Operation Verification - Domestic Hot Water - Prestige Solo 110 Installation And Maintenance Manual

Start-Up Procedures
6. Allow the boiler to operate and allow the
boiler outlet temperature to reach the set
point temperature.
6180
[ ] This begins the burner shutdown
and post purge cycle. The CH circulator
will continue to run until the room thermo-
stat is satisfied.
7. Lower the room thermostat set point below
the room temperature to end the call for
heat.
1180
[ ] This begins a post purge cycle.
When the room thermostat is satisfied, the
boiler will shutdown. The control module
will close the gas valve and the blower will
continue for 30 seconds for a post purge
cycle before shutting down. If another call
for heat is initiated, the boiler will remain
off for an additional 30 seconds before
starting a new ignition sequence.
7180
[ ] The CH circulator will continue
for a 1 minute post pump cycle. The boiler
is in standby MODE waiting for a call for
heat.
8. Verify the operation of the boiler by repeat-
ing the operational sequence several times.
9. Return the room thermostat to a desired set-
ting. Reconnect the DHW wiring or return
the DHW aquastat to desired setting, plac-
ing the DHW system into operation.
Operation Verification - Domestic Hot
Water (if applicable)
1. As outlined in the verification for space
heating, repeat STEPS 2 through 4.
2. Raise the DHW aquastat setting to initiate a
call for heat. As in the space heating opera-
tion the display should show:
1180
[ ] The prepurge cycle. The boiler
blower and DHW circulator become ener-
gized and the 10 second pre-purge cycle
begins.
2180
[ ] The boiler will begin the ignition
sequence. The same sequence of establish-
ing flame, trail for ignition and attempts for
ignition as described in the space heating
applies for domestic water heater.
4180
[ ] This indicates normal operation
for DHW. The burner will begin modulat-
ing its input based on the length of demand
by the DHW aquastat. The burner will not
go into the low input rate for the 1 minute
flame stabilization period that occurs in CH
mode.
3. Lower the DHW aquastat to satisfy the call
for heat.
1180
[ ] The post purge cycle begins. The
control module closes the gas valve and the
blower continues for a 30 second post
purge.
8180
[ ] The DHW will continue for a 30
second post pump cycle. If another DHW
call for heat is initiated the boiler ignition
sequence will begin immediately.
0180
[ ] Boiler is in standby MODE wait-
ing for a CH or DHW call for heat.
4. Verify the DHW operation of the boiler by
repeating the outline operation sequence
several times.
5. Return the DHW aquastat and room ther-
mostat to the desired setting.
