Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is important to keep your equipment operating well. An annually serviced furnace may heat more efficiently, which could reduce your heating expenses.

Maintenance often helps us spot problems before they start. This could help reduce future repair bills and likely lengthen 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 enclosing your furnace room, you should take a look at manufacturer directions and Mankato area statutes for clearance requirements.

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You also need to check the room has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace needs combustion air from the adjacent area. If there’s inadequate 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 extra openings. This could consist of a fully louvered door or vents in the walls.

You don’t need to assess 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 double 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, place 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 clean around your furnace to block dust from accumulating.
