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

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

Routine furnace maintenance is crucial to keep your unit working well. A regularly serviced furnace may work more efficiently, which could decrease your energy bills.

Maintenance often helps us notice problems before they start. This could help lessen future repair bills and possibly extend the life of your furnace.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should research manufacturer directions and Wilmington laws for clearance guidelines.

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

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

This model of furnace pulls combustion air from the adjacent location. If there’s inadequate air, unsafe gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is located in a small room with a gas water heater, you may need to add more 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 add air.

Keep Combustible Materials A Safe Distance 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, put your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors around your home.

You should also regularly sweep around your furnace to stop dust from building up.
