GAS VALVE ADJUSTMENT
Let the unit start to cycle and listen carefully to the igni- tion. If the ignition was quiet, the valve will need no adjustment. If it was a loud ignition, the unit rumbles, or there was no ignition at all, follow these steps:
IF THERE WAS NO IGNITION:
1.Make sure the gas valve is in the "on" position, gas is on to the unit, and the gas valve wiring harness is plugged into the gas valve and into the control board.
2.Turn the adjustment screw under the brass cap. Turn one full turn clockwise with a small flathead screwdriver. Turning the adjustment screw clockwise increases the amount of gas.
3.If the unit still does not ignite, turn the adjustment screw two full turns counterclockwise.
IF IGNITION WAS POOR:
1.Look at the color of the flame through the sight glass while the unit is running. If it is green or red in color, or the heater whistles on ignition, turn the adjustment screw counterclockwise at 1/8” turn intervals until the flame turns blue/light blue in color or the whistling at ignition stops. If the flame is very weak or pulsing, turn the adjustment screw clockwise until the flame steadies.
2.Put the gas valve adjustment screw cover back in place and tighten.
3.Put the AdvantagePlus cabinet door back into place.

TROUBLESHOOTING
The appliance controller has many inherent diagnostic and fault detection routines built into its operating soft- ware and hardware. These routines, along with the three digit LED display and nine LED status indicators present on the display panel, can greatly assist the service per- son in quickly pinpointing the source of problems that may occur with the appliance. In certain circumstances, multiple LED's may be lit or flashing to better pinpoint the problem. The following charts, diagrams, and informa- tion can be used during troubleshooting procedures. See also Trouble Shooting Guides and Sequence of Operations at the end of this Use and Care Manual.
