Check fl ame and combustion
4. Place the boiler into the active position by pressing the
RIGHT SELECT [ON] key (FIG. 8-1, page 43).
5. Locate the pinhole button below the RESET button on
the display board (FIG. 8-1). Insert a thin wire (such as
a paper clip) into the hole and press the button once
and hold for 5 seconds to place the boiler into Service
Mode. In Service Mode the boiler will fi re at ignition
speed and will then modulate up to full fi re.
6. Once the boiler has modulated up to full fi re, measure
the combustion. The values should be in the range
listed in Table 7A below. The CO levels should be less
than 150 ppm for a properly installed unit.
If the combustion is not within the specifi ed range,
reference the Troubleshooting Section of the Outdoor
Knight XL Service Manual for possible causes and
corrective actions.

Once the combustion analysis is complete, test the
safety shutoff device by turning the manual shutoff
valve to the OFF position and ensuring that the boiler
shuts down and registers an alarm. Turn the manual
shutoff switch to the ON position and reset the control.

Set space heating operation
Determine controlling sensor
For space heating systems, the temperature control can be
based on one of three sensors; the inlet, outlet, or system
supply sensor. The SMART SYSTEM control is programmed
at the factory to control the temperature of the outlet
sensor. The control will automatically switch to the system
supply sensor once it is connected. If it is desired to base
the temperature control on the inlet sensor, the appropriate
parameter must be changed in the control. See the Outdoor
Knight XL Service Manual for a detailed explanation of this
procedure.
Verify space heat circulator mode
The Space Heating Mode controls both the system pump
(if connected), and the boiler pump. When the SMART
SYSTEM control receives a space heating call for heat, it turns
on the system pump. If the boiler is not heating an indirect
DHW (Domestic Hot Water) tank, and the set point is not
met, it also turns on the boiler pump. After the space heating
call for heat ends, the system pump continues to run for a
short period of time. The system pump can be programmed
to run continuously, except during outdoor shutdown. If
the boiler pump was running, it continues to run for a short
period of time as well. These pump delays are factory set to
30 seconds. If different delays are desired, the appropriate
parameters in the control must be changed. See the Outdoor
Knight XL Service Manual for a detailed explanation of this
procedure.
Adjust set point temperature(s)
Please note that the brackets ([]) denote
NOTICE
screen status.
The NAVIGATION dial may be used during normal
operation to adjust the space heating and tank set point
temperatures.
1.
From the Status Screen press the NAVIGATION dial.
2.
Turn the NAVIGATION dial counterclockwise to select
the appropriate set point.
3.
Press the NAVIGATION dial to adjust the temperature.
4.
Once the desired temperature is displayed, press the
RIGHT SELECT [SAVE] key.
5.
If necessary repeat Steps 3 and 4 to make adjustments to
additional set points.
6.
Press the RIGHT SELECT [HOME[ key to upload the
changes.
7.
If the RIGHT SELECT [SAVE] key is not pressed, the
