Check the position of the combustion shelf damper plate. Open the front casing door and then
open the combustion door (Refer to STEPS 4 and 5 of Section 2.5.3 Cleaning Procedure on
pages 26-28). Remove the combustion shelf access cover as shown in Figure 76.
Check the position of the combustion shelf damper plate is correct to ensure the air gap is
within tolerance as noted in Figure 77. If necessary, loosen the locking screw, adjust the
position of the damper and tighten the locking screw to hold the damper securely in the correct
position.
Ensure the combustion shelf access cover is securely re-fitted with an intact gasket in place.
