Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is important to keep your system working trouble-free. An annually serviced furnace may run more efficiently, which could reduce your utility costs.

Maintenance often helps us discover problems before they start. This could help lower future repair expenses and potentially prolong the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or enclosing your furnace room, you should consult manufacturer specifications and Hudsonville statutes for clearance guidelines.

As a general recommendation, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service experts to comfortably work on it.

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

This type of furnace draws combustion air from the adjacent area. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is located in a small room with a gas water heater, you may need to install supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to assess airflow and ventilation as much if you have a modern, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms are often also used for 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, place your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the stinky odors throughout your home.

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