Honeywell S8910 Universal Hot Surface Ignition Module
Universal Hot Surface Ignition Module is designed to provide easy field replacement of a wide range of hot surface ignition modules manufactured by Honeywell, Robertshaw and White-Rodgers. The S8910U Module provides operating control of a direct ignition system using a 120 Vac hot surface igniter.
• Replaces many White-Rodgers, Robertshaw and Honeywell hot surface ignition models.
• For 120 Vac (up to 5.0A) surface igniter (Norton 201/271 or equivalent).
• For local (single rod) or remote (dual rod) rectification type flame sensing.
• Contains easy-to-use instructions plus the accessories required to adapt the existing hot surface ignition module.
• Provides one or three ignition trials (four-second or seven-second trials) per call for heat; prepurge of 32 seconds or less; up to 96 seconds between purge trial times.
• Temperature range is -40 to +175 F (-40 to +79 C).
