Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is essential to keep your equipment operating well. An annually serviced furnace may heat more efficiently, which could decrease your energy expenses.

Maintenance often helps us notice problems before they become expensive. This could help lower future repair expenses and likely lengthen the life of your unit.

So how much room should your system 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 directions and West Valley City statutes for clearance requirements.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This permits our service technicians to conveniently work on it.

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

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

If your furnace is positioned in a tiny room with a gas water heater, you may need to put in supplemental 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 unit uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function 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, put 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 all over your home.

You should also frequently sweep around your furnace to block dust from accumulating.
