Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough space. It also makes it hard for our specialists to perform furnace repair.

Routine furnace maintenance is important to keep your system running trouble-free. A regularly serviced furnace may run more efficiently, which could decrease your utility costs.

Maintenance often helps us notice problems before they become expensive. This could help lower future repair expenses and possibly extend the life of your furnace.

So how much area should your equipment 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 Grand Prairie statutes for clearance requirements.

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

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

This model of furnace needs combustion air from the adjacent space. If there’s inadequate air, unsafe gas fumes and deadly carbon monoxide could back draft into your home.

If your furnace is located in a small room with a gas water heater, you may need to put in 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 modern, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to pull 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, situate your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors throughout your home.

You should also frequently clean by your furnace to prevent dust from accumulating.
