Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to work correctly.

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

Regular furnace maintenance is important to keep your unit running smoothly. A regularly serviced furnace may heat more efficiently, which could reduce your heating expenses.

Maintenance often helps us discover issues before they begin. This could help lessen future repair expenses and possibly extend the life of your unit.

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer instructions and Manassas statutes for clearance rules.

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

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

This model of furnace draws combustion air from the adjacent location. If there’s insufficient air, hazardous gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is placed in a small room with a gas water heater, you may need to install extra 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 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, 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 move the smelly odors around your home.

You should also frequently clean by your furnace to prevent dust from building up.
