Install Instructions

18
A. INSTALL A ROOM THERMOSTAT on an inside
wall about four feet above oor. Never install
thermostat on an outside wall or where it will be
inuenced by drafts, hot or cold water pipes, lighting
xtures, television, rays of the sun or near a replace.
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 0.6
amp. If system tends to overheat above the thermostat's
temperature setting, reduce heat anticipator setting 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.
B. INSTALL ELECTRIC WIRING in accordance with
National Electric Code or the Canadian Electrical Code
and local regulations. See Figures 13 through 16 for
applicable wiring diagram. 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. When installed, the boiler must be
electrically grounded in accordance with the
requirements of authority having jurisdiction or, in the
absence of such requirements, with the National
Electrical Code, ANSI/NFPA 70, and/or the Canadian
Electrical Code part 1, CSA C22.1 Electrical Code.
For zone valve wiring, a separate 24V transformer is
required rather than attempting to use the boiler
mounted control. Consult zone valve manufacturer for
assistance.
VI. ELECTRICAL
WARNING
The combined boiler and circulator amperage
must not exceed 15 amps.
Install over-current protection in accordance with
authority having jurisdiction or, in the absence of
such requirements, follow the National Electric
Code, NFPA 70, and/or CSA C22.1 Electrical
Code. Do not provide over-current protection
greater than 15 amperes.
C. Refer to Figures 13 and 14 for details on the internal
wiring.
