How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work properly.

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

Routine furnace maintenance is essential to keep your unit working well. A routinely serviced furnace may run more efficiently, which could decrease your utility costs.

Maintenance often helps us spot troubles before they begin. This could help reduce future repair costs and possibly prolong the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should consult manufacturer directions and York statutes for clearance rules.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This lets our service professionals to conveniently work on 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 kind of furnace draws combustion air from the adjacent space. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to add supplemental openings. This could include 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 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 function as laundry and storage space, you should keep yours free of clutter 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, situate your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also frequently clean around your furnace to prevent dust from accumulating.
