How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough space. It also makes it challenging for our specialists to complete furnace repair.

Annual furnace maintenance is essential to keep your unit running well. A routinely serviced furnace may run more efficiently, which could decrease your utility expenses.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should research manufacturer specifications and Rochester laws for clearance guidelines.

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

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

This kind of furnace needs combustion air from the surrounding location. If there’s insufficient air, dangerous gas fumes and poisonous carbon monoxide could flow back into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to put in supplemental 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 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 double as 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 create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors around your home.

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