Preheat your pellet grill like you normally would, setting it to your desired temperature.
Place one fire starter cube in the bottom of a loaf pan..
Light the fire starter with a wand lighter and allow it to ignite fully.
Add three charcoal briquettes inside the smoker box. Make sure the stand is installed on the bottom of the box.
Place the smoker box in the loaf pan on top of the lit fire starter. Allow the charcoal to ignite.
Using long handed tongs, flip the charcoal briquettes over to ignite the other side of each.
Add the wood chunks on top of the lit charcoal. Arrange the pieces so that the lid will fit on top of the box. Allow the wood to start smoldering.
Wearing heatproof gloves, carefully place the lid on top of the smoking wood.
If cooking on the bottom grates without the top rack installed, place the loaf pan containing the lit smoker box on the grates of the grill, preferable toward the back left side but away from the grill temperature probe.
If cooking on the top rack, remove the stand from the firebox and place it directly on the grill grates toward the back left side, not too close to the grill temperature probe.
Add your food to the smoker and cook according to your recipe.
