Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to run right.

Your furnace can get too hot if it doesn’t have enough space. It also makes it challenging for our professionals to perform furnace repair.

Regular furnace maintenance is essential to keep your equipment running well. A routinely serviced furnace may heat more efficiently, which could reduce your heating costs.

Maintenance often helps us spot issues before they become expensive. This could help lower future repair costs and possibly extend the life of your furnace.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should consult manufacturer specifications and Moline laws for clearance requirements.

As a general rule of thumb, your system should be 30 inches away from furnace room walls on all sides. This permits our service experts to conveniently work on it.

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

This model of furnace pulls combustion air from the surrounding area. If there’s insufficient air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is located in a little room with a gas water heater, you may need to put in extra openings. This could involve 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 up-to-date, 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, place your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors around your home.

You should also regularly clean near your furnace to block dust from developing.
