How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is important to keep your unit working well. A regularly serviced furnace may heat more efficiently, which could reduce your energy costs.

Maintenance often helps us discover troubles before they start. This could help reduce future repair costs and likely prolong the life of your unit.

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should take a look at manufacturer instructions and Augusta laws for clearance guidelines.

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

You also need to check the room 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 area. If there’s not enough air, hazardous gas fumes and deadly carbon monoxide could back draft into your home.

If your furnace is placed in a small room with a gas water heater, you may need to install extra openings. This could include 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 system uses one pipe as an exhaust vent and the other to draw 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 elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors around your home.

You should also routinely sweep around your furnace to block dust from developing.
