7.1.1 Remote Control Transmitter
This new remote system has all controls available on its
face for reliable, ease of use. It gives room temperature
readout, set temperature readout, all function abilities as
well as childproof lockout and low battery indicator. Icons
appear on the screen indicating which mode of operation
you are controlling. The four button controls are easy to
learn and simple to operate. The remote transmitter is
powered by 3-1.5v AAA batteries.

or turn off, and provides the ignitor with the electricity
needed for sparking. All functional commands are routed
through this part of the system and distribute the signal
to the appropriate component.
7.1.5Sit885ModulatingValve
This valve has the ability to be stepped down in six
increments between high and low. It can be done
manually or by setting the remote control to the Smart
thermostat modulation mode. Automatic modulation
means that as the room temperature approaches the
limit set for shut down, the valve gradually decreases
or“steps-down”thefireintensity.Conversely,asroom
temperature cools, the valve gradually increases flame
intensity. The overall result is more comfortable even
heating, minimizing temperature peaks and valleys.
7.1.6 Pilot Assembly
The pilot contains a pilot hood, igniter, and a sensor rod.
The igniter sends a spark to the pilot hood which lights
the gas. The sensor rod is then engulfed by the pilot
flame, flame rectification occurs and the unit remains lit.
If rectification does not occur the main burner will not
light and the pilot will shut down.

7.2 Control Functions (Fig. 7.1)
7.2.1 Pilot Mode
In most cases you will want to operate the fireplace
in IPI mode. This allows the most efficient use of gas,
burning the pilot light only when the thermostat calls
for the burner to ignite.
TheCPImodepermitsfunctionalflexibilitywithin
a wide range of installation characteristics. The pilot
flame remains lit when the burner is off. This is an
advantage in those instances when a cold system
maybe difficult to start in IPI mode. The pilot can be
run until the system has warmed sufficiently for IPI
operation.NOTE:THEIGNITORWILLALWAYSSPARK
