Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to work correctly.

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

Regular furnace maintenance is important to keep your equipment running smoothly. A regularly serviced furnace may heat more efficiently, which could reduce your utility expenses.

Maintenance often helps us discover troubles before they become expensive. This could help lessen future repair expenses and possibly extend the life of your unit.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should consult manufacturer instructions and Manassas laws for clearance requirements.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This permits our service professionals to comfortably replace it.

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

This kind of furnace draws combustion air from the adjacent area. If there’s inadequate air, hazardous gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is placed in a small room with a gas water heater, you may need to install more openings. This could include 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 double 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, put your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors around your home.

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