Featuring a 7-inch-deep profile, Heat & Glo’s new Ultra-Slim Revo series offers the thinnest AFUE-rated fireplaces ever made, according to the manufacturer. Designed for ease of installation, the units require no footprint or exterior chase. Once a hole is made in the wall and an SLP venting pipe is set, the lightweight units are hung on mounting brackets. The contemporary series is available in square, linear, and vertical models with interiors of reflective black glass. The slender units quickly fill their compact fireboxes to output heat more quickly than other gas fireplaces on the market, and are capable of producing up to 24,000 BTUs of heat, the company says. The new line also uses direct vent technology to ensure 100% of exhaust gases are expelled outside of the home, and features Heat & Glo’s patented razor burner. www.heatnglo.com
