Orange flame on gas fire

[cwodavids]

My livingroom fire has an orange flame that is causing the bricks/stones that are in the fire to get covered in soot. I'm getting a bit worried that something is not right. The flames just seem to be orange down one side of the fire the other half has a blue flame as normal.

Is this unsafe?

yes it is signs of incomplete combustion or spillage ,get it checked out as it could be producing CO.

Do not use the fire until has been checked by a competant person. Strong possibility it's producing carbon manoxide.
