	Figure 55: Opening Inlet Pressure Tap on
Figure 54: Labeled Gas Valve.	Valve.

TO TEST VALVE PRESSURES:

The pressure taps are located on the front side of the valve (see Figure 54 & 55).

1.Remove the door (refer to MAINTENANCE AND SERVICE - GLASS DOOR REMOVAL), log set and ember material, brick panels, burner tray, and the valve cover to access the valve (refer to MAINTENANCE AND

SERVICE - REMOVING VALVE COVER).

2.Turn set screw one (1) turn counter-clockwise to loosen.

3.Place 5/16 in (8 mm) I.D. hose over the pressure taps.

4.Check pressures using a manometer.

5.When finished, release pressure, remove hose and tighten set screw.

6.Re-install the valve cover, burner tray, brick panels (refer to SECONDARY INSTALLATION - INSTALLING

THE BRICK PANELS), log set and ember material (refer to SECONDARY INSTALLATION - LOG SET AND EMBER

INSTALLATION) and the glass door.

Always check for gas leaks with a soap and water solution after completing the required pressure test.
