Brief Description of the Components
The gas valve is tted with a manual HI/LO knob to allow for man-
ual modulation of the gas outlet pressure to the appliance burner.
The controls are designed to be used with either LPG or Natural
Gas and can be converted by use of an OEM supplied conversion
kit.
The Digital Fireplace Control (DFC) is an automatic gas ignition
system based on a single microcontroller core. This control man-
ages all functions related to ignition, ame sensing and supervi-
sion for atmospheric applications.
The DFC can be set to provide continuous or intermittent ignition
control sequences and ame monitoring with safety shutdown in
case of failure.
The DFC is set up as a stand alone (AC powered system with
battery back up). See Lighting Instructions on page 57 and Wiring
Diagram on page 56.

Troubleshooting
Before proceeding with the procedures in the following trouble-
shooting table, verify that the power supply (AC/DC adapter) is
present and that the batteries inside the receiver and/or optional
battery pack are fresh and installed with correct polarity.
Make sure all the connections between the wire harnesses and
system components are proper and positive.
Verify that the static inlet pressure meets the manufacturer’s rec-
ommended inlet pressure. If necessary adjust the line pressure
regulator.
If the recommended actions for the following troubleshooting chart
do not help to address the problem consider replacing wiring har-
nesses.
