Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is essential to keep your unit running trouble-free. A routinely serviced furnace may heat more efficiently, which could reduce your utility expenses.

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

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should consult manufacturer specifications and Moline laws for clearance rules.

As a general suggestion, your heater should be 30 inches away from furnace room walls on all sides. This lets our service technicians to conveniently work on it.

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

This kind of furnace needs combustion air from the surrounding area. If there’s insufficient air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to install more openings. This could involve 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 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 are often also used for 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, put 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 throughout your home.

You should also regularly sweep by your furnace to stop dust from developing.
