look under the boiler, you`ll see a silver hose with a little handle on it, may be blue or black, with the boiler cold and off, turn this little handle ( you should hear the water starting to flow ) and the guage should start to rise, set it to 1bar or one the number one on the dial. silver house should be connected between the 15mm pipe (seconed from the right) to the 22mm pipe (first on the right)
