Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is essential to keep your equipment working smoothly. A routinely serviced furnace may work more efficiently, which could reduce your utility bills.

Maintenance often helps us spot problems before they begin. This could help lessen future repair costs and possibly prolong the life of your furnace.

So how much clearance 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 directions and Saint Charles laws for clearance requirements.

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

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

This kind of furnace draws combustion air from the adjacent space. If there’s not enough air, dangerous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is positioned in a tiny 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 think about airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of clutter 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 in another room. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors throughout your home.

You should also frequently clean around your furnace to block dust from building up.
