Help identify this insert please

[Moddoo]

This is for sale locally.
I am considering buying it, even though it is a bit too tall to fit into my fireplace.
I am hoping to modify it to fit.
The seller says it is a box design, with a variable speed blower.
Not a tube type heat exchanger.
I don't need it to heat the house. I just want to get some heat output when using the fireplace for ambiance.

Please let me know if you can identify this, and any info you might have on it.
It is an hour drive to go see it.

Thank you.
