Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to work correctly.

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

Annual furnace maintenance is important to keep your system working smoothly. A regularly serviced furnace may heat more efficiently, which could reduce your utility expenses.

Maintenance often helps us discover troubles before they start. This could help reduce future repair costs and potentially extend the life of your unit.

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer instructions and Florissant laws for clearance rules.

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

You also need to ensure the area has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace needs combustion air from the nearby location. If there’s not enough air, hazardous gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is located in a small room with a gas water heater, you may need to put in supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to assess 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 double 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, put your litter box in another room. 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 routinely clean around your furnace to prevent dust from accumulating.
