Montigo Distinction D4815NI-2 Single-Sided Linear Gas Fireplace, 48"

The Montigo Distinction D4815NI-2 opens with a 48-inch viewing area — wide enough to anchor a room without a single piece of furniture moving to accommodate it. Behind that high-temperature glass sits a concealed linear burner dressed in Ice fireglass, set against a black reflective glass liner that adds depth and amplifies the flame's visual drama without requiring you to do anything except choose your settings.

At 40,000 BTU on natural gas or propane (with a low-fire floor of 28,000 BTU and a 30% turndown ratio), this fireplace is engineered for genuine thermal performance, not just aesthetics. An efficiency rating of 77.49% on natural gas means the heat you're paying for is largely the heat you're feeling. Direct vent operation via a 5"/8" termination keeps combustion air self-contained and interior air quality uncompromised — and if your installation calls for it, the venting can be reduced to 4"/7".

Control is handled by the Proflame 2 remote system with Hi-Lo flame adjustment, and remote-controlled fans distribute warmth without requiring you to leave the sofa. The IPI (Intermittent Pilot Ignition) system lights on demand rather than maintaining a standing pilot, and battery backup ensures operation remains available during a power outage. The multicolor LED uplighting adds an atmospheric layer that's adjustable independently of the flame — useful for evening ambiance when you want the glow without the full heat.

Installation is straightforward by professional standards: framing dimensions are 71½" wide by 49 15/16" tall by 17½" deep, with side clearances of just 4", back clearance of 1½", and zero floor clearance. The micro mesh safety screen is included as standard. Rated for installations up to 4,500 feet in elevation.

The D4815NI-2 ships as a natural gas unit and is compatible with the GCA017 propane conversion kit. For installations where wall-surface heat management is a concern, it accepts Cool Wall Advantage heat management kits (models HDKPD48, HDKSD, HDKSVD, HDKPDFK-1, and HDKPDFK). Optional upgrades include adjustable trim kits, fluted liner packages, and a WiFi phone app control module for those who prefer managing their fireplace from an app rather than a remote. Refer to installation manual XG0222 for full venting and framing specifications.
