Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough clearance. It also makes it challenging for our specialists to complete furnace repair.

Annual furnace maintenance is crucial to keep your equipment operating smoothly. A regularly serviced furnace may work more efficiently, which could decrease your energy expenses.

Maintenance often helps us notice problems before they become expensive. This could help reduce future repair bills and likely lengthen the life of your system.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should research manufacturer instructions and Erie laws for clearance requirements.

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

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

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

If your furnace is positioned in a little room with a gas water heater, you may need to install extra openings. This could include 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 modern, 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, situate your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors all over your home.

You should also regularly clean by your furnace to block dust from accumulating.
