RCTS-MLT Remote Control Kits
-For use with SIT Millivolt Valves only-
- Installation and Operating Instructions -
INTRODUCTION
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).
The remote control system can be operated thermostatically
or manually from the transmitter. The system operates on
radio frequencies (RF) within a 20 foot range. It can be
used with Standing Pilot systems only.
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 temperature,
target temperature, timer setting, on/off status, low battery
indicator, current time, burner/valve operation and fan
operation. Electrical ratings for the receiver are: 110 VAC,
60 Hz, 6 W.
WARNING
• Wire 110V to electrical junction box.
• Do NOT wire 110V to valve.
• Do NOT wire 110V to wall switch.
• Incorrect wiring will damage millivolt
valves.
If pertinent, see additional fireplace wiring diagrams on
pages 9 & 10.

comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference
in a residential installation. This equipment 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 guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or
more of the following measures:
It is the responsibility of the installer to read all instructions
before starting installation and to follow these instructions
carefully during installation. Modification of the remote
control system or any of its components will void the
warranty and may cause a fire hazard.
NOTE: A manometer MUST be used to set the manifold
pressure on the gas valve.
WARNING
EXPLOSION RISK!
- Reorient or relocate the receiving antenna.
• Incorrect setting on regulator tower may
cause delayed ignition.
• The regulator tower is preset for NG.
LP installation will require resetting the tower.
- Increase the separation between the equipment and
receiver.
- Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
NOTE: The factory installed junction box in the gas fireplace
must be wired with 110 VAC before installing this kit. See
Installation Instructions section.
- Consult the dealer or an experienced radio TV technician
for help.

2. Ensure the rubber gasket (D), which is pre-fitted as
part of assembly (E), is properly positioned and install
the new pressure regulator tower using the supplied
screws (F). Tighten screws securely (Reference torque
= 25 lb-in.) and remove cover screw (G).
3. Insert the correct plunger into the flame control
solenoid (BLUE = NATURAL GAS, RED = PROPANE).
