Description

The Firegear OAS-LPK31 Natural Gas to Propane Conversion Kit - 125,000 BTU Match Throw Burners converts a Firegear Match Throw (MT) stainless steel burner system from natural gas to liquid propane. Firegear ships MT burners as natural gas only, so this is the kit you need to run the Sanctuary 1-76 76" fire table (SAN176-MT-N) and Sanctuary 2 39" fire bowl (SAN2-34DBSMT) on propane.

The kit includes the 125,000 BTU LP main burner orifice (OAS-LP31), a 1/2" coupling (SS499-8), a 1/2" x 5" nipple (113-SS4-D5), the U3-8D-S fitting, an LP rating plate sticker and instructions. The orifice must sit at least 6" from the burner connection, which is what the nipple is for; a 90 degree elbow is not included if your gas line needs to turn. Pro Series burners cannot be converted and ship as NG or LP from the factory; TPSI burners use the TPSI-LPK31 kit and AWS burners also need the FG-AWS-PBO-P pilot orifice.
