Montigo Mahana 42" Outdoor Gas Fireplace, 304 Stainless Steel

The Montigo Mahana 42" is a ventless outdoor gas fireplace built from 304 stainless steel — the same alloy grade used in commercial kitchens and marine hardware, because outdoor environments are not known for going easy on finishes. It outputs 28,000 BTU through a linear concealed burner, with quartz firebeads as the standard media and a viewing window that measures 37¼" wide by 14⅛" tall. That wide, low aperture is not an accident; it's the visual signature of the Mahana series.

Installation is straightforward for a fireplace at this tier. The unit is listed for outdoor wood frame construction and finishing, with a framing footprint of 42" wide by 27¼" tall by 11⅝" deep. Ventless operation means no chase, no liner, and no venting run to plan around — though the control box does require a dedicated 120VAC, 60 Hz, 5A GFCI circuit. Gas supply connects via a ½" or ⅜" inlet port at 5.5" W.C. for natural gas. The Honeywell HSI (Hot Surface Ignition) system handles lighting duties reliably without a standing pilot, and the unit is compatible with remote control systems for those who prefer to manage their fire from the comfort of a chair.

Zone heating reach is rated up to 10 feet, which makes the Mahana a genuinely functional heat source for an outdoor seating area, not just a decorative one. Whether you're finishing a covered patio or building a full outdoor room, the framing dimensions are designed to work within standard wood-frame construction — and the finished result can be dressed in a range of optional enclosure colors including stainless steel, carbon, graphite, dune, and cerulean.

The accessory catalog for the Mahana 42" is substantial. An LED backlighting kit (MCLEDVO) adds ambiance behind the flame. A pedestal base and protective cover are available for freestanding or off-season applications. Decorative media options include speckled stones and a driftwood log set (LGS59). For installations where propane is the practical fuel choice, a propane conversion kit (PL42VOLE) is available separately.

Montigo backs the Mahana with a 15-year limited warranty — notably longer than what you'll find on most outdoor hearth products at any price point. At $6,929.00, this is a serious outdoor fireplace built for installations meant to last.
