How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is essential to keep your system working well. A regularly serviced furnace may heat more efficiently, which could decrease your heating expenses.

Maintenance often helps us spot issues before they become expensive. This could help reduce future repair bills and likely 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 remodeling your basement or enclosing your furnace room, you should take a look at manufacturer directions and Plover laws for clearance requirements.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This lets our service professionals to easily work on it.

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

This type of furnace needs combustion air from the surrounding area. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a little room with a gas water heater, you may need to add extra openings. This could consist of a fully louvered door or vents in the walls.

You don’t need to consider 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 are often also used for 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, put your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also regularly sweep near your furnace to prevent dust from accumulating.
