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 room. It also makes it hard for our professionals to perform furnace repair.

Annual furnace maintenance is essential to keep your equipment running smoothly. An annually serviced furnace may heat more efficiently, which could reduce your utility bills.

Maintenance often helps us discover issues before they start. This could help lessen future repair expenses and possibly prolong the life of your system.

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should research manufacturer specifications and Savage laws 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 conveniently work on it.

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

This type of furnace needs combustion air from the surrounding area. If there’s not enough air, dangerous 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 consider 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 draw in 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, situate your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors around your home.

You should also regularly vacuum around your furnace to prevent dust from accumulating.
