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 difficult for our professionals to perform furnace repair.

Regular furnace maintenance is important to keep your system running trouble-free. A regularly serviced furnace may run more efficiently, which could lower your energy costs.

Maintenance often helps us spot troubles before they become expensive. This could help lessen future repair bills and possibly prolong the life of your system.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should consult manufacturer directions and Perry laws for clearance rules.

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

You also need to make sure the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This model of furnace pulls combustion air from the nearby area. If there’s insufficient air, dangerous gas fumes and deadly carbon monoxide could flow back into your home.

If your furnace is positioned in a tiny room with a gas water heater, you may need to add extra openings. This could involve a fully louvered door or vents in the walls.

You don’t need to consider 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 are often also used for laundry and storage space, you should keep yours free of items 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 corrode your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

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