Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to heat correctly.

Your furnace can shut down if it doesn’t have enough room. It also makes it difficult for our professionals to accomplish furnace repair.

Regular furnace maintenance is important to keep your system working trouble-free. An annually serviced furnace may heat more efficiently, which could reduce your utility costs.

Maintenance often helps us discover problems before they become expensive. This could help reduce future repair expenses and possibly prolong the life of your unit.

So how much clearance should your equipment 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 Moline statutes for clearance requirements.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This allows our service technicians to conveniently repair it.

You also need to ensure the area 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 area. If there’s inadequate air, unsafe gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is placed in a little 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 assess airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your unit 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 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 deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

You should also regularly clean by your furnace to stop dust from building up.
