Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to work properly.

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

Regular furnace maintenance is essential to keep your equipment working smoothly. A routinely serviced furnace may work more efficiently, which could lower your heating expenses.

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

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should consult manufacturer directions and Denton ordinances for clearance guidelines.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This permits our service professionals to conveniently repair it.

You also need to check the room has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace needs combustion air from the nearby location. If there’s inadequate air, unsafe 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 more openings. This could involve 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 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 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, situate your litter box somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the stinky odors around your home.

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