Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is important to keep your system working well. An annually serviced furnace may run more efficiently, which could decrease your energy bills.

Maintenance often helps us spot issues before they begin. This could help lessen future repair expenses and likely prolong the life of your furnace.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should research manufacturer specifications and Brandon statutes 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 professionals to conveniently repair it.

You also need to ensure the space 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 area. If there’s inadequate air, dangerous gas fumes and deadly 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 put in extra openings. This could include a fully louvered door or vents in the walls.

You don’t need to think about 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 function as 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, place your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors throughout your home.

You should also routinely sweep near your furnace to block dust from building up.
