How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to work properly.

Your furnace can shut down if it doesn’t have enough clearance. It also makes it challenging for our professionals to complete furnace repair.

Annual furnace maintenance is crucial to keep your system running trouble-free. An annually serviced furnace may run more efficiently, which could lower your utility expenses.

Maintenance often helps us spot troubles before they begin. This could help lessen future repair costs and likely extend the life of your unit.

So how much room 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 research manufacturer directions and Ballwin ordinances for clearance guidelines.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This lets our service technicians to conveniently work on it.

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

This model of furnace draws combustion air from the nearby location. 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 small 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 assess airflow and ventilation as much if you have a modern, high-efficiency furnace with PVC piping. Your unit 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 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, place your litter box in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the stinky odors throughout your home.

You should also regularly sweep around your furnace to block dust from building up.
