PREVENTIVE MAINTENANCE Continued

4.  Wrap the motor with plastic wrap to prevent water from 

entering it.  Spray degreaser or detergent on the blower 

wheel and the blower housing.  Allow it to soak for five 

minutes.  Rinse the wheel and housing with hot tap 

water, then dry with a clean cloth.

5.  Remove the plastic wrap from the blower motor 

assembly.  Reassemble the blower motor assembly and 

blower housing.  Reinstall the blower assembly in the 

cooker and reconnect the wires disconnected in Step 1.

4.  Reinstall the blower shield or shield assembly.

5.  Light the cooker in accordance with the procedure 

described in section - Operating Instructions.

6.  After the burners have been lit for at least 90 seconds, 

observe the flames through the burner view-ing ports.  

The air/gas mixture is properly adjusted when the burner 

manifold pressure is in accordance with the applicable 

table (Burner Gas Pressure- on this page) and the burners 

display a bright orange-red glow.  If a blue flame is 

observed, or if there are dark spots on a burner face, the 

air/gas mixture requires ad-justment.

On the side of the blower housing opposite the motor is 

a plate with one or two locking nuts.  Loosen the nut(s) 

enough to allow the plate to be moved, then adjust the 

position of the plate to open or close the air intake opening 

until a bright orange-red glow is obtained.  Carefully hold the 

plate in position and tighten the locking nut(s).
