Manual Light Plug (#8 DRILL)
4-5635-1 10 MM X 1.0 VENTED IGNITER The 4-5635-1 spark plug has a 10 mm mounting thread and was designed to light Zephyr ™ style burners. This is a special "vent- ed" spark plug made from a modified R240-2465 igniter. It can be useful for rare applications where the standard igniter suffers from carbon fouling. 4055-X-ERA IGNITER FOR SEALED IGNITON WIRING The 4055-X-ERA 10 mm igniter is intended to ignite pilot tips in Class 1 Div. 2 applications. It has a 3/4"-20 threaded igniter con- nection for sealed aircraft type ignition wiring. See Bulletin 4055 and Sheet 4085 for additional information. Although the wiring method used between the ignition trans- former and the spark plug was designed and chosen to be suit- able for use in Zone 2 hazardous locations, it DOES NOT carry certifications or third party approvals.
