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 room. It also makes it difficult for our specialists to complete furnace repair.

Annual furnace maintenance is essential to keep your system running trouble-free. An annually serviced furnace may work more efficiently, which could decrease your heating expenses.

Maintenance often helps us discover issues before they begin. This could help lower future repair costs and possibly extend the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should take a look at manufacturer instructions and Rapid City laws for clearance guidelines.

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

You also need to make sure the room has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace pulls combustion air from the adjacent space. If there’s insufficient air, unsafe gas fumes and deadly carbon monoxide could flow back 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 include a fully louvered door or vents in the walls.

You don’t need to assess 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 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 somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors all over your home.

You should also regularly sweep near your furnace to prevent dust from developing.
