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).
Application: Provide electronic control of direct hot surface ignition
systems used on gas fired furnaces, boilers, and other heating
appliances.
Dimensions, Approximate: 5 1/4 in. high x 4 1/16 in. wide x 1 15/16 in.
long (133 mm high x 103 mm wide x 49 mm deep)
Type of Gas: Natural or LP
Electrical Ratings: 24 Vac
Frequency: 60 Hz
Flame Failure Response Time (sec): 1.5 sec.
Ignition Sequence: The number of trials for ignition and trial time is
determined by the selection tab. If a selection tab is not installed, the
module will operate at four seconds trial time and one ignition trial.
Ignition Source: Line Voltage (120 VAC) Hot Surface Element (Norton
Model 201 or 270)
Ignition System Type: Direct Hot Surface Ignition
Maximum Valve Load @ 24 Vac (Amps): 2A
Typical Gas Control: VR8205, VR8305
Typical Ignition Hardware: Norton 201, Norton 271, Q354
Maximum Ambient Temperature: -40 F to +175 F (-40 C to +79 C)
Approvals:
Canadian Standards Association: Design Certified
Y8610U Universal Retrofit Intermittent Pilot Gas Burner Ignition
Systems
Complete kits converting conventional standing pilot system to
intermittent pilot system. For use with 24 Vac gas-fired
atmospheric furnaces, boiler and heating appliances.
• Y8610U kits are for use with natural or LP gas: provides 100 percent
pilot gas shutoff if pilot fails to light; after 6-minute delay, trial for
ignition is repeated.
• Ignition trail/delay sequence is repeated until the appliance lights or
call for heat is removed.
Application: Provide electronic control of intermittent pilot ignition
systems used on gas fired furnaces, boilers, and other heating
appliances.
Dimensions, Approximate: 3 15/16 in. high x 5 7/16 in. wide x 2 5/8 in.
