Verify power is on by checking if there is power to the control
board. The red and green control board LED lights will be-
gin flashing alternately. Each light will flash four times. Then
the wall furnace will enter remote mode and the green LED
light will begin to slowly flash. The display panel will show a
“double dash symbol” (- -). See Figure 59.

Sequence of Operations
1. Start the wall furnace by pressing the display panel’s “Mode
Select” button once from remote mode to start the wall fur-
nace manually. See Figure 60. The Display Panel will ener-
gize, and the desired heat 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 Hot Surface Ignitor will start to glow red.
4. After 20 seconds, the gas valve will open and the burner will
ignite on high. The flame sensor will verify the flame is present
within six seconds and the green light on the control board will
illuminate. The flame icon will display in the top left corner of
the display panel once the controls verify the flame presence.
See Figure 61.

5. The gas valve will adjust manifold pressure and inducer speed
to match desired heat level.
Notice: The wall furnace will always ignite on Level 5 (High) prior
to adjusting to the heat level on the display panel.
Notice: The entire ignition sequence takes approximately one
minute and 15 seconds to complete.
6. Use the “Adjustment” buttons on the display panel to change
the heat level setting.
Notice: When changing from a low heat level to a higher heat
level, the wall furnace will automatically increase to Level 5
(High) prior to proceeding to the desired heat level. This ensures
consistent operation.
