Electrical

1. Install wiring and electrically ground boiler in

accordance with requirements of the authority
having jurisdiction, or in absence of such require-
ments the National Electrical Code, ANSI/NFPA
70, and/or the CSA C22.1 Electric Code.

2. A separate electrical circuit should be run from the

main electrical service with a fused disconnect
switch in the circuit.

3. Wiring should conform to Figure 10 and/or 11.

System Controls and Wiring

1. Refer to National Electric Code or Local Electric

Codes for proper size and type of wire required.
Follow Code.

2. Use anti-short bushings on all wiring passing

through boiler jacket, junction boxes and/or control
boxes.

3. Use armored cable (BX) over all exposed line

voltage wiring.

4. If an Alliance™ indirect water heater is used, use

priority zoning.  Do not use priority zoning for
Hydro-Air Systems.

5. Single Zone System –  Connect the system circula-

tor wire leads to the proper locations on the
Aquastat control, L8124C/L8148A.  See Figure 10 or
11.  Connect the thermostat to the ‘T-T’ terminals on
the L8124C/L8148A control.  Set thermostat heat
anticipator settings to 0.60 amps.

6. Conventional Circulator Zoned System – Read,

understand and follow all of the instructions
provided with the Honeywell R8888 control.

7. Conventional Zone Valve Zoned System – Locate

C1 and C2 inside the L8124C Honeywell control.
Connect the two (2) terminals to the system
circulator wire leads, supplied with boiler.

Connect the H1 and H2 terminals inside the R8889
to the ‘T-T’ terminals in the L8124C Honeywell
Control.

Connect the thermostat of each zone and the
circulator for that zone to R8889 panel.  If an
Alliance™ indirect water heater is used, connect
the Alliance thermostat and circulator to the Zone 1
terminals of the R8889.  Set thermostat anticipator
settings to 0.12 amps.

DANGER

Positivel y assure all el ectrical connecti ons  are  unpow ered before  attempting installation or
service of elec tric al components or connections of the boiler or bui lding.  Lock out all ele ctri cal
boxes wi th pa dlock once power is turned off.

WARNING

Failure to properly wire electrical connections to the boiler may result in serious physical

harm.

Electrical pow er may be from more than one source.  Make sure all power is off before

attempting any electrical work.

Each boiler must be protected with a properly sized fused disconnect.

N ever jump out or make inoperative any safety or operating controls.

The w iring diagrams contained in this manual are for reference purposes only.  Refer to the

w iring diagram  of  any  controls  used  with  the  boiler.    Read,  understand and  follow  all  wiring

instructions supplied with the controls.
