Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is essential to keep your unit operating smoothly. An annually serviced furnace may work more efficiently, which could decrease your heating bills.

Maintenance often helps us discover issues before they start. This could help lower future repair costs and potentially lengthen the life of your furnace.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should take a look at manufacturer instructions and Newton laws for clearance guidelines.

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

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

This model of furnace needs combustion air from the nearby location. If there’s inadequate air, unsafe gas fumes and deadly carbon monoxide could back draft into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to install extra openings. This could include a fully louvered door or vents in the walls.

You don’t need to assess airflow and ventilation as much if you have a up-to-date, 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 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, situate your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors throughout your home.

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