System Test
System Test settings allow the installer or service
person to operate each burner manually at it
maximum, minimum and ignition rates. The following
outlines the system test operation.
a. Managing Burner Only:
•
Eliminate all heat demands to the boiler by
disconnecting the CH thermostat from terminals
#1 & #2 and disconnecting the DHW sensor
or thermostat from terminals #5 & #6.
•
Use the “
ò
” and “
ñ
” keys to position the
arrow at the desired power setting.
•
Press select to activate System Test. The
burner will ignite and then operate at the
selected input rate until “Off” is selected from
the System Test menu or for 1 hour. The
burner may cycle off on limit if the input rate
exceeds the heating load.
b. Dependent Burner Only:
•
Eliminate all heat demands to the boiler by
disconnecting the CH thermostat from terminals
#1 & #2 and disconnecting the DHW sensor
or thermostat from terminals #5 & #6.
•
Use the “
ò
” and “
ñ
” keys to position the
arrow at the desired power setting.
•
Press select to activate System Test. The
burner will ignite and then operate at the
selected input rate until “Off” is selected from
the System Test menu or for 1 hour. The
burner may cycle off on limit if the input rate
exceeds the heating load.
c. Both Burners:
•
Eliminate all heat demands to the boiler by
disconnecting the CH thermostat from terminals
#1 & #2 and disconnecting the DHW sensor
or thermostat from terminals #5 & #6.
•
Start the managing burner, setting it to Ignition
Power in the Service menu.
•
Start the dependent burner, setting it to
Ignition Power in the Service menu.
•
Change the individual burner Power to the
required input rate. Avoid setting a burner to
minimum power and one to high power. (This
may cause a flame failure or flapper valve
error.)
d. Pump For CH/DHW:
•
This function can be used to check the
function of the CH and DHW circulating pump
outputs.
•
While in “Standby” on both burners, choose
the desired pump output from the Installer
Menu, System Test screen on the managing
burner display.
•
The pump terminals should be activated. If the
pumps don’t appear to be operating, check
the voltage on the pump output terminals.
e. Multiple Boiler Systems:
•
These selections may also be used in a
multiple boiler, cascade system when testing a
dependent burner.
•
In multiple boiler systems, these pumps are
to be connected to the master boiler in the
cascade. Therefore, when a dependent boiler
is being tested, there will not likely be sufficient
heating load to run the boiler for very long.
•
In this case, choose “Pump For CH” or “Pump
for DHW” from the System Test menu on the
managing burner display of the master boiler
in the system before running the dependent
boilers.
