Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough space. It also makes it hard for our professionals to accomplish furnace repair.

Regular furnace maintenance is crucial to keep your system running trouble-free. An annually serviced furnace may run more efficiently, which could reduce your heating bills.

Maintenance often helps us spot problems before they become expensive. This could help lessen future repair expenses and possibly lengthen the life of your furnace.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

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

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

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

This model of furnace pulls combustion air from the adjacent location. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could flow back into your home.

If your furnace is placed in a small room with a gas water heater, you may need to put in supplemental openings. This could include 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 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 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, situate your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors throughout your home.

You should also regularly vacuum near your furnace to block dust from building up.
