Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is important to keep your equipment operating well. A routinely serviced furnace may run more efficiently, which could lower your utility expenses.

Maintenance often helps us notice issues before they become expensive. This could help reduce future repair costs and likely extend the life of your unit.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should take a look at manufacturer instructions and Bishop laws for clearance requirements.

As a general recommendation, your heater should be 30 inches away from furnace room walls on all sides. This permits our service experts to easily replace it.

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

This model of furnace pulls combustion air from the adjacent space. If there’s insufficient air, dangerous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is located in a little room with a gas water heater, you may need to add 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 newer, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to add 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 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, place your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the stinky odors around your home.

You should also frequently vacuum by your furnace to block dust from building up.
