How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough room. It also makes it hard for our professionals to complete furnace repair.

Annual furnace maintenance is crucial to keep your unit working smoothly. A routinely serviced furnace may run more efficiently, which could lower your utility bills.

Maintenance often helps us notice problems before they begin. This could help reduce future repair bills and possibly lengthen the life of your system.

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should take a look at manufacturer directions and McMurray ordinances for clearance rules.

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

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

This kind of furnace pulls combustion air from the nearby space. If there’s insufficient air, unsafe gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to put in more openings. This could consist of 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 furnace uses one pipe as an exhaust vent and the other to draw 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 items 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 deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

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