Grand Canyon 300K Propane Orifice

The Grand Canyon OAS-LP12 Propane Orifice is a high-capacity 300,000 BTU LP orifice engineered for outdoor stainless steel burners and larger 30-inch to 48-inch fire rings. Designed to deliver the correct fuel flow for big, open flame presentations, this part is specified when configuring compatible Grand Canyon fire ring systems to operate on liquid propane.

This OAS-LP12 orifice includes 3/4-inch connections, making it suitable for higher-volume gas supply lines commonly used on large fire pits and fire features. It is typically used as the main burner orifice in LP setups and is also included in several LP conversion kits that adapt natural gas systems to propane. Installation should always be performed by a qualified gas professional, following the burner’s installation manual and local codes.
