Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can shut down if it doesn’t have enough room. It also makes it difficult for our technicians to complete furnace repair.

Regular furnace maintenance is important to keep your system working well. An annually serviced furnace may heat more efficiently, which could reduce your utility bills.

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

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should take a look at manufacturer directions and Circleville statutes for clearance guidelines.

As a general recommendation, your heater should be 30 inches away from furnace room walls on all sides. This allows our service experts to conveniently replace it.

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

This model of furnace pulls combustion air from the adjacent area. If there’s inadequate air, unsafe gas fumes and toxic carbon monoxide could back draft into your home.

If your furnace is placed in a small 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 consider 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 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, situate your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors all over your home.

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