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

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

Regular furnace maintenance is crucial to keep your equipment operating smoothly. An annually serviced furnace may run more efficiently, which could decrease your utility expenses.

Maintenance often helps us notice troubles before they start. This could help lessen future repair expenses and possibly extend the life of your furnace.

So how much clearance should your furnace really have?

How Much Space Should My Furnace Have?

If you’re remodeling your basement or sealing off your furnace room, you should research manufacturer instructions and Swanton statutes for clearance rules.

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

You also need to check the space has ample airflow and ventilation, especially if you have an aging furnace with a metal flue.

This type of furnace needs combustion air from the nearby location. If there’s insufficient air, dangerous gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is placed in a little room with a gas water heater, you may need to put in supplemental 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 Flammable Items 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, put your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors around your home.

You should also regularly vacuum near your furnace to block dust from building up.
