Pilot flame height is a result of propane pressure and pilot orifice size (earlier models had an adjustment screw but it had little affect)
Pilot flame has to engulf tip of thermocouple.
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)
Main Flame will not/can not occur until pilot flame stays lit
