Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is important to keep your unit running trouble-free. An annually serviced furnace may heat more efficiently, which could lower your heating costs.

Maintenance often helps us spot troubles before they start. This could help reduce future repair costs and possibly prolong the life of your system.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should take a look at manufacturer specifications and Wisconsin Rapids statutes for clearance rules.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This allows our service technicians to conveniently repair it.

You also need to check the room has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace pulls combustion air from the nearby space. If there’s insufficient air, dangerous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is located in a little room with a gas water heater, you may need to install more openings. This could include a fully louvered door or vents in the walls.

You don’t need to consider 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 function as laundry and storage space, you should keep yours free of clutter 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 in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors around your home.

You should also regularly clean by your furnace to stop dust from accumulating.
