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 shut down if it doesn’t have enough clearance. It also makes it challenging for our technicians to complete furnace repair.

Annual furnace maintenance is essential to keep your system working smoothly. An annually serviced furnace may work more efficiently, which could reduce your heating costs.

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

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 take a look at manufacturer instructions and Brighton ordinances for clearance guidelines.

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

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

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

If your furnace is located in a little room with a gas water heater, you may need to install extra 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 up-to-date, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double 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, put your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the stinky odors around your home.

You should also routinely sweep by your furnace to prevent dust from building up.
