Well making sure that you choose the right venting style will protect them.

Gas furnace flue pipe temperature.

The different types of venting. Iii non masonary chimney without any other gas appliances connected. Will likely be above 275 degrees f. These different plastics have different maximum heat service temperatures.

Natural gas fired heating appliance with draft hood. Heat will seal the tape to the metal pipe as the temperature climbs. To make it simple the typical combustion gas temperature for a 90 efficient furnace should be in the 100 to 130 degree f range. An 80 condensing furnace flue temp.

Up to two gas appliances such as a water heater and furnace can share a properly sized flue. When this temperature starts to exceed 130 degree f it is usually an indication that there is a problem. Mid efficiency furnace has afue of 78 83 and furnace consists of forced draft non condensing medium flue stack temperature up to 300 f or 149 c and one heat exchanger. This usually equates to a median pipe material temperature value of 86 to 100 degree f.

The size would depend on your furnace s flue pipe connection. High efficiency furnace has afue of 87 97 and furnace consists of forced draft condensing low flue stack temperature up to 120 f or 49 c and at least two heat. Liquefied petroleum gas fired heating appliance with draft hood. The pipe then slips into the hole and is sealed with a high temperature silicone caulk.

This allows the hot combustion gases to to move into the chimney easier. In stock and ready to ship. Should be vented into a cat. Good up to 600 degrees f.

When applied to a cooled down pipe. Pvc has the lowest rating at 140 degrees fahrenheit cpvc has the highest at 194 degrees and abs falls in between at a maximum service temperature of 160 degrees. It is pretty important that this type of furnace is installed per manufactures instructions. Choose from our selection of flue gas temperature gauges in a wide range of styles and sizes.

Exhaust temperature o f o c chemical oxidation. Some building inspectors discourage taping up furnace clothes dryer and water heater flue joints so check your local building codes before using this tape especially when selling your home.
