Why The Monessen 42" Attribute Is Worth The Investment
This isn't just a firebox shell, it's built with the same zero clearance design and reversible dual-pattern liner as the 36" model, scaled up to a 42" width that gives homeowners a wider viewing area while retaining the flexibility to switch between a traditional brick look and a herringbone pattern.
The ACUF42-BD specifically addresses the needs of homeowners with a larger fireplace opening who want the same installation flexibility and reversible panel convenience as the 36" model, in a size that fills more wall space.
A Bigger Opening, Same Flexible Design. The reversible liner lets you switch between a traditional brick pattern and a herringbone pattern simply by flipping the panel, while the zero clearance design means this larger 42" firebox can still be installed flush against drywall, wood, or nearly any surface without the clearance requirements of a standard firebox.
Built For Efficient, Flexible Heating
The angled firebox construction is built to push more heat into the room for a cozier space
Safely handles up to 40,000 BTU, giving flexibility in log set and burner selection
Accepts most 18" vent-free log sets and burners, with some 24" sets also compatible, giving a range of display options
Engineered For Practical, Adaptable Installation
Zero clearance construction allows flush installation against drywall or wood, simplifying tight installations
Screens tuck away into hidden pockets to reveal expansive, unobstructed views of the flame
Optional accessories, including a fan kit and lighting kit, can be added later without being required at installation
Real Savings
Zero clearance installation can reduce the framing and clearance work required compared to a standard firebox
A reversible liner avoids the cost of purchasing a second panel to change the interior look down the road
Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately
The Bottom Line Homeowners with a larger fireplace opening who want installation flexibility along with the option to change their fireplace's interior look can't get that combination from a standard fixed-panel firebox. The Monessen 42" Attribute Firebox is built with a zero clearance design and a reversible brick/herringbone liner, so it delivers both installation flexibility and long-term style flexibility in a wider 42" opening. For anyone with a larger fireplace opening who wants room to adapt their fireplace's look over time, this is the firebox built to make it easy.
