How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough clearance. It also makes it hard for our technicians to complete furnace repair.

Regular furnace maintenance is essential to keep your equipment running well. A routinely serviced furnace may work more efficiently, which could decrease your heating costs.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should take a look at manufacturer instructions and Macon laws for clearance rules.

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

You also need to ensure the room has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace draws combustion air from the nearby area. If there’s insufficient air, hazardous gas fumes and toxic carbon monoxide could flow back 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 involve 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 modern, high-efficiency furnace with PVC piping. Your system 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 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, place your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors throughout your home.

You should also frequently vacuum by your furnace to stop dust from developing.
