Why are my gas fire pit flames coming from my burner large, yellow, and dirty?

Direct Spark Ignition (DSI) burners are set up specifically for one fuel type (liquid propane or natural gas) and to operate as cleanly and efficiently on that one fuel. If the flames are extremely large and bright, and there is soot at the tips of the flames, the burner is most likely set up for natural gas but liquid propane is being supplied to it. Verify what gas type the burner was designed to operate on and what gas is being supplied to the system. A natural gas DSI burner will have a sticker on the control box that says: “This control has been converted for use with natural gas.”

If the fuel type of the burner and the fuel being supplied to the burner match, the unit may be receiving gas at a higher pressure than the unit is rated to handle. OGC DSI Burners are rated to a maximum of ½ PSI (14 in. WC) gas pressure and issues with gas supply should be handled by a licensed gas professional. Contact OGC for more information.
