How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is crucial to keep your equipment running smoothly. An annually serviced furnace may heat more efficiently, which could decrease your heating expenses.

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

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should take a look at manufacturer specifications and Des Moines statutes for clearance rules.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This allows our service technicians to comfortably repair it.

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

This kind of furnace pulls combustion air from the adjacent location. If there’s not enough air, unsafe gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is positioned in a little room with a gas water heater, you may need to add 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 unit uses one pipe as an exhaust vent and the other to draw in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as 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, put your litter box in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors throughout your home.

You should also regularly sweep by your furnace to prevent dust from accumulating.
