The normal cause is thought to be “over insertion” of the tube into the combustion area (insertion beyond the 1/4" recom- mended recess in the tube entry tunnel). This may or may not be the cause. The following are additional conditions that need be considered when tube burn-off is experienced.

scale. The restriction causes back pressure in the combus- entry tunnel. This causes metal fatigue and inevitable tube burn-off.
levels produce higher flame temperatures and higher com- bustion area temperatures. Flame temperatures @ 14% CO2 Failure of the combustion refractory will eventually lead to tube burn-off and/or heat exchanger failure.
which maintains oil temperature between 120 to 130° during burner off cycle regardless of stored oil temperature or duration of off cycle.
self-regulating heating element to maintain constant temperature. The burner always starts with pre-heated oil, assuring improved atomization, ignition, combustion and fuel efficiency. Fits Beckett and most other burners with same size nozzle line. 120v AC.
