So how much clearance should your furnace really have?
How Much Space Will a Furnace Take Up?
If you’re finishing your basement or enclosing your furnace room, you should take a look at manufacturer instructions and Corpus Christi laws for clearance guidelines.
As a general suggestion, your heater should be 30 inches away from furnace room walls on all sides. This lets our service experts to comfortably repair it.
You also need to check the room has enough 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, hazardous gas fumes and deadly 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 install 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 add air.
Keep Flammable Items 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 somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the smelly odors throughout your home.
You should also regularly vacuum around your furnace to block dust from developing.
