How Much Space Should I Leave Open Around My Furnace?

November 05, 2019

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

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

Regular furnace maintenance is important to keep your unit operating well. A routinely serviced furnace may run more efficiently, which could reduce your utility bills.

Maintenance often helps us notice troubles before they become expensive. This could help lessen future repair expenses 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 closing off your furnace room, you should take a look at manufacturer specifications and Neptune City statutes for clearance guidelines.

As a general suggestion, your heater 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You also need to ensure the room has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace needs combustion air from the adjacent area. If there’s insufficient air, unsafe gas fumes and deadly 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 install extra openings. This could consist of 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 modern, high-efficiency furnace with PVC piping. Your furnace 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, situate your litter box somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the stinky odors all over your home.

You should also routinely clean around your furnace to block dust from building up.
