SECTION 3: INTRODUCTION
3.1 About Roberts-Gordon
Roberts-Gordon pioneered low-intensity infrared
heating systems in 1962 with the introduction of its
revolutionary custom-engineered CORAYVAC
® sys-
tem. After more than 40 years of infrared expertise in
commercial and industrial applications, Roberts-Gor-
don now offers the CGTH-Series heater for use in
residential garages and light industrial/commercial
applications.
3.2 About the Heater
The CGTH-Series is a factory-assembled, gas-fired,
low-intensity heating system that incorporates a bal-
anced flue. The system has been designed for easy
installation and will provide years of economical
operation and trouble-free service. Not only is infra-
red heat efficient, it also provides the most comfort-
able conditions in open areas, such as garages.
Gas-Fired means it uses clean-burning natural or LP
gas.
Low-Intensity means that the radiant surface of the
tube does not glow red. Instead, it operates at a
lower temperature (less than 1000°F) and radiates
energy at a lower intensity per square foot of radiat-
ing surface. The lower temperature and intensity lev-
els are within a range that is most effective in
establishing and maintaining personal comfort levels.
An aluminum reflector directs the radiant energy
downward to the occupied area.
Balanced Flue means that the burner draws com-
bustion air from outdoors and exhausts the products
of combustion, also to the outdoors, through a shared
opening. This is accomplished through two concen-
tric tubes.
Radiant refers to the energy radiated by the CGTH-
Series heater. Because the energy is in the form of
infrared rays, it does not directly heat the air. Instead,
the rays heat objects such as the floor, cars, machines
and people. The warm objects, in turn, heat the air.
These combined features are the key to the excep-
tional comfort and fuel efficiency provided by the
CGTH-Series heater.
3.3 Unpacking the Heater
3.3.1 Manpower Requirements
To prevent personal injury and damage to the heater,
two persons will be required to remove the heater
from the carton. Both ends of the heater should be
lifted from the carton at the same time. The burner
should be lifted by gripping the bottom. The reflector
of the heater should be lifted using the hanger.
3.3.2 Safety
Thin sheet metal parts, such as the reflector portion
of the heater and the various venting components,
have sharp edges. To prevent injury, the use of work
gloves is recommended. The use of gloves will also
prevent the transfer of body oils from the hands to the
surface of the reflector.
WARNING
Cut Hazard
Wear protective gloves when handling aluminum
reflectors.
Edges are sharp.
Failure to follow these instructions can result in injury.
