Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to run right.

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

Annual furnace maintenance is essential to keep your system operating well. A regularly serviced furnace may heat more efficiently, which could reduce your energy bills.

Maintenance often helps us notice troubles before they become expensive. This could help lower future repair bills and likely extend the life of your system.

So how much area 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 directions and Waterloo ordinances for clearance rules.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This permits our service experts to conveniently repair it.

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

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

If your furnace is positioned in a tiny 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 consider 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 pull 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 somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors around your home.

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