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 get too hot if it doesn’t have enough space. It also makes it hard for our professionals to complete furnace repair.

Regular furnace maintenance is important to keep your system running well. A regularly serviced furnace may work more efficiently, which could lower your energy expenses.

Maintenance often helps us notice issues before they begin. This could help lessen future repair expenses and likely 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 closing off your furnace room, you should consult manufacturer specifications and Auburn 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 experts to easily replace it.

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

This type of furnace needs combustion air from the adjacent space. If there’s inadequate air, dangerous gas fumes and toxic carbon monoxide could flow back into your home.

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

You don’t need to assess airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your system 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 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 in another room. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors around your home.

You should also regularly sweep near your furnace to stop dust from accumulating.
