Furnace Installation

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 difficult for our professionals to accomplish furnace repair.

Regular furnace maintenance is essential to keep your system running smoothly. A regularly serviced furnace may work more efficiently, which could decrease your energy costs.

Maintenance often helps us spot problems before they begin. This could help reduce future repair expenses and possibly extend the life of your furnace.

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 research manufacturer instructions and Rockford ordinances for clearance guidelines.

As a general recommendation, your furnace should be 30 inches away from furnace room walls on all sides. This permits our service technicians to easily replace it.

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

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

If your furnace is located in a tiny room with a gas water heater, you may need to add 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 furnace 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 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 in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also routinely clean by your furnace to stop dust from accumulating.
