not available, neither the FCM nor the blower will
operate.
The FCM is equipped with a three-prong (grounding)
plug for protection against shock hazard and should
be plugged directly into a properly grounded three-
prong receptacle. Do not cut or remove the grounding
prong from the plug.
Proflame DFC Ignition Module
This is the command center for the appliance. The
DFC Module allows the pilot to run in the Intermittent
(IPI) mode or the Constant (CPI) mode. It signals the
burner to light or shut down and provides the ignitor
with the electricity needed for sparking. The DFC
Module is powered by the FCM when 120V power is
available or by the batteries in the Receiver during a
power outage.
SIT Modulating Gas Valve
The remote transmitter can modulate the valve and
the flame to 6 different settings between high and
low. You can modulate the flame via the remote

yourself or by setting the remote control to the Smart
Thermostat modulation mode. Smart mode means
that as the room temperature approaches the limit set
for shut down the valve will automatically gradually
step down the flame height. The reverse happens
when the room cools - the valve will automatically
gradually increase the flame height.
SIT Split Burner Solenoid
The remote transmitter can toggle between dual
burner, and single burner mode (35,000 Btu/hr or
12,000 Btu/hr).
Pilot Assembly
The pilot assembly consists of a pilot hood, sensor
rod, and ignitor. The ignitor sends a spark to the pilot
hood which ignites the gas and lights the pilot. With
the pilot lit the sensor rod is engulfed by the flame,
flame rectification occurs and the appliance remains
lit. If the sensor does not stay engulfed by the flame
the main burner will not light and the pilot will shut
down.
