How do you check a thermopile?
A thermcouple is what keeps pilot on, if your unit has both a thermocouple and thermopile then your pilot CAN stay lit and main burner not come on.do not buy a gas vavle untill you check the thermopile voltage!! very costy blunder.this is how you test it..( open circuit test) Disconnect thermopile leads from valve. take a volt meter set it to millivolts- set it to a mv reading above 500 so that you can test it correctly, my meter has 2000 setting and I use that. connect T/P leads to meter leads.. reading should be 500mv.
( closed circuit test) connect leads of meter to terminals that your thermostat or on/off swich are hooked too, usually top and bottom terminals on most gas valves, turn unit on and reading should be 150mv or more... you need try open circuit. I can test your vavle too if you like keep me posted if I helped or not. 15 yrs experience in gas repairs!!

What color should the flame be on a propane fireplace insert---blue or yellow?
clean burn gas is a blue flame
it is achieved by using the correct jet size for the gas in use and by adjusting the air shroud around the jet opening
if you converted from natural gas to LPG and didn't change the jet size that is one reason
next there is a tin type shroud around the jet area that can be moved back or forward over the big hole that lets air to mix with the gas at the jet
the position of that shroud adjusts the air to gas ratio
If you are not sure of what I am talking about , talk with a gas fitter or have them do the job
