Maintenance Procedures

Check Control Wiring

Inspect all control wiring. Ensure wiring is in
good condition and properly connected.

Check Control Settings

1. Set the control display to PARAMETER
mode and check all boiler settings. Adjust
setting as necessary see page 45.
2. Check any external limit control settings (if
used). Adjust settings as necessary.
Perform Start-up and Checkout Procedures
Start the unit and perform the start-up proce-
dure as listed in this manual.
Verify the cold water fill pressure is correct and
the operating pressure of the boiler is within
normal operating range.
Complete the checkout procedures as refer-
enced in this manual.

Check Burner Flame

Inspect the burner flame through the observa-
tion port on the heat exchanger.
If flame pattern is not fully blue and covers the
entire burner surface during high fire, shut the
unit down and allow it to cool thoroughly.
Close the external manual gas valve on the gas
supply line and disconnect the gas piping to
remove the burner assembly from the unit.
Remove the burner head mounting screws and
remove the burner head, carefully ensure com-
bustion chamber insulation is not damaged.
See warning on page 55. Inspect the burner
head for deterioration. Use compressed air or
a vacuum to clean the burner head.
Remove the venturi and gas valve assembly
from the blower.
Use the vacuum cleaner or compressed air to
clean the interior of the blower assembly.
Inspect the blower blades to ensure they are
clean and not damaged.
Re-assemble the venturi and gas valve onto the
blower. Ensure the venturi gasket is in good
condition and positioned correctly.
Re-assemble the burner head onto the mount-
ing plate. Ensure the burner head gasket is in
good condition and positioned correctly.
Re-assemble the gas supply connection and
open the external manual gas valve placing the
unit back into service.

Check Flame Signal

The flame signal should be a min. 3µ
Check the ignitor for fouling or damaged
insulation if a low flame signal is read.
Check ground wiring and continuity as a cause
for low flame signal. Replace ignitor if condi-
tions are satisfactory.

Check Combustion Levels

Refer to page 39 of this manual for measuring
combustion levels and burner adjustments.

Check Flue Gas Temperature

1. Adjust the boiler to fire at HIGH fire and
place the control display to INFORMAT I O N
mode, see pages 43 and 45 for procedures.
2. The flue gas temperature is indicated on the
display as the first digit of 5. The measured
temperature (shown as the last 3 digits)
should not be more than 54ºF higher than
the measured supply water temperature.
3. The measured supply water temperature is
indicated on the information display as the
first digit of 1 and the temperature shown
as the last 3 digits.
