How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is crucial to keep your equipment operating well. A routinely serviced furnace may run more efficiently, which could decrease your heating bills.

Maintenance often helps us discover troubles before they begin. This could help lessen future repair bills and likely extend the life of your system.

So how much clearance should your system 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 Beaverton statutes for clearance rules.

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

You also need to check the room has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace pulls combustion air from the nearby location. If there’s insufficient air, unsafe gas fumes and toxic carbon monoxide could back draft into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to put in more 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 function as laundry and storage space, you should keep yours free of items 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 elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors all over your home.

You should also frequently clean around your furnace to prevent dust from building up.
