Montigo DelRay Square 34" Direct Vent Gas Fireplace, IPI

The Montigo DelRay Square 34" is a direct vent gas fireplace built around a universal concealed burner — one burner system that handles both natural gas and propane (conversion kit GCA028 sold separately), and accepts traditional logsets or contemporary glass and stone media scenes without any hardware swap. That kind of flexibility is rarer than it sounds.

At 15,000 BTU with a 67.1% efficiency rating on natural gas, this fireplace is designed for focused, comfortable heat delivery rather than raw output. The 4"/7" direct vent system supports a maximum vent run of 34 feet total, with up to 25 feet horizontally and 32 feet vertically — giving your installer meaningful flexibility in routing without compromising performance. Elevation limit is 4,500 feet, so most residential installations across North America are covered.

The Proflame Basic IPI ignition system uses an intermittent pilot, meaning the pilot only runs when the fireplace is in use — a small but meaningful efficiency advantage over standing pilot systems. Battery backup capability means a power outage doesn't leave you staring at a cold firebox.

Installation options here are broader than average. The DelRay Square 34" is approved for outdoor room installations, compatible with mobile homes, and — notably — cabinet installation is permitted on this 34" model specifically. Combined with compatibility for Montigo's Cool Wall Release and Advantage heat management systems, and available trim kits, there's genuine latitude to integrate this unit into a finished space cleanly.

The glass opening measures 29 11/16" wide by 18 7/8" tall, framed within a 36" wide by 40½" tall by 18" deep rough opening. A micro mesh safety screen is included. If you're planning a contemporary media setup, plan for 4 lbs of glass media — ordered separately. Optional accessories include remote controls and circulating fans.

This is not a commercial-rated unit, and it is not rated beyond 4,500 feet elevation. Everything else in the spec sheet, however, points to a thoughtfully engineered fireplace that earns its keep in a residential setting — indoors or out.
