How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work correctly.

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

Annual furnace maintenance is essential to keep your unit operating trouble-free. An annually serviced furnace may run more efficiently, which could lower your utility expenses.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should consult manufacturer instructions and Winnipeg statutes for clearance guidelines.

As a general suggestion, your heater should be 30 inches away from furnace room walls on all sides. This lets our service professionals to conveniently replace it.

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

This model of furnace draws combustion air from the adjacent location. If there’s insufficient air, dangerous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to add more openings. This could involve a fully louvered door or vents in the walls.

You don’t need to consider 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 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, place your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors around your home.

You should also routinely vacuum near your furnace to block dust from accumulating.
