Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to run correctly.

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

Annual furnace maintenance is important to keep your equipment working smoothly. An annually serviced furnace may run more efficiently, which could decrease your utility expenses.

Maintenance often helps us spot troubles before they begin. This could help reduce future repair expenses 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 updating your basement or enclosing your furnace room, you should consult manufacturer specifications and Greensburg 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 easily repair it.

You also need to make sure the area has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.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 inadequate air, unsafe gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is placed in a small room with a gas water heater, you may need to put in extra 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 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, situate your litter box in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the stinky odors around your home.

You should also frequently clean by your furnace to prevent dust from developing.
