Monessen · Attribute Vent-Free Firebox
A traditional firebox that fits the room you already have
The Attribute brings a real fireplace look to walls where a chimney was never an option. Pick a 32, 36 or 42 inch box, then choose brown or gray interior panels to suit the room.
01 · Panels
Two looks on one panel
Each interior panel is reversible, so you get two brick looks in the box and can change your mind later.
02 · Service
Two-piece hearth
The hearth lifts out in two parts, so the burner and controls can be reached without pulling the log set.
03 · Finish
Clean face with hidden screens
Mesh screens tuck into side pockets, leaving a clean radiant face once the fire is going.
Fuel & Compatibility
This firebox does not burn fuel by itself. Use only an approved gas-fired decorative room heater and its matched log set. The separately selected burner determines fuel, ignition and heat input. Do not burn wood in this firebox.
Product Details
- Clean-face circulating firebox for a tailored built-in appearance.
- Mesh screens tuck into side pockets for an uncluttered view.
- Two-piece hearth provides access beneath the log area.
- Brown or gray reversible interior panels, selected by SKU.
What comes with your order

Questions Before You Order
Are the burner and logs included?
No. This is a firebox listing. Choose a manufacturer-approved burner and compatible log set separately.
Can I use the nominal size as the framing dimension?
No. Use the model-specific framing dimensions and required clearances in the installation manual. The nominal size refers to the firebox family, not the complete installation opening.
