Installation and Set Up

Installation of the S8910U

• Mount the module
• Do not mount with terminals facing up
• protect the module from exposure to water,
  moisture, corrosive chemicals and excessive dust
  and grease.
• Install selection tab (personality plug-ins)
• The number of trials for ignition and trial time
  is determined by the selection tabs.
• Four selection tabs are included with the S8910U.
  (A,B,C,D)
• Without a selection tab, the module operates at
  four-second trial time and one ignition.
• Selection tabs A and B 4 seconds.
• Selection tabs C and D 7 seconds.
• Wire the module
• Use diagrams in installation instructions for
  wiring

11
Selection Tab Installation

• See Tables 1 through 3 in installation
  instructions (Form 68-1061) for correct tab
  selection.
• Select and Install the correct tab, push firmly
  in place and discard the remaining tabs.

Troubleshooting of the S8910U

• LED shows system status for the current call for
  heat
• Pulsing heartbeat is the normal operating mode
  during a call for heat (24V terminal is powered).
  The system can be in any of the normal operating
  modes including prepurge, warm-up, ignition
  trial, between trial purge, or normal run.
• One flash indicates the S8910U is in an ignition
  lockout mode. The most probable cause is the main
  burner failing to light or failure to detect the
  flame. Run the appliance through a call for heat
  and if the burner does not light, check the
• gas supply
• input voltage
• hot surface igniter
• gas control
• Wiring
• If the main burner lights, but goes out at the
  end of ignition trial, check the
• igniter/sensor
• flame rod
• burner ground connections
• wiring

17
Troubleshooting of the S8910U

• LED Continued
• Two flashes indicates the flame rectification
  signal is weak. The most probable causes are
• contaminated or mis-located igniter/sensor or
  flame rod
• poor flame sense lead-wire insulation or
  connections
• poor gas pressure
• If the flame rectification signal is strong when
  the appliance lights, but weak while heat is
  being delivered, check for overheating of the
  igniter/sensor, flame rod ceramic or flame sense
  leadwires.
• Three flashes indicate an internal error. The
  most probable cause is an S8910U logic failure.
  Start a new call for heat and if the three-flash
  signal returns, replace the S8910U.

The S8910U Advantage

• When promoting the S8910U keep these advantages
  in mind
• The S8910U replaces over 100 Honeywell and
  competitors ignition modules reduces inventory
  by stocking one versus many and saves time and
  money looking for the right part.
• Easy to use instructions and adaptation
  accessories saves the contractor valuable time
  and resources.
• Personality Plug-Ins - match the ignition
  sequence of the model being replaced using the
  plug in selector tabs for a true Universal
  replacement.
• The S8910 is application flexible and can be used
  with single rod or dual rod systems, and natural
  or LP gas.
• The diagnostic LED makes troubleshooting simple,
  identifying ignition lockout, flame rectification
  signal and control failure, solving the problem
  quickly and satisfying the customer.
