Manometer - Where to Attach?

[Wandering Sagebrush]

While the furnace, stove, and refer all seem to function normally, I’m going to check my propane pressures to see if I’m not getting enough propane to the Truma burner.   Any words of wisdom on where to attach?  
 

Edit:  The Truma tech (via email) just recommended having a service technician do the pressure check.😕

Ideally  you would connect the manometer in place of the device, in this case the Truma. If that is not practical then try where the gas line Tees off from the main line. If you have the front and rear quick attach propane ports I would also try to get a reading there for a base line.

Another thought is to check where the propane is fed into the Truma to mix with oxygen if it is not completely sealed. There are insects that can get into small spaces and build their nest out of dirt, clay, ash, etc. like a Dirt Dobber only much smaller. They got into my refrigerator propane mixing chamber and restricted the flow enough that it would not burn clean. It was obvious from the soot around the chamber that it was not getting enough oxygen so that might be another sign to look for.

Although I have a Truma I'm not very familiar with them so I'm just spit balling from my experience with other propane devices.

Good luck with getting it figured out and working again.
