SECTION 1: HEATER SAFETY
Your 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 in these sections.
Installation, service and annual inspection of heater must be done by a contractor qualified in the installation and service of gas-fired heating equipment.
Read this manual carefully before installation, operation or service of this equipment.
This heater is designed for heating nonresidential indoor spaces. Do not install in residential spaces. These instructions, the layout drawing, local codes and ordinances, and applicable standards that apply to gas piping, electrical wiring, venting, etc. must be thoroughly understood before proceeding with the installation.
Protective gear is to be worn during installation, operation and service. Thin sheet metal parts, including 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.
Before installation, check that the local distribution conditions, nature of gas and pressure, and adjustment of the appliance are compatible.
This heater must be applied and operated under the general concepts of reasonable use and installed using best building practices.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do no play with the appliance.
For additional copies of the Installation, Operation and Service Manual, please contact Roberts-Gordon LLC.
To prevent personal injury and damage to the heater, two persons will be required for installation.
Product safety signs or labels should be replaced by the product user when they are no longer legible. Please contact Roberts-Gordon or your ROBERTS GORDON® independent distributor to obtain replacement signs or labels. See Page 2, Figure 1 through Page 3, Figure 2.
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 2, Figure 1 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 ROBERTS GORDON® independent distributor.

CTH2-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
The installer is responsible for the following:
•To install the heater, as well as the gas and electrical supplies, in accordance with applicable specifications and codes. Roberts-Gordon recommends the installer contact a local Building Inspector or Fire Marshal for guidance.
•To use the information given in a layout drawing and in the manual together with the cited codes and regulations to perform the installation.
•To install the heater in accordance with the clearances to combustibles.
•To furnish all needed materials not furnished as standard equipment.
•To plan location of supports.
•To provide access to burners for servicing on all sides for burner removal.
•To provide the owner with a copy of this installation, operation and service manual.
•To never use heater as support for a ladder or other access equipment and never hang or suspend anything from heater.
•To ensure there is adequate air circulation around the heater and to supply air for combustion, ventilation and distribution in accordance with local codes.
•To safely and adequately install heater using materials with a minimal working load of 75 lbs (33 kg).
•To ensure the heater is placed in a approved application.
A laminated wall tag is available for the heater as a permanent reminder of the safety instructions and the importance of the required clearances to combustibles. Please contact Roberts-Gordon or your ROBERTS GORDON® independent distributor to obtain the wall tag. Affix the tag by peeling off the backing of the adhesive strips on the rear surface and position the tag on a wall near the heater (e.g. thermostat or ROBERTS GORDON® Controller).
A copy of the wall tag (P/N 91037912) is illustrated on the back cover. For an immediate solution, you may affix this copy on the wall near the heater.
Know your model number and installed configuration. Model number and installed configuration are found
on the burner and in the Installation, Operation and Service Manual. See Page 5, Figure 3 through Page 8, Figure 12. Write the proper clearance dimensions in permanent ink according to your model number and configuration in the open spaces on the tag.
CAUTION
Product Damage Hazard
Do not use heater in area containing corrosive chemicals.
Refer to appropriate Material Safety Data Sheets (MSDS).
Failure to follow these instructions can result in product damage.
Roberts-Gordon cannot be responsible for ensuring that all appropriate safety measures are undertaken prior to installation; this is entirely the responsibility of the installer. It is essential that the contractor, the sub-contractor, or the owner identifies the presence of combustible materials, corrosive chemicals or halogenated hydrocarbons* anywhere in the premises.
* Halogenated Hydrocarbons are a family of chemical compounds characterized by the presence of halogen elements (fluorine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaning agents, solvents, etc. If these compounds enter the air supply of the burner, the life span of the heater components will be greatly reduced. An outside air supply must be provided to the burners whenever the presence of these compounds is suspected. Warranty will be invalid if the heater is exposed to halogenated hydrocarbons.
All appliances must be installed in accordance with the latest revision of the applicable standards and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in Public Garages, Aircraft Hangars, etc. may be applicable.

WARNING
Fire Hazard
Keep all flammable objects, liquids and vapors the minimum required clearances to combustibles away from heater.
Some objects will catch fire or explode when placed close to heater.
Failure to follow these instructions can result in death, injury or property damage.
• In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to the combustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a thermostat, signs must be posted in a conspicuous
location.
• Consult local Fire Marshal, Fire Insurance Carrier or other authorities for approval of proposed installation when there is a possibility of exposure to combustible airborne materials or vapors.
• Hang heater in accordance to the minimum suspension requirements on Page 14, Figure 14.
• If the radiant tubes must pass through the building structure, be sure that adequate sleeving and fire stop is installed to prevent scorching and/or fire hazard.
NOTE: 1. All dimensions are from the surfaces of all tubes, couplings and elbows.
2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream from where the burner and burner tube connect.
