I just acquired a used viking range cooktop model number VGRT3604GSS serial number 062403c0000000582 4 burner with griddle. It has #50 orifices with PA070001 regulator.
The problem is when I hooked up to my natural gas line and swapped the reg to ‘nat’ ,no gas comes out to burners. When I switch the reg to ‘lp’ I can get the burners to light but just barely…
I tried setting the air doors and adjusting the mixture screw to no avail…
From what I can research online I have the correct orifice size (#50)
What am I missing?
