SECTION
SECTION 1: INTRODUCTION
1.1
1.3.4
The cable used for all wiring must be rated for line
voltage up to 250V.
Failure to follow these instructions will result in
death or electrical shock.
The system control, burners, pump and outside
air blower must be electrically grounded in accordance with the National Electrical Code®
ANSI/NFPA 70 - latest revision.
Before proceeding with the installation of the
ROBERTS GORDON® System Control, check the
following points:
1.3
CHECK INSTALLATION MATERIALS
1.3.1
Thermostats
Only use 24V thermostats with the ROBERTS
GORDON® System Control. Do not use "power
stealing" 24V thermostats. ROBERTS GORDON®
offers a selection of low voltage thermostats
approved for use with the system control.
The thermostats measure the air temperature in
the building. It is important that the thermostat is
located in an area within the heated zone at occupant level. Do not place thermostat in an area
shaded from the low-intensity, infrared heating
system.
Proving switch must be installed on all ROBERTS
GORDON® systems to ensure safety and operation.
System will not operate without proving switch.
Failure to follow these instructions can result in product
damage.
1.4
SAFETY
Your Safety is Important to Us! This symbol is used throughout the manual to notify you of possible fire, electrical or burn
hazards. Please pay special attention
when reading and following the warnings.
WARNING
Installation, Service and Annual Inspection of
controller must be done by an electrician qualified
in the installation of control systems for heating
equipment.
Installation, Service and Annual Inspection must be
done by a contractor qualified in the installation and
service of gas-fired heating equipment.
Read this manual carefully before installation,
operation, or service of this equipment.
Failure to follow these instructions can result in
death, injury or property damage.
Electrical Installation Materials
A 1ph 16A, 120V power supply to the control
panel must be installed in accordance with the
most current National Electrical Code®, local
codes and any site specific diagrams.
Total load powered by the panel must not exceed
16A. Loads totaling more than 16A must be powered from an additional power supply circuit by
the use of a load relay package.
1.3.3
CAUTION
GENERAL REQUIREMENTS
Failure to comply with the installation instructions
will invalidate the limited warranty set out on
Page 11, Section 7.
1.3.2
Vacuum Proving Switch
A vacuum proving switch (P/N 90430600), preset
at 1.7" w.c. is required for installation on the inlet
of the pump. This switch is required to interlock
the operation of the pump with the control panel.
The System Control is capable of giving four
zones of temperature control. The control will give
power output to one pump.
1.2
INTRODUCTION
the pump. The load relay package is required with
the blower. See Page 7, Section 4, Figure 8, for
wiring detail.
WHAT IS A ROBERTS GORDON® SYSTEM
CONTROL?
The ROBERTS GORDON® System Control is an
electronic controller designed for the control of
CORAYVAC® and VANTAGE® EV systems.
1:
Outside Air Supply Blower
For optimum heater performance and safe heating conditions, inspect and maintain heater(s)
before every heating season and as necessary.
Also, know and maintain heater clearances to
combustibles, see heater Installation, Operation
and Service manual for further details. If you
require additional manuals, contact your
ROBERTS GORDON® independent distributor or
Roberts-Gordon at (716) 852-4400 or (800) 8287450 in the U.S., (905) 945-5403 in Canada or at
www.rg-inc.com.
If used, the optional outside air blower is to be
controlled in parallel with the pump. The blower
incorporates a pressure switch which must be
wired in series with the vacuum proving switch on
