Inner Door Removal Procedure (cont’d) 
Step 7. 

Inspect both inner doors for any of the following imperfections: tears,

missing material, cracks, dirt or debris, lack of adhesion to the inner door, material left 
on combustion chamber, or any other imperfections that will inhibit a proper seal. 

If any of the imperfections above are present, replace the inner door gasket following 
the Inner Door Gasket Replacement Procedure.  If not, replacement of the inner door 
gaskets is not necessary. 

Step 1. 

Completely remove all gasket and adhesive residue from the right and 

left side inner doors, as needed. 

Step 2. 

Using RTV sealant, apply a 1/8” bead to secure 

the inner door gasket to the inner door sections.  Refer to the 
illustration for proper application.  Note the overlap 
configuration in the flange area of the inner door.  Set the 
flange section first, and this will help to achieve the proper 
overlap position. 

If the information in these instructions is not followed exactly, a fire or explosion may re-
sult causing property damage, personal injury, or death.
