We've noticed a buildup of soot in the past couple months on the siding of our new-to-us house where the gas fireplace vents. Should we be concerned? Is there any way to reduce the buildup besides not using the fireplace?

Have the fireplace serviced to adjust the fuel/air ratio. If you're burning gas and making soot, it's too rich (excess fuel, not enough air.)
