REMOTE RECEIVER
The remote receiver operates on 4 AA-size 1.5V batteries. It is recommended that ALKALINE batteries be used for longer
battery life and maximum microprocessor performance. IMPORTANT: New or fully charged batteries are essential for
proper operation of the remote receiver.
The remote receiver houses the microprocessor that responds to commands from the transmitter to control system
operation. The remote receiver has a 3-position slide switch for selecting the MODE of operation: OFF/REMOTE/ON
• With the slide switch in the ON position the system will remain on
until the slide switch is placed in the OFF or REMOTE position.
• With the slide switch in the REMOTE position (centered), the
system will only operate if the remote receiver receives commands
from the transmitter. If the system does not work see LEARNING
TRANSMITTER TO RECEIVER Section.
• With the slide switch in the OFF position the system is OFF.
• It is suggested that the slide switch be placed in the off position
if you will be away from your home for an extended period of time.
Placing the slide switch in the OFF position also functions as a
safety “lock-out” by both turning the system off and rendering the remote receiver inoperative.

INSTALLATION INSTRUCTIONS
WARNING
This remote control system must be installed exactly as outlined in these instructions. Read all instructions completely
before attempting installation. Follow instructions carefully during installation. Any modications of the remote control or
any of its components will void the warrant and may be pose a re hazard.
Do not connect any gas valve or electronic module directly to 110-120VAC power. Consult gas appliance manufacturer’s
instructions and wiring schematics for proper placement of all wires. All electronic modules are to be wired to manufactur-
er’s specications.
The following wiring diagrams are for illustration purpose only. Follow instructions from manufacturer of gas valve and/or
electronic module for correct wiring procedures. Improper installation of electric components can cause damage to elec-
tronic module, gas valve and remote receiver.
RECEIVER INSTALLATION
The remote receiver can be either wall-mounted in a standard plastic switch box or placed on or near the replace hearth.
Preferably, the remote receiver should be wall-mounted in a plastic switch box. When locating the receiver at the hearth
PROTECTION FROM EXTREME HEAT IS VERY IMPORTANT. Like any piece of electronic equipment, the remote
receiver should be kept away from temperatures exceeding 130º F inside the receiver case. Battery life is also
signicantly shortened if batteries are exposed to high temperatures.
Make sure the remote receiver switch is in the OFF position. It is recommended that 18 gauge solid or stranded wires
(included) be used to make connections between the terminal wiring block on the millivolt gas valve or electronic module
and the wire terminals on the remote receiver. For the best results use wire with no splices and measuring no longer than
20-feet.
NOTE: This product is designed for use with an attended hearth appliance or re feature. Adults must be present when
the Control System is operating. DO NOT program or thermostatically set this Control to operate a hearth appliance
or re feature when adults are not physically present. Furthermore, DO NOT leave the hearth appliance or re feature
burning unattended; it may cause damage or serious injury. If an adult is going to be away from the hearth appliance or
re feature for any length of time, then the handheld/wall mount, receiver/control module and application should be in the
“OFF” position.

Model: 4001TH-A TX REV. 3-31-20 Page 4
HEARTH MOUNT
The remote receiver can be placed on the replace hearth or under the
replace, behind the control access panel.
Position where the ambient temperature inside the receiver case does
not exceed 130º F. NOTE: Black slide button (accessory pack) is used
on Hearth Mount Applications.
WALL MOUNTING RECEIVER
Install (4) AA-size 1.5 ALKALINE batteries in the remote receiver. For best performance, remote receiver batteries should
be factory fresh when installed. Very little battery power is required to operate the remote receiver, but the electronics are
tuned to operate best when total battery output is greater than 5.3 volts. Four new AA batteries should provide a total
output voltage of 6.0 to 6.2 volts. Be sure batteries are installed with the (+) and (-) ends facing the correct direction.

Operation of the remote receiver is similar to that of a thermostat in that both
turn the gas valve ON and OFF based on input signals. A thermostat’s input
signals are different temperatures. The remote receiver’s input signals come
from the transmitter.
Connect each of the two wires leading from the TH terminals
on the millivolt gas valve to either of the two wire terminals on
the remote receiver. Normally it does not matter which wires
go to which terminal. They are not poloaity sensitive.

icon will appear and replace should light.
•Set the SET temperature to at least 1°F (1°C) below the room temperature and the system ame will extinguish in a
few seconds. Thereafter, it should continue to cycle ON and OFF thermostatically approximately every two minutes as
the ROOM temperature changes, but only when the temperature differential between ROOM and SET temperatures
differ at least 1°F (1°C). (The 1°F differential is the factory setting).
BATTERY LIFE
Life expectancy of the alkaline batteries in the transmitter should be at least 12 months. Check and replace all batteries
annually. When the transmitter no longer operates the remote receiver from a distance it did previously (i.e. transmitter’s
range has decreased) or the remote receiver does not function at all, the batteries should be checked. It is important that
the remote receiver batteries are fully charged and provides continuous output voltage of a least 5.3 volts. The transmitter
should operate with as little as 2.5-volts battery power.
TROUBLE SHOOTING
If you encounter problems with your replace system, the problem may be with the replace itself or it could be with the
remote. Review the replace manufacturer’s operation manual to make sure all connections are properly made. Then
check the operation of the remote in the following manner:
• Make sure the batteries are correctly installed in the RECEIVER. One reversed battery will keep receiver from
operating properly.
• Check battery in Transmitter to make sure it is installed with the (+) side up.
• See LEARNING TRANSMITTER TO RECEIVER section.
• Keep RECEIVER from temperatures exceeding 130º F. Battery life shortened when ambient temperatures are above
130º F.
• If RECEIVER is installed in tightly enclosed metal surround, the operating distance will be shortened.
• Ensure the transmitter is within 20-25 feet of the receive for proper operating range.
LEARNING TRANSMITTER TO RECEIVER
Each transmitter uses a unique security code. The receiver will learn up to three (3) security codes. It will be necessary to
press and release the LEARN button on the receiver to accept the transmitter security code upon initial use or if a
replacement transmitter is purchased from your dealer or the factory. In order for the receiver to accept the transmitter
security code, be sure the slide button on the receiver is in the REMOTE position; the receiver will not LEARN if the slide
switch is in the ON or OFF position. The LEARN button in located on the front face of the receiver; inside the small hole
labeled LEARN. Using a small screwdriver or a tip of a pencil gently press and release the LEARN button inside the hole.
When you release the LEARN button the LED light on the receiver will begin ashing every 1-second. Press ANY button
on the transmitter and release. The LED light will ash quickly, indicating that the transmitter’s code has been accepted
into the receiver. To “clear” the learn memory, press and hold the learn button for 10-seconds. The LED light will ash
three (3) times to indicate the memory is cleared.
