Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work properly.

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

Regular furnace maintenance is essential to keep your equipment working smoothly. A regularly serviced furnace may work more efficiently, which could decrease your energy expenses.

Maintenance often helps us discover issues before they begin. This could help lower future repair expenses and possibly prolong the life of your unit.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should research manufacturer instructions and Baltimore laws for clearance rules.

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

You also need to make sure the room has enough airflow and ventilation, especially if you have an older furnace with a metal flue.

This model of furnace needs combustion air from the adjacent location. If there’s inadequate air, hazardous gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is located in a small 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 consider airflow and ventilation as much if you have a modern, 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 are often also used for laundry and storage space, you should keep yours free of clutter 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 corrode your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors all over your home.

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