Figure 4.1: Remote Control LCD Display and Button Functions.
- LCD Display: Shows current room temperature, set temperature, temperature unit (°F/°C), timer, safety lock status, and battery low indicator.
- MODE Button: Cycles through ON, AUTO, and OFF operating modes.
- TIMER Button: Activates and adjusts the timer function.
- Up/Down Arrows: Adjusts set temperature and timer values.
- Built-in Sensor: The remote control contains the temperature sensor for thermostat operation.
4.2 Receiver
The receiver unit acts as a wireless switch for your fireplace. It connects directly to the millivolt valve and receives commands from the remote control. It features a manual ON/AUTO/OFF switch and a 'LEARN' button for pairing.

Figure 4.2: Receiver Box and Wall Plate.
- ON/AUTO/OFF Switch: Allows manual control of the fireplace directly from the receiver.
- LEARN Button: Used to establish communication between the remote and receiver.
- Battery Compartment: Houses 4 AA batteries for power.
5. Setup and Installation
5.1 Battery Installation
Batteries are not included in the kit and must be purchased separately.

Figure 5.1: Battery requirements for the remote and receiver.
- Remote Control: Requires 2 AAA batteries. Open the battery compartment on the back of the remote and insert the batteries, observing correct polarity.
- Receiver: Requires 4 AA batteries. Open the battery compartment on the receiver box and insert the batteries, observing correct polarity.
5.2 Receiver Wiring to Millivolt Valve
This system is designed for millivolt gas valve systems. It functions as an on/off switch and connects to the TH and TH/TP terminals of your millivolt valve.

Figure 5.2: Connecting the receiver to the millivolt gas valve.
- Ensure the gas supply to the fireplace is turned off before beginning installation.
- Locate the millivolt valve on your gas fireplace. Identify the TH and TH/TP terminals.
- Connect the two wires from the receiver to the TH and TH/TP terminals of the millivolt valve. The connection is non-polarized, so the order of the wires does not matter.
- Mount the receiver box in a suitable location, either inside the fireplace control area or on a wall using the provided wall plate and screws. Ensure it is away from direct heat.
- Restore the gas supply to the fireplace.

5.3 Pairing the Remote and Receiver
After installing batteries and wiring the receiver, you need to pair the remote control with the receiver.
- On the receiver unit, slide the switch to the 'ON' or 'AUTO' position.
- Press and hold the 'LEARN' button on the receiver until you hear a beep or see an indicator light flash (refer to receiver for specific indicator).
- Within 10 seconds, press any button on the remote control. The receiver will beep again or the light will stop flashing, indicating successful pairing.
- Test the connection by pressing the ON/OFF buttons on the remote. The fireplace should respond.
6. Operating Instructions
6.1 Power On/Off
- To Turn On: Press the 'MODE' button on the remote until 'ON' is displayed, or press the 'Up' arrow button.
- To Turn Off: Press the 'MODE' button on the remote until 'OFF' is displayed, or press the 'Down' arrow button.
6.2 Mode Selection
Press the 'MODE' button on the remote to cycle through the following operating modes:
- ON Mode: The fireplace will remain continuously on until manually turned off.
- OFF Mode: The fireplace will remain continuously off.
- AUTO Mode (Thermostat): The fireplace will turn on and off automatically to maintain the desired set temperature. The remote's built-in sensor measures the room temperature.
6.3 Thermostat Function (AUTO Mode)

Figure 6.1: The remote control houses the temperature sensor.
- In AUTO mode, use the 'Up' and 'Down' arrow buttons to set your desired temperature. The remote will display both the current room temperature and the set temperature.
- To switch between Fahrenheit (°F) and Celsius (°C), refer to the remote control's specific instructions (usually a combination button press or a switch in the battery compartment).
- The fireplace will activate when the room temperature drops below the set temperature and deactivate when it reaches or exceeds the set temperature.
6.4 Timer Function
- Press the 'TIMER' button to activate the timer.
- Use the 'Up' and 'Down' arrow buttons to set the desired duration for the fireplace to operate (e.g., 30 minutes, 1 hour).
- The fireplace will automatically turn off once the set time has elapsed.
6.5 Child Safety Lock
The child safety lock prevents accidental activation of the fireplace.

Figure 6.2: Activating the Child Safety Lock.
- To Lock: Press and hold the 'Up' arrow button and the 'TIMER' button simultaneously for a few seconds until a lock icon appears on the LCD screen.
- To Unlock: Press and hold the 'Up' arrow button and the 'TIMER' button simultaneously again until the lock icon disappears.
7. Maintenance
7.1 Battery Replacement
When the battery low indicator appears on the remote control's LCD screen, replace the batteries within two weeks to ensure continuous operation.
- Remote Control: Replace with 2 new AAA batteries.
- Receiver: Replace with 4 new AA batteries.
- Always use fresh, high-quality alkaline batteries.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fireplace does not respond to remote control. | Low batteries in remote or receiver. Remote and receiver not paired. Receiver switch in 'OFF' position. Remote out of range. | Replace batteries in both units. Re-pair the remote and receiver (Section 5.3). Slide receiver switch to 'ON' or 'AUTO'. Move closer to the receiver (within 65 feet). |
| Fireplace turns on/off unexpectedly in AUTO mode. | Temperature sensor (in remote) affected by drafts or heat sources. Large temperature hysteresis (5°F/3°C). | Relocate the remote control to an area with stable ambient temperature, away from direct heat or cold drafts. Note that the system has a built-in 5°F (3°C) temperature differential before activating/deactivating. This is normal operation. |
| LCD display is dim or blank. | Low batteries in remote. | Replace remote control batteries. |
| Child safety lock cannot be disengaged. | Incorrect button combination or duration. | Ensure you are pressing and holding the 'Up' arrow and 'TIMER' buttons simultaneously for several seconds. |
| Receiver not powering on. | Low or incorrectly installed batteries. | Check battery polarity and replace with fresh AA batteries. |
