Yes, I have the manual but I'm not legally qualified to tamper with
any part of the gas system.

An FAQ. You need no legal qualifications for doing your own gas
plumbing, only competence. And it is quite possible that you are
competent to replace a thermocouple and clean a gas jet. The main thing
is probably knowing what you don't know, and either finding out or
leaving well alone.
