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.

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.  
WARNING  
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.  
Cut Hazard  
Wear protective gloves when handling aluminum  
reflectors.  
Edges are sharp.  
Failure to follow these instructions can result in injury.  
Gas-Fired means it uses clean-burning natural or LP  
gas.  
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.  
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

WARNING  
Carbon Monoxide Hazard  
Heater must be exhausted outside.  
Use materials supplied.  
• Heaters in aircraft storage or service areas must be  
installed a minimum of 10' (3 m) above the upper  
surface of wings or engine enclosures of the highest  
aircraft which may be housed in the hangar. (This  
should be measured from the bottom of the heater  
to the top of the wing, or engine enclosure, which-  
ever is highest from the floor).  
This heater needs fresh air for safe  
operation and must be installed so  
there are provisions for adequate  
combustion and ventilation air.  
Failure to follow these instructions  
can result in death or injury.  
The location, size, installation and termination of  
vents, as well as the required safe distances from  
combustibles when penetrating combustible walls,  
must comply with local codes and recommendations  
of the local gas company. United States: Refer to  
National Fuel Gas Code, ANSI Z223.1 - latest revi-  
sion (same as NFPA 54). Canada: Refer to CSA  
B149.1 Natural Gas ans Propane Installation Code.  
• In other sections of aircraft hangars, such as shops  
or offices, heaters must be installed a minimum of 8'  
(2.4 m) above the floor.  
• Heaters installed in aircraft hangars shall be located  
so as not to be subject to damage by aircraft,  
cranes, movable scaffolding or other objects.  
• When installed over hoists, the required safe dis-  
tances from combustibles must be maintained from  
the uppermost point of the combustible materials  
placed on the hoist.  
4.4.2 Balanced Flue Construction  
The balanced flue consists of a 3" (8 cm) diameter  
flue which is concentrically positioned inside a 5"  
(12.5 cm) diameter vent pipe (See Figure 2). The 5"  
(12.5 cm) diameter vent supplies outside air for com-  
bustion while the 3" (8 cm) diameter flue carries the  
products of combustion from the heater.  
4.5.2 Public Garages  
The CGTH-Series heater may be used in public  
garages. Installation in public garages must be in accor-  
dance with the following codes: United States: Standard

below the heater.  
• Sufficient clearances will exist to allow for easy  
access to the service door.  
• When installed over hoists, the required safe dis-  
tances from combustibles must be maintained from  
the uppermost point of the combustible materials  
placed on the hoist.  
• Overhead structural members (rafters, beams, etc.)  
are accessible for attaching the heater.  
4.5.3 Hazardous Locations  
Where there is the possibility of exposure to combus-  
tible airborne material or vapor, consult the local Fire  
Marshal, the Fire Insurance Carrier or other authori-  
ties for approval of the proposed installation.  
4.6 Heater Location  
It is the Installer’s Responsibility to choose a suitable  
mounting location for the heater. The Installer must  
follow the guidelines below as stated in the Installa-  
tion Manual. Before using your heater, check the  
location. If the location does not follow these guide-  
lines, do not use the heater. Immediately contact  
your installer.  
• The heater must meet the minimum mounting  
height requirement of 7' (2.1 m) above the floor. For  
aircraft hangars and public garages, the heater must  
meet the minimum mounting height requirement of  
8' (2.4 m) above the floor.  
• The proposed mounting location allows for the  
required safe distances from combustibles such as  
vehicles, wood, gasoline and flammable objects, liq-  
uids and vapors.  
• The proposed location of the heater will not restrict  
motion of passageway doors or windows.  
• The proposed location will not interfere with opera-  
tion of the overhead garage door, or allow the door  
to enter the required safe distances from combusti-  
bles.  
• The proposed location will provide the best cover-  
age of the total area to be heated.  
• Consideration be given to the types of vehicles that  
will be parked in the garage (cars, vans, boats, RV's,  
etc.).  
• The proposed location will allow for the required safe  
distances from combustibles with respect to the  
vehicles parked in the garage.  
• The proposed location will allow the required utilities  
(i.e.: gas and electric) and venting to be installed  
(maximum vent length is 10' [3 m]).

ically lights the burner. DO NOT try to light the  
burner by hand.  
2. BEFORE OPRERATING 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.  
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.

CGTH USE AND CARE MANUAL  
2. Turn off all electric power to the heater if service  
is to be performed.  
7. Reset is accomplished by removing power from  
the heater for at least five seconds.  
3. Turn off the manual gas valve in the heater  
supply line.  
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.  
5.7 Venting  
5.6 Sequence of Operation  
As mentioned on Page 5, Section 3.7, it is the  
Installer’s Responsibility to properly vent (exhaust)  
the heater outside. Please make sure your heater is  
vented. If it is not vented, do not use the heater.  
Immediately call your installer.  
Your heater may be vented in one of three ways:  
horizontal through the wall, horizontal with an elbow  
through the wall or vertical through the roof. You  
should know the way your heater is vented. Refer to  
the following drawings to determine the type of vent-  
ing you have. If you are not sure, please contact your  
installer.  
1. When the thermostat calls for heat, the blower  
motor will energize.  
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 ener-  
gized.  
5. If a flame is detected, the gas valve remains  
open. When the call for heat is satisfied, the sys-  
tem control mechanism de-energizes and the  
gas valve is turned off.  
WARNING  
Carbon Monoxide Hazard  
Heater must be exhausted outside.  
Use materials supplied.  
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.  
This heater needs fresh air for safe  
operation and must be installed so  
there are provisions for adequate  
combustion and ventilation air.  
Failure to follow these instructions  
can result in death or injury.
