  DISCONNECT ELECTRICAL POWER 

             to the boiler and heating system before 

servicing. Positively assure that no voltage is 

present. Lock electrical boxes to prevent someone 

from inadvertently restoring power before the 

heating system is safe to operate.

  NEVER DEFEAT OR JUMP OUT safety 

             devices.

  PROTECT EACH BOILER circuit with a 

             properly sized over-current protection 

device.

  MAKE ELECTRICAL CONNECTIONS 

             CAREFULLY according to the boiler’s 

wiring diagram and instructions

Refer to the Internal Wiring diagrams later in this 

manual.

Locate the wiring box on the left side of the 

boiler and open the cover (Figure 7-a).

  Install a 120V disconnect near the boiler.

  Connect the 120V wiring from the disconnect 

to the boiler's white (neutral), black (hot), 

and green (ground) labeled "120VAC Power 

supply".  Do not reverse polarity.

  Connect the 120V wiring from the circulator 

to the white (neutral) yellow (hot) wires 

marked "circulator".

  WIRE AN ADDITIONAL SAFETY LIMIT 

             such as a low water cutoff or temperature 

limit device, other than an IQ

™ Control device, 

in series with the 120V circuit used to power the 

boiler. Do not alter the boiler’s factory wiring when 

adding an additional limit.

  Connect the 24V wiring from the thermostat 

to the "T-T" terminals on the Option Control 

Panel.

  To connect other external devices, refer to 

the instructions included with these devices.
