Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to run correctly.

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

Annual furnace maintenance is essential to keep your equipment running well. A routinely serviced furnace may heat more efficiently, which could reduce your energy expenses.

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

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should take a look at manufacturer specifications and Northglenn ordinances for clearance guidelines.

As a general suggestion, your system 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, hazardous 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 assess 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 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, situate 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 all over your home.

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