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 complete furnace repair.

Annual furnace maintenance is essential to keep your unit working 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 lessen future repair bills and potentially prolong the life of your unit.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should research manufacturer specifications and Dresden statutes for clearance requirements.

As a general suggestion, your heater should be 30 inches away from furnace room walls on all sides. This permits our service experts to easily work on it.

You also need to ensure the room has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace pulls combustion air from the adjacent location. If there’s not enough air, dangerous gas fumes and toxic 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 put in more openings. This could consist of 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 system 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 elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

You should also frequently sweep by your furnace to stop dust from accumulating.
