I. MULTIPLE BOILER SYSTEMS
1. Since all heat distribution circulating pumps (CH/
DHW) are connected to the master boiler, it may be
necessary to run one of these pumps to get sufficient
run time on the boiler for any of the commissioning
tests indicated in this section. To do this, choose
“System Test” from the “Installer Menu” on the
master boiler, managing burner display.
a. Use the “
ò
” and “
ñ
” keys to select “Pump for
CH” or “Pump for DHW” from the “System Test”
menu.
b. Note that it is not necessary to operate these
pumps manually when running commissioning
tests on the master boiler. In fact, the master boiler
will automatically activate the CH pump terminals
when operating under system test.
2. If using common venting on multiple boiler systems,
be sure that the Alarm Mode (INSTALLER MENU
Burner Settings Alarm Mode) is set to “Common
Venting” to prevent operation of any of the boilers
without monitoring the flapper valve closure switches.
Turn the power off to one of the boilers (in Standby)
in the system to be sure that the alarm sounds.
