Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is important to keep your system running smoothly. An annually serviced furnace may work more efficiently, which could reduce your energy bills.

Maintenance often helps us discover issues before they become expensive. This could help reduce future repair costs and possibly prolong the life of your unit.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or closing off your furnace room, you should consult manufacturer specifications and Booneville ordinances for clearance guidelines.

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

You also need to check the room has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

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

If your furnace is located in a tiny room with a gas water heater, you may need to install supplemental 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 pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as 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 somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the smelly odors around your home.

You should also routinely vacuum near your furnace to stop dust from accumulating.
