Instructions for RF Comfort Control Valve
The Comfort Control Valve allows remote control
of temperature, fan and flame appearance.
1. If the manual switch is in remote position, switch it
to LOCAL. (Fig. 52)
2. Turn the pilotstat knob counterclockwise from OFF
to the PILOT position, push the knob down, and
hold in position. The pilot valve opens and allows
gas to flow to the pilot burner.
3. Push plunger on the piezo until the pilot burner is lit.
When the pilot burner is lit, the LED on the control
will come on after approximately 40
seconds and will provide one short blink
continuously in the normal mode. When the light
turns off (approximately 10 seconds after it has
been continuously red), the receiver/valve is fully
powered.
4. Release the knob. The shaft will move upward. The
pilot burner should now stay burning. If the pilot
burner goes out, repeat Step 2.
5. Turn the knob counterclockwise to the ON position.
If the manual switch is in the LOCAL position, the
main burner will turn on immediately.
6. Upon initial use of a transmitter, a recognition
operation is required between the receiver/valve
and transmitter. Change the switch from LOCAL to
REMOTE. Press the fan or flame button on the
transmitter within 30 seconds. The LED will blink
indicating the transmitter will now work with the
receiver/ valve. If the switch continues in the RE-
MOTE position, the transmitter will now control the
main valve, flame modulation level, and fan control.

Operation of RF Comfort Control Valve
Shutoff Procedure
Transmitter Operation
Refer to Figure 53.
OFF Mode
In the OFF mode, the fireplace flame and fan are off,
the display will show OFF and displays the room
temperature. If the receiver is in REMOTE mode, the
fireplace will shut off.
ON (Manual) Mode
In the ON mode, the room temperature, flame and fan
levels will be shown. MANUAL will appear next to both
the flame and fan icons.
When the control is in the ON mode, the flame levels,
fan levels, and delay timer are changed with the up and
down buttons. To change the flame level, press the
flame button followed by an arrow key. To change the
fan level, press the fan key followed by an arrow key.
Pushing the arrow key once will change the level by
one unit.
If the manual switch is in the REMOTE position, the
transmitter can shut off the main burner and fan.
However, the control is still on and a command from
the transmitter can turn on the main burner or fan.
To shut off the system, turn the pilotstat knob clockwise
to the OFF position. This action closes the main gas
and safety valves. The transmitter cannot turn on the
main burner or fan.
7. If the manual switch is in the LOCAL position, the
valve will be at the highest fixed pressure setting
and the fan will be at the highest fixed speed. The
transmitter will control the fan only.
