If you’re finishing your basement or sealing off your furnace room, you should research manufacturer directions and Hamilton ordinances for clearance guidelines.

As a general recommendation, your furnace should be 30 inches away from furnace room walls on all sides. This lets our service professionals to easily replace it.

You don’t need to think about airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to draw in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of things 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
