a different control is required

The Raypak 016514F Pilot Ignitor Insulator is a critical direct replacement for the legacy Raypak 064839 ignition component

preventing localized leaks and protecting the internal spring and calibration from job-site contaminants

whereas a single-pole unit only breaks one line

requirements allows for proper gas pressure regulation and prevents the equipment from operating outside its intended set point
