If you’re finishing your basement or enclosing your furnace room, you should research manufacturer instructions and Saint Marys statutes for clearance requirements.

As a general suggestion, your heater should be 30 inches away from furnace room walls on all sides. This lets our service technicians to comfortably work on it.

You also need to make sure the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

Although furnace rooms function as laundry and storage space, you should keep yours free of clutter that could be fire hazards.

This includes:

  • Clotheslines
  • Cleaning or laundry products
  • Gasoline, paint or paint thinner
  • Rags and papers
  • Wood scraps and sawdust
  • Used filters
