Expected frigid temps are prompting a timely reminder from State Fire Marshal Jim Smith:

“Hopefully, the number one thing has already been done and that is to make sure that your furnace has been checked on by a certified mechanic to make sure that it’s working properly, that all the burners are working properly and most importantly, the flue is not clogged.”

Smith also recommends Minnesotans with wood-burning stoves or chimneys attached to fireplaces make sure those are clean as well.
