My vented gas logs are sooting, is there a problem?

Soot will occur naturally from the smoky yellow wood-like flame.  Unfortunately, there is not a "fix" for this and it will happen with all vented pan burners used with gas logs, FireBalls, FireShapes or FireStones sets.  

A vented pan-type burner system has the advantage of providing a very realistic replication of a wood-like flame without the need to cut, stack or carry wood, worry about sparks or chimney fires, or clean up ashes. The trade-offs for the yellow flame are the production of soot and the corresponding requirement that the damper be open and the chimney be venting properly in order to allow the soot and products of combustion to be vented out of the firebox. As it says in the instruction manual, under “Customer Responsibility”, we state “Your gas log is designed to burn with a natural smoky yellow flame that produces soot.”


Many people feel that the soot makes the logs look more natural, just like a real wood fire. For those who do not, the soot can be either brushed or vacuumed away. Alternatively, and more easily, after burning the logs for a few minutes to get them hot, you can spray the sooty area with water from spray bottle. The soot dislodges and goes up the chimney.
