The oven burner flames are too large and yellow, causing a lot of black soot in oven. I've tried adjusting the air flow. It was all the way open, but that made it worse.
Answer Hello Gordon,
This sounds like you are not set up for the gas you have connected to the unit. There is natural gas and LP gas. Each one use their own set of orifices and set up procedures to ensure the complete consumption of the gas. Without proper setup, poisonous gasses are produced, so the unit has to be set up properly to provide normal operation. Let us know what gas is provided to the unit and we will let you what parts need to be changed and/or adjusted to provide proper gas consumption and normal operation.
