Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough room. It also makes it difficult for our specialists to perform furnace repair.

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

Maintenance often helps us discover troubles before they begin. This could help lessen future repair expenses and likely extend the life of your system.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should take a look at manufacturer specifications and Carlsbad statutes for clearance rules.

As a general recommendation, your heater should be 30 inches away from furnace room walls on all sides. This allows our service professionals to comfortably work on it.

You also need to make sure the area has enough airflow and ventilation, especially if you have an aging furnace with a metal flue.

This model of furnace needs combustion air from the surrounding area. If there’s insufficient air, hazardous gas fumes and deadly carbon monoxide could leak into your home.

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

You don’t need to consider 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 function 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 create wear on your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also regularly vacuum around your furnace to stop dust from developing.
