GAS PRESSURE CHECKS
The gas valve is equipped with ports for testing the manifold pressure and inlet pressure. When checking pressures, follow these steps: Check and adjust (if required) the inlet pressure first and then check and adjust (if required) the manifold pressure.
1.With gas valve knob in “OFF” position, use small screw driver to loosen the screw (turn clockwise) inside the pressure port.
2.Slide 1/4" tube over the port and connect other end of tube to pressure gauge/manometer.
3.Start pilot and burner and read pressure.
4.When finished, shut burner and pilot off, remove tube, tighten screw inside pressure port, and carefully check for leaks.
NEVER increase gas pressure beyond listed limits.
