  • A pellet grill without having a smokestack uses less fuel because the produced smoke fails to escape through the open-air vents. For that reason, users have to fill out the fuel again and again.
  • Smokestacks have enough adjustable gaps that let you control the amount of smoke venting out.
  • Users of pellet grills with smokestacks not only get control of the smoke production but also can control the temperature as well. Smokestack assists in making the temperature more evenly.
  • Apart from all those, a smokestack can easily keep the water and debris out of the pellet grill.
  • In the winter season, you get the best benefit from this when there are icy winds and snow in the surrounding. It helps to reduce the heat from flaring up in this weather.
  • Also, it reduces the chance of filling the messy smoke in the backyard.

When To Use Smoke Stack On Traeger?

Many of the grill users have a query on when they will use or adjust the smokestack on Traeger. Though the smokestack has a crucial benefit to the pellet grill system, it is not needed to use on a regular basis.

Specifically, it is most needed in the winter season when you desire to cook in cold, windy weather.

If your grill venting system is opened, it will seem so harder for the grill to maintain the temperature that you set it to. For this, it extends the cooking time, which falls a great impact on the amount of fuel.

But if your grill has a featured smokestack, it will easily mitigate the extreme wind weather entering the grill. By this, the temperature that you set will be under control. In short, must use a smokestack on your Traeger while cooking in the weather’s colder temperatures.

How To Adjust Smoke Stack On Traeger

Now it is essential to learn about how to adjust the smokestack on the Traeger. When installing or assembling the grill, you will have to adjust the smokestack. Here we have included all the needed steps to adjust the smokestack on Traeger:

  • First, you have to ensure that the smokestack is adequately vented. For that, either you have to increase the height of the stack or may need to open the stack cap at a maximum level. 
  • To increase the height of the smokestack, turn it counterclockwise and adjust it to your preference.
  • Also, adjust the stack cover or cap by turning it to the right or clockwise. Ensure it has 1-2 inches high from the bottom of the cap.
  • Don’t ignore the positioning of the smokestack as well. It must be at the center of the cooking chamber. This is for the smoke will be evenly distributed to the chamber.
  • But if you are using good quality hardwood pellet with approximately 31,800 Btu, you will need to install two smokestacks. Otherwise, the smoke will not escape properly.  

Should Traeger Smoke Stack Be Opened Or Closed?

If the fact is about opening and closing for Traeger Smokestack, it should always be open as the expert suggestions. Closing the stack cap or decreasing the gap, it will affect the amount of smoke being generated by the Traeger.

When we lower the gap or close the stack, it will first restrict the airflow. For lack of proper airflow, the grill will produce less heat. 

Also, while cooking in cold and windy weather, the temperature will start fluctuating. By this, the set temperature can’t be controlled.

There will build a high amount of gases in the grill without appropriate venting, which increases the risk of explosion. So, obviously, you should never close the stack cap completely. There should be at least between 1 to 2 inches difference in the cap. 

Cleaning Of Traeger Smoke Stack

To keep the efficiency of the smokestack, it is a must to clean it periodically. After prolong using the grill, there will surely build up ash, carbon, and grease over the smoke stack wall and cap.

You have to clean out the smokestack at least the difference of 6 months. Here are the needed steps to clean the Traeger smokestack:

  • First, make sure that the grill is turned off and unplugged.
  • Make sure that the grill is completely cool to the touch.
  • Now disconnect the smoke stack’s cover and inspect the interior to clean it with ease. You will find a lot of black soot on it.
  • Clean out those using a wire brush.
  • Then, take a damp cloth and wipe down the stains of soot and ash from the cap of the smokestack on a pellet grill.
  • Avoid water while cleaning the interiors as it causes the grill to rust.
  • Once the cleaning is done, reassemble the cover of the smokestack.


What does the chimney cap do on a Traeger?

The main purpose of a chimney cap adjustment is to allow direct access or remove the smoke. It will keep the rain out as well. But here a proper cap adjustment is needed. Otherwise, it will restrict the airflow. 

How do I adjust the smokestack on a pellet grill?

First, adjust the smokestack by turning it counterclockwise. Then adjust the cap by twisting it clockwise. But there should have at least a 1-2 inch gap to ensure fluent air flowing. 

How tall should a smokestack be on a pellet grill?

The length of the smokestack depends on the size of your pellet grill to ensure maximum heat output of the firebox. For example, if the grill chamber is 500 to 600 square inches, the smokestack should be 3-4 inches to 14 inches(including the cap) in diameter.
