Note: Engaging "LOCK-OUT" does not cancel existing ON or THERMO modes. It only prevents manual operation of the transmitter. To completely disable transmitter signals, set the transmitter's MODE to OFF.

General Information

The remote receiver houses the microprocessor that controls system operation based on commands from the transmitter. It emits one beep for manual ON/OFF commands but no beep for THERMO mode cycling. The receiver has a 3-position slide switch for selecting operation mode: ON, REMOTE, or OFF.

• ON: System remains ON manually until the switch is moved to OFF or REMOTE.
• REMOTE: System operates only when receiving commands from the transmitter.
• OFF: System is OFF.

It is recommended to place the slide switch in the OFF position when away for extended periods. If the receiver is mounted out of reach of children, the OFF position also acts as a safety lock-out.

Installation Precautions

WARNING: This remote control system must be installed exactly as outlined in these instructions. Read all instructions completely before attempting installation. Modifications to the remote control or its components will void the warranty and could cause a fire hazard.

Do not connect any gas valve or electronic module directly to 110-120VAC power. Consult the gas appliance manufacturer's instructions and wiring schematics for proper wire placement. All electronic modules must be wired according to manufacturer specifications.

Wiring diagrams are for illustration purposes only. Follow manufacturer instructions for gas valve and/or electronic module wiring. Improper installation of electrical components can damage the electronic module, gas valve, and remote receiver.

Installation Instructions

The remote receiver can be wall-mounted in a standard plastic switch box or hearth-mounted near the fireplace. Wall mounting in a switch box protects components from appliance heat and potential damage. Protection from extreme heat is crucial; the receiver should be kept away from temperatures exceeding 130°F inside its case. High temperatures also shorten battery life.

When installing the receiver into a switch box away from the appliance, ensure the receiver switch is in the OFF position. The receiver comes with 18 inches of wire. If additional wire is needed, use 18-gauge stranded or solid wire for connections to the millivolt gas valve or electronic module. Ensure splices do not exceed 20 feet and allow enough wire for annual battery replacement.

Wiring Instructions

Installation should be performed by a qualified electrician or gas technician trained with gas appliances and valves. Incorrect wiring can damage the gas valve, electronic module, or remote receiver.

Learning Transmitter to Receiver

Each transmitter has a unique security code. The receiver's LEARN button must be pressed to accept the transmitter's code upon initial use, after battery replacement, or when a new transmitter is purchased. Ensure the receiver's slide switch is in the REMOTE position for learning; it will not learn in the ON or OFF positions. The LEARN button is located inside a small hole on the receiver's front face.

To initiate learning: Use a small screwdriver or paperclip to gently press and release the black LEARN button. The receiver will emit a "beep". Then, press and release the transmitter's MODE button. The receiver will emit several beeps, indicating the transmitter's code has been accepted.

The microprocessor has a timing function for security code matching. If unsuccessful, wait 1-2 minutes before retrying, then attempt up to two or three more times.

Millivolt Valves

Light the gas appliance according to its instructions. Ensure the pilot flame is ON and the gas valve control knob is in the ON position.

• Slide the receiver's 3-position button to ON. The main gas flame should light.
• Slide the button to OFF. The flame should extinguish (pilot remains ON).
• Slide the button to REMOTE. Press the transmitter's MODE button to ON. The main gas flame should ignite.
• Press the transmitter's MODE button to OFF. The flame should extinguish (pilot remains ON).
• Press the transmitter's MODE button to THERMO. Set the transmitter's temperature to at least 2°F (1°C) above the ROOM temperature. The system flame will ignite. Set the temperature at least 2°F (1°C) below the room temperature; the flame will extinguish. The system should then cycle ON/OFF thermostatically approximately every two minutes when the temperature differential is at least 2°F (1°C).

Electronic Ignition Systems

• Slide the receiver's 3-position button to ON. The spark electrode should begin sparking to ignite the pilot. After the pilot lights, the main gas valve should open, and the main gas flame should ignite.
• Slide the button to OFF. Both the main gas flame and pilot flame should extinguish.
• Slide the button to REMOTE. Press the transmitter's MODE button to ON. The spark electrode should begin sparking to ignite the pilot. After the pilot lights, the main gas valve should open, and the main gas flame should ignite.
• Press the transmitter's MODE button to OFF. Both the main gas flame and pilot flame should extinguish.
• Press the transmitter's MODE button to THERMO. Set the transmitter's temperature to at least 2°F (1°C) above the ROOM temperature. The system flame will ignite. Set the temperature at least 2°F (1°C) below the room temperature; the flame will extinguish. The system should then cycle ON/OFF thermostatically approximately every two minutes when the temperature differential is at least 2°F (1°C).

Transmitter Operating Distance

The remote control operates on RF signals sent from the transmitter to the receiver. It is recommended that the transmitter always be within the 20-foot operating range, preferably in the same room as the appliance.

Thermo Updating Feature – Transmitter

This remote control features a THERMO UPDATING Feature in its software, active in THERMO and PROGRAM modes. The transmitter normally reads the room temperature every 2 minutes and sends a signal to the receiver to check against the SET temperature.

Communication – Safety – Transmitter (C/S – TX)

This series includes a COMMUNICATION – SAFETY function for added safety when the transmitter is outside the normal 20-foot operating range. In all operating modes (ON/THERMO/OFF), the transmitter sends an RF signal every 15 minutes to confirm it is within range. If the receiver does not receive a signal for 15 minutes, its IC software initiates a 2-HOUR (120-minute) countdown. If no signal is received during this period, the receiver will shut down the fireplace and emit rapid beeps for 10 seconds, followed by a single beep every 4 seconds until a signal is received. This intermittent beeping can continue for over a year on battery power.

To reset the receiver and resume operation, press the MODE button on the transmitter. The "ON" display must be visible on the LCD screen. This overrides the COMMUNICATION SAFETY operation and returns the system to normal operation based on the selected mode. The COMMUNICATION SAFETY feature will reactivate if the transmitter goes out of range or its batteries fail.
