To increase the gas flow (or gas pressure) in your fireplace, you'll need to first ignite the fireplace, then turn the gas control knob to open the gas line and increase the flame. If you have done this and it has made no difference to the size of the flame, then you may need to have your system cleaned, or contact your technician to service the fireplace.
