Yo ur 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.

Installation, service and annual inspection of
controller must be done by an electrician qualified in
the installation and service of control systems for
heating equipment.
Installation, service and annual inspection of heater
must be done by a contractor qualified in the
installation and service of gas or oil fired heating
equipment.

Read this manual carefully before installation,
operation, or service of this equipment.

For optimum heater performance and safe heating
conditions, inspect and maintain heater(s) before
every heating season as necessary. Also, know and
maintain heater clearances to combustibles, see

1.2 What is a ROBERTS GORDON
Control?

The ROBERTS GORDON

®

System Control is an
electronic controller designed for the control of
CORAYVAC

®

and VANTAGE® NP (multiburner only)

systems.

The System Control is capable of giving four zones of
burners' temperature control and power. The control
will also give power output to as many as two pumps,
provided that the load is not greater than 20 A and 1
Ø. For additional electrical specifications see Page 3,
Section 2.2.

SECTION 1: INTRODUC TION

1.3 Electrical Requirements

Failure to comply with the installation instructions will
invalidate the limited warranty set out on Page 17,
Section 7.

The cable used for all wiring must be rated for 600 V.

The system control, burners, pump and outside air
blower must be electrically grounded in accordance
with the following:

United States: Refer to National Electrical Code

®

,
NFPA 70 - latest revision. Wiring must conform to the
most current National Electrical Code

®

, local ordi-

nances and any special diagrams furnished.

Canada: Refer to Canadian Electrical Code, CSA
C22.1 Part 1 - latest revision.

1.4 Check Installation Materials

Before proceeding with the installation of the
ROBERTS GORDON

®

System Control, check the fol-

lowing points:

1.4.1 Thermostats

Electronic 24 Vac thermostats and mechanical ther­mostats with heat anticipator can be used. The sys­tem control offers a 24 Vac power supply to power
electronic thermostats.
Roberts-Gordon offers a selection of low voltage
thermostats approved for use with the system con-
trol.

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.

SYSTEM CONTROL INSTALLATI ON, OPERATION AND SERVICE MANUAL

CAUTION

Product Damage Hazard

Pressure switch must be installed on all
ROBERTS GORDON

®

systems to ensure

safety and operation.

System will not operate without pressure
switch.

Failure to follow these instructions can result
in product damage.

1.4.2 Electrical Installation Materials

120 V, 60 Hz, 1 Ø, 20 A, 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
20 A. Loads totaling more than 20 A must be
powered from an additional power supply circuit by
the use of a load relay package.

1.4.3 Outside Air Supply Blower

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 pressure switch on the pump. The load relay
package may be required with the blower. See Page
10, Figure 8 for wiring detail.

1.4.4 Pressure Switch

A pressure switch (P/N 90430600K), 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.
