Push the program button one time on your receiver and you should hear the 3 short beep telling you the receiver is now ready to accept a new code from the remote transmitter.2. Now push the On/Off button of your remote transmitter and you should hear 4 beeps from the receiver telling you the receiver and the remote are now paired with the same RF code and ready to be used.3. If after you have performed this procedure you are still not able to control your gas log set remotely then the most common failure part is the receiver.Alternate part Numbers for the SIT 0.584.040 are:SIT Controls 0584040Ambiance Fireplaces: 308-6014SIT Controls 0-584-040Kozy Heat part number 700-508Ambiance Fireplaces: 308-6014Enviro 50-3029Archgard: 308-6014Avalon from Travis Industries250 02711Fireplace Xtrordinair from Travis Industries 25002711Hearthstone: 7000-395Lopi from Travis Industries 250-02711Mendota: 05-02-00382RH Peterson Real Fyre: D1-30-709FCC ID : T990558402300 We are sorry but REMOTE PROFLAME TRANSMITTERS and REMOTE RECEIVERS are NOT RETURNABLE for refunds!
