Installation Compliance
All field wiring made during installation must
comply with:
- National Electrical Code NFPA 70 and any
other national, state, provincial or local
codes or requirements.
- In Canada, CSA C22.1 Canadian Electrical
Code Part 1, and any other local codes.
ELECTRICAL SHOCK HAZARD.
Before making any electrical connec-
tions to the PRESTIGE, disconnect elec-
trical power supply at the service panel.
Failure to comply can cause severe per-
sonal injury or death.
The line voltage terminals are located on
the right set of terminals 23 through 40.
The low voltage terminals are located on
the left set of terminals 1 through 22.

Line Voltage Connections
1. Connect a dedicated 120 VAC/15A service
to the line voltage terminal on the terminal
block, Fig. 20 on page 31, located internally
in the lower right corner, as shown in Fig.
21.
2. Route the incoming 120 VAC power wire
through the provided openings in the bot-
tom jacket panel.
3. The unit is provided with a service switch
located on the front panel, check local code
requirements for compliance.
If local electrical codes or conditions
require an additional service switch, the
installer must provide and install a fused
disconnect or 15 amp (minimum) service
switch.
8.3
Circulator Wiring
1. The circulator connections used will
depend on the systems piping layout.
All circulators are fused with a common 5A
fuse located on the main control board. The
total combined amp draw of the circulators,
alarm, and flame terminals must not exceed
5 amps at any time. Use an isolation relay to
lower the total combined amp draw if
exceeding this limits.
2. Connect the CH circulator to the line volt-
age terminal on the terminal block, Fig. 20
on page 31, located internally in the lower
right corner, as shown in Fig. 21. This cir-
culator is typically used as the
primary/boiler circulator to supply heat to
the central/space heating loop.
3. Connect the DHW circulator to the line
voltage terminal on the terminal block, Fig.
20 on page 31, located internally in the
lower right corner, as shown in Fig. 21. The
DHW circulator is enabled during a DHW
call. This circulator is typically used to
supply heat to an indirect hot water heater.
4. Connect the P3 circulator to the line voltage
terminal on the terminal block, Fig. 20 on
page 31, located internally in the lower right
corner, as shown in Fig. 21. This circulator
is typically used to circulate water in the
