Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is crucial to keep your system working trouble-free. A regularly serviced furnace may run more efficiently, which could decrease your energy expenses.

Maintenance often helps us notice issues before they become expensive. This could help lessen future repair costs and likely lengthen the life of your furnace.

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should research manufacturer specifications and Manassas Park ordinances for clearance guidelines.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service technicians to easily replace it.

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

This kind of furnace needs combustion air from the surrounding area. If there’s not enough air, dangerous gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to put in extra openings. This could consist of 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 draw 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, put your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors all over your home.

You should also routinely clean around your furnace to stop dust from building up.
