EMP Installation & Service Manual
109529-03 - 11/19
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, and/or the CSA C22.1 Electric
Code.
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 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.
4. Use anti-short bushings on all wiring passing
through boiler jacket, junction boxes and/or
control boxes.
5. Use armored cable (BX) over all exposed line
voltage wiring.
6. If an Alliance ™ SL water heater is used, use
priority zoning. Do not use priority zoning for
Hydo-Air Systems.
7. Wiring should conform to Figures 23 or 24.
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 23 and 24 for
desired system and heat anticipator setting. 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.
