Burner & Manifold Assembly
To remove the burner & manifold assembly:
1. Disconnect electrical service and turn off gas to the
appliance.
2. Loosen the pipe union external to the unit and remove
the gas line to the gas valve.
3.
Disconnect the orange high voltage spark wire at the
ignition control board.
4.
Disconnect the white flame sensor wire at the flame
sensor on top of the burner assembly.
5. Disconnect the orange and yellow wires at the rollout
switch.
6. Disconnect the red and blue wires at the gas valve.
7. Refer to Figure 9. Remove the two screws on the
burner assembly that secure it to the mounting
brackets. The mounting brackets contain pins to locate
the assembly and hold it in place after the screws are
removed. The mounting brackets are hidden until the
burner assembly is removed.
8. First, carefully pull the burner assembly toward you
until it is clear of the locating pins in the mounting
brackets.
9. Then move the assembly away from the vest panel.
10. Finally, pull the assembly from the unit.
11. Once the burner assembly is removed, the burners
can be cleaned using a bottle brush.
12. For reassembly, follow the above steps in reverse
order.
Control Board Mounting Bracket
The control board mounting bracket is designed to be
removed to allow component access for some service
procedures. The ignition control board and the inducer
prover switch are mounted to the bracket.
1. Disconnect electrical service and turn off gas to the
appliance.
2. Loosen the two screws securing the control mounting
bracket (it is not necessary to completely remove
them).
