Do not use this remote control system on applications with voltages above 30 Volts AC. • This remote control system requires three (3) “AAA” and four (4) “AA” alkaline batteries to power the transmitter and receiver. Wiring must conform to appliance requirement and building codes/ordinances as required by local and national code authorities having jurisdiction. • Do not short (or jumper) across the gas valve terminals to test the remote control installation. This could damage the unit and void the warranty. • This remote control system should only be used as described in this manual. Any other use is not recommended and will void the warranty. NOTE Due to the sensitive temperature monitoring components in the transmitter, it is necessary to allow the transmitter to stabilize to room temperature before accurate room temperatures are displayed. If the transmitter is activated from a severe cold condition, allow 15 minutes for accurate temperature readings to appear on the LCD. WARNING Turn appliance OFF and allow to cool before installing or servicing. DO NOT connect 110-120 VAC wiring directly to the milli-volt gas control valve. The remote operator must be installed exactly as outlined in these instructions. Read all instructions completely before attempting installation. Follow instructions carefully during installation. Any modification of components will void the warranty and may cause a fire hazard. WARNING Low battery power in the transmitter or receiver can affect the operation of the remote control in the AUTO mode. In some cases the unit may not cycle off when the target temperature is reached. 50D0077 Rev 1Page 3 of 10 Ambient Technologies A Division Of MHS L-Bracket Slide Switch Battery Door INSTALLATIONS Remote Receiver: The remote receiver may be wall mounted or installed into the appliance per the appliance homeowner’s manual. Refer to the Homeowner’s Manual for special installation instructions. If wall mounted, the remote receiver must be installed in a junction box with cover plate provided. Failure to follow the installation instructions found in the appropriate Homeowner’s Manual will void the warranty and may cause a fire hazard. Installing Batteries: The remote receiver uses four (4) “AA”- size batteries. To install batteries, 1. Remove the slide switch by gently pulling straight out. 2. Use your thumb and index finger to gently pull down the L-bracket. 3. Open the battery door by pressing the two tabs located on the door. 4. Install the batteries as indicated in the receiver cover. 5. Close the battery door until the door tab snaps in place. 6. To install the receiver into a wall junction box, install the receiver with the screws provided . 7. If you decided to install the receiver into the appliance, reinstall the L- bracket.. 8. Gently, install the slide switch back to the receiver stem. 9. The batteries should be replaced at least once every 6 months or when the battery indicator flashes. Installing Wire: This system comes with an 18 inch pre-assembled wire assembly. Insert the white terminal to the back of the receiver. The terminal wire block can only be installed one way. Do not force the terminal plug onto the receiver. Follow the homeowner’s manual for connecting the two (2) 1/4” female spade terminals to the millivolt valve. For applications longer than 18 inches, use 18 gauge wire, 105ºC rated, with as few splices as possible. Connect to the two (2) 1/4“ female spade wiring terminals. Wire can be no longer than 20 feet. WARNING Make sure that the wires do not contact the appliances any place other than at the terminals. Exposure to temperatures higher than 105C (250ºF) may cause the receiver to malfunction or fire hazard. 50D0077 Rev 1Page 4 of 10 Ambient Technologies A Division Of MHS Wireless Wall Transmitter: Installing Wireless Transmitter to Wall: The wireless transmitter can be installed within a radius of 30 feet with no object in be…
