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 space. It also makes it challenging for our technicians to perform furnace repair.

Annual furnace maintenance is important to keep your unit operating smoothly. A regularly serviced furnace may work more efficiently, which could reduce your utility expenses.

Maintenance often helps us spot problems before they begin. This could help reduce future repair expenses and potentially extend the life of your system.

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should research manufacturer instructions and Pella ordinances for clearance requirements.

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

You also need to make sure the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.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 space. If there’s not enough air, hazardous 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 newer, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as 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, place your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also regularly clean by your furnace to stop dust from accumulating.
