How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to run right.

Your furnace can shut down if it doesn’t have enough room. It also makes it challenging for our specialists to complete furnace repair.

Regular furnace maintenance is crucial to keep your equipment running trouble-free. A regularly serviced furnace may heat more efficiently, which could decrease your energy expenses.

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

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

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

This model of furnace draws combustion air from the nearby area. If there’s insufficient air, hazardous gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to add extra openings. This could include a fully louvered door or vents in the walls.

You don’t need to assess airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your unit 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 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 elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors around your home.

You should also frequently clean near your furnace to block dust from developing.
