[General] - Why do we ask installers to call us regarding the insertion depth of the blast tube on commercial burners?
Two Reasons we ask this:
- All burners are range rated, capable of firing a range of outputs. This makes a difference to the flame lengths of the burner. If the burner is not set at the correct depth, the flame could be hitting the back of the boiler causing damage in the long run.
- Different boiler designs need the burner blast tube inserted at different depths to allow them to function properly.
