Urgh.....original question gone to the black hole of the Internet
Issue: Lopi Spirit B-vent natural gas stove
. Cannot get sufficient gas flow to main burner.
I have two of these stoves, one not functioning correctly. This allows me to compare working to non-working. The stove in question worked fine when I shut it down last summer, now giving me grief.
Originally when I turned the problem stove on, pilot would not stay on, so took stove apart and cleaned thermopile and thermocouple of white ash. Millivolts at connections to gas control valve went from < 100 to now 500. Pilot now stays lite and engulfs both thermopile and thermocouple. In my functional stove the mV are mid 700s', but those thermocouple/thermopile were replaced last year with a Travis pilot assembly retrofit, so its not apples to apples. In both stoves, the mV drop drastically when burners are on (not sure why, at the limit of my handiman expertise).
Stove can be triggered to go on with both thermostat
and ON switch, but flames are barely 1-2 inches in back and not at all in front of firebox. Took stove apart again and blew out main burner assembly. No change. Adjusted vent dial and also air shutter inside fire box. No change.
At this point am at a loss for an explaination. I am clearly getting gas to the main burner, just not enough. I can't find a technical manual on line. I have user manual, but it's not much help.
