Figure 3.8 Control Module
Control Module Operation
1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 3.8.
OFF Position: Appliance will ignore all power inputs and
will not respond to any commands from a wall switch or
remote. The unit should be in the OFF position during
installation, service, battery installation, fuel conversion,
and in the event that the control goes into LOCK-OUT
mode as a result of an error code.
ON Position: Appliance will ignite and run continuously
in the HI flame setting, with no adjustment in flame
output. This mode of operation is primarily used for
initial installation or power outage operation with battery
backup.
REMOTE Position: Appliance will initiate commands
from an optional wired wall switch and/or the wireless
remote (RC300).
2. If using a wired wall switch with the module in REMOTE
mode, the flame output can be adjusted with the HI/LO
selector switch on the module. See Figure 3.8. Note
that the flame HI/LO selector switch will become inactive
once an optional remote control (RC200/RC300) is
programmed to the control module. Note that the control
module will always ignite the fireplace on HI and remain
so for the initial 10 seconds of operation. If the HI/LO
is switched to the LO position, the flame output will
automatically drop to the lowest setting after the flame
has been established for 10 sec. After this 10 second
period, the flame can be adjusted from HI to LO with
the switch.
3. The control module has safety feature that automatically
shuts down the fireplace after 9 hours of continuous
operation without receiving a command from the RC300
remote.
4. If you intend to use both an optional wired wall switch
and the RC300 remote control to operate your fireplace,
the wall switch will override any commands given by
the remote.
5.
Module Reset
This module may lock-out under certain conditions.
When this occurs, the appliance will not ignite or
respond to commands. The module will go into
lock-out mode by emitting three audible beeps, then
continuously displaying a RED/GREEN error code at
its status indicator LED.

Batteries should only be installed for use during power
outages. See Section H.
