Valor G3.5 Gas Insert, Natural Gas

The Valor G3.5 gives an existing fireplace a big, clear gas fire, with a window 23-5/8 inches wide and 15 inches high. Pick birch, driftwood, or traditional logs, then a liner and front to suit your room, and you have a fireplace that looks finished instead of patched.

This 700RN is the current natural gas engine, with an input range of 13,000 to 26,000 Btu/h. It includes AutoFire and the Valor 10 remote, and it runs on battery power, so it doesn't need household electricity to operate as a heater. The fuel bed, liner, front, and backing plate are ordered separately.

Why Homeowners Choose the G3.5

• Works without household power. Battery operation means it doesn't need household electricity to run as a heater.
• Legend design lineage. Valor says the G3.5 carries four generations of its Legend insert design.
• Build your own look. Choose from three log sets, four liners, and several fronts.
• AutoFire and Valor 10 included. Both come standard with the 700R engine.

This listing is the Valor 700RN engine, the current G3.5 direct vent gas insert for natural gas. The fuel bed, liner, front, and backing plate are sold separately.
