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 get too hot if it doesn’t have enough clearance. It also makes it hard for our professionals to perform furnace repair.

Routine furnace maintenance is important to keep your unit working smoothly. A routinely serviced furnace may work more efficiently, which could lower your energy expenses.

Maintenance often helps us notice issues before they start. This could help reduce future repair expenses and possibly lengthen the life of your unit.

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should research manufacturer directions and Carson City statutes for clearance guidelines.

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

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

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

If your furnace is positioned in a small room with a gas water heater, you may need to add more openings. This could consist of 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 unit uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of things 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 corrode your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors around your home.

You should also frequently sweep near your furnace to block dust from accumulating.
