S8910U3000
UNIVERSAL HOT SURFACE IGNITION MODULE
Installation of this product must be performed by a trained and
qualified service technician.
APPLICATION
The S8910U Universal Hot Surface Ignition Module is
designed to provide easy field replacement for 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. The S8910U replaces existing
flame rectification type hot surface ignition modules with the
following characteristics:
• 120 Vac (up to 5A) timed warmup hot surface ignition
elements.
• Single rod (local sense) or dual rod (remote sense) hot
surface ignition.
• One or three ignition trials per call for heat.
• Four-second or seven-second ignition trials.
• Prepurge of 32 seconds or less.
• Up to 96 seconds between trial purge times (three-trial
mode only).
• Natural or LP gas.
The S8910U is not designed to replace:
• Intermittent pilot ignition controls.
• Direct spark ignition controls.
• Proven 120 Vac hot surface ignition controls.
• 24 Vac element hot surface ignition controls.
• 240 Vac input/120 Vac element hot surface ignition
controls.
• 120 Vac timed warmup hot surface ignition controls
— Ignition trial time shorter than four seconds.
— Ignition trial time longer than twelve seconds.
— Edge connectors rather than male quick-connects.
The S8910U package contains the S8910U control, and easy-
to-use instructions, and the accessories required to adapt the
existing hot surface ignition module. The accessory bag
assembly includes the White-Rodgers adapter, Robertshaw
ground lead, four 1/4 in. female .032 quick-connects, one 3/16
in. female .032 quick-connect, and nine wire labels. The
wiring labels are included to assure proper marking of the
wires attached to the existing module.
A complete list of the specific Honeywell and other modules
that the S8910U is designed to replace is provided in Tables 1
through 3.
INSTALLATION INSTRUCTIONS
NOTE: The S8910U is intended to replace only defective
ignition controls. The service technician should
make sure that the other parts of the appliance
and control system operate safely and reliably
before replacing the ignition control.
WARNING
EXPLOSION HAZARD. CAN CAUSE INJURY OR
EQUIPMENT DAMAGE.
The S8910U can only be used for direct replacement.
Check Tables 1 through 3 before replacing an existing
hot surface module with the S8910U. If the existing
module is not listed, do not use the S8910U to replace
it. Always refer to the cross-reference table for proper
DIP switch settings.
Electrical Ratings:
Control Voltage: 24 V, 60 Hz.
Maximum Valve Contact Rating: 2 A.
Current Draw: 0.4 A plus valve load.
Hot Surface Igniter Voltage: 120 Vac, 60 Hz.
Contact Rating at 120 Vac: 5 A.
IMPORTANT
The S8910U is designed for 60 Hz applications.
Timings change by 20 percent in 50 Hz applications.
Hot Surface Igniter or Igniter-Sensor:
Norton Model 201 or 271 or equivalent.
NOTE: If an igniter other than a Norton Model 201 or 271
is used, the igniter must meet the following mini-
mum specifications required over the life of the
igniter:
• Igniter must reach 1832 °F (1000 °C) within
the selected warm up time of 7, 17, 34 or
45 seconds with 102 Vac applied.
• Igniter must maintain at least 500M ohm
insulation resistance between the igniter
leadwires and the igniter mounting bracket.
• Igniter must not develop an insulating layer
on its surface (over time) that would prevent
flame sensing.
• Igniter surface area immersed in flame must
not exceed one-fourth of the grounded area
immersed in flame. This would prevent flame
sensing.
