Summary
Offset smokers naturally create temperature variations due to their design—the cooking chamber closest to the firebox runs hotter, while the far end cools. The split-fire technique addresses this by dividing the coal bed into two zones within the firebox, using air intake adjustment and fuel placement to balance heat delivery. This guide walks through settin
Why Offset Smokers Create Hot Spots
Offset smokers are designed with the heat source (firebox) attached to one side of the main cooking chamber. Heat enters through an opening at the chamber's base and exits through a chimney at the far end. This linear path creates a natural temperature gradien

Understanding the Split-Fire Approach
The split-fire technique divides your coal bed into a primary zone (closer to the intake opening) and a secondary zone (positioned toward the back of the firebox). The primary zone receives fresh air from the intake damper and generates the majority of heat. T

Setting Up the Fuel Bed
Start with a clean firebox and a grate that allows ash to fall below. Lay down a thin base of ash or sand (about 1 inch) to protect the firebox floor. Build your primary coal bed on the side of the grate closest to the intake damper. Aim for a bed roughly 4–6

Air Intake Tuning
Most offset smokers have one or two air intake dampers on or near the firebox door, and a chimney damper at the far end of the chamber. For split-fire operation, start with the firebox intake damper about one-quarter open. This modest opening gives the primary
