U S E A N D C A R E Natural Gas Connections and Service Regulators Above 1/2 psi. Prior to 1998, all residual gas service regulators were set with an outlet pressure of 7 inches water column.

C A U T I O N Natural Hazard – Spiders FACT: Sometimes spiders and other small insects climb into the burner tubes attached to the burners. The spiders spin webs, build nests and lay eggs. The webs or nests can be very small, but they are very strong and can block the flow of gas. Clean burners prior to use after storing, at the beginning of grilling season, or after a period of one month not being used. An obstruction can result in a “flashback” (a fire in the burner tubes). The grill m
