H1 ground heater

[Stevnels17]

Hello! I recently acquired a 1980’s ground heater H1, with a single cylinder Lister Petter engine. It was burning fine until the temperature went crazy and got to almost 400 degrees F. Now it won’t relight, the igniter is working I can see that, but there’s no fuel being introduced. I would guess it tripped a safety? but I’m not sure how those valves work, with the capillary tubes that run from the outlet air and to the bottom of the heat control valve and the temperature valve. Any help is very much appreciated as I can’t find much about this heater! Thank you again!!

Look for a thread titled :
H-1 Ground Support Heater, NSN 4520-01-056-4269
In the Aux Equipment Forum. Might help.

Ok, I have scoured the internet and this forum to no avail. I still don't understand how these valves work or if there one time use. Maybe someone remembers the manufacturer of these valves? Once again thank all you guys for your time!!
