How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to heat correctly.

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

Regular furnace maintenance is essential to keep your unit operating well. An annually serviced furnace may run more efficiently, which could reduce your utility expenses.

Maintenance often helps us spot troubles before they become expensive. This could help reduce future repair costs and possibly prolong the life of your unit.

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should take a look at manufacturer instructions and Drexel Hill laws for clearance rules.

As a general suggestion, your furnace should be 30 inches away from furnace room walls on all sides. This lets our service professionals to easily replace it.

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

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

If your furnace is placed in a little room with a gas water heater, you may need to put in supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to assess 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 draw in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double 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, place your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors throughout your home.

You should also regularly sweep around your furnace to stop dust from accumulating.
