15.6 Lift the inspection port cover on the front of the combustion chamber to observe the
flame. “Wear adequate face and eye protection”. The flame tips should extend
3/4 of the way into the combustion chamber. When the unit is adjusted properly the
ash inside the chamber will be white to off white.
Flame tips touching the target brick (end of the chamber) will cause combustion
chamber damage. This condition may be caused by a worn nozzle, or excess
burner fuel pressure. When this condition exists, the ash in the chamber will be
brown to black.
