LABEL ALL WIRES PRIOR TO DISCONNECTION
WHEN SERVICING CONTROLS. WIRING ERRORS
CAN CAUSE IMPROPER AND DANGEROUS OPERA-
TION. VERIFY PROPER OPERATION AFTER SERVIC-
ING.
B. Install your Thermostat
The thermostat location has an important effect on the op-
eration of your boiler system. BE SURE TO FOLLOW THE
INSTRUCTIONS INCLUDED WITH YOUR THERMOSTAT.
Locate the thermostat about five feet above the floor on an
inside wall. It may be mounted directly on the wall or on a
vertical mounted outlet box. It should be sensing average room
temperature. Avoid the Following:
Set heat anticipator at 0.7 amps. Connect 24 Volt thermostat
leads to the two(2) yellow wires located in service switch junc-
tion box, located on outer jacket of boiler. See
Figure #13
for
service switch junction box and thermostat field wiring con-
nections.
C. Connect Circulator Pump Wiring
See
Figure #13
(following page) for service switch junction
box and circulator pump field wiring connections. A 5 feet wir-
ing harness with flexible metal conduit is supplied to connect
the circulator pump to the service switch junction box. If the
two 120 Volt circulator wire terminals inside the junction box
are not used, please leave the two wire nuts to prevent the short
circuit.
