CAP Electronic Ignition CO2 Generators feature a Pilotless Electronic Ignition instead of a traditional pilot light. A tip-over switch will shut down the fuel to the main burner in the event the unit falls or tips over. Units come with a low-pressure, in-line natural gas regulator or the new type1 style "no-tool-required" propane regulator that makes tank replacement easy. CAP generators operate up to 100° F cooler than competitve products.
