Roberts Gordon Unitary Heater Installation

List of tools required for this installation - work gloves, noise protection, safety glasses, hammer or mallet, 1/4 inch hex nut driver, thin rope, socket wrench with 1/2 inch socket. Upon receiving your Roberts Gordon heater, examine the markings on the outside of the cartons prior to installation to ensure proper model, rate, gas type, heat exchanger length, and material. There are two different types of heat exchanger packages. Each package is available in various lengths. The first package, called the core package, is supplied with all unitary heaters. For lengths fifty feet and longer, an extension package is supplied. This aluminized core package contains Roberts Gordon high-efficiency reflectors. 

After properly identifying the packages, open each carton to familiarize yourself with the contents. It is recommended to open the burner carton first, as the installation and operation manual is located inside. The manual provides a pictorial view of the components that will help you identify each item. You will also find how many of each item is included in each package. Remove all contents from the burner carton. When removing the burner, confirm the information on the data plate is correct. The data plate lists the model of the burner, rate, gas type, altitude it is designed for, electrical information, serial number, along with the approval information. It is important to note that the CTH2D burner has external mounting studs. Other Roberts Gordon unitary heaters, may have separate bolts to attach the burner to the burner tube. A 36 inch long flexible gas line is included in the burner carton for US customers. The gas line is sold separately for our Canadian customers so you will not find one inside the burner carton. The burner carton will also contain the burner tube gasket, hex nuts, lock washers, pipe nipple and turbulator for select rates. 

While opening the core package, pull the cardboard just under the dashed line being careful to avoid the large staples. The core package will contain the burner tube, straight tube section, hangers, support straps and wire forms, sheet metal screws, u-clips, s-hooks, a tube clamp package, vent adapter, reflectors, reflector end caps, coupling sleeves and coupling drive bar. 

Prior to hanging the heater, identify hanging points that will properly support the weight of the heater and allow for proper spacing for hanger placement. Hanger placement is critical to allow for proper expansion and contraction of the heater. For this step, you will need a minimum of 3/16th inch chain, 3/8th inch threaded rod, or a Grippel hanging system with a minimum working load of 75 pounds per hanging point. You will also need proper anchoring to secure the chain, threaded rod or Grippel system to the building structure. These items are not supplied by Roberts Gordon. Refer to the suspension details in the Installation Manual for more information.
