Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can shut down if it doesn’t have enough room. It also makes it challenging for our technicians to accomplish furnace repair.

Routine furnace maintenance is important to keep your equipment running smoothly. A routinely serviced furnace may work more efficiently, which could reduce your utility expenses.

Maintenance often helps us spot issues before they start. This could help reduce future repair costs and likely prolong the life of your furnace.

So how much clearance should your system 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 Chatsworth laws for clearance rules.

As a general rule of thumb, your system 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 ensure the room has ample airflow and ventilation, especially if you have an aging furnace with a metal flue.

This model of furnace draws combustion air from the surrounding area. If there’s insufficient air, hazardous gas fumes and deadly 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 extra 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 system 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 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 somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors all over your home.

You should also routinely vacuum around your furnace to prevent dust from developing.
