Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to run properly.

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

Annual furnace maintenance is essential to keep your unit running trouble-free. A routinely serviced furnace may heat more efficiently, which could reduce your energy costs.

Maintenance often helps us notice problems before they become expensive. This could help lessen future repair expenses and likely lengthen the life of your unit.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should research manufacturer specifications and Northglenn ordinances for clearance guidelines.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This permits our service experts to conveniently work on it.

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

This kind of furnace draws combustion air from the surrounding location. If there’s not enough air, unsafe gas fumes and toxic carbon monoxide could back draft into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to put in more 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 unit 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 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 in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

You should also frequently vacuum near your furnace to stop dust from developing.
