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 room. It also makes it challenging for our specialists to complete furnace repair.

Routine furnace maintenance is important to keep your system operating trouble-free. An annually serviced furnace may work more efficiently, which could reduce your heating costs.

Maintenance often helps us discover problems before they begin. This could help reduce future repair costs and potentially prolong the life of your furnace.

So how much clearance 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 East Bernard laws for clearance guidelines.

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

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

This model of furnace pulls combustion air from the surrounding location. If there’s inadequate air, unsafe gas fumes and deadly 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 put in supplemental 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 newer, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double 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 create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors all over your home.

You should also frequently sweep around your furnace to stop dust from accumulating.
