A. With main electrical power to the fireplace turned off, install
three AAA sized 1.5V batteries into the remote. Set up remote

B. Turn on the main electrical power to the fireplace. See Figure
39. The red and green control board LED lights will begin to
flash alternately. Each will flash four times, the fireplace will
enter standby and the green LED light only will flash slowly.
Verify power is on by checking if there is power to the circuit
board. If the fireplace has power, the green LED light on the
control board will be illuminated.

C. The Display Panel board should be energized, and a "double
dash symbol" (- -) the power light will be displayed. See Fig-
ure 40. The remote receiver automatically links to the remote
transmitter's signal. If the fireplace does not respond to the
remote when in remote mode as indicated by the double dash
symbol, turn the main power off (Figure 39) and
make sure the remote is on and active before
turning main power back on.
D. Turn on the main gas supply.
CAUTION: If the fireplace experiences an unex-
pected loss of power while the remote is operating
in thermostatic mode, the remote's thermostatic
function will need to be manually reset after power
is restored in order for the fireplace to resume nor-
mal operation. Press the remote's power button to
turn it off then back on to reset the thermostatic
function.

START UP AND ADJUSTMENTS

Sequence of Operations
1. Start the fireplace with the remote, or press the "Mode Se-
lect" button on the fireplace display panel to start the fireplace
manually. The Display Panel will energize, and the desired
flame level will be displayed.
2. The inducer will activate and perform a safety test lasting 45
seconds. The ignition sequence will initiate after this test.
3. The igniter (HSI) will energize and start to glow red.
4. After 20 seconds, the gas valve will open and ignite the burner
on high. The flame sensor will verify the flame is present with-
in six seconds and the green LED light on the control board
will illuminate continuously.
5. The gas valve will adjust manifold pressure and inducer speed
to match desired flame level.
Note: The fireplace will always ignite on Level 5 (High) prior to
adjusting to the flame level on the display panel.
Note: The entire ignition sequence takes approximately one
minute, 15 seconds to complete.
6. Use the Manual Flame Level Adjustment" buttons on the dis-
play panel (Figure 41) or the remote control to change the
flame level setting.
The table below outlines the BTU input rate of the burner for each
flame level.

Note: When changing from a low flame level to a higher flame
level, the fireplace will automatically increase to Level 5 (High)
prior to proceeding to the desired flame level. This is to ensure
consistent operation.

starting on Low speed (l). The Blower speed will display when
the blower turns on.
8. As the Mantis continues to operate, the speed of the circulat-
ing blower will increase, and the symbols for Medium (2) and
High (3) will appear.
