How Much Space Does My Furnace Need?

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

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

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

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double 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

If you have a cat, put your litter box in another room. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors throughout your home.
