Gas Furnace Flue Pipe Temperature

These different plastics have different maximum heat service temperatures.

Gas furnace flue pipe temperature. 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. Well making sure that you choose the right venting style will protect them. When we are talking about gas furnace vent pipe code we need to talk about the different types of the vents first after all you want to keep your family safe from harm. You would core a hole 1 4 to 1 2 inch bigger than the outer diameter of the pipe.

Natural gas fired heating appliance with draft hood. Good up to 600 degrees f. To make it simple the typical combustion gas temperature for a 90 efficient furnace should be in the 100 to 130 degree f range. The pipe then slips into the hole and is sealed with a high temperature silicone caulk.

If the furnace is a forced draft model the water heater must connect above higher and closer to the vertical flue pipe in an approved manner so that flue gasses go up the stack and not out the water heater draft hood. Gas fired heating appliance no draft. In stock and ready to ship. 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. Choose from our selection of flue gas temperature gauges in a wide range of styles and sizes. 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. Iii non masonary chimney without any other gas appliances connected.

Up to two gas appliances such as a water heater and furnace can share a properly sized flue. Pitch the flue pipe up toward the chimney. Exhaust temperature o f o c chemical oxidation. This allows the hot combustion gases to to move into the chimney easier.

An 80 condensing furnace flue temp. It is pretty important that this type of furnace is installed per manufactures instructions. 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. Will likely be above 275 degrees f.

Should be vented into a cat. The different types of venting. When this temperature starts to exceed 130 degree f it is usually an indication that there is a problem. Heat will seal the tape to the metal pipe as the temperature climbs.
