Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough space. It also makes it difficult for our technicians to perform furnace repair.

Annual furnace maintenance is essential to keep your unit working well. A regularly serviced furnace may run more efficiently, which could reduce your utility costs.

Maintenance often helps us spot problems before they begin. This could help lower future repair costs and possibly extend the life of your system.

So how much clearance 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 directions and Carpentersville laws 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 easily replace it.

You also need to ensure the space has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace draws combustion air from the adjacent area. If there’s not enough 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 add extra openings. This could involve 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 up-to-date, 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 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, 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 stinky odors around your home.

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