Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is important to keep your unit running well. A regularly serviced furnace may run more efficiently, which could lower your utility bills.

Maintenance often helps us notice problems before they start. This could help lessen future repair costs and potentially prolong 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 Oxford laws for clearance guidelines.

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

You also need to ensure the space has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace pulls combustion air from the nearby location. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to add 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 up-to-date, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to add 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, place your litter box somewhere else. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors all over your home.

You should also routinely clean around your furnace to stop dust from developing.
