It is a Valor L1 gas fireplace. There was no fireplace on this wall, so it is a direct vent unit. You can check the Valor website as they have a few models.

We always take into consideration the size of the wall, the cabinetry, the firebox (glass size) when we design the wall. Perhaps this is the best unit for your space or perhaps another gas or electric fireplace would work best.

We often use electric fireplaces in small areas as even the smaller gas units can throw too much heat over time. We specifiy the electric fireplaces that have heat on and heat off functions so you can either have heat with flames or just flames (when it's a bit warm outside but you want a fire anyway!)

Do your research and don't forget to make an Elevation of your fireplace wall to scale, in order to determine sizes of all items in advance of buying the unit.
