service of electrical components or connections
of the boiler or building. Lock out all electrical
boxes with padlock once power is turned off.
!
WARNING
Failure to properly wire electrical connections to
the boiler may result in serious physical harm.
• Electrical power 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.
• Never jump out or make inoperative any safety
or operating controls.
• The primary control may be damaged or may
not function properly if 120 volt power supply is
NOT wired into control as follows:
The 120V interrupted hot (black) wire must be
connected to the primary control black wire, the
120V neutral (white) wire must be connected
to the primary control white wire and the 120V
constant hot (red) wire must be connected to
the primary control red wire.
A. GENERAL
1. Install wiring and electrically ground boiler in
accordance with requirements of the authority
having jurisdiction, or in absence of such
requirements the National Electrical Code, ANSI/
NFPA 70.
2. Refer to National Electric Code or Local Electric
Codes for proper size and type of wire required.
Follow Code.
3. A separate electrical circuit must be run from
the mail electrical service with an over-current
device/disconnect in the circuit. A service
switch is recommended and may be required
by some local jurisdictions.

CL Installation & Service Manual
7. Wiring should conform to Figures 7-1 through
7-2.
B. INSTALL A ROOM THERMOSTAT on an inside
wall about four feet above floor. Never install
thermostat on an outside wall or where it will be
influenced by drafts, hot or cold water pipes,
lighting fixtures, television, rays of the sun or
near a fireplace. Keep large furniture away from
thermostat so there will be free movement of room
air around this control.
Heat Anticipator in Thermostat should be set to
match the requirements of the control to which
it is connected. See Figures 7-1 thru 7-2 for
desired system and heat anticipator setting. If
system tends to overheat above the thermostat's
temperature setting, reduce heat anticipator
settings by .1 or .2 amps. If system tends to short
cycle without reaching desired room temperature,
increase heat anticipator setting by .1 or .2
amps.
