How do I circulate the heat in my gas fireplace?

Place the box fan on low, facing INTO the space where your fireplace is, blowing the cool air at the unit. This will cause a convection reaction and the hot air will be forced away from the burning unit. If in a small room, the hot air will be moving out the door into larger spaces in no time.

How do I disperse the heat from my gas fireplace?

The blower fan can efficiently disperse the heat generated by the gas fireplace into the room. Simply put, the fan circulating cold room air around the hot fireplace before pushing it back into the room. The result is a steady cycle of warm air that heats your space!
