How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work properly.

Your furnace can overheat if it doesn’t have enough room. It also makes it difficult for our specialists to perform furnace repair.

Routine furnace maintenance is crucial to keep your equipment operating trouble-free. An annually serviced furnace may heat more efficiently, which could decrease your utility bills.

Maintenance often helps us discover problems before they begin. This could help reduce future repair expenses and potentially prolong the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should take a look at manufacturer instructions and Belton statutes for clearance rules.

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

You also need to make sure the room has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace draws combustion air from the surrounding area. If there’s insufficient air, unsafe gas fumes and deadly carbon monoxide could back draft into your home.

If your furnace is positioned 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 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 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 corrode your furnace’s heat exchanger. Plus, the furnace could move the stinky odors around your home.

You should also frequently clean near your furnace to stop dust from building up.
