How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to heat right.

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

Routine furnace maintenance is important to keep your unit working well. A routinely serviced furnace may work more efficiently, which could reduce your heating expenses.

Maintenance often helps us notice troubles before they begin. This could help lessen future repair bills and possibly prolong the life of your unit.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should take a look at manufacturer instructions and New Castle ordinances for clearance guidelines.

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

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

This kind of furnace pulls combustion air from the surrounding area. If there’s not enough air, dangerous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to put in more openings. This could include 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 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 Away from Your Furnace

Although furnace rooms double 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 move the smelly odors around your home.

You should also regularly vacuum by your furnace to prevent dust from accumulating.
