Hello, yes you can. just make sure the space of your opening is good for the new unit, The opening is fire rated and the T.V is 30 inches away.

Here is current fireplace. Plan is to remove all the stone and make a recessed area above for TV and put new more modern tile or stone all around. I don't know if I should take the current fire box out and then buy an ignes insert which is expensive or just set one of the other ignes units into the space? I appreciate your expert advice. Thanks so much.

Using one of our units would be a cleaner look. If you use a firebox it would be much easier for you. The whole unit is already set up with all the fire proofing you need. If you are getting an insert then you would need to create the box yourself with fire rated materials.

could you show me a photo of what you recommend?

[Ignis Single Sided Bio Ethanol Fireplace Insert FB2400-S, Black Firebox[(https://www.houzz.com/products/single-sided-bio-ethanol-fireplace-insert-black-prvw-vr~43527638)

This is the one I am thinking of. Is it as easy as taking the current box out and putting this in??

The photo of the unit you posted would work good. That is our fireboxes. You could also use a burner insert but it would be much more work for you.

ok i ordered the firebox monday and cannot get any info from houzz the phone number on the site just rings and rings then a computer answers it and then hangs up. is this legit order??

please contact me asap.

Does it put out heat, or just decorative?

hello, It puts out heat.

Roughly how tall does the opening need to be above the burner insert? Is 30" the night for the TV for the burner insert too?

Hello, The opening needs to be as big as the actual unit. Here are the installation instructions so you can get a better understanding.
