code.

Any mantle that heavy will look strange until a hearth is added to balance it, even if you lower it.

Mine is called zero clearance gas insert.

"Mine is called zero clearance gas insert" - you had better go read your installation instructions.

In the fireplace world, "insert" refers to a unit designed to go INSIDE an existing masonry fireplace. Therefore, the clearances to combustible materials on 5 sides of the unit are taken care of by the existing masonry (noncombustible) construction.

"Zero Clearance" is a totally different category of fireplaces than "Inserts". It is generally considered an oxymoron to use both term for the same fireplace.

A "zero clearance" fireplace is a standalone unit that can have wood framing and drywall very close to 5 sides of the unit. (No masonry protection)

Here are the clearance requirements to the first "zero clearance gas fireplace" that came up in a Google search. Clearances for the Front Face (exposed area) of the unit, and mantle are NOT "zero".

Lower it. Any damage to the mantle or wall can be fixed.

Even " zero clearance" has a fireproof code, most times, ( 10" on top, 8" on two sides Usually a mantel needs 12" above the heat source; You have the wrong firebox for what you wanted in a final look. Very Sorry for the 20 hour labor of love, but either live with it, reduce the mantel thickness to 1/2............or remove it. You needed the firebox at floor level......no matter what mantle or stone. A Mendota zero clearance/ full view firebox below. The brick is not there just for decoration.....: )

My fireplace was a gas starter wood burning fireplace with a huge brick surround that was vented out of a chimney. The stack that led to the chimney was a pipe that accessed the master bedroom fireplace with a log set. When we remodeled we direct vented the lower fireplace and installed the insert, there was no masonry surround. We do not need a hearth because it is not a wood burning fireplace and because it is completely enclosed (it operates with a remote) only the wall board above the unit needs to be fire rated. We just have stacked stone, but we could have had a mantle anywhere. There is no upward heat. Its basically a gas heater.

"There is no upward heat. Its basically a gas heater." - another oxymoron.

Heat always rises. Even an electric cooktop is required to have clearance to anything combustible above it, and a cooktop is not designed to heat the whole room. Even gas water heaters have minimum clearances to combustible materials adjacent to, and above them.

"We had talked about having the top of the mantle 63" above the floor due to code and it being a combustible material." - clearly, the OP's fireplace has clearance requirements.

IMO the mantel does not work at all I would use that piece for a shelf somewhere else and hang a piece of art above the fireplace

The mantle won't be ruined by repositioning.

If this mantel is 6'5" off the floor, hanging it two inches lower is not going to make a meaningful difference visually or in terms of space above -- like a drop in the bucket. You didn't say how thick it is, so maybe it's significantly lower. I agree that stone might make the difference, but it does seem odd to need a ladder to reach the mantel, at whatever height!

Here's the current mantel height with stone added underneath. It looks proportional, anyway...

Here I have moved it down by its own thickness. Is that worth whatever destruction would be required of wall and/or beam?

Great mockup ACM. That stone makes all the difference.

Following.

greenfish 1234 is correct

remove mantle and use elswhere

stone to the ceiling

install a hearth

I appreciate everyone's advice. ACM, I especially appreciate the mock up. It really helped. We recognize that this is our error in not doing the proper homework based on the sheer size of our (huge) mantle. We are getting options to repair it, at our cost. We still don't know why the firebox was installed at 12" above the floor, and probably never will. And that's OK. Greenfish, I have running list of boo boo's that I am letting go as well, but I don't think this can be one of them. I just feel the mantle is way too high and doesn't leave the proper room above for white space, decor, etc. I would be fretting about it and wishing I would have changed it while I had the chance. We are looking into ripping out the mantle and installing a much smaller one at a lower height (which will still meet code), as well as doing stone to the ceiling to help potentially eliminate some costly drywall repair.

"What code has you measure from the FLOOR, not heat source??" - many architects and GCs like to translate everything into AFF for consistency when relaying these things to the people who actually do the work. I am sure the installation instructions read differently. Obviously, it was not very consistent this time.

I am dead set on a mantle. I have never had a fireplace and have been dreaming of a fireplace and mantle since we decided to build. We will figure it out.

I don't think you're over reacting. Have them remove it. Patch the wall, and reinstall it where you want it to go. I think mistakes are going to happen when building or remodeling a home, and you have to deal with each situation as it comes. This one doesn't seem very hard to fix, and I think you deserve to have it the way you want it, especially when you have personally invested as much time and energy as you have into the mantle. There may be other mistakes that you will decide you can live with. Hope everything turns out well.

If you're going to do stone to the ceiling, I would keep this mantel and lower it as much as possible to stay within code. If you do anything thinner, I think it will look out of proportion to the fireplace wall.

Cute kitty, greenfish!

If you moved the wood down and put a steel plate on the bottom of it for safety would that be allowed?

@virginia lynn - "If you moved the wood down and put a steel plate on the bottom of it for safety would that be allowed?" Apparently, per the installation instructions, it can come down about 6.5" as is. A steel plate attached to the bottom is not an approved means of any further clearance reduction since the heat will travel right through it.

Section G2409

https://codes.iccsafe.org/public/document/code/553/9854210

That looks good. No to the corbels. Maybe just stone to the mantle.

The things you've put on it are good scale for the mantel and the wall but I would definitely move it down if it's at all possible. I really feel it would just be more aesthetically pleasing and look more proportional.

Adding the hearth was a good idea to balance it out. It looks great!

Came out really nice! Glad you're happy with it.

Code for mantel is minimum 12 inches from an opening.

That is code for a masonry fireplace. A factory built fireplace is subject to different requirements based on testing by an independent laboratory to conform to certain standards based on the designed output of the unit.

Since the OP will not post the brand and model of fireplace, we would have no clue what it says in the installation instructions.

So happy for you, the fireplace looks great. Fred S, I love all the technical knowledge that you have. Thanks for sharing with us.

So happy you found a solution! We are dealing with the opposite problem where mantel was installed too low given it’s 2” deep. As soon as we turned on fireplace, the paint bubbled. We have two possible solutions:

1. Ask for a 1” deep rebuild of top breastplate so we can preserve up to 46” from floor and try to keep side columns
2. Stick with 2” depth and cut mantel to the top blue painters tape line 48” and remove side columns altogether. Any advice? Note: there are marble tiles behind all of this millwork so exposing is no problem. I just want the right proportions.
