Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can shut down if it doesn’t have enough room. It also makes it challenging for our specialists to perform furnace repair.

Annual furnace maintenance is important to keep your unit working trouble-free. An annually serviced furnace may heat more efficiently, which could reduce your utility costs.

Maintenance often helps us spot problems before they start. This could help reduce future repair bills and potentially prolong the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should research manufacturer instructions and Mankato area statutes for clearance rules.

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

You also need to ensure the room 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 nearby location. If there’s insufficient air, dangerous gas fumes and deadly carbon monoxide could flow back into your home.

If your furnace is located in a little room with a gas water heater, you may need to put in more openings. This could consist of a fully louvered door or vents in the walls.

You don’t need to consider airflow and ventilation as much if you have a modern, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to add 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 deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors around your home.

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