What is a furnace exhaust pipe?

The furnace exhaust flue, also called a furnace exhaust stack, is a metal tube that vents the noxious combustion gases from the heat exchanger to the outside. Inside the stack resides a damper that regulates the pressure between the air from the furnace and the outside air.

How do I vent my furnace to the roof?

Furnaces can shut off entirely because these vents are blocked with snow or ice – this is simply a safety mechanism. Without the proper ventilation, carbon monoxide can build up inside your home. The blockage of your vents will also decrease your energy efficiency.

Can mice enter through furnace exhaust?

Gaps, cracks, and larger disconnections in the duct system create points of access for pests to enter your HVAC system as well as your home or building's interiors. Insects, mice, and larger vermin may enter the duct system, depending on the size of air leaks.

How do you tell if your furnace is venting properly?

How Do I Know If My Furnace Isn't Venting Properly? Gas furnace fumes are moist, so if you notice “sweat” on your windows, this is a sign that your furnace isn't venting correctly. When your furnace comes on in the morning, if it is venting into your house rather than outdoors, moisture will condense on the cold glass.

Should there be water in furnace exhaust pipe?

A standard-efficiency furnace extracts some heat from the combustion gases and quickly vents them out the exhaust or flue pipe. So there should be no water involved with a standard-efficiency furnace. If there is a condensation leak, the exhaust or flue pipe may be incorrectly sized.

Why do I have water in my furnace exhaust pipe?

When a high efficiency furnace releases the exhaust gases, condensation is created. This condensation is a significant amount of moisture on the PVC pipe, and it needs to be drained either into a floor drain or a condensation pump. A water leakage occurs when the condensation is unable to drain properly.

Do all roof vents need a cap?

Most roof vent pipes are a part of a plumbing system and are connected to water systems that are wet all the time. In this regard, it's not necessary to install a roof vent cap to prevent rain from getting in the vent pipe.

Can you vent a furnace without a chimney?

Direct-venting or side wall vent chimney and flue systems are a method of venting the exhaust gases from a heating appliance directly out through the side wall of a building while eliminating the need for a vertical chimney of any sort.

What is a roof vent cap?

As part of any roof ventilation system, a roof vent cap can help provide an escape for hot air. This escape of hot air also pulls cooler air inside, without the need for using a roof fan. Roof vent covers work at keeping moisture, rain, and insects out.

How do I know if my furnace flue is clogged?

Yellow Flame Normally, the flame is blue, and a change in the color from blue to yellow indicates a clogged furnace flue. The furnace flue vents out carbon monoxide, but when it has a blockage, carbon monoxide remains inside the furnace. Combustion of carbon monoxide produces a yellow flame.

How do I know if my flue pipe is clogged?

How to inspect your flue pipe

1. Remove the flue cap to check for blockages such as debris or birds' nests.
2. Replace and secure the cap tightly to the end of the flue pipe.
3. Look for signs of blockages by examining the pipe itself – water streaks or rust on the flue pipe may indicate a blockage, causing moisture to back up.

How do you clear a clogged furnace exhaust?

Scrub the inside free of any dust and debris; then use the handheld vacuum to get out as much as you can. Wipe it clear with a rag or soft cloth and then replace the cap. Cut away any branches or remove any object that might be obstructing the pipe and creating debris. The vent should always be clear.
