Page 7: Typical Gas Train
ACCESS COMBUSTION, LLC YPICAL RAIN The gas outlet pressure setpoint adjustment screw is in the center of the regulator cover. Clockwise rotation of the setpoint adjustment screw increases the outlet gas pressure. Counterclockwise rotation decreases the outlet gas pressure. The hexagonal cap must be tightened after the setpoint screw has been adjusted and may be sealed from tampering by means of a wire and lead seal.
Page 8: Gas Train Pressure Test
Close the incoming gas valve if main gas pressure exceeds maximum pressure ratings on the gas train. b. Contact your local gas supply company for pressure adjustment. Contact Access Combustion Representative. 3. Check for gas leaks between main incoming gas and valve (2) on the gas train by either performing a bubble test or measuring gas pressure.
