How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to heat 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 important to keep your equipment running well. An annually serviced furnace may run more efficiently, which could reduce your heating expenses.

Maintenance often helps us notice issues before they start. This could help lessen future repair costs and potentially lengthen the life of your furnace.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should research manufacturer instructions and Wyandotte laws for clearance requirements.

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

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

This kind of furnace pulls combustion air from the nearby area. If there’s not enough air, unsafe gas fumes and toxic 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 put in extra openings. This could involve a fully louvered door or vents in the walls.

You don’t need to assess airflow and ventilation as much if you have a modern, 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 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 somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the smelly odors all over your home.

You should also regularly sweep around your furnace to block dust from accumulating.
