4.
Disconnect gas supply piping from gas valve at furnace.
5.
Carefully label and remove wires from gas valve and rollout(s), and note the location so each wire can be properly

20. Apply power and check furnace operation.
If this kit will be installed on a 80% LoNOx furnace or a 95% furnace, the burner plate from the existing burner box must be reused.
Failure to use the correct burner plate will result in noisy burner
operation, lighting issues, and improper combustion on LoNOx
models. Failure to install the correct burner plate will result in NOx
screens backing out of burner tubes and shorting the flame sensor
or ignitor.
Effective 4/1/13, the burner box has been modified for installation of the nitride ignitor (S1-02545231000). If the burner
box with a carbide ignitor is being replaced on a furnace, the
carbide ignitor must also be replaced with a nitride ignitor.
10. Remove two screws from bottom side of burner box
assembly. Slide out burner support with attached burners.
