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

Annual furnace maintenance is important to keep your system operating trouble-free. A regularly serviced furnace may run more efficiently, which could decrease your energy bills.

Maintenance often helps us spot troubles before they become expensive. This could help lessen future repair expenses and potentially lengthen the life of your furnace.

So how much room 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 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 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 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 unit uses one pipe as an exhaust vent and the other to draw in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as 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, place your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors throughout your home.

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