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 room. It also makes it hard for our professionals to accomplish furnace repair.

Regular furnace maintenance is important to keep your system operating smoothly. An annually serviced furnace may run more efficiently, which could reduce your utility costs.

Maintenance often helps us spot problems before they start. This could help lower future repair bills and possibly lengthen the life of your furnace.

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should take a look at manufacturer directions and Genoa laws for clearance guidelines.

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

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

This model of furnace needs combustion air from the surrounding area. If there’s inadequate air, dangerous gas fumes and poisonous 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 include a fully louvered door or vents in the walls.

You don’t need to consider 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 pull 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 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 deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors throughout your home.

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