Failure to follow these instructions can result in death or electrical shock. WARNING Explosion Hazard Turn off gas supply to heater before service. Failure to follow these instructions can result in death, injury or property damage. There are several methods of controlling CRV-Series systems. The options are as follows: 8.1 ROBERTS GORDON® System Control (P/N 02770002) The ROBERTS GORDON® System Control is an electronic controller designed for the control of CORAYVAC® and VANTAGE® NP (multiburn

Reflectors can be used over the manifold tube but are not required. The system design parameters are such that the manifold sections are not subjected to condensate when the system is fully heated up. It is required that heat-treated aluminized or coated tubing is used for the manifold to increase system life and to handle initial condensation during start-up. Damper couplings may be necessary to balance system vacuum. Design requirements for a CTHN multiburner system are summarized on Page 30,

6.1 Prior to Operation Prior to operation of the pump in the heating system, operation and proper rotation of the impeller must be verified. IMPORTANT: Improper rotation of the impeller will not produce the vacuum required for proper system operation. The EP-201 motor must be wired for clockwise or counterclockwise rotation as shown on Page 12, Figure 11. The EP-201 motor is wired for 1 O, 120 V, 60 Hz operation. The EP-201 motor can be rewired for 230 V operation by changing the motor connectio
