NOTE: Air may be trapped in the gas supply
line and the gas manifold. A second or third
trial for ignition may be necessary to purge all
the air from the system.
established during the first trial for ignition.
Simply turn of the main switch and turn it back
on that would reset the entire system.
5. The DFC+ will always display the current
discharge air temperature. Press any arrow
key to change the discharge setpoint
temperature. Once an arrow key is pressed,
the LED will display the text for the current
setpoint temperature. Use the down or up
key to set a new discharge temperature,
then press the middle key to save the
changes made. If a key is not pressed for 10
seconds, the DFC+ will exit without saving.
When adjusting the set point range, the set
point cannot surpass the set Low and High

WARNING
If unit fails to ignite or function properly;
disconnect fuel and power supplies and
contact authorized service personnel.
NOTE: If the blower does not turn on, check
the control braker (The "Power" indicator light
will confirm that the control braker is good) or
make sure the VFD is energized.
NOTE: Placing the Main switch in the "OFF"
position will automatically reset the heater if the
control is in a lock out condition. If the burner
still does not ignite, use the following sequence
of steps:
1. Make sure the gas pressure is adequate.
2. Check to make sure all manual valves are
open between the fuel source and the
burner.
3. Check to make sure the proper voltage is
supplied to the heater.

spark voltage to jump to ground before the
igniter. Also check that the ignition wire is
securely fastened
transformer high voltage terminal.
2. Check the burner ports for obstructions.
Remove any obstruction.
3. Check the electrical system including
wiring, connections, switches, and major
electrical components.
