Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough clearance. It also makes it difficult for our specialists to perform furnace repair.

Routine furnace maintenance is crucial to keep your unit running smoothly. A regularly serviced furnace may heat more efficiently, which could reduce your energy costs.

Maintenance often helps us spot troubles before they become expensive. This could help lessen future repair expenses and potentially extend the life of your system.

So how much clearance 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 take a look at manufacturer instructions and Zelienople statutes for clearance requirements.

As a general suggestion, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service technicians to easily replace it.

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

This model of furnace draws combustion air from the surrounding location. If there’s insufficient air, unsafe gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is placed in a little 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 think about 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 add 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 elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors around your home.

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