So how much room should your furnace really have?
How Much Space Does My Furnace Need?
If you’re finishing your basement or sealing off your furnace room, you should consult manufacturer specifications and Franklin ordinances for clearance requirements.
As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This lets our service professionals to easily replace it.
You also need to check the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace draws combustion air from the surrounding location. If there’s not enough air, unsafe gas fumes and poisonous 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 add supplemental openings. This could involve a fully louvered door or vents in the walls.
Not sure if your furnace or water heater has adequate ventilation? We can assist you!
You don’t need to think about 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 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 clutter that could be fire hazards.
- Cleaning or laundry products
- Gasoline, paint or paint thinner
- Rags and papers
- Wood scraps and sawdust
- Used filters
