If you’re remodeling your basement or closing off your furnace room, you should research manufacturer specifications and Omaha ordinances for clearance guidelines.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This lets our service professionals to easily repair it.

You don’t need to assess airflow and ventilation as much if you have a modern, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms are often also used for laundry and storage space, you should keep yours free of items 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

If you have a cat, situate your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors around your home.
