9.  Detach the orifice fitting assembly from the gas flex line by using a 

wrench to hold the small brass hex nut on the gas flex line, while 
simultaneously using another wrench to rotate the orifice holder 
(large aluminum 7/8-inch hex nut) until the gas flex line is released 
(see Figure 107 and Figure 108). 

10. Unscrew the slip nut on the orifice fitting assembly to remove it 

from the air shutter (see Figure 107 and Figure 108). 

NOTE:

 When installing an orifice fitting assembly, make sure to 

use pipe sealant on the 

orifice

 threads. Make sure no pipe 

sealant gets on the slip nut, as it must spin freely to screw into the 
air shutter.

11. Remove and retain the two T-20 screws from the bake burner 

bracket (see Figure 106). 

12. Gently pull bake burner out of the slot in the oven cavity 

– with the 

hot surface igniter (HSI) attached. See Figure 109.
