![]() ![]() The greater the gap, the greater will be the hot flue gases flow across the chimney. The greater the height of the chimney, the greater will be the gap between the chimney pipe and the end cap. This gap is responsible for maintaining a certain pressure difference between the grill chamber and the atmospheric pressure. Usually, there is a gap provided between the tip of the chimney pipe and the bottom of the chimney cap. This is especially required for burning large pit of pellets in case of large size grills and their respective chambers. This phenomenon of continuous entry of ambient air inside the grill chamber is essential for the combustion of fuel, since the larger the amount of airflow inside the chamber, the greater will be the presence of oxygen for combustion. ![]() ![]() This cycle of hot flue gases exiting the chimney and relatively cold ambient air entry into the grill chamber keeps on happening continuously until there are pellets to create a high-pressure area. While the hot flue gases traverse the chimney, it expands and creates a region of low pressure which subsequently gets filled by the relatively higher ambient pressure at the grill chamber’s inlet side. Similarly, the hot air in the grill chamber rises from a higher-pressure region towards the low atmospheric pressure region at the top of the chimney. The working of a grill chimney is based on the convection principle.īut did you know, what convection really is?Ĭonvection is a process in which the hot air or fumes with less density flow from a region of high pressure to a region of relatively cold air with low pressure until the equilibrium pressure is created. Most of you might have seen the chimney used in various places such as factories, hose roofs, etc. There is a science of thermodynamics that works in a pellet grill chimney. Science Behind the Working of Pellet Grill Chimneyīefore going to know about chimney adjustment, you should learn about the science behind the working of pellet grill chimney. Keep reading to know more about chimney adjustment in detail. ![]() In the winter and windy weather, the gap between the chimney pipe and the chimney cap should be approximately ½”. The height of the chimney cap should be adjusted differently for summer and winter.Īs per the Camp Chef, the gap of a chimney cap should be approximately 1’’- 1 ½’’ in summer. You should adjust the distance recommended by the instruction manual of a Camp Chef pellet grill. Too much raising or lowering the chimney cap on your Camp Chef grill can lead to a negative impact on grill performance. Lowering the chimney cap can hinder the airflow and affect the grill performance due to inefficient combustion.Ĭhimney cap adjustment should be perfect for efficient cooking. So, what’s the purpose of chimney adjustment on your Camp Chef?Ĭhimney cap adjustment on a camp chef pellet grill allows you to direct and remove the excess smoke out of your grill. It’s a chimney cap adjustment of your grill. However, you may encounter issues such as temperature fluctuation, incomplete combustion, etc.īut did you know, what’s the reason behind it?
