The Grand Canyon OAS-LP31 LP Air Mixer – 125,000 BTU is a liquid propane air mixer sized for select outdoor H-burners and T-burners. Rated for up to 125K BTU, it is specified for use with 30-inch to 36-inch H-burners and the 60-inch T-burner, helping achieve the correct air–fuel mixture for stable, efficient LP combustion and proper flame appearance.
Intended as an OEM service or configuration part, the OAS-LP31 should only be installed on compatible Grand Canyon burner systems and always by a qualified gas technician. Using the correct LP air mixer for the burner size and BTU rating is critical for safe outdoor operation and performance.
