Replacement for JCI G891 Pulse Ignition Control
The BASO BGN891 (black) Ignition Control is a direct replacement for Natural Gas or Propane ovens which have
a Johnson Controls G891 (blue) Pulse Ignition Control.
Replacement Instructions:
1. Disconnect the electrical power from the appliance before performing service.
2. Remove the existing wires and the G891 ignition from the appliance:
Make sure to mark the SENSE
(WHT or ORG) wire with the 3/16” Q.C. terminal before removing it from the ignition. Remove the wires, and
disconnect the 6 Pin wire harness. Remove the mounting screws, and keep the screws for installing the
BGN891 ignition. Remove the G891 ignition.
3. Mount the BASO BGN891 Ignition Control in the same place of the OLD G891, and use the same
screws to secure the ignition in place. One additional 7/64” (0.109”) hole may need to be drilled for a
#6-32 mounting screw.
4. Connect the following Wires and Wire Harness to the BGN891 Ignition Control:
4.1 Plug in the Wire Harness:
4.2 Connect the “GREEN” ground wire to frame:
Connect the BGN (6 pin) Wire Harness into the existing wire harness.
Connect the #6 Ring Terminal to one of the mounting
screws from Step 3.
4.3 Connect the SENSE wire:
Connect the existing WHT or ORG SENSE wire coming from the appliance to
the short ORG jumper wire with the 3/16” Q.C. terminal located on the SENSE terminal of the BGN891
ignition.
4.4 Install the ORG SPARK wire (thick insulation):
Install the 1/4” Q.C. Insulated Terminal (provided in Kit)
onto the SPARK Wire, and connect it to the SPARK terminal on the BGN891 Ignition Control.
