[. . . ] Do not bypass any of these safety interlocks. This will result in unsafe conditions. Process air flow Series LV AIRFLO® burners draw the required oxygen for combustion from the available process air flow across the burner. A correct fresh air flow across the burner is essential for safe operation of the burner, and should be safeguarded by a safety interlock (pressure switch or flow switch) as described in the applicable local codes or regulations. Refer to "Specifications" on page 4-21. 4-7 for more details or contact MAXON if you require further support. Pilot ignition Adjust pilot gas regulator to correct set point before pilot ignition attempt. [. . . ]
