Montigo L52 See-Through Linear Fireplace, 47" Viewing Area

The Montigo L52 gives you 47 inches of width and 21¾ inches of height in a see-through direct vent fireplace — which is to say, two rooms get to argue over who enjoys the view more. Part of Montigo's PHENOM L-Series See Through collection, this unit is built for architects, designers, and homeowners who want a genuine architectural centerpiece rather than an afterthought.

At 40,000 BTU/H (11.73 kW) input on natural gas, the L52 delivers serious heat output through a linear contemporary burner bed dressed in ice fireglass — a clean, modern aesthetic that suits everything from mountain retreats to urban penthouses. The overall footprint measures 58¼" wide × 34 13/16" tall × 25 3/16" deep, so your framing contractor will want those numbers early and often.

Installation flexibility is built in from the start. The L52 accepts both top vent and rear vent configurations through Montigo's 5"/8" direct vent system, and can be run with any combination of solid rigid pipe or flex venting per Montigo specifications — an important advantage on complex builds where straight runs aren't always an option. Only Montigo-certified vent components should be used to maintain listing compliance and warranty integrity.

Ignition is handled by IPI (Intermittent Pilot Ignition), meaning the pilot lights on demand rather than burning continuously — a small operational detail that adds up over a heating season. The Proflame 2 BASIC control system manages flame operation with straightforward reliability; it's the kind of system that does exactly what you expect, every time you ask it to.

The see-through configuration is what separates the L52 from the rest of the L-Series lineup. Whether it's bridging a great room and a dining space, or creating a shared focal point between a master suite and a sitting area, this fireplace is designed to be seen — and to make the architecture around it look intentional. At $10,739, it's an investment that tends to define a room rather than simply occupy a wall.
