FireBalls differ from the traditional log set by being a modern alternative for the fireplace. Rasmussen FireBalls offer a contemporary look that compliments most fireplaces both new and old. Fireball sets come in 7 colors, including natural, the color of the concrete, 3 dark colors, and 3 lighter colors, with some more exotic colors like adobe red and beige. This ventless fireball set uses a sleek and shiny stainless steel chassis for an even more modern look. PLEASE NOTE: The Stainless Steel Chassis is a design feature, not an invitation to use this set outdoors. No Rasmussen vent-free set is intended, certified, or warranted for outdoor use.

All vent free fireplace sets are certified to two standards: ANSI Z21.11.2 (Unvented Room Heaters) and ANSI Z21.60 (Vented Decorative Appliance). Use in wood-burning fireplaces or approved vent-free firebox enclosures. These fireplace balls may be used with the damper open, closed or anyplace in between. Vent-Free fireplace sets are supplemental zone heaters, they are not intended for continuous use or whole house heating. 20" set has 30,000 BTU/hr maximum inputs and 24" & 30" have 40,000 BTU/hr maximum inputs.

These ventless fireplace balls have 3 lighting control options as well. ME Manual Control uses a standing pilot, but can only be turned on and off from a valve attached to the set. RE Remote Control uses a standing pilot and a variable flame height remote control. EI Remote Control does not use a standing pilot, but instead only has a pilot briefly with the push of a button for ignition, and also comes with a variable flame height remote control.
