The control system on this fireplace is powered by the thermocouple and operates on approximately 500mv
(one-half volt). All connections in the wiring must be clean and tight. The wall switch should be located as
near the fireplace as practical. Do not locate the wall switch so that more than the 25 feet of wire provided
must be used. Additional wire and splices will cause a voltage drop and may cause the control system to not
operate.
