The 1810-100 Universal 2BLC Pilot Uni-Kit is designed to replace the obsolete Model 2B and 2BLC Pilot which is no longer in production. The kit includes fittings for 1/4" tubing and an adaptor and fittings to adapt to 3/16" tubing. Each kit comes with a Natural gas orifice installed and includes a separate L.P. gas orifice. The 1810-100 is an aerated, constant burning pilot for main burner ignition. When used with the Uni-Line 1980-1970 Series or similar thermocouples, it provides a heat source for the thermo-electric automatic pilot magnet.
