If you’re updating your basement or sealing off your furnace room, you should consult manufacturer directions and Beaverton statutes for clearance rules.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This lets our service professionals to conveniently repair it.

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

This kind of furnace needs combustion air from the nearby location. If there’s insufficient air, hazardous gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to put in more openings. This could consist of 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 function as laundry and storage space, you should keep yours free of things 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 in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors all over your home.

You should also regularly sweep around your furnace to prevent dust from building up.
