Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is essential to keep your equipment operating smoothly. A regularly serviced furnace may work more efficiently, which could decrease your energy bills.

Maintenance often helps us spot troubles before they begin. This could help lower future repair expenses and potentially prolong the life of your system.

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 take a look at manufacturer instructions and Dayton statutes for clearance rules.

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 comfortably work on it.

You also need to ensure the room has plentiful 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 insufficient air, unsafe gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is positioned in a tiny room with a gas water heater, you may need to add extra openings. This could involve 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 add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as 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 in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors around your home.

You should also regularly vacuum around your furnace to prevent dust from accumulating.
