Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough space. It also makes it challenging for our technicians to complete furnace repair.

Routine furnace maintenance is essential to keep your equipment working smoothly. An annually serviced furnace may run more efficiently, which could lower your heating bills.

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

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

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

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

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

This kind of furnace draws combustion air from the surrounding space. If there’s inadequate air, hazardous gas fumes and deadly carbon monoxide could flow back into your home.

If your furnace is placed in a small room with a gas water heater, you may need to install more openings. This could consist of 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 draw in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as laundry and storage space, you should keep yours free of items 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 move the stinky odors all over your home.

You should also regularly clean around your furnace to block dust from developing.
