E.
Alliance SL™ Indirect Water Heater
(if used).
1. For wiring refer to wiring diagrams located in this
section and Alliance SL™ Installation Operating
and Service Instructions.
2. Attach junction box extension (4 - 11/16 square) to
junction box on boiler.
3. Steam Boilers only. Verify temperature limit
(Honeywell L4006 or equal, which is installer
supplied) is installed in Tapping "P", refer to
Section V: Piping and Trim.
F.
Wire control circuit
as shown in the appropriate
wiring diagram. See Table 7.
1. A separate electrical circuit must be run from the
main electrical service with an over-current device/
disconnect in the circuit. A service switch is
recommended and may be required by some local
jurisdictions. Boiler is rated for 120 VAC, 60 hertz,
less than 12 amperes.
2. For zone valve wiring, provide separate 24V
transformer rather than attempting to use boiler
mounted control. Consult zone valve manufacturer
for assistance.
G.
Wiring diagram and sequence of operation.
Locate
the system type you are interested in from Table 7, then
refer to the page indicated.
1. Vent Damper Sequence of Operation. See Figure
30.
a. Vent Damper is continuously powered at
Terminal 1.
b. When there is a call for heat, the damper relay
coil is energized through Terminal 5 if all limits
ahead of the damper are satisfied.
c. Relay coil closes contacts, energizing damper
motor, causing damper to open.
d. When the damper blade reaches the fully open
position, power is sent back to the boiler limit/
ignition circuit through Terminal 2 and the
damper motor is de-energized.
e. When the call for heat is satisfied, the damper
relay coil is de-energized—closing contacts
which energize the damper motor. This causes
the damper to close. When the damper blade
reaches the fully closed position, the damper
motor is de-energized.

If system tends to overheat above thermostat's temperature setting, reduce heat anticipator setting by 0.1 or 0.2 amps. If system tends to
shortcycle without reaching desired room temperature, increase heat anticipator setting by 0.1 or 0.2 amps.
