  You know the grease you see on the range hood or ceilings of your kitchen/restaurants above the cooktop/stove?

  Same thing would happen in your chimney, but combined with wood fire ash.

    But the oil is being burnt?

    Is there something from the combustion process that causes issues?

      Nothing burns cleanly in a fireplace, even gas ones except for ventless ones.

      Anything you burn in a fireplace like wood, oil, fat etc. will produce organic compounds that the fire is unable to break down into non-flammable substances because it does not burn hot enough.

      A wood fireplace accumulates creosote, which can build until it is capable of igniting and cause a chimney fire. Oil and fat combust very poorly and will coat the flue with material that is easier to ignite than creosote. This ends up being a hazard worse than just wood byproducts because they can ignite and then set the creosote burning.

      Complete combustion of hydrocarbons is difficult and usually requires specialized equipment for that hydrocarbon. A fireplace is probably for wood (I assume nobody here is throwing cooking oil into a gas fireplace), but it’s not even good at that. Cooking oil will spatter and polymerize
