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

Your furnace can shut down if it doesn’t have enough space. It also makes it challenging for our professionals to perform furnace repair.

Annual furnace maintenance is important to keep your equipment working smoothly. A routinely serviced furnace may work more efficiently, which could decrease your energy expenses.

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

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

As a general rule of thumb, your system should be 30 inches away from furnace room walls on all sides. This lets our service technicians to conveniently replace it.

You also need to make sure the space has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace needs combustion air from the nearby space. If there’s insufficient 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 extra 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 modern, high-efficiency furnace with PVC piping. Your system 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 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, put 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 clean by your furnace to stop dust from building up.
