The Stays Lit Ceramic Burner Tube Pilot has been designed and tested by FAV Systems to be used in burner tubes of all sizes and ratings. Our design assurances that the ignition source remains stable and ready to ignite the main burner in any weather condition. The Stays Lit Pilot is very fuel efficient, intense, durable and can easily be adapted to fit most fire tubes. Since the pilot Premix Chamber is mounted outside the main fire tube, it is not suffocated by reverse flows or down drafts. Ignition stability is ensured by continuous flow of fresh primary air from outside.
