A small, efficient gas fire that slides into the B-vent fireplace you already have. Quick Facts • Heating Capacity: Approx. 550–1,100 sq ft• Efficiency: 74% (steady state)• Viewing Area: 310 sq in• Fuel: Natural gas; propane conversion kit available.• Controls: Basic wall thermostat included; handheld remote and flame adjustment optional.• Fan: Included (variable speed). Who It’s For You have an older builder-grade B-vent gas fireplace, a Firesong or a Montigo, that drinks gas and barely warms the room. You do not want to open the wall. The Energy E18E is made for that box: it fits inside it with a faceplate cut for your exact model, or into the cavity once the old firebox is removed. If you want a real, sealed, high-efficiency fire in a small room without construction, this is the one. Choose a zero-clearance fireplace instead and you are buying a demolition as well. What Makes It Special The E18E is built around the fireplaces it replaces. Low-profile black faceplates are made for each Firesong and Montigo model, so the insert finishes clean against the old opening, and a wider plate covers the cavity when the whole firebox comes out. Inside, a linear burner runs under either a five-piece log set or a bed of black, copper, or clear crystals, so the same small insert can read traditional or contemporary. The blower is standard, the glass is flush, and the brick or black enamel panels behind the fire are your choice. Possible Downsides • It is small; a large open room will want the Energy U31 or a bigger insert.• The faceplate must match your old fireplace model, so measure and identify it before ordering. If you want to turn a tired B-vent fireplace into a sealed, efficient fire without opening the wall, the Energy E18E is the right decision. The room finally gets warm, and nobody can tell what used to be there. The E18E offers model-specific low-profile faceplates, a ceramic log set or black, copper, or StarFire crystals, brick or black enamel panels, a driftwood log set, a remote control, flame adjustment modules, and flue adaptors for the original venting.
