1 FOR REVIEW ONLY FCC REQUIREMENTS WARNING: CHANGES OR MODIFICATIONS TO THIS UNIT NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pur- suant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harm- ful interference in a residential installation. This equip- ment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guaran- tee that interference will not occur in a particular instal- lation. Canadian Equipment Requirements This digital apparatus does not exceed the (Class A/ Class B)* limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications. Le present appareil numerique n'emet pas de bruits radioelectriques depassant les limites applicables aux appareils numeriques (de la class A/de la class B)* prescrites dans le Reglement sur le brouillage radioelectrique edicte par le ministere des Communi- cations du Canada. This device complies with RSS-210 of Industry and Sci- ence Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, in- cluding interference that may cause undesired opera- tion of the device.

The system operates on radio frequencies (RF) within a 20 foot range. Can be used with DSI, IPI or Standing Pilot systems. This remote control kit has a hand held transmitter that can be used as a remote on/off or as a thermostat. The transmitter display shows the current room tempera- ture, target temperature, timer setting, on/off status, low battery indicator, current time and burner/valve op- eration. Electrical ratings for the receiver are: 110 VAC, 60 Hz. If pertinent, see additional fireplace wiring diagrams on pages 8 to 10. INSTALLATION PRECAUTIONS This remote control kit is tested and safe when installed in accordance with this installation manual. Installa- tion of this kit MUST be done by a qualified service technician. It is the responsibility of the installer to read all instructions before starting installation and to follow these instructions carefully during installation. Modifi- cation of the remote control system or any of its com- ponents will void the warranty and may cause a fire hazard. NOTE: The factory installed junction box in the gas fireplace must be wired with 110 VAC before installing this kit. See Installation Instructions sec- tion. CAUTION: All wiring should be done by a qualified electrician and shall be in compliance with local codes and with the National Electric Code ANSI/NFPA No. 70-current (in the United States), or with the current CSA C22.1 Canadian Electric Code (in Canada). WARNING: DO NOT CONNECT 110-120 VAC WIRING TO THE GAS CONTROL VALVE OF THIS APPLIANCE. 2 FOR REVIEW ONLY Figure 1 REMOTE RECEIVER Important: The remote receiver should be posi- tioned close to front in right or left corner. The remote receiver is powered by 110-120VAC. It plugs into a standard polarized duplex receptacle. Locating Receiver and Operating Functions This remote receiver can be positioned under the fire- box in the control compartment of the fireplace if ambi- ent temperatures do not exceed 170 0 F. This system is designed to remotely operate the gas valve. INSTALLATION INSTRUCTIONS Installing Electrical Service to the Junction Box WARNING: TURN ELECTRICAL POWER OFF AT THE CIRCUIT BREAKER BEFORE BEGIN- NING THIS INSTALLATION. NOTE: Some appliances do not have a cover plate. Instead, there is a hole through which the Romex clamp is attached to the outer wrap. 1. Remove the electrical cover plate from the lower side of the fireplace. Remove the knock-out from the plate and attach the Romex clamp (screws to the outside) (see Figure 1). 2. Feed the electrical service wires through the Romex clamp and secure the wires to the clamp. 3. Using the wire nuts provided, connect the service wires to the junction box. The black wires to the black service wire, the white wires to the white ser- vice wire, and the service ground wire to the ground stud of the junction box. 4. Re-attach the cover plate to the out- side of the fireplace. WARNING: LEAVE ELECTRICAL POWER OFF AT THIS TIME. DO NOT RESTORE POWER UNTIL THE REMOTE CONTROL SYSTEM IS COMPLETELY INSTALLED. ACCESS HOLE COVER PLATE 110 VAC SERVICE RECEIVER WIRING INSTRUCTIONS Incorrect wiring connections WILL cause damage to the gas valve or electronic module operating the gas appli- ance and may also damage the remote receiver. Wiring Millivolt Valves Connect the remote receiver by connecting each of the two wires leading from the remote receiver to either of the two wire TH terminals on the gas valve (see Fig- ure 2). Normally it does not matter which wires go to which terminal. Figure 2. Wiring Millivolt Valves Alternative Wiring for units with a wall switch Disconnect the wall switch wire from the TH terminal on the valve and connect this wire to male connector supplied on the receiver.

Circuit Description The TX unit is made up of Modulation transmitter, Data memory, Thermo detector, backlight, key board interface, LCD display, low battery detector and CPU clock frequency circuit. 1. The TX unit adopts 2pcs AAA Alkaline battery supply. Crystal X1 4.0MHz and X2 32.768KHz provides U1 CPU HT49R50 with working clock frequency. U3 HT 7027 outputs a low level to U1 when the battery is lower than 2.7V, and then LCD will display low Batter Sign. 2. U1 outputs a group data to Q2 when MODE button is pressed. SAW & Q2 are the modulation transmitter’s main components for modulation mode of ASK. SAW keeps transmitter frequency at 303.8MHz +/-75KHz. Meanwhile, U1 PIN99 outputs a high level to Q1 to drive LED1, LED2, LED3, LED4 light on. The LEDs will be auto off after 8s. 3. U2 (93LC 46B) is a Eeprom component. Thermo-resistor sends detected data to U1 for dealing with, and the results will be showed by LCD . 4. Buttons of UP, DOWN, MODE, SET, TIMER and CP-LOCK are U1 Interface Circuit. LCD displays all U1 processed results.
