Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to heat properly.

Your furnace can overheat if it doesn’t have enough clearance. It also makes it challenging for our technicians to perform furnace repair.

Regular furnace maintenance is essential to keep your system operating smoothly. An annually serviced furnace may heat more efficiently, which could decrease your energy bills.

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

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should take a look at manufacturer specifications and Des Moines laws for clearance rules.

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

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

This type of furnace needs combustion air from the nearby location. If there’s inadequate air, unsafe gas fumes and deadly carbon monoxide could leak into your home.

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

You don’t need to consider airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your unit 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 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, put your litter box elsewhere. 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 by your furnace to stop dust from accumulating.
