**Looking for some insight/suggestions to address a problem concerning my
propane gas heat and glo fireplace that has a pilot light assembly with
both the
thermocouple and thermopile. On the recommendation from my technician I
replaced my whole pilot light assembly due to a pilot light flame and
thermopile
issue. My problem lies with the flame decreasing when I switch from the
pilot
mode to the on position. In pilot mode the pilot lights up with no problem
and a
very strong flame which engulfs both the thermocouple, as well as, the
thermopile. As I move it over to the on position the flame starts to
decrease.
I can move the knob slowly towards the on position enough for the main
burner to
engage, but if I move it over enough to fully open up the main valve, the
flame
no longer covers the thermocouple and/or thermopile enough to keep the
millivolts needed to properly run the main valve. the result is a clicking
sound
and shut off of the whole system. Also, I notice that the knob on the
control valve for the
main burner which regulates the flame itself has no impact on the
intensity of
the flame I can move it from the low position to the highest with no
increase in flame. Since it is a brand new pilot light assembly and the
millivolts from
the termopile are strong, I believe the problem lies in the gas valve
itself.
Wall switch checks out fine and all the connections seem to be in order.
Any
insight would be welcomed. Thanks, Tom******__**

Gas supply line valve open all the way ? Pipe partially blocked ? Sounds
like low gas pressure if the pilot goes low/off when the main burner is on .
The fact that the control knob makes no difference in flame size is also a
clue . Or it could be a bad gas valve assembly - but I'd check the gas
pressure before I replaced it .

It's propane so I'd add to the above any chance't the supply tubing has
been crushed somewhere or foreign obstruction (which is kinda' covered
above).

It's clearly a supply issue -- possibly the bottle/tank regulator is bad
or not fully open as also noted above.
