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 space. It also makes it challenging for our technicians to complete furnace repair.

Routine furnace maintenance is crucial to keep your unit operating well. A regularly serviced furnace may heat more efficiently, which could decrease your utility costs.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or closing off your furnace room, you should consult manufacturer instructions and Hattiesburg ordinances for clearance requirements.

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

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

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

If your furnace is located in a tiny room with a gas water heater, you may need to put in supplemental 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 up-to-date, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away 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, place your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors throughout your home.

You should also frequently vacuum around your furnace to prevent dust from building up.
