    REMOTE CONTROL RECEIVER REPLACEMENT The remote control receiver and batteries are very sensitive to heat. Exposure to high temperatures can cause the receiver to malfunction and shorten the life of the batteries. If your fireplace does NOT have a restrictive barrier (see page 6), such as glass doors, it is recommended that the remote receiver be affixed to the right hand side of the heat shield or placed in the front, right corner of the fireplace.
