External Wiring

8.2.1 General Requirements

All field wiring must comply with:
• National Electrical Code (ANSI/NFPA 70) for
installations in the U.S., and any other national,
state, provincial or local codes or requirements.
• Canadian Electrical Code Part 1 (CSA C22.1) for
installations in Canada.
WARNING
ELECTRICAL SHOCK HAZARD. For your safety,
disconnect electrical power supply to the
unit before servicing or making any electrical
connections to avoid possible electric shock
hazard. Failure to do so can cause serious injury,
or death.
NOTICE
The low voltage terminals are located at the
bottom of the CTRLMax control module. The
line voltage terminals are located in the lower
left corner as shown in Fig. 32 below.

8.2.2 Line Voltage Connections

1. Connect a dedicated 120 VAC/15A service to the
line voltage terminals located internally in the lower
left corner, as shown in Fig. 32 below.
2. Route the incoming 120 VAC power wires through one
of the provided openings in the bottom jacket panel.
3. The unit is provided with a service switch located
on the front panel, check local code requirements
for compliance.

NOTICE
If local electrical codes require an additional service
switch, the installer must provide and install a fused
disconnect or minimum 15 amp service switch.

External Wiring - EXALT Solo Units

8.3.1 Circulator Wiring

1. The circulator connections used will depend on
the systems piping layout. See Fig. 13 on page 22
through Fig. 22 on page 34 for common system
piping applications and associated circulator
wiring. Consult the Fig. 10 on page 20 and the
EXALT CTRLMax Control Supplement for additional
options.
NOTICE
The circulator output is protected by fuses
on the CTRLMax control module. The total
combined amp draw of the CH, DHW, and
Flame outputs must not exceed 4 amps at any
time for the EXALT 110 and 155 units, or 3 amps
at any time for the EXALT 199 units. Use an
isolation relay to lower the total combined amp
draw if exceeding this limits.
2. Connect the CH circulator wiring to the line voltage
terminals located internally in the lower left corner, as
shown in Fig. 32 on the left. This circulator is typically
used to supply heat to the central/space heating loop.
3. Connect the DHW circulator wiring to the line
voltage terminals located internally in the lower left
corner, as shown in Fig. 32 on the left. This circulator
is typically used to supply heat to an indirect hot
water heater.
4. Connect the system pump wiring to the line voltage
terminals located internally in the lower left corner,
as shown in Fig. 32 on the left.
