Siemens VGD20.. and VGD40.. gas valves - with SKP2.. (pressure governor)
- Connect the reference gas pipe (
TP
in figure; 8mm-external size pipe supplied loose), to the gas pressure nipples placed on the gas
pipe, downstream the gas valves: gas pressure must be measured at a distance that must be at least 5 times the pipe size.
- Leave the blowhole free (
SA
in figure). Should the spring fitted not permit satisfactory regulation, ask one of our service centres for a
suitable replacement.
