with separate flame sense and spark probes
NOTE: Max length of spark cable should be less than 3ft (0.9m) and rated at 15kV. The cable must not run in
continuous contact with any metal surface or spark voltage is greatly reduced. Use ceramic or plastic standoff
insulators as required. Ensure burner is grounded directly to module for spark return path.
INSTALL PROGRAM KEY
The control replaces all listed models with the following features:
• direct spark ignition
• remote rod flame sense or direct flame sense through ignitor
• one or three ignition tries
• four to eleven second trial for ignition time
• pre-purge options zero or 30 seconds
Eight program keys are provided for different applications. Timings and Retries for each program key are shown in the Speci-
fications section on page 2 of this installation manual. Choose the proper program key for the application. Install the selected
program key in the slot on the left side of the module (see figure 1) and fit the timing label on the cover.
If the module you are replacing is not listed in the table contact the manufacturer of the appliance for a recommended replace-
ment or retrofit.
After inserting the proper program key, dispose of the remaining keys to ensure the correct key remains in the module.
If control fails to operate see troubleshooting guide for remedy.
