Valor G3 Gas Insert, Natural Gas

The Valor G3 is a gas insert with a long track record. Valor introduced it in 1991, and the 739M engine keeps that design going with a wide choice of fuel beds: Classic, Legend, or Traditional logs, Pebble Beach Driftwood, or a bed of rocks. It's a simple way to turn an existing wood-burning fireplace into a gas fire you control with a remote.

This 739MN runs on natural gas and turns down to 6,500 Btu/h, so you can run a low, gentle flame when you want one. AutoFire and a Valor Plus remote are included, and Valor describes the G3 as a radiant fireplace that warms the room directly without relying on a fan or electricity. The fuel bed, liner, front, and surround are sold separately.

What Makes the G3 739M Different

• Low turn-down on natural gas. Input runs from 6,500 to 24,000 Btu/h, so the flame can go from gentle to full.
• Five fuel bed options. Pick from three log styles, driftwood, or rocks to set the look.
• Battery powered. It doesn't need household electricity to operate as a heater.
• AutoFire and remote included. The engine comes with AutoFire and a Valor Plus remote and wall holder.
