You should make sure that you have a power source close by your fireplace in order to plug in any fireplace blowers you decide to run. Usually, you can expect a blower to require one hundred and ten volts of power. You may need to have an electrical outlet installed so you do not end up with an extension cord running across the floor.
Many furnaces are also equipped with glass doors that are especially necessary when the fireplace is warming up and can not deal with smoke and thus lets the bitter smell in the room. The glass cover helps to prevent it. The doors can be swinging or lifting. By the way, furnaces with a fireproof door are safer than open grates, and allow you to manage the flow of warm air much better and easier. The only drawback is that sometimes the heat-proof glass may be covered with soot.
