Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough clearance. It also makes it difficult for our technicians to accomplish furnace repair.

Regular furnace maintenance is essential to keep your equipment operating well. A regularly serviced furnace may run more efficiently, which could reduce your heating expenses.

Maintenance often helps us notice problems before they become expensive. This could help lessen future repair expenses and possibly prolong the life of your system.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should consult manufacturer directions and Williamsport statutes for clearance rules.

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

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

This kind of furnace draws combustion air from the surrounding space. If there’s insufficient 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 add 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 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 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, put your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the stinky odors all over your home.

You should also frequently sweep by your furnace to prevent dust from building up.
