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).
