Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is essential to keep your equipment operating trouble-free. A routinely serviced furnace may run more efficiently, which could reduce your utility bills.

Maintenance often helps us notice issues before they begin. This could help lessen future repair costs and likely lengthen the life of your furnace.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should research manufacturer directions and Heflin statutes for clearance rules.

As a general rule of thumb, your system should be 30 inches away from furnace room walls on all sides. This permits our service professionals to easily repair it.

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

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

If your furnace is located in a tiny room with a gas water heater, you may need to put in extra 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 draw in 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, put your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors all over your home.

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