Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is essential to keep your equipment running smoothly. A routinely serviced furnace may work more efficiently, which could decrease your utility bills.

Maintenance often helps us discover problems before they start. This could help lower future repair expenses and likely prolong the life of your unit.

So how much area should your equipment 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 Plainfield ordinances for clearance requirements.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This allows our service experts to comfortably repair it.

You also need to ensure the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace draws combustion air from the surrounding location. If there’s insufficient air, dangerous gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to install more 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 modern, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as laundry and storage space, you should keep yours free of items 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 somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors throughout your home.

You should also regularly clean around your furnace to prevent dust from accumulating.
