Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough space. It also makes it difficult for our specialists to complete furnace repair.

Annual furnace maintenance is crucial to keep your equipment working trouble-free. A routinely serviced furnace may work more efficiently, which could decrease your energy expenses.

Maintenance often helps us spot issues before they become expensive. This could help lessen future repair expenses and likely 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 finishing your basement or enclosing your furnace room, you should research manufacturer directions and Kearney ordinances for clearance guidelines.

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

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

This model of furnace pulls combustion air from the adjacent space. If there’s inadequate air, hazardous gas fumes and toxic 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 consist of 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 system uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms are often also used for 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, situate your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors all over your home.

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