Control Module Operation
1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 3.6.
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.
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 3.6. Note
that the flame HI/LO selector switch will become inactive
once an optional remote control 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 a safety feature that
automatically shuts down the fireplace after 9 hours
of continuous operation without receiving a command
from the remote.
4. If you intend to use both an optional wired wall switch
and the 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.
• Check battery tray. Remove batteries if installed.
Batteries should only be installed for use during power
outages. See Section I.
• Locate the module selector switch. (See Figure 3.6).
