How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough room. It also makes it difficult for our professionals to perform furnace repair.

Regular furnace maintenance is important to keep your unit operating smoothly. An annually serviced furnace may run more efficiently, which could decrease your utility bills.

Maintenance often helps us notice troubles before they become expensive. This could help lessen future repair costs and possibly lengthen the life of your furnace.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should consult manufacturer specifications and South Beloit and Belvidere statutes for clearance requirements.

As a general rule of thumb, your system should be 30 inches away from furnace room walls on all sides. This lets our service experts to comfortably replace it.

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

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

If your furnace is placed in a tiny room with a gas water heater, you may need to put in supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to assess airflow and ventilation as much if you have a newer, 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 items 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 smelly odors throughout your home.

You should also routinely clean near your furnace to block dust from developing.
