How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can shut down if it doesn’t have enough space. It also makes it challenging for our specialists to perform furnace repair.

Annual furnace maintenance is crucial to keep your unit operating well. A routinely serviced furnace may work more efficiently, which could reduce your heating expenses.

So how much area 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 consult manufacturer instructions and Lincoln ordinances for clearance rules.

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

You also need to make sure the space 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 insufficient air, dangerous gas fumes and poisonous carbon monoxide could flow back 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 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 draw 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 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, place your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors around your home.

You should also frequently sweep around your furnace to stop dust from developing.
