  • FireBalls in this set: 

FireBall sets are a contemporary, modern alternative to traditional gas logs. This set of fireplace balls has 7 color options. "Natural" is the tannish gray of the base material. The other colors are our proprietary ceramic stain coloration. We recommend darker colors (Black, Dark Gray, & Brown) as the burner will create soot from the natural, luminous yellow flame. The black soot is more noticeable against the lighter colors (Natural, Adobe Red, Beige, & Light Gray); with the darker colors there is less contrast, so the soot is not as pronounced. 

These fireplace balls have 4 lighting control options as well. Match Lighted comes only with a valve and no lighting source; there is no standing pilot. M 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. VEI 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.  For more information about Lighting Control Options please click on the link.
