Natural Spark Generator (NSG) creates realistic sparks

Kalfire’s patented innovations have taken gas fires to another level, making them a benchmark in the market. One of the latest innovations developed by Kalfire’s R&D team is the Natural Spark Generator (NSG). This technology is available as an option on all our gas fires that feature a Prestige burner. The Natural Spark Generator creates small sparks that escape from the flames and burn out slowly, resulting in an amazingly realistic simulation of a wood fire.
