Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough clearance. It also makes it difficult for our technicians to complete furnace repair.

Annual furnace maintenance is essential to keep your unit running trouble-free. A routinely serviced furnace may work more efficiently, which could reduce your energy bills.

Maintenance often helps us spot problems before they begin. This could help reduce future repair bills and likely lengthen the life of your system.

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer instructions and Lodi ordinances for clearance rules.

As a general suggestion, your furnace should be 30 inches away from furnace room walls on all sides. This permits our service technicians to conveniently work on it.

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

This type of furnace pulls combustion air from the nearby area. If there’s inadequate air, unsafe gas fumes and poisonous carbon monoxide could flow back into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to put in more openings. This could consist of a fully louvered door or vents in the walls.

You don’t need to consider 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 draw 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 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, place your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors all over your home.

You should also regularly clean around your furnace to block dust from developing.
