I have a fan kit on my gas fireplace, but it doesn't seem to blow much air.

Your fan kit has a rheostat control (like a light dimmer). You can get more air from your fan by making sure the fan control is turned up to the desired level. The fan control can be found in the control area behind the lower louver of the fireplace, or on a wall switch with rheostat. We also provide optional remote controls which can control your fan speed from your favorite chair! Your dealer can help you with adding a remote control.
