Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work properly.

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

Regular furnace maintenance is crucial to keep your unit working smoothly. An annually serviced furnace may heat more efficiently, which could decrease your utility bills.

Maintenance often helps us notice troubles before they start. This could help reduce future repair bills 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 consult manufacturer directions and Hickory ordinances for clearance rules.

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You also need to ensure the room has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This model of furnace draws combustion air from the nearby space. If there’s inadequate air, dangerous gas fumes and toxic carbon monoxide could back draft into your home.

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

You don’t need to consider airflow and ventilation as much if you have a up-to-date, 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 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 in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors throughout your home.

You should also routinely vacuum around your furnace to block dust from building up.
