Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough space. It also makes it hard for our specialists to complete furnace repair.

Routine furnace maintenance is crucial to keep your unit running trouble-free. A routinely serviced furnace may run more efficiently, which could decrease your heating expenses.

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

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should take a look at manufacturer specifications and Rochester statutes 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 technicians to conveniently work on it.

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

This kind of furnace pulls combustion air from the surrounding area. If there’s insufficient air, dangerous gas fumes and poisonous carbon monoxide could back draft 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 modern, 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 clutter 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 create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors throughout your home.

You should also routinely sweep near your furnace to prevent dust from building up.
