| • | If you never use your fireplace, plug and seal the chimney flue. |
| • | Keep your fireplace damper closed unless a fire is going. Keeping it open allows warm air to escape through the chimney. |
| • | When you use the fireplace, reduce heat loss by opening dampers in the bottom of the firebox (if provided). |
| • | Install tempered glass doors and a heat-air exchange system that blows warmed air back into the room. |
| • | Check the seal on the flue damper and make it as snug as possible. |
| • | Add caulking around the fireplace hearth. |
| • | Use grates made of c-shaped metal tubes to draw cool room air into the fireplace and circulate warm air back into the room. |
