Montigo DelRay 36" Linear Direct Vent Gas Fireplace, Zero-Clearance

The Montigo DelRay DRL3613NI-2 is a 36½-inch linear direct vent gas fireplace built around a concealed burner design — meaning you get an unobstructed ribbon of flame over a bed of ice fireglass, with none of the hardware stealing the show. Six pounds of fireglass are included, and if your aesthetic leans toward driftwood, speckled stones, or alternative glass media, those are available as optional upgrades.

At 16,000 BTU/hr with a 71% efficiency rating, this fireplace is sized for ambiance-forward living spaces where you want genuine warmth without overpowering a room. The Proflame 2 IPI ignition system keeps the pilot off when the fireplace isn't in use, so you're not burning gas just to keep a standing flame alive. A battery backup ensures the system stays operational even when the power goes out — a detail that earns its keep on a cold night.

Standard equipment here is legitimately well-appointed: black reflective glass panels deepen the visual field of the firebox, halogen downlighting adds drama above the flame, and remote-controlled fans give you hands-free heat distribution. A micro-mesh safety screen is included, with an optional Invisimesh screen available for a cleaner sight line if preferred.

Installation is zero-clearance, with just 4 inches required to combustibles on the sides, and the unit can be framed right down to the glass opening on combustible materials. Framing dimensions are 43⅜ inches wide by 33 11/16 inches tall by 14¼ inches deep — straightforward numbers for your contractor to work with. The 4-inch inner / 7-inch outer direct vent system supports a maximum vent run of 34 feet (combined vertical and horizontal), giving you real flexibility in where this unit lands in the home. The BVK35 Kit is a compatible direct vent adapter for this model.

The DRL3613NI-2 ships as a natural gas unit and is convertible to propane via an available NG to LP Conversion Kit — handy if your installation site or plans change. It's rated for altitudes up to 4,500 feet above sea level and carries mobile home approval, which opens up installation contexts that many linear fireplaces simply can't accommodate.

Optional trim kits and Cool Wall management systems — including the Cool Wall Release (included) and the Cool Wall Advantage Kit (available separately) — round out a thoughtfully specified package. This is a fireplace that arrives with the essentials already handled and room to customize from there.
