Open the exhaust port, ignite the exhaust gases and maintain the combustion for 30-60 minutes to fully replace the air inside the furnace.

Upon observing a continuous and stable combustion through the furnace mouth ignition hole, it indicates that the residual oxygen inside the furnace has dropped to a safe level. At this point, you may gradually open the enrichment gas (gas/) valve.

Initially, manually adjust the enrichment gas flow to the preliminary set value. Once the carbon potential starts to respond, switch to the servo motor联动 mode for automatic control.
