Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work properly.

Your furnace can shut down if it doesn’t have enough room. It also makes it difficult for our technicians to perform furnace repair.

Regular furnace maintenance is essential to keep your equipment working smoothly. An annually serviced furnace may heat more efficiently, which could lower your utility bills.

Maintenance often helps us notice troubles before they start. This could help reduce future repair expenses and potentially lengthen the life of your unit.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer directions and Hickory ordinances for clearance requirements.

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

You also need to ensure the room has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace draws combustion air from the adjacent space. If there’s insufficient air, dangerous gas fumes and poisonous carbon monoxide could flow back into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to install 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 up-to-date, 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 double as laundry and storage space, you should keep yours free of items 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, situate your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors around your home.

You should also routinely vacuum around your furnace to block dust from accumulating.
