I have a century FW240007 wood stove and it has a blower on the back. I bought it used and it appears if there was a blower switch, it is broke off and i just plug it in to run the blower. My question, is should i always run the blower? Does it make a big difference? We have a small floor fan blowing the cold air from one side of the house towards the stove and have been running the blower all the time. Any thoughts? Thanks.
