Do not bend or twist the fire-trace tube or bind the tube using cable ties. Otherwise, the fire
cylinder may fail.
1. Cut off the end of the fire-trace tube evenly.
Ensure that the wall thickness at the end of the fire-trace tube is consistent.
Ensure that the fire-trace tube, threaded nozzle, and end adapter are clean and free of dust.

2. Remove the connection nut and riser screw thread from the top of the fire cylinder, and
route the nut and riser screw thread through the fire-trace tube.

3. Clamp the end of the fire-trace tube to the threaded nozzle using a pipe holder.
Hold the pipe holder close to the end to avoid bending the tube during pipe insertion.
