SERVICE HANDBOOK

The three seals on the inner door should be checked every time any service is performed. The sight glass should be checked to insure it is not damaged or missing. The pilot tube and thermocouple routing should be straight (not bent at an angle close to the surface of the seal) as it passes through the pilot assembly seal.

A "five point inner door seal inspection" is outlined below:
