How Much Space Should I Leave Open Around My Furnace?

November 05, 2019

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

Your furnace can get too hot if it doesn’t have enough space. It also makes it difficult for our professionals to accomplish furnace repair.

Regular furnace maintenance is crucial to keep your system running well. An annually serviced furnace may work more efficiently, which could decrease your utility expenses.

Maintenance often helps us discover problems before they become expensive. This could help lessen future repair costs and possibly lengthen the life of your unit.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should take a look at manufacturer directions and Bartlesville laws for clearance requirements.

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

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

This type of furnace pulls combustion air from the surrounding area. If there’s not enough air, unsafe gas fumes and deadly carbon monoxide could flow back into your home.

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

You don’t need to think about airflow and ventilation as much if you have a newer, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to pull in 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 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, situate your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors throughout your home.

You should also frequently sweep by your furnace to prevent dust from building up.
