Dual-voltage heating capability
The RS78-LINEAR-V2 provides 5,000 BTU with standard 120V operation and is 240V capable for up to 10,000 BTU. The supplied product information does not provide a supported square-foot heating-area rating, so room coverage should not be estimated from the documented BTU values alone.
Expansive Linear Design with a Taller Viewing Opening
The Redstone V2 Linear 78" is designed for large fireplace walls and modern interiors where a broad horizontal fire presentation is the priority.
The RS78-LINEAR-V2 measures 77-3/4" wide × 24" high × 9-7/8" deep and provides a substantial 73-1/4" wide × 18-11/16" high viewing opening.
Modern Flames combines the taller viewing opening with a highly improved LED flame pattern, helping create a more visually prominent linear fireplace presentation.
Nominal size vs. actual width: Although identified as the 78" Redstone V2 Linear, the documented overall width is 77-3/4".
