SECTION 2: INTRODUCTION

2.1 About Roberts-Gordon LLC

Roberts-Gordon LLC pioneered low-intensity infrared heating systems with the introduction of its revolutionary, custom-engineered CORAYVAC

®

system.

With years of infrared expertise in commercial and industrial applications, Roberts-Gordon LLC LLC offers the CGTH-Series heater for use in 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 balanced flue. The system has been designed for easy installation and can provide years of economical operation and trouble-free service. Not only is infrared heat efficient, it also provides the most comfortable 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 (538° C) and radiates energy at a lower intensity per square foot of radiating surface. The lower temperature and intensity levels are within a range that is 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 combustion air from outdoors and exhausts the products of combustion, also to the outdoors, through a shared opening. This is accomplished through two concentric 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 key to the comfort and fuel efficiency provided by the CGTH-Series heater.

2.3 Unpacking 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/Pinch Hazard

Wear protective gear during installation, operation and service.

Edges are sharp.

Failure to follow these instructions can result in injury.

Protective gear is to be worn during installation, operation and service. Thin sheet metal parts, such as the aluminum 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.

For additional copies of the Installation, Operation and Service Manual, please contact Roberts-Gordon

LLC.

2.4 Safety Labels and Their Placement

Product safety signs or labels should be replaced by the product user when they are no longer legible.

Please contact Roberts-Gordon LLC or your ROB-

ERTS GORDON

®

independent distributor to obtain

replacement signs or labels. See Page 3, Figure 1

through Page 4, Figure 2.

2.5 California Proposition 65

In accordance with California Proposition 65 requirements, a warning label must be placed in a highly visible location on the outside of the equipment (i.e., near equipment’s serial plate). See label placement drawing on

Page 4, Figure 2 for label location. Avoid

placing label on areas with extreme heat, cold, corrosive chemicals or other elements. To order additional labels, please contact Roberts-Gordon LLC or your

plugged 1/8" NPT tapping is required upstream of the manual gas shut-off valve supplied with the heater.

FIGURE 36: Gas Supply Lines

Before connecting the heater to the supply system,

on Page 40, Figure 36, verify that all high pressure

testing of the gas piping has been completed. Do not high pressure test (greater than 1/2" psi/3.5 kPa) the gas piping with the burner connected. The appliance must be isolated from the gas piping system by closing manual gas shut-off valve during any pressure testing at pressures less than or equal to 1/2" psi (3.5 kPa).

Follow these instructions to ensure a safe gas supply system installation:

1. Support all gas piping with suitable pipe hanging materials.

2. Use wrought iron or wrought steel pipe and malleable iron fittings. The use of copper tube and brass fittings is acceptable when such use is in compliance with local codes. All pipe, tube and fittings should be new and free from defects.

Carefully ream the pipe and tube ends to remove obstructions and burrs.

3. Use LP gas resistant joint compound on all threads.

4. Check the pipe and tube connections for leaks before placing heating equipment into service.

When checking for gas leaks, use a soap and water solution; never use an open flame.

DANGER

WARNING




Heater must be connected to a properly grounded electrical source.


Turn off gas supply to heater before service.

Burn Hazard Cut/Pinch Hazard

Allow heater to cool before service.


Tubing may still be hot after operation.


Failure to follow these instructions can result in death, electric shock, injury or property damage.

1. This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. DO NOT try to light the burner by hand.

2. BEFORE OPERATING, smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

3. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.

4. DO NOT use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and replace any part of the control system and any gas control which has been under water.

12.1 Operating Instructions

STOP! Read the safety information above.

1. Set the thermostat to the lowest setting.

2. Turn off all electric power to the heater.

3. Do not try to light the burner by hand.

4. Turn off the manual gas valve in the heater supply line.

5. Wait five (5) minutes to clear out any gas. If you then smell gas, STOP! If you do not smell gas, go to the next step.

6. Open the manual gas valve in the heater supply line.

7. Turn on electric power to the heater.

8. Set the thermostat to the desired setting.

9. If the heater will not operate,

See Page 41, Sec-

tion 12.2 and call your service technician or gas

supplier.

12.2 To Turn Off Gas To Heater

1. Set the thermostat to the lowest setting.

2. Turn off all electric power to the heater if service is to be performed.

3. Turn off the manual gas valve in the heater supply line.

12.3 Sequence of Operation

1. When the thermostat calls for heat, the blower motor will energize.

ANUAL

2. When the motor approaches nominal running speed, the pressure switch closes and activates the ignition module which in turn initiates the purge.

3. The ignition module then energizes the spark igniter.

4. When sparking begins, the gas valve is energized.

5. If a flame is detected, the gas valve remains open. When the call for heat is satisfied, the system control mechanism de-energizes and the gas valve is turned off.

6. If no flame is detected, the gas valve is closed, and a purge period begins. After the purge period, the ignition module energizes the spark igniter and the gas valve. If a flame is still not established, a third and final purge/ignition sequence is begun. After three failed attempts, the system control mechanism will lock out for a period of one hour or until the unit is reset.

7. Reset is accomplished by removing power from the heater for at least five seconds.

8. With a three-try module, when the flame is established and then lost on the first or second trial, the gas valve will automatically turn off. A purge and trial for ignition will then occur.

12.4 Testing

Establish that a satisfactorily purged gas supply and an electrical supply is available to the heater.

With the gas supply turned off at the gas valve, and the electrical supply isolated by switching off at the local switch and removing the appliance electrical plug, open the control chamber secured by the four screws. Remove the sealing screw from the outlet pressure tap with a 3/16" Hex Key Allen Wrench and install a test tap and hose. Remove the cover cap from the regulator screw with a straight slot screw-

driver through the top hole of the burner.

See Page

42, Figure 37.

Turn on appliance gas valve and connect appliance electrical plug. Ensure that the timer or thermostat, if fitted, is set to call for heat. Switch on power at the local switch. If necessary, the sequence as described above, in the first and second paragraphs, should take place. If not, refer to detailed fault finding sequence. When flame is established, check the gas pressure reading and adjust if necessary. See data

label or Page 10, Section 2, for required gas pressure

setting.

Check the gas pressure at the outlet of the gas valve to ensure minimum pressure.

See Page 10, Section

4, for required gas pressure settings.

Switch off the electrical supply (shutting down the heater), remove pressure gauge and refit plug at outlet pressure tap, ensuring a tight gas seal. Replace cap and regulator screw. Close burner side cover.
