So how much area should your system really have?
How Much Space Will a Furnace Take Up?
If you’re updating your basement or enclosing your furnace room, you should consult manufacturer instructions and Marshalltown ordinances for clearance requirements.
As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This lets our service technicians to conveniently replace it.
You also need to ensure the area has enough airflow and ventilation, especially if you have an aging furnace with a metal flue.

This type of furnace pulls combustion air from the nearby area. If there’s inadequate air, unsafe gas fumes and poisonous carbon monoxide could leak into your home.
If your furnace is located in a tiny room with a gas water heater, you may need to add supplemental openings. This could include 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 draw in air.
Keep Hazardous Items Separate from Your Furnace
Although furnace rooms double as laundry and storage space, you should keep yours free of items that could be fire hazards.
- Cleaning or laundry products
- Gasoline, paint or paint thinner
- Rags and papers
- Wood scraps and sawdust
- Used filters
If you have a cat, situate your litter box in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors all over your home.
You should also routinely clean around your furnace to block dust from developing.
