Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough clearance. It also makes it challenging for our specialists to accomplish furnace repair.

Regular furnace maintenance is essential to keep your unit operating smoothly. A routinely serviced furnace may heat more efficiently, which could decrease your heating expenses.

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

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should research manufacturer directions and Wharton ordinances for clearance rules.

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

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

This type of furnace pulls combustion air from the surrounding location. If there’s not enough air, unsafe gas fumes and deadly carbon monoxide could flow back into your home.

If your furnace is placed in a little room with a gas water heater, you may need to put in supplemental 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 furnace 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 somewhere else. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also frequently vacuum around your furnace to block dust from accumulating.
