Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is crucial to keep your system working trouble-free. A regularly serviced furnace may run more efficiently, which could lower your utility costs.

Maintenance often helps us notice problems before they start. This could help reduce future repair bills and potentially prolong the life of your system.

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should research manufacturer directions and Menomonie and western Wisconsin statutes for clearance guidelines.

As a general recommendation, your heater 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 check the room has enough airflow and ventilation, especially if you have an older furnace with a metal flue.

This type of furnace needs combustion air from the nearby location. If there’s inadequate air, unsafe gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to add more openings. This could include 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 newer, 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 function 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 elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors all over your home.

You should also frequently vacuum near your furnace to prevent dust from developing.
