3) Preparation
a) Tilt kettle so the burners and ignition controls are accessible from the rear.
b) Remove burner covers located below the burner assembly.
1. Burner shroud bottom cover
2. Burner shroud front and sides
c) Remove lower access panel on kettle supporting column
d) Remove cover on ignition module control
e) Disconnect existing wiring harness from spark electrode and sensor electrode.
f) Disconnect the spark connector and sensor connector at ignition module.
g) Remove sensor and spark wires along with the silicone sealant from the plastic connector
between the supporting column and ignition module box.
h) Thread out both wires and discard.
i) Disconnect fasteners at both ends to remove ground wire for the electronic ignition system.

4) Install Ground Strap
a) Take ground strap from the field service kit (part no. 012845) and attach it to the spark
connector bracket. Use washer and lock washer provided.
b) Form the strap as shown and attach other end of the grounding strap to the kettle ground
connection. Use washer and lock washer provided.
c) After forming the ground strap, excess strap length may be cut
5) Install Ignition Wires
a) Install Igniter Wire Assembly (160995) first.
b) Thread the igniter and sensor end of wire and sleeve assembly though the hole on sheet metal
part provided (burner shroud front – 132289).

c) Place one piece of high temperature heat shrink tube (160466) over the electrode.
d) Pull the electrical connector on wire assembly out of the fiberglass sleeve.
e) Connect the male connector of wire assembly to the spark electrode.
f) Slide the other end of heat shrink tube (160466) over the terminal of igniter wire assembly (Part
No. 160995) and on to the wire past the terminal.
g) Apply heat to heat shrink tube using an industrial hot air blower so that it is shrinks securely
over the base of brass connector, exposed ceramic and electrical connection. Excess sleeve
over the orange wire will not shrink to encase the wire but it should be left open to eliminate
condensation.
h) Pull the high temperature fiberglass sleeve over the heat shrink tube all the way up to the base
of metal bracket so that it completely covers the igniter assembly below the metal bracket.
i) Hold the fiberglass sleeve in this position by clamping a high temperature plastic wire clamp
(160999).
j) Repeat above steps (17 through 25) to install the Sensor wire assembly (160996) to the flame
sensor electrode in identical manner.

6) Route Ignition Wires
a) Route both wire assemblies with fiberglass sleeve along the gas inlet line tie them to
the gas line with high temperature wire ties (160999).
b) CAUTION- Be careful to route the fiberglass sleeve away from the combustion chamber
and maintain it towards the front of the kettle.
c) Once the wire assemblies are inside the trunion arm, route them through the plastic
connector into the ignition module box with fiberglass sleeve intact.
d) Connect the two wires to ignition module.

e) Fill the plastic connector with silicone sealant to prevent moisture migration.
f) Reinstall all panels and burner cover below the burner assembly.
g) Turn on the electric and gas supply and test unit for proper ignition sequence as
described in the operator manual.
