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 shut down if it doesn’t have enough room. It also makes it challenging for our technicians to perform furnace repair.

Annual furnace maintenance is important to keep your equipment running trouble-free. A regularly serviced furnace may work more efficiently, which could reduce your energy costs.

Maintenance often helps us spot issues before they begin. This could help lower future repair bills and potentially lengthen the life of your furnace.

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should take a look at manufacturer directions and Elmhurst statutes for clearance guidelines.

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 repair it.

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

This kind of furnace pulls combustion air from the surrounding area. If there’s insufficient air, unsafe gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed 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 think about 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 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 smelly odors around your home.

You should also regularly vacuum near your furnace to prevent dust from developing.
