Check GAS Pressure, FIT Outer Case | Athena Technologies A88028

4.2 CHECK GAS PRESSURE

Remove the pressure test point screw located on the injector feed pipe just left of centre on the fire. Connect a pressure gauge, slide the control knob down to the PILOT/IGNITION position. Keep the knob depressed after the pilot has lit to activate the FSD and then slide the knob to the HIGH position. Check that the gas pressure is as specified in Section 1.0 Technical Data. Turn off the fire and disconnect the pressure gauge. Replace the test point screw, relight the fire and test for gas soundness around the sealing screw using a suitable leak detection fluid.

4.3 FIT OUTER CASE

Align the bottom cut-outs in the outer case with the retaining lugs on the firebox sides. Raise the outer case vertically and then lower to engage the top onto the lugs above the air guide, at the same time ensure that the bottom cut-outs remain on the retaining lugs.
