VA8LB010Communications Receiver

The F-40 and the F-50 transmitter units have been approved for use with most Wolf Steel gas fi replaces using a millivolt system. The Receiver (W660-0076) can be installed in either the fi replace or be wall mounted depending on the application. The F-40 provides on/off status, and the current room temperature as well as having a low battery indicator. It allows you to switch the fi replace on or off from anywhere in the room. The F-50 is a thermostatically controlled transmitter that provides on/off status, displays room/set temperature as well as having a low battery indicator. These transmitter kits are tested and safe when installed in accordance with these instructions. Modifi cation of any part of this kit will void any warranty claims and could create a fi re hazard. RECEIVER INSTALLATION: Turn off the electrical power and the gas supply to the fi replace. (Gas supply may need to be disconnected from the gas control valve.) Make sure the slide switch on the receiver is set to the OFF position. 1. Either disconnect or connect in parallel* with any other transmitter wiring from the valve. Attach the wires from terminal 1 (TPTH) and terminal 3 (TH) of the gas valve to the output terminals on the receiver. *INSTALLER: It may be advisable to connect a switch with short lengths of wire to minimize the resistance. This will allow the homeowner to continue to control the burner in the event of battery failure. For all millivolt switch wiring, hook up the switch leads on terminals 1 and 3 of the gas valve. WALL MOUNT: 2. Press the battery compartment slightly into the receiver and release enabling the battery compartment to pop out. Pull off the slide switch. Slide the receiver out of the fi replace mounting plate. 3. Using the screws provided secure the receiver and the face plate to an existing junction box. 4. Replace the slide switch. Place 4 AA batteries into the battery compartment and slide the compartment back into the receiver. 5. If the gas supply was disconnected at the valve, leak test using a soap and water solution. Turn electricity back on. FIREPLACE MOUNT: For stove and insert models: do not install the receiver in the gas control valve compartment as this area becomes too hot. On stoves, it may be installed in or behind the pedestal; on inserts, it may be installed behind the fl ashings or a similar convenient location. In a zero clearance model: the receiver may be installed in the gas control compartment. 2. Ensuring that the mounting location will allow for the battery compartment to slide out, secure the receiver to an appropriate location depending on the fi replace model using the screws provided and/or the adhesive pad. 3. If the gas supply was disconnected at the valve, leak test using a soap and water solution. Turn electricity back on.

RECEIVER OPERATION: The receiver switch must be in the TRANSMITTER position for the transmitter to function. F-50 THERMOSTATIC FUNCTION: Thermostatic control automatically cycles the fi replace on and off to maintain the desired room temperature. To turn the fi replace burner on, press the (ON/OFF) button. The LCD will display the word “ON” and the fl ame indicator will be shaded in. The (ON/OFF) button is used to turn the fi replace on or off only. It does not set temperature. The (THERMOSTAT) button is used to control room temperature. Once pushed, “ON” lights up next to the thermostat bulb located in the top left corner of the LCD screen. Set desired room temperature using the (UP) and (DOWN) buttons. If the temperature of the room exceeds the desired room temperature, the thermostat will automatically turn the fi replace “OFF”. CAUTION: In the event that the transmitter fails to send a signal to the receiver for a period of twenty-four hours, the receiver will automatically turn OFF the fi replace. This may occur if the set temperature is not reached, if the transmitter is out of range (25 feet), or if the transmitter batteries fail. The twenty-four hour safety timer allows the receiver to assume control of the fi replace after two hours of uninterrupted operation. After two hours of continuous operation by the fi replace the receiver will cycle OFF for 30 minutes and ON for 20 minutes for the next four hours. If a signal has not been received after twenty-four hours the receiver will shut OFF the fi replace. Press the AUTO ON/OFF button on the transmitter to reset the transmitter, then press the AUTO ON/OFF button again to resume operation. The six hour safety timer may be disengaged by moving the toggle switch on the back of the receiver. Factory setting is ON. Changing the switch will allow the fi replace to run continuously if required. WARNING: In the event of prolonged absences, the F-50 should not be left in thermostat mode. If the transmitter batteries fail while the fi replace is operating the receiver will assume control and shut OFF the fi replace after twenty-four hours. If the transmitter batteries fail while the fi replace is not operating the fi replace will remain OFF. TEMPERATURE FUNCTION: Remove the battery cover on the back of the transmitter to expose the °C/°F dip switch. Move the dip switch to your desired temperature mode. Selected mode will appear in the right corner beside …
