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 overheat if it doesn’t have enough clearance. It also makes it challenging for our professionals to complete furnace repair.

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

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

So how much room should your system 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 directions and Derby laws for clearance requirements.

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

You also need to make sure the space has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace draws combustion air from the nearby location. If there’s inadequate air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a small room with a gas water heater, you may need to install extra 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 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, situate your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the smelly odors throughout your home.

You should also regularly clean around your furnace to block dust from developing.
