WIRING DIAGRAM KEY

Fig.# 8096.2

The room thermostat should be installed in accordance

with the manufacturer's instructions. The thermostat

heat anticipator should be set at 1.0 ampere (automatic

ignition) and 0.60 ampere (standing pilot) for single

zone installations. For multi-zone applications, the heat

anticipator setting should be based on the ampere load

in the thermostat circuit.

NOTE: If it is necessary to replace any of the original

wiring, it must be replaced with 105°C wire or its

equivalent, except 150° black wire must be replaced

with 150°C wire or its equivalent. See wiring diagram

key for 150°C wire indication.

ELECTRICAL WIRING

The electrical power supply requirement for these

boilers is 115 volts, 60 Hz. Field wiring connections and

electrical grounding must comply with the local codes,

or in the absence of local codes, with the National

Electrical Code, ANSI/NFPA 70-1987. Provide a sepa-

rate fused circuit from the main electrical panel to the

boiler, and a disconnecting means within sight of the

boiler.

Remove the control box cover and make the power

supply connections in the field wiring compartment.

(See general location of controls drawing on page 18).

The pump is supplied and factory wired to operate with

the boiler. The "TH" wire leads are for the room

thermostat or zone valve connections.
