Gas control is NOT serviceable......that is why you don't/won't find info/manuals
Things that will shut off pilot when button released:
A weak thermocouple will drop pilot flame out------replace
A weak magnet in gas control valve will drop out pilot....replace gas control valve
A tripped ECO (one time/one shot high temp t-stat 190*F) will drop out pilot flame.....replace gas control valve (The ECO can be tripped by a 'large pilot flame due to mods on orifice)
Pilot flame MUST engulf tip of thermocouple and heat it.
When heated thermocouple generates a milivot signal that holds magnet in gas control allowing gas to flow thru main orifice (12 milivots needed)
IF ECO (Energy Cut OFF------large temp probe that comes out back of gas control and sticks thru WH tank wall into water) trips.......done/no reset
So you have 3 choices......
You could try cleaning off thermocouple with some emery cloth and make sure pilot flame is positioned so it engulfs tip
Replace thermocouple (part# 161156)
Replace expensive gas control valve (part # 161111)
