Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is crucial to keep your unit operating trouble-free. An annually serviced furnace may run more efficiently, which could reduce your utility expenses.

Maintenance often helps us spot problems before they become expensive. This could help lower future repair costs and possibly extend the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

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

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

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

This type of furnace draws combustion air from the nearby location. If there’s not enough air, dangerous gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is located 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 think about 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 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, place your litter box somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors throughout your home.

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