Inner Door Gasket Replacement
Procedure.
WARNING
If the information in these instructions is not
followed exactly, a fire or explosion may result causing
property damage, personal injury or death.
Step 10. After inspection of inner door as noted in step 9, completely remove gasket and adhesive residue from
burner and left side inner doors as needed.
Step 11. Use RTV sealant (recommended bead size 1/8") to secure the inner door gasket to the inner door sections
(right & burner). The burner door gasket must be sliced in the location shown on the illustration below in
order to slide the gasket over the burner venturi. Refer to illustration below for proper RTV sealant
application. Note the overlap configuration in the flange area of the inner door. Set the flange section first, this
will help to achieve the proper over lap position.
