4.2 Cleaning the Gas Valve Vent Tube
This procedure should be performed at least once every 90 days.
1. Set the power switch and the gas valve to the OFF position.
2. Carefully unscrew the vent tube from the gas valve. NOTE: The vent tube may be straightened
for ease in removal.
3. Pass a piece of wire through the tube to remove any obstruction.
4. Remove the wire and blow through the tube to ensure it is clear.
5. Reinstall the tube and bend it so that the opening is pointing downward.
4.3 Cleaning and Adjusting the Combustion Air Blower
1. Unplug the cooker. Mark and disconnect the four wires running from the motor at the inline
connectors.
2. Remove the four nuts and bolts securing the blower to mounting bracket. Remove the blower
from the cooker.
3. Remove the three fasteners that secure the blower motor assembly to the blower housing, and
separate the two components.
Remove these fasteners.
(On black-colored FASCO
blowers there are three
nuts. On silver-colored
KOOLTRONICS blowers
there are three screws.)
4. Wrap the motor with plastic wrap to prevent water from entering it. Spray degreaser or deter-
gent 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.
