CGTH INSTALLATION, OPERATION AND SERVICE MANUAL

SECTION 2: INTRODUCTION 2.1 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.

2.2 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-Firedmeans it uses clean-burning natural or LP gas.

Low-Intensitymeans 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.

2.3Unpacking the Heater 2.3.1 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.

2.3.2 Safety

WARNING

Cut Hazard

Wear protective gloves when handling aluminum reflectors.

Edges are sharp.

Failure to follow these instructions can result in injury.

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.
