How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to run right.

Your furnace can overheat if it doesn’t have enough space. It also makes it hard for our professionals to perform furnace repair.

Regular furnace maintenance is important to keep your equipment working well. An annually serviced furnace may work more efficiently, which could reduce your heating costs.

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

So how much room 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 consult manufacturer specifications and Gresham laws for clearance guidelines.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This lets our service professionals to easily repair it.

You also need to ensure the area has plentiful airflow and ventilation, especially if you have an aging furnace with a metal flue.

This model of furnace draws combustion air from the nearby area. If there’s inadequate air, unsafe gas fumes and toxic carbon monoxide could back draft into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to put in extra 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 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 function as laundry and storage space, you should keep yours free of clutter 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 in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the smelly odors all over your home.

You should also routinely clean around your furnace to prevent dust from accumulating.
