DANGER
Drain the frypot or remove the handle from the drain valve before proceeding further.
1. Disconnect the unit from the electrical and gas supplies.
2. Remove the combustion air blower per the procedure found in Section 1.6.6.
3. Remove the four nuts from the air plenum assembly and pull the assembly straight out toward

you. Disconnect the flame sensor wire from the ignitor by gently pulling its push-on terminal
from the terminal strip on the ignitor.
5. Disconnect the flexible gas lines from the burner orifice and the enrichment tube from the ignitor
assembly.
