Some soot is only natural, but if soot is causing visible stains, it could indicate several problems.
First, the flue could be partially blocked, so some of the exhaust gasses are escaping out from the front of the fixture. Secondly the flame itself may be partially starved for oxygen or fresh air, causing less complete combustion. This is less likely but far more serious as it might cause a buildup of carbon monoxide gas, especially if your flue is also partially blocked.
I am not an expert in H/V/AC by any means, so I am just listing a few things that occur to me. If the flame is starved for oxygen it may become more orange or brown, and may be visibly sooty or smoky, or it may look normal. one clue might be a buildup of soot on the inside of the glass cover.
You should probably have an expert take a look at it.

Turn it off and get an HVAC repairman out there. You heater isn't burning properly. It should be burning a blue flame, if not it will be sooty. Fireplace inserts will burn blue, but cool the flame after that so it looks yellow.
I have had a heater soot up an entire house because it was bad. People don't understand that gas, either natural or propane has soot in it if it doesn't burn hot enough.
Good Luck

Propane is a carbon based product. Gasoline,heating oil,gasoline,diesel,oil and wood are all carbon based products. So is soot.
Not enough air is getting in there for complete combustion so it faintly smokes. The smoke is unburned fuel. So your efficiency is not as good as it should be. You need a seperate air feed pipe to supply air on the fireplace. If the house is very tight, then you need the feeder pipe to come thru the wall from outside to feed the fire.

It is of concern. Soot marks are a sign of impingement or desperately needing a service. Impingement of a flame can cause carbon monoxide.Can also be caused by a blocked Flue.

It could be a number of things - most likely you are getting a downdraft or your fireplace is oversized.

Your fuel \ air mixure is incorrect. You need to make sure you have a blue flame not yellow. I would have it checked out.
