Furnace exhaust pipe hot. Unit can use room air for combustion or outside air. High efficiency furnaces fired by methane propane or butane come in many flavors with efficiencies from 80 – 97. A few reasons for an elevated temperature could be a possible blockage in the chimney dirty filters low blower speed some form of restriction in the duct. Heres how to take the temperature correctly. When this temperature starts to exceed 130 degree F it is usually an indication that there is a problem. How hot should a furnace exhaust pipe get.
Since furnace exhaust vent pipes are a prime suspect for air leaks around the chases sealing around them before insulating can great reduce infiltration and wasted heat. Warm to the touch. How hot does a furnace vent pipe get. In this regard how hot should a furnace exhaust pipe get. Conventional chimney and out the roof along with at least 20 of my.
Since the air in the furnace is way hotter than the outside air due to the combustion process it has lower pressure. Not all gases would burn off before entering the exhaust pipes if they were too far away from the furnace. A few reasons for an elevated temperature could be a possible blockage in the chimney dirty filters low blower speed some form of restriction in the duct. Should My Furnace Exhaust Pipe Be Hot. You have left out much of the information necessary.
Leaks in the vent pipe have more dire consequences that demand immediate attention. Sometimes your furnace exhaust pipe can get hot and that is normal. However these combustion gases contain residual heat that is lost through the ventilation. Methane produces 2 cubic feet of water vapor for every cubic foot of gas burned while propane produces 4 cubic feet of vapor for every cubic foot. Its also normal to see icicles or other icy build-up around the pipe during freezing weather.
