Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough room. It also makes it difficult for our technicians to perform furnace repair.

Annual furnace maintenance is essential to keep your equipment operating smoothly. A routinely serviced furnace may heat more efficiently, which could reduce your energy bills.

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

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should take a look at manufacturer specifications and Dresden laws for clearance requirements.

As a general suggestion, your system 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You also need to check the room has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This model of furnace needs combustion air from the nearby area. If there’s not enough air, dangerous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a little room with a gas water heater, you may need to install more 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 newer, high-efficiency furnace with PVC piping. Your unit 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 things 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 elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors all over your home.

You should also frequently clean near your furnace to stop dust from accumulating.
