Q1: When adjusting the gas flow, the pressure gauge has no data.

A1: The general standard stipulates that the purity of methane gas used should be 98%. The outlet pressure of the gas supply cylinder needs to be adjusted between 0.5 and 1bar. The pressure gauge on the combustion equipment will have a data. If the purity of the methane gas used is low, or the outlet pressure of the gas supply cylinder is not high, the pressure gauge on the combustion equipment does not data.

Q2: After water is injected into the U-shaped pipe, the value of back pressure difference cannot be adjusted.

A2: The U-shaped pipe of back pressure difference is an auxiliary device. To avoid misoperation, it is not enabled by default. If you need to use this function, please remove the left board of the device. A hose connecting the U-shaped pipe inside was tied with a tie. Remove the tie. If you don’t know which one it is, please take a picture and send it to us for confirmation.
