Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is crucial to keep your system working trouble-free. A regularly serviced furnace may run more efficiently, which could lower your heating expenses.

Maintenance often helps us notice troubles before they begin. This could help lessen future repair costs and potentially prolong the life of your furnace.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer directions and Excelsior Springs ordinances for clearance requirements.

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

You also need to ensure the room has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This model of furnace pulls combustion air from the adjacent space. If there’s insufficient air, hazardous gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is positioned in a little 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 assess airflow and ventilation as much if you have a modern, 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 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 all over your home.

You should also regularly clean near your furnace to block dust from building up.
